Abstract
CONTEXT Anti-Müllerian hormone (AMH) measured in adolescence as biomarker for prediction of adult polycystic ovary syndrome (PCOS) is doubtful but not substantiated. OBJECTIVE To investigate whether serum AMH levels and other PCOS-associated features in adolescence can predict the presence of PCOS in adulthood. DESIGN AND SETTING A long-term follow-up study based on a unique adolescent study on menstrual irregularities performed between 1990 and 1997. PARTICIPANTS AND INTERVENTIONS AMH was assayed in 271 adolescent girls. Data on PCOS features were combined with AMH levels. In 160 of the 271 (59%) participants, we collected information in adulthood about their menstrual cycle pattern and presence of PCOS (features) by questionnaire 2 decades after the initial study. RESULTS AMH was higher in adolescent girls with oligomenorrhea compared with girls with regular cycles, median (interquartile range): 4.6 (3.1-7.5) versus 2.6 (1.7-3.8) μg/L (P < 0.001). Women with PCOS in adulthood had a higher median adolescent AMH of 6.0 compared with 2.5 μg/L in the non-PCOS group (P < 0.001). AMH at adolescence showed an area under the receiver operating characteristic curve for PCOS in adulthood of 0.78. In adolescent girls with oligomenorrhea the proportion developing PCOS in adulthood was 22.5% (95% CI, 12.4-37.4) against 5.1% (95% CI, 2.1-12.0) in girls with a regular cycle (P = 0.005). Given adolescent oligomenorrhea, adding high AMH as factor to predict adult PCOS or adult oligomenorrhea was of no value. CONCLUSIONS Adolescent AMH either alone or adjuvant to adolescent oligomenorrhea does not contribute as prognostic marker for PCOS in adulthood. Therefore, we do not recommend routine its use in clinical practice.

Abstract
PCOS is one of the most common endocrine disorders and NAFLD is one of its most dangerous metabolic consequences. The diagnosis of NAFLD is not a practical task and the condition is at risk of being overlooked. The use of simpler but still reliable surrogate markers is necessary to identify women with a high likelihood of NAFLD. The aim of this study was to evaluate the clinical correlates of NAFLD Liver Fat Score (NAFLD-LFS) in women with oligomenorrhea and/or hirsutism. Furthermore, the study aimed to evaluate whether, among the hormonal parameters evaluated in such women, possible hallmarks of NAFLD may be identified. To this purpose, 66 women who attended our Outpatient Clinic for oligomenorrhea and/or hyperandrogenism were included in the study. In order to validate the results obtained in the first cohort, a second independent sample of 233 women evaluated for female sexual dysfunction (FSD) was analyzed. In cohort 1, NAFLD-LFS positively correlated with metabolic and inflammatory parameters. Among the hormone parameters, NAFLD-LFS showed no significant relationships with androgens but a significant negative correlation with SHBG (p<0.0001) that therefore appeared as a candidate hallmark for pathologic NAFLD-LFS. The ROC analysis showed a significant accuracy (81.1%, C.I.69.1-93.0, p <0.0001) for SHBG in identifying women with a pathological NAFLD-LFS. In particular, a SHBG 33.4 nmol/l was recognized as the best threshold, with a sensitivity of 73.3% and a specificity of 70.7%. In order to validate this SHBG as a marker of metabolic impairment possible related with the presence of NAFLD, we tested this threshold in cohort 2. FSD women with SHBG <33.4 nmol/l had worse metabolic parameters than women with SHBG ≥33.4 nmol/l and a significantly higher NAFLD-LFS even after adjusting for confounders (B=4.18 [2.05; 6.31], p=0.001). In conclusion, this study provides a new evidence in the diagnostic process of NAFLD, showing that the measurement of SHBG, which is routinely assessed in the workup of women referred for possible PCOS, could identify women at higher metabolic risk, thus detecting those who may deserve further targeted diagnostic assessment.

Abstract
Non-classical congenital adrenal hyperplasia (NC-CAH) includes a group of genetic disorders due to a broad class of CYP21A2 variants identifying a disease-causing 'C' genotype. The heterozygous carriers of CYP21 mutations are at increased risk of developing clinically evident hyperandrogenism, even though clinical and laboratory characteristics are still underestimated. With the aim of obtaining a more accurate delineation of the phenotype of heterozygous carrier of CAH, we analyzed clinical, biochemical and molecular characteristics in a cohort of Sicilian subjects. Fifty-seven females with biallelic and monoallelic CYP21A2 variants classifying NC-CAH (24) and heterozygous carriers of CAH (33), respectively were selected. Forty-four females age-matched healthy controls were also enrolled and genotyped for CYP21A2. Clinical, hormonal and genetic data were collected. CYP21A2 monoallelic mutations, defining the heterozygous carriers state, were identified in subjects with clinical features including hirsutism, oligomenorrhoea, overweight and a PCO-like phenotype, particularly occurring in the age of adolescence. Consistently, levels of 17OHP and cortisol were found to be significantly different from NC-CAH. Overall, some clinical and laboratory findings including oligomenorrhea and 17OHP/cortisol ratio were observed as independent markers associated with carriers of CAH. Here we report a high prevalence of late-onset signs of polycystic ovary syndrome (PCOS) and hyperandrogenism in heterozygous carriers. The 17OHP/cortisol ratio may be a predictive tool to identify the carriers of CAH, even though specific cut-off values have not yet been identified.

Abstract
Background To develop a diagnostic assessment tool, using clinical, biochemical and sonographic markers, to help clinicians in the differential diagnosis of functional oligomenorrhea (FO) and endocrine-metabolic oligomenorrhea (EMO). Methods Sixty-two adolescents with oligomenorrhea without evident hormonal imbalances or severe energy deficit were selected. They were divided into two groups (EMO and FO) and they all underwent the following assessment: physical examination (height, weight, presence of hirsutism or acne), blood exams and transabdominal ultrasonography. The biochemical markers included: hemoglobin, thyrotropin stimulating hormone (TSH), prolactin (PRL), follicle stimulating hormone (FSH), luteinizing hormone (LH), free (FT) and total testosterone (TT), androstenedione (A), dehydroepiandrosterone sulfate (DHEAS) and sex hormone binding globulin (SHBG). Uterine and ovarian volume, ovarian morphology, endometrial thickness and pulsatility index (PI) of uterine arteries were evaluated with ultrasound. Results Body mass index (BMI), hemoglobin, LH levels and LH/FSH ratio were significantly higher in women with EMO than in those with FO. Increased androgens values were found in the EMO group, but only A and FT were significantly different (p=0.04). Ovarian volume and uterine artery PI were the only ultrasound features significantly different, with higher values in the EMO population (p<0.05). Considering these variables, with a receiving characteristic operating curve, new cut-offs were calculated, and a diagnostic assessment tool elaborated (area under curve [AUC] 0.88, specificity 99%, sensibility 59%, p<0.001]. Conclusions This diagnostic tool, specific for adolescents, could be useful in the management of oligomenorrhea. Recognizing and distinguishing EMO and FO is very important in order to establish an appropriate treatment and a correct follow-up.

Abstract
INTRODUCTION Vitamin D (VD) plays a crucial role in calcium metabolism as well as immunological and endocrine homeostasis. Previous studies revealed strong inverse correlation between VD levels and insulin resistance, parathyroid dysfunctions and autoimmune thyroid disease. Insufficient evidence concerns its dependency of ovarian hormones. Malfunctioning of the ovaries results in menstrual disorders that are one of the most common endocrine impairments in young women of reproductive age. MATERIAL AND METHODS The study was aimed to evaluate the correlation between 25(OH)D serum concentration and estradiol, testosterone as well as body mass index (BMI) in women with oligomenorrhea. 134 women of reproductive age with oligomenorrhea were eligible for the study. 25-hydroxyvitamin D [25(OH)D], estradiol, testosterone and sex hormone-binding globulin (SHBG) were measured using chemiluminescence immunoassay. Free androgen index (FAI) and body mass index (BMI) were calculated. RESULTS Critical 25(OH)D deficiency (<10 ng/ml) was found in 13.4% of women, the risk of deficiency (<30 mg/dl) was diagnosed in 69.4%, while sufficient level of VD (>30 mg/ml) in 17.2% of them. Significant negative correlation was detected between 25(OH)D and estradiol serum concentrations (r=-0.2; p=0.049), as well as BMI levels (r=-0.22; p=0.01). However, no significant correlation was found between 25(OH)D and testosterone (r=-017; p=0.055), SHBG (r=0.08; p=0.4) and FAI (r=-0.1; p=0.24). CONCLUSIONS Thorough assessment of vitamin D deficiency/insufficiency is required among patients with menstrual disorders, especially those overweighed and obese. Early screening and VD supplementation in women with estrogen-dependent disorders may become a part of routine management in order to optimize endocrine health.

Abstract
Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine and metabolic disorder, characterized by chronic anovulation/oligomenorrhea, hyperandrogenism, and insulin-resistance. Moreover, some studies propose a possible association between insulin resistance and hyperhomocysteinemia, which is a significant long-term risk for factor for atherogenesis and chronic vascular damage, especially in situations where insulin levels are increased. Insulin-sensitizing agents are used in the treatment of PCOS: in fact, inositols were shown to have insulin-mimetic properties. Synergic action to myo-inositol is that of gymnemic acids that have antidiabetic, anti-sweetener, and anti-inflammatory activities. Gymnemic acid formulations have also been found useful against obesity due to their ability to delay the glucose absorption in the blood. L-methyl-folate increases peripheral sensitivity to insulin, maintaining folatemia stable, and thus restoring normal homocysteine levels. Unlike folic acid, L-methyl folate has a higher bioavailability, no drug/food interferences, high absorption, and it is stable to UV-A exposure. The aim of our study is to compare the clinical, endocrine, and metabolic parameters in 100 PCOS women treated with myo-inositol, gymnemic acid, and l-methylfolate (Group A) or myo inositol and folic acid only (Group B), continuously for 6 months. From a clinical point of view, it was noticed a more significant improvement of the menstrual cycle regularity and a more significant reduction of BMI in Group A. Moreover, a more significant decrease of total testosterone and increase of SHBG serum levels were noticed in Group A. The metabolic assessment found a more significant decrease of total cholesterol and homocysteine levels; OGTT glycemia and insulinemia values were significantly more improved after treatment with myo-inositol + gymnemic acid. In conclusion, we can state that a good option for the treatment of PCOS is the combined administration of myo-inositol + gymnemic acid + l-methyl-folate, especially for overweight/obese patients with marked insulin resistance and with associated hyperhomocysteinemia.

Abstract
Obesity has adverse effects on ovulation, menstrual cyclicity and oocyte development leading to clinical symptoms such as infertility and menstrual disorders. The Roux-en-Y gastric bypass (RYGB) leads to weight loss, improved insulin sensitivity and may improve ovarian function. In 31 premenopausal women, 18 eu- and 13 oligo-/amenorrhoic, we followed the changes in follicular phase sex hormones 3, 6 and 12 month after RYGB. The average weight loss during the first postoperative year was 39.6 kg. The insulin sensitivity and serum insulin improved markedly especially within the first three postoperative months. SHBG increased progressively and was doubled after 12 months. In contrast, total and free androgens and DHEA declined about 50% during the first three postoperative months and remained fairly constant hereafter. One year after surgery, 85% (11/13) of the women with oligo-/amenorrhea gained regular menstrual cycles. Our results indicate that some of the endocrine changes related to regulation of ovarian function occur very early after bariatric surgery.

Abstract
BACKGROUND Primary amenorrhea, oligomenorrhea and secondary amenorrhea are diagnosed commonly during adolescence. Weight aberrations are associated with menstrual disorders. Autoimmune thyroiditis is frequent during adolescence. In this study, the commonest clinical and hormonal characteristics of amenorrhea or oligomenorrhea during adolescence were investigated. METHODS In this cross-sectional study, one hundred and thirty-eight consecutive young patients presenting with amenorrhea or oligomenorrhea referred to an adolescent endocrinology and gynecology university clinic were studied. Clinical examination and an abdominal ultrasound were performed. Testosterone, free-testosterone, estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), dehydroepiandrosterone sulfate (DHEA-S), 17-OH progesterone, sex hormone binding globulin (SHBG), Δ4-androstenedione (Δ4A), free androgen index (FAI), insulin, glucose, thyroid stimulating hormone (TSH), total thyroxine (T4) (TT4), free T4 (FT4), total triiodothyronine (T3) (TT3) and free T3 (FT3). Concentrations were measured in blood samples. RESULTS Patients with primary and secondary amenorrhea presented more often with body mass index (BMI) <18.5 and BMI >25 kg/m2, respectively. BMI values correlated positively with insulin (r=0.742) and glucose (r=0.552) concentrations and negatively with glucose/insulin ratio values (r=-0.54); BMI values and insulin concentrations correlated positively with FAI values (r=0.629 and r=0.399, respectively). In all patients, BMI values correlated positively and negatively with free testosterone (r=0.249) and SHBG (r=-0.24) concentrations, respectively. In patients with secondary amenorrhea insulin concentrations correlated negatively with SHBG concentrations (r=-0.75). In patients with oligomenorrhea BMI values correlated positively with insulin (r=0.490) and TSH (r=0.325) concentrations, and negatively with SHBG (r=-0.33) concentrations. Seventy-two percent, 21% and 7% of patients presented with TSH concentrations <2.5 μIU/mL, between 2.5 μIU/mL, 4.5 μIU/mL and >4.5 μIU/mL (subclinical hypothyroidism), respectively. Following the definition of polycystic ovary syndrome (PCOS) according to either the National Institutes of Health (NIH) criteria or those proposed in the literature by Carmina and his team, patients presented mainly with oligomenorrhea or secondary amenorrhea. There was good agreement between patients with amenorrhea or oligomenorrhea fulfilling both of the PCOS definition criteria employed. CONCLUSIONS Among adolescent patients presenting with amenorrhea or oligomenorrhea for the first time those with low and high BMI present more often with primary and secondary amenorrhea, respectively. Obesity is involved in the development of hyperandrogenemia and hyperinsulinemia, particularly in PCOS patients. In these patients, subclinical hypothyroidism may be concealed and it should be investigated. These patients should be treated for abnormally increased or decreased BMI and be investigated for autoimmune thyroiditis.

Abstract
The aim of this study was to evaluate and compare the effects of spironolactone and spironolactone plus metformin treatments on body mass index (BMI), hirsutism score, hormone levels, and insulin resistance in women with polycystic ovary syndrome (PCOS). Thirty-seven patients with PCOS were randomly assigned to receive spironolactone 100 mg/d (spironolactone group, 18 patients) or spironolactone 100 mg/d plus metformin 2000 mg/d (combination group, 19 patients) for 12 months. BMI, modified Ferriman-Gallway score (FGS), serum levels of regarding hormones, and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed before and after the treatments. Six patients in the spironolactone group and four patients in the combination group reported inter-menstrual vaginal bleeding during treatments. In hirsutism scores, the spironolactone therapy resulted in 25.2% reduction, while combination therapy resulted in 28.3% reduction (p > 0.05, between groups). When the groups were compared in terms of percent changes in BMI, FGS, HOMA-IR, and hormone values other than free testosterone, no significant difference was noted. In the present study, FGSs were significantly decreased in both groups; however, combination therapy was not more effective than spironolactone alone in terms of BMI, FGS, hormone levels, or insulin resistance.

Abstract
The objective was to investigate whether the associations between leptin, adiponectin, andadiposity reported in classic polycystic ovary syndrome (PCOS) are also observed in elderly women with a novel putative postmenopausal PCOS phenotype. We studied 713 postmenopausal community-dwelling women. Diagnosis of the novel phenotype required the presence of ≥3 diagnostic features including: 1) a personal history of oligomenorrhea; 2) history of infertility or miscarriage; 3) current or past clinical or hormonal evidence of hyperandrogenism; 4) central obesity; 5) biochemical evidence of insulin resistance. Women in the control group had ≤2 of these components. Mean age (±SD) was 74±8 years for the study cohort. Sixty-six women (9.3%) had the putative PCOS phenotype. Serum leptin was higher (mean 25.70±15.67 vs 14.94+9.89 ng/mL, P<.01) and adiponectin lower (mean 11.72±4.80 vs 17.31±7.45 μg/mL, P<.01) in cases vs controls. Leptin was positively, and adiponectin inversely, associated with an increasing number of phenotype features (P<.01 for linearity). In age-adjusted regression analysis, adjustment for waist circumference eliminated the association between leptin and the PCOS phenotype, but not the association between adiponectin and the PCOS phenotype. In this novel postmenopausal PCOS phenotype, adipocytokine profiles and their associations with adiposity parallel those reported in younger women with classic PCOS. These results support our hypothesis that a putative phenotype analogous to PCOS can be identified in postmenopausal women using clinical and biochemical criteria. Use of this novel phenotype could provide a basis for studies of the delayed consequences of PCOS in older women.

Abstract
OBJECTIVE The aim of this study was to describe the endocrine and metabolic characteristics of Chinese women with polycystic ovarian syndrome (PCOS) according to different phenotypes, including menstrual cycle pattern and body mass index (BMI). DESIGN Retrospective study. PATIENT(S) A total of 3539 patients with PCOS and 590 controls were recruited from the Centre for Reproductive Medicine. Patients with PCOS were divided into three groups according to the characteristics of the menstrual cycle (amenorrhoea, oligomenorrhea and eumenorrhea) and the BMI (<25 kg/m(2) ; 25 ≤ and ≤ 30 kg/m(2) ; and BMI > 30 kg/m(2) ). MEASUREMENTS Waist circumference, hip circumference, weight, height, Ferriman-Gallwey score, and endocrine and metabolic variables were measured. RESULTS The serum testosterone, luteinizing hormone (LH) and oral glucose tolerance test 2 h-glucose levels were increased in the amenorrhoea group (P < 0·05). The triglycerides (TG) and low-density lipoprotein-cholesterol (LDL) levels were the highest in the amenorrhoea group (P < 0·05). The same trend existed in total cholesterol and non- high-density lipoprotein-cholesterol (HDL) levels, although there was no statistical significance (P > 0·05). Subjects with a BMI<25 kg/m(2) had higher values of follicle stimulating hormone (FSH), LH, LH/FSH and prolactin (P < 0·001) than the other two groups. The levels of TG, LDL and non-HDL and the indices of glucose and insulin metabolism increased with the change in BMI (P < 0·001). CONCLUSIONS The amenorrhoea group had severe endocrine and metabolic abnormalities, which appeared to be related to latent long-term complications and higher morbidity. The degree of dysbolism was positively associated with the change in BMI.

Abstract
CONTEXT In women with polycystic ovary syndrome (PCOS), the basis for ovarian androgen overproduction involves an overall increase of steroidogenesis, notably in the delta-4 pathway. However, in vitro studies have suggested that excessive androgen production occurs predominantly through the delta-5 pathway. OBJECTIVE This study was performed to assess androgen dose-responses after human chorionic gonadotropin (hCG) stimulation in PCOS and normal women. DESIGN We conducted a prospective study to compare androgen production after iv hCG in PCOS and normal women. SETTING The study was conducted in a General Clinical Research Center in an academic medical center. PARTICIPANTS Women with PCOS (age, 18-37 yr; n = 10) and normal ovulatory controls (age, 18-37 yr; n = 11) were recruited. INTERVENTIONS For dose-response studies, blood samples were obtained before and at 0.5, 24, and 48 h after iv recombinant hCG (1, 10, 25, 100, and 250 μg). A subset of subjects underwent frequent blood sampling over 24 h after iv injection of 25 μg of recombinant hCG. MAIN OUTCOME MEASURE(S) We measured basal and stimulated serum 17-hydroxyprogesterone (17-OHP), androstenedione (A), testosterone (T), dehydroepiandrosterone, estradiol, and progesterone responses after hCG administration. RESULTS In PCOS women, maximal A and T production was observed at the lowest doses of hCG, whereas responses were minimal in normal women. Incremental responses of 17-OHP, estradiol, and progesterone were greater in PCOS compared to normal women. CONCLUSION In PCOS women, maximal A and T responses to hCG relative to those of 17-OHP are consistent with ovarian androgen overproduction via the delta-5 pathway.

Abstract
OBJECTIVE As increased frequency of gonadotrophin-releasing hormone (GnRH) pulses is characteristic for polycystic ovary syndrome (PCOS), we assessed gonadotrophin response to GnRH in women with PCOS with normal and raised androgens and in regularly menstruating controls. DESIGN, PATIENTS AND METHODS The study involved 155 subjects: PCOS, n=121, age (mean±SD) 24.8±5.4 yrs, BMI 24.5±6.0 kg/m2, all with oligo-/amenorrhoea and PCO morphology, and 34 controls. Gonadotrophins were measured in early follicular phase after GnRH stimulation (0, 30 and 60 minutes). RESULTS Fifty four (41.9%) women with PCOS had androgens (testosterone, androstendione, dihydroepiandrosterone sulphate) within the reference range, and would fulfil the "Rotterdam", but not the Androgen Excess Society PCOS criteria. Baseline and stimulated LH concentrations were higher in PCOS (9.09±5.56 vs 4.83±1.71 IU/l, 35.48±31.4 vs 16.30±6.68 IU/l, 33.86±31.8 vs 13.45±5.2 IU/l, at 0, 30 and 60 min post GnRH, respectively, p<0.0001). An LH/FSH ratio in PCOS increased further after GnRH stimulation. ROC analysis revealed that LH30min/FSH30min >2.11 or LH60min/FSH60min >1.72 had 78.3% and 87.5% sensitivity and 81.7% and 81.3% specificity for diagnosis of PCOS. Both baseline and GnRH-stimulated LH and FSH concentrations were similar in women with PCOS and raised androgens and with androgens within the reference range (p=0.71 and p=0.20 for LH and FSH, respectively). CONCLUSIONS Regardless of their androgen status, women with PCO morphology and oligo-/amenorrhoea have higher baseline and GnRH-stimulated LH concentrations and higher GnRH-stimulated LH/FSH ratio than controls, suggestive of similar underlying mechanism accounting for menstrual irregularities. These observations support validity of PCOS diagnostic criteria based on the Rotterdam consensus.

Abstract
CONTEXT Serum anti-Müllerian hormone (AMH) levels are significantly elevated in adolescents with polycystic ovary syndrome (PCOS) compared to normal controls. Whether adolescents with oligomenorrhea have elevated AMH levels is unknown. OBJECTIVE This study was performed to assess serum AMH levels in oligomenorrheic (OLIGO) girls without evidence of hyperandrogenism. DESIGN This was a prospective study comparing AMH levels in OLIGO, PCOS, and normal control adolescents. SETTING The study was conducted through four tertiary academic medical centers. PARTICIPANTS The study groups were comprised of OLIGO (n = 24), PCOS (n = 153), and normal adolescent girls (n = 39), as well as PCOS (n = 73) and normal adult women (n = 36). INTERVENTIONS In each subject, serum AMH levels were assessed in the early to midfollicular phases for regularly menstruating subjects and on an arbitrary day for OLIGO or PCOS subjects. MAIN OUTCOME MEASURE(S) Basal serum AMH levels were assessed among OLIGO, PCOS, and normal girls, in addition to PCOS and normal women. RESULTS OLIGO girls had serum AMH levels (5.33 +/- 0.47 ng/ml) that were significantly greater than the normal adolescents (3.05 +/- 0.31 ng/ml) and adults (2.33 +/- 0.22 ng/ml), but similar to values seen in the PCOS adolescents (5.28 +/- 0.26 ng/ml) and adults (6.36 +/- 0.47 ng/ml). Obese adolescents and PCOS women had significantly lower AMH levels compared to lean controls (P < 0.02). CONCLUSION In OLIGO adolescents, elevated serum AMH levels suggest increased antral follicle number similar to that observed in girls with PCOS.

Abstract
OBJECTIVE The objective of the study was to characterize the bioactivity of prolactin (PRL) in hyperprolactinaemic patients with prolactinomas, irregular menstrual cycles, regular menstrual cycles and PCOS. METHODS Serum PRL, biological activity of PRL (after polyethylene glycol (PEG) precipitation) and serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), thyroid-stimulating hormone (TSH) concentrations were measured in all hyperprolactinaemic patients and control group (healthy subjects). Correlations between active PRL (PRL-PEG) and serum FSH, LH, E2, T, TSH concentrations were also evaluated. RESULTS Prolactinoma is characterized by high serum PRL levels and its high biological activity. Hyperprolactinaemic patients with irregular cycles were characterized by high biological activity of PRL. Patients with hyperprolactinaemia and regular cycles had low biological activity of PRL. CONCLUSIONS Diagnosis of hyperprolactinaemia should be associated with estimation of PRL biological activity because it is important for type of hyperprolactinaemia management. Low biological activity of PRL does not impair FSH and LH secretion and does not cause hypoestrogenism.

Abstract
Hirsutism, acne, alopecia, and oligo-amenorrhea are clinical expressions of hyperandrogenism, one of the most frequent endocrine disorders in women of reproductive age. Women referred to our endocrine clinics for skin symptoms of hyperandrogenism underwent a laboratory workup to evaluate hormone measurements and received antiandrogen therapy. We retrospectively analyzed the outcome of 228 consecutive patients investigated over 6 years.Patients with hirsutism had higher levels of androstenedione, dehydroepiandrosterone sulfate (DHEAS), and salivary testosterone; lower levels of sex hormone-binding globulin (SHBG); and a higher prevalence of oligo-amenorrhea than patients with alopecia, while patients with acne showed intermediate values. Hirsutism score correlated positively with androstenedione, DHEAS, and salivary testosterone, and correlated negatively with SHBG; salivary testosterone showed the highest correlation coefficient. Total testosterone was not significantly different among patients with hirsutism, alopecia, or acne, and did not significantly correlate with hirsutism score. Hirsutism and oligo-amenorrhea were the most sensitive symptoms of hyperandrogenism, and no androgenic parameter alone allowed us to identify all cases of hyperandrogenism.Patients of central European origin sought consultation with milder hirsutism scores than patients of southern European origin. There was, however, no difference in the clinical-biological correlation between these groups, arguing against differences in skin sensitivity to androgens.Polycystic ovary syndrome, defined as hyperandrogenism (hirsutism or elevated androgens) and oligo-amenorrhea, was diagnosed in 63 patients (27.6%), an underestimate compared with other reports that include systematic ovarian ultrasound studies. Neither pelvic ultrasound, used in a limited number of cases, nor the luteinizing hormone/follicle-stimulating hormone ratio helped to distinguish patients with polycystic ovary syndrome from the other diagnostic groups. These included hyperandrogenism (hirsutism or elevated androgens) and eumenorrhea (101 patients; 44.3%); normal androgens (acne or alopecia and eumenorrhea) (51 patients; 22.4%); isolated low SHBG (7 patients; 3.1%); nonclassical congenital adrenal hyperplasia (4 patients; 1.8% of total, 4.9% of patients undergoing cosyntropin stimulation tests); and ovarian tumor (2 patients; 0.9%).Ethinylestradiol and high-dose cyproterone acetate treatment lowered the hirsutism score to 53.5% of baseline at 1 year, and was also effective in treating acne and alopecia. The clinical benefit is ascribed to the peripheral antiandrogenic effect of cyproterone acetate as well as the hormone-suppressive effect of this combination. Salivary testosterone showed the most marked proportional decrease of all the androgens under treatment. Cost-effectiveness and tolerance of ethinylestradiol and high-dose cyproterone acetate compared well with other antiandrogenic drug therapies for hirsutism. The less potent therapy with spironolactone only, a peripheral antiandrogen without hormone-suppressive effect, was effective in treating isolated alopecia in patients with normal androgens.

Abstract
CONTEXT Polycystic ovary syndrome (PCOS) is a common endocrinopathy of uncertain etiology but with strong evidence for a genetic contribution. OBJECTIVE The objective of the study was to test the hypothesis that the typical polycystic ovarian morphology is a marker of inherited biochemical features in families of women with PCOS. DESIGN A study of probands with PCOS and their sisters. PATIENTS Patients included 125 probands and 214 sisters. All probands had PCOS, defined by symptoms of anovulation and/or hyperandrogenism with polycystic ovaries on ultrasound. Affected sisters were defined by polycystic ovaries, regardless of symptoms, and unaffected sisters defined by normal ovarian morphology. SETTING This was a clinic-based study. MAIN OUTCOME MEASURES Clinical, endocrine, and metabolic features in the various groups were compared, and estimates of broad-sense heritability were obtained using the quantitative transmission disequilibrium test. RESULTS Although affected sisters had fewer symptoms than probands (30% had no symptoms of PCOS), serum testosterone, androstenedione, LH, and fasting insulin and insulin sensitivity were similar in the two groups with polycystic ovaries but significantly different from those in unaffected sisters or controls. We observed moderate to high heritabilities for all traits studied in affected sister pairs, whereas heritabilities calculated from discordant siblings were substantially lower. CONCLUSIONS These data provide further evidence for a genetic basis of PCOS. The high heritability of biochemical features in probands and affected sisters, despite wide variation in symptoms, shows that not only are these biochemical traits strongly influenced by genetic factors but also, importantly, that polycystic ovarian morphology is an index of inherited traits in families with PCOS.

Abstract
BACKGROUND Any abnormality of menstrual cycle makes women worried and requires proper evaluation. Oligomenorhea is one of the indicators of Polycystic Disease of the Ovary (PCO) which is associated not only with reproductive failure but it also has metabolic and cardiovascular complications. The recent study was conducted to find out the role of Pituitary Gonadotropins in the diagnosis. After diagnosing and finding out the cause for menstrual irregularities and chronic anovulation one can explain the prognosis and management of these disorders. METHODS Fifty patients were studied in the year 2005-06 in the outpatient department of Khyber Teaching Hospital Peshawar. A history Performa was duly completed in all subjects. Blood sample was collected for hormonal essay during first ten days of the cycle. Hormonal essay was performed by Microparticle enzyme immunoassay (MEIA) on AXSYM system of Abbott. RESULTS Age ranged from 13-45 years, 82% of the women were infertile, 60% had infrequent periods and 22% of the women had amenorrhea, 30% patients were overweight while 48% were obese. Physical examination revealed hersuitism in 24%, acne in 8% and galactorrhea in 6% of the patients. Ultrasound examination showed classical picture of PCO in 28% patients while 32% women had multiple small follicles and 16% women were devoid of follicles. Elevated LH levels were found in 36% women. FSH level were found normal in 64% patients while in 16% women the levels were in menopausal range. LH/FSH ratio of more than two was observed in 52% women. Prolactin level was raised in 22% women. TSH level was below normal in 16% and higher in 22% women. CONCLUSION Hormonal essays are mandatory in the evaluation of women presenting with Oligomenorhea/amenorrhea and chronic anovulatory infertility for finding out the cause and explaining the prognosis of the disease to the patient.

Abstract
OBJECTIVE Menstrual cycle disturbances frequently occur during the onset or in exacerbation periods of systemic lupus erythematosus (SLE), suggesting a possible relationship. The aim of the study is to assess the ovarian function in SLE patients with active disease before the treatment with high doses of glucocorticoids (GC) and cytotoxic agents. METHODS We evaluated 94 female SLE patients (mean age of 29.2+/-7.0 years). The mean SLEDAI score was 11.4+/-8.1. Seventy-nine patients had a current use of GC with a median dose of 10 mg/day (8-15). The other 15 patients were untreated. After examination and blood sample collection 40% of the patients were treated and high doses of GC (>30 mg/day); 68% from this group of patients were treated GC in combination with cyclophosphamide (CYC). Forty healthy women with the same mean age were evaluated as controls. A careful gynecological history and a gynecological examination were carried out in patients and controls. Hormonal serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, estradiol (E2) and progesterone in SLE patients and controls were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS Menstrual cycle disorders with oligomenorrhea as dominant aspect were observed in 54% of SLE patients. The hormonal studies showed decreased progesterone level in 52% of patients, reduced E2 concentration in 25% of patients; increased levels of LH, FSH and prolactin were observed with the lower frequency (13%, 9%, 10% respectively). Menstrual cycle disorders and the hormonal unbalance such as decreased progesterone level and hyperprolactinemia were found related significantly to high SLEDAI score (p<0.05, p=0.001, p<0.05). In the group of non-treated SLE patients the menstrual and hormonal disorders were observed in the same spectrum and with the same frequency as in all the examined SLE patients. SLEDAI score was found correlated significantly with the frequency of menstrual cycle disorders in non-treated SLE patients (p<0.05). CONCLUSION The reported study shows the disease activity as a major factor associated with menstrual cycle disorders in SLE patients before treatment with alkylating agents and high doses of GC. Therefore, SLE women might be considered as a risk group for altered ovarian function.

Abstract
Oligomenorrhea and polycystic ovaries in women are one of the most important causes of the high incidence of ovulation failure. This is linked, perhaps, to insulin resistance and related metabolic features. A small number of reports show that myo-inositol improves ovarian function, but in these trials the quality of evidence supporting ovulation is suboptimal. Furthermore, few of them have been placebo-controlled. The aim of our study was to use a double-blind, placebo-controlled approach with detailed assessment of ovarian activity (two blood samples per week) to assess the validity of this therapeutic approach in this group of women. Of the 92 patients randomized, 47 received 400 mcg folic acid as placebo, and 45 received myo-inositol plus folic acid (4 g myo-inositol plus 400 mcg folic acid). The ovulation frequency assessed by the ratio of luteal phase weeks to observa-tion weeks was significantly (P < 0.01) higher in the treated group (25%) compared with the placebo (15%), and the time to first ovulation was significantly (P < 0.05) shorter [24.5 d; 95% confidence interval (CI), 18, 31; compared with 40.5 d; 95% CI, 27, 54]. The number of patients failing to ovulate during the placebo-treatment period was higher (P < 0.05) in the placebo group, and the majority of ovulations were characterized by normal progesterone concentrations in both groups. The effect of myo-inositol on follicular maturation was rapid, because the E2 circulating concentration increased over the first week of treatment only in the myo-inositol group. A significant increase in circulating high-density lipoprotein was observed only in the myo-inositol-treated group. Metabolic risk factor benefits of myo-inositol treatment were not observed in the morbidly obese subgroup of patients (body mass index > 37). After 14-wk myo-inositol or placebo therapy, no change in fasting glucose concentrations, fasting insulin, or insulin responses to glucose challenge was recorded. There was an inverse relationship between body mass and treatment efficacy. In fact a significant weight loss (and leptin reduction) (P < 0.01) was recorded in the myo-inositol group, whereas the placebo group actually increased weight (P < 0.05). These data support a beneficial effect of myo-inositol in women with oligomenorrhea and polycystic ovaries in improving ovarian function.

Abstract
OBJECTIVES AND METHODS In 100 anovulatory infertile women with polycystic ovary syndrome attending the infertility clinic of this institute, transvaginal ultrasound findings of ovaries were correlated with both clinical and hormonal parameters using Chi-square test. RESULTS All women in the study had oligomenorrhea or amenorrhea, 70% had hirsutism and more than half were obese. On transvaginal ultrasound, ovarian volume was more than 10 cm3 in all, 90% had more than 10 follicles in each ovary, 75% had stromal thickness more than 1 cm and more than half had increased stromal echogenicity. Seventy percent had high testosterone levels and 60% were detected to have insulin resistance. Ovarian volume correlated positively with body mass index, waist/hip ratio and menstrual cycle irregularity (p < 0.05). The correlation between ovarian size, LH/FSH ratio and hyperinsulinemia was highly significant (p < 0.005), but was low for serum androgens and also hirsutism. Number of follicles per ovary correlated positively with body mass index, menstrual irregularity (p < 0.01), insulin resistance as well as androgens (p < 0.005). Positive predictive value of ovarian follicle number was 100% for insulin resistance as well as D4 androstenedione. Increased stromal thickness also showed 70% positive prediction for clinical parameters, 66% for insulin resistance and 82% for serum D4 androstenedione. Contrary to the other ultrasound parameters of polycystic ovary, stromal echogenicity did not significantly correlate with any of the clinical or hormonal parameters except serum testosterone. CONCLUSION Transvaginal ultrasonography of the ovaries confirms the clinical profile and also gives an insight to the hormonal milieu of the women with PCOS.

OBJECTIVE Data concerning bone mineral density (BMD) in bulimia nervosa are contradictory and include both low and normal values. The aim of the present study was to elucidate possible endocrine-and nutrition-related factors predicting BMD in bulimic women. DESIGN Cross-sectional study. METHODS Seventy-seven bulimic patients and 56 age- and body mass index (BMI)-matched healthy controls were examined with respect to BMD (dual energy X-ray absorptiometry) and to serum levels of hormones and metabolic factors. RESULTS Bulimics had significantly lower spinal BMD and higher frequency of osteopenia in the total body than controls. Furthermore, bulimic women had significantly lower levels of estradiol-17beta and free thyroxine and significantly higher cortisol levels compared with controls. Among the bulimics, 31.2% had present menstrual disturbance, 51.9% had a history of amenorrhea and 23.4% had previous anorexia nervosa. Subgroups of bulimics with a history of amenorrhea and previous anorexia nervosa had significantly lower total and spinal BMD than controls, whereas those without such history did not differ from the controls. In univariate analysis, a history of amenorrhea, cortisol, testosterone, previous anorexia nervosa, and BMI showed significant associations with spinal BMD. Multiple regression analysis including all significant variables revealed previous anorexia nervosa to be the strongest determinant of spinal BMD, accounting for 34% of the variance, while associations between endocrine factors and BMI disappeared. CONCLUSIONS Low bone mass in bulimics may be explained by previous anorexia nervosa, whereas endocrine variables related to BMD seem to be secondary determinants that are dependent on previous anorexia nervosa and BMI.

Abstract
OBJECTIVE To determine whether obese, nonhirsute adolescents with oligomenorrhea exhibit similar increased LH pulse secretion patterns compared with obese girls with polycystic ovary syndrome (PCOS). DESIGN Prospective, observational study. SETTING Tertiary university hospital. PATIENT(S) Nine obese girls with oligomenorrhea, 15 with PCOS, and 10 controls. INTERVENTION(S) Twenty-four-hour IV blood sampling for LH (every 10 minutes); measurement of steroid hormones (every 12 hours); and injection of leuprolide acetate (10 microgm/kg SC). MAIN OUTCOME MEASURE(S) Twenty-four-hour, wake, and sleep LH mean serum concentration, pulse frequency, amplitude; steroid hormones, including free androgen index (FAI); and pre- and post-leuprolide acetate 17-hydroxyprogesterone measurements. RESULT(S) Twenty-four-hour LH pulse frequency in oligomenorrheic girls (18.6 +/- 1.2) (mean +/- SE) was comparable to that in girls with PCOS (20.9 +/- 0.7) and greater than in normal girls (13.4 +/- 0.8). The pulse number during both sleep and wake was identical in oligomenorrheic and PCOS girls and significantly greater than that of normal girls. Mean 24-hour LH level, serum androgen levels, and FAI in oligomenorrheic girls were equivalent to those of normal controls and lower than those of PCOS girls. CONCLUSION(S) These preliminary results indicate that obese girls with oligomenorrhea exhibit increased LH pulse frequency in the absence of clinical and/or biochemical evidence of hyperandrogenism.

Abstract
INTRODUCTION Matrix metalloproteinases (MMPs) have been implicated in various pathological processes including inflammatory response, cardiovascular disease, and recently also in ovarian dysfunction. Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age and is characterized by chronic anovulation, insulin resistance, and increased prevalence of cardiovascular risk factors. Circulating levels of MMPs and their tissue inhibitors (TIMPs) so far have not been assessed in the PCOS. MATERIALS AND METHODS Serum levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 were measured in 23 women with PCOS [age (mean +/- sd), 30.5 +/- 6.7 yr; body mass index, 35.8 +/- 7.5 kg/m2] and 22 healthy, regularly menstruating women (age, 29.4 +/- 5.6; body mass index, 31.7 +/- 9.2 kg/m2). RESULTS Women with PCOS had significantly higher concentrations of MMP-2 (999.8 +/- 155 vs. 521.8 +/- 242 ng/ml; P < 0.001), MMP-9 (592.4 +/- 279 vs. 345 +/- 309; P = 0.007), and TIMP-1 levels (823.8 +/- 145 vs. 692 +/- 210 ng/ml; P = 0.02) than control healthy women. There was no difference in TIMP-2 levels (47.3 +/- 30 vs. 44.4 +/- 39.7 ng/ml; P = 0.21) between women with PCOS and controls. CONCLUSIONS Obese women with PCOS have elevated serum concentrations of MMP-2 and -9. It might be hypothesized that elevated MMP concentrations may be related to increased cardiovascular risk in PCOS and/or menstrual irregularities associated with this syndrome.

Abstract
OBJECTIVE Our aim was to compare physical activity and biochemical markers with bone mineral acquisition in rhythmic gymnasts and ballet dancers. METHODS Weight, height, body mass index, nutritional intake, bone age and menstrual histories were analyzed in nine rhythmic gymnasts, twelve ballet dancers and fourteen controls. Bone mineral density (BMD) was assessed by X-ray absorptiometry at the lumbar spine, hip and radius. Bone alkaline phosphatase (bAP) and amino-terminal propeptide of procollagen I (PNIP) in serum and urinary alpha-isomer of the carboxy-terminal telopeptide of collagen I (alpha-CTX) were measured. RESULTS Bone age was delayed 2 years and mean age at menarche was 15+/-0.9 years in rhythmic gymnasts and 13.7+/-1 years in ballet dancers, compared with 12.5+/-1 years in controls. Trocanteric and femoral neck BMD was significantly higher in rhythmic gymnasts compared with ballet dancers and controls. Right forearm (non-loaded zone) BMD was significantly decreased in rhythmic gymnasts and ballet dancers compared with controls. All subjects had normal bAP and PNIP levels, but the alpha-CTX/creatinine (Cr) ratio was increased in rhythmic gymnasts (P<0.001) with an inverse correlation between right forearm BMD and the alpha-CTX/Cr ratio (r=-0.74, P<0.001). Serum leptin levels were decreased in rhythmic gymnasts and ballet dancers. Rhythmic gymnasts had a positive correlation between right forearm BMD and leptin levels (r=0.85, P<0.001). CONCLUSIONS Decreased bone mass in rhythmic gymnasts could be partially explained by an increase in bone resorption. Serum leptin levels could be implicated in the pubertal delay and be a good marker of bone mass in these subjects.

Abstract
The endocrinological profile of 20 strenuously exercising oligomenorrheic adolescents divided into 2 groups (groups A and B), was correlated with that of 10 athletes (group C) with normal menstrual cycles and without strenuous exercise. Group A LH serum baseline values were found to be statistically significantly lower than those of group C (P less than 0.001). FSH/LH basic values were 1.9- and 2.9-times higher in group A athletes than those of group B or C (P less than 0.05 and P less than 0.001, respectively). 17 beta-estradiol (E2) and prolactin serum levels were found lower in group A and B athletes than those of group C (P less than 0.01-0.05). Dehydroepiandrosterone sulfate and delta 4 androstenedione serum levels were found lower in group A athletes than those of group C (P less than 0.001). The low LH and E2 values indicate the anovulatory status of group A and B cases which were also confirmed by ultrasound. It is concluded that no severe endocrinological changes exist in strenuously exercising oligomenorrheic athletes in relation to menarche.

Abstract
OBJECTIVE The LH response of pituitary gland to gonadotropin-releasing hormone (GnRH) stimulation is not well defined in patients with mutant beta-subunit (Trp(8) to Arg(8) and Ile(15) to Thr(15)). Here we compared the relative activities and dynamics of LH secretion in patients with wild-type and variant LH following injection of GnRH. METHODS A GnRH stimulation test was performed in 33 patients with ovulatory disorders (patient group) and 29 women with normal ovulatory cycles (control group) heterozygous for the variant LHbeta allele. Blood samples were obtained up to 120 min after GnRH injection. Serum LH response was determined by comparing the results of LH immunoassays using a monoclonal antibody that recognizes wild-type LH only with those of another assay using a polyclonal antibody that recognizes equally both variant and wild-type LH (total LH). The ratio of variant LH to total LH (LH ratio) was used to determine the serum LH status. RESULTS The LH ratio in the control group showed the peak 15 min after GnRH injection, while that in the patient group showed the peaks 30-60 min after injection. The LH ratio in the patient group at 120 min after injection was significantly lower than that in the control group. The percent increases in LH ratio in both groups showed the peak 15 min after injection. The patient group had significantly lower changes of LH ratio at 15, 60, 90 and 120 min after GnRH injection compared with that in the control group. CONCLUSION Differences in circulatory kinetics of the two types of LH may explain the differences in LH function between patients with ovulatory disorders and women with normal ovulatory cycles.

Abstract
OBJECTIVE To evaluate endocrine mechanisms underlying oligomenorrhea or amenorrhea in female athletes. DESIGN Cross-sectional study. SETTING Women's health clinical research unit at a university hospital. PATIENT(S) Age- and BMI-matched groups of athletes active in endurance sports with and without menstrual disturbances and regularly cycling sedentary controls. INTERVENTION(S) Groups were compared with respect to endocrine status, body composition, and physical performance. MAIN OUTCOME MEASURE(S) Identification of a subgroup of oligomenorrheic or amenorrheic athletes with increased androgen levels and anabolic body composition. RESULT(S) A subgroup of 8 of 25 athletes with menstrual disturbances had significantly higher serum levels of free and total testosterone, androstenedione, LH-FSH ratio, and lower SHBG levels than did all other groups. Other oligomenorrheic or amenorrheic athletes had normal values comparable to those in regularly menstruating athletes and controls. The hyperandrogenic subgroup showed a more anabolic body composition, with higher total bone mineral density and upper-lower fat mass ratio than did oligomenorrheic or amenorrheic athletes with normal androgen levels. The hyperandrogenic subgroup had the highest VO2 max and the highest performance values in general. CONCLUSION(S) Menstrual disturbances in female athletes are often explained as a consequence of hypothalamic inhibition and caloric deficiency. We suggest that essential hyperandrogenism is an alternative mechanism underlying oligomenorrhea or amenorrhea in some female athletes and may imply an advantage for physical performance.

Abstract
The hormonal profiles of nested female patients (n = 500) with self-reported symptoms typical of polycystic ovary syndrome (PCOS), oligomenorrhea, and/or hirsutism and their randomly selected controls (n = 1026) at the age of 31 yr were analyzed in a general population-based Northern Finland birth cohort 1966 to find out whether the symptomatic women also have the endocrine characteristics of PCOS and could be detected in a general population using simple questions. Higher medians of serum testosterone (T) (2.10 vs. 1.90 nmol/liter, P < 0.001), LH (5.40 vs. 4.85 U/liter, P = 0.005), insulin (53.8 vs. 51.66 pmol/liter, P = 0.040), and free androgen index (FAI) (4.01 vs. 3.03, P < 0.001) and lower glucose/insulin ratio (91.1 x 10(8) vs. 94.9 x 10(8), P = 0.048) and SHBG (52.4 vs. 60.7 nmol/liter, P < 0.001) were observed among the cases, but no difference was observed in cortisol and glucose levels between the cases and controls. Of all the women in the cohort, 10.2% reported only oligomenorrhea and had biochemical findings similar to the whole case group. Those who reported only hirsutism (10.4%) were in between the case and control groups according to biochemical findings. The subjects who reported both oligomenorrhea and hirsutism (3.4%) had the highest T, LH, FAI, insulin, and glucose and the lowest SHBG and glucose/insulin ratio, compared with the case group and the groups with either symptom only indicating a dose-response manner in typical endocrine profile of PCOS by adding up symptoms. The levels of T and FAI were higher and SHBG lower in groups with overweight or obesity both at 14 and 31 yr, compared with groups with normal weight at 14 yr and overweight or obesity at 31 yr. In the group with normal weight at 14 and 31 yr and the group with overweight or obesity at 14 yr but normal weight at 31 yr, the levels of T and FAI were lowest and SHBG highest. T and FAI were higher and SHBG lower among the cases than the controls in groups stratified by weight development from adolescence to adulthood. In conclusion, this longitudinal study of a large, stable population indicates that women with self-reported symptoms of hirsutism and/or oligomenorrhea show endocrine characteristics of PCOS and can be detected in a general population using simple questions. These symptoms are markers of the underlying metabolic alterations possibly associated with increased health risks in later life.

Abstract
OBJECTIVE To establish whether initial screening characteristics of normogonadotropic anovulatory infertile women can aid in predicting live birth after induction of ovulation with clomiphene citrate (CC). DESIGN Prospective longitudinal single-center study. SETTING Specialist academic fertility unit. PATIENT(S) Two hundred fifty-nine couples with a history of infertility, oligoamenorrhea, and normal follicle-stimulating hormone (FSH) concentrations who have not been previously treated with any ovulation-induction medication. INTERVENTION(S) 50, 100, or 150 mg of oral CC per day, for 5 subsequent days per cycle. MAIN OUTCOME MEASURE(S) Conception leading to live birth after CC administration. RESULT(S) After receiving CC, 98 (38%) women conceived, leading to live birth. The cumulative live birth rate within 12 months was 42% for the total study population and 56% for the ovulatory women who had received CC. Factors predicting the chances for live birth included free androgen index (testosterone/sex hormone-binding globulin ratio), body mass index, cycle history (oligomenorrhea versus amenorrhea), and the woman's age. CONCLUSION(S) It is possible to predict the individual chances of live birth after CC administration using two distinct prediction models combined in a nomogram. Applying this nomogram in the clinic may be a step forward in optimizing the decision-making process in the treatment of normogonadotropic anovulatory infertility. Alternative first line of treatment options could be considered for some women who have limited chances for success.

Abstract
PURPOSE The aim of this study was to investigate BMD in Danish female elite gymnasts and the relationships to maximal muscle strength, sex hormone concentrations, and menstrual status. METHODS Six artistic gymnasts, five rhythmic gymnasts, and six controls aged 15-20 yr served as subjects. BMD (g x cm(-2)) of lumbar spine, proximal femur, distal radius, and whole body were measured by dual-energy x-ray absorptiometry (DXA) scanning. Maximal muscle strength (Nm) was measured in isokinetic trunk extension, trunk flexion, and knee extension. Serum concentrations of estrogen and progesterone in follicular and luteal phases were evaluated. RESULTS Three out of six artistic gymnasts had amenorrhea, and two artistic and one rhythmic gymnast experienced oligomenorrhea. BMD in artistic gymnasts was greater than controls (24-45%, P < 0.05) in all sites except whole body. BMD in rhythmic gymnasts was greater than controls (4-26%, P < 0.05) in all sites except distal radius. In gymnasts, BMD correlated to both maximal muscle strength (0.60 < r < 0.85, P < 0.05) and serum progesterone (0.65 < r < 0.75, P < 0.05). CONCLUSION In spite of oligomenorrhea or amenorrhea, it is possible for female gymnasts to maintain a high BMD in both the axial (L2-L4) and appendicular skeleton. The correlations between BMD and maximal muscle strength and progesterone concentration in gymnasts may indicate that within the same athletic group, progesterone concentration has a permissive role in bone formation, thus affecting the positive impact of muscle strength.

Abstract
OBJECTIVE To predict the FSH response (threshold) dose in normogonadotropic, anovulatory infertile women undergoing gonadotropin induction of ovulation. DESIGN Prospective longitudinal clinical study. SETTING Specialist academic fertility unit. PATIENT(S) Normogonadotropic, oligoamenorrheic, infertile women who were resistant to clomiphene citrate or in whom clomiphene citrate therapy had failed. INTERVENTION(S) Daily exogenous FSH administration in a low-dose, step-up regimen. MAIN OUTCOME MEASURE(S) The FSH dose on the day of ovarian response (follicle growth > 10 mm in diameter). RESULT(S) Multivariate analysis was used to devise the following equation to predict the individual FSH response dose (75 to >187 IU/d) before initiation of therapy: [4 body mass index (in kg/m(2))] + [32 clomiphene citrate resistance (yes = 1 or no = 0)] + [7 initial free insulin-like growth factor-I (in ng/mL)] + [6 initial serum FSH level (in IU/L)] - 51. The SE of the predicted dose is 35 IU. CONCLUSION(S) The individual FSH response dose for gonadotropin induction of ovulation in anovulatory infertile women can be predicted on the basis of initial screening characteristics. The prediction model developed in this study may increase the safety and efficiency of low-dose gonadotropin protocols (step-up and step-down) by correctly determining the appropriate starting dose for a given patient.

Abstract
OBJECTIVE The aim of this study was to investigate if ageing women with polycystic ovary syndrome (PCOS) who gained regular menstrual cycles differed from women who continued to menstruate irregularly with regard to risk factors for developing diabetes mellitus and atherosclerosis. DESIGN AND PATIENTS In the original study of a population of 346 PCOS patients, defined in the past as having oligo- or amenorrhoea and elevated LH concentrations, we had sent out a questionnaire to investigate changes in the pattern of their menstrual cycles while ageing. From this cohort of patients, a significantly older group of 53 women (mean age: 41.3 years, range: 33.3-49.4) who were not using oral contraceptives or other hormones visited the outpatient clinic. These women did not differ from the non-participating group in BMI, ethnic origin, the proportion with regular menstrual cycles by age group, parity or the use of clomiphene citrate or gonadotrophins in the past. MEASUREMENTS A physical examination and a transvaginal ultrasound were performed. The size of the follicle cohort was determined by counting the number of small follicles in the ovaries. Thirty-four women were also willing to give two fasting blood samples for measuring their glucose, insulin and lipid status. RESULTS Forty-one of the 53 (77.4%) women had a regular menstrual cycle (shorter than 6 weeks) and 12 (22.6%) had an irregular cycle (longer than 6 weeks). The body mass index (BMI), waist: hip ratio (WHR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and prevalence of diabetes (1-9%) and hypertension (11.3%) did not differ between the two menstrual cycle groups. Also, the fasting glucose, insulin, glucose/insulin ratio, total cholesterol, HDL-c, and LDL-c concentrations did not show any significant difference between the two groups. Instead, these parameters all were significantly higher in women with a BMI > 27 kg/M2 compared to women with a BMI < or = 27 kg/m2. Regularly menstruating PCOS women were older (P < 0.01), showed less follicles in their ovaries (n = 48, P < 0.01) and had lower androgens (n = 34, P < 0.05) than the irregularly menstruating women. Logistic regression analysis showed a second significant influence, after age, of the BMI on the menstrual cycle pattern (age, P < 0.01; BMI, P < 0.05). If age was excluded from the analysis, only the follicle count significantly predicted the menstrual cycle pattern (P < 0.02). CONCLUSIONS We conclude that hyperinsulinaemia, dyslipidaemia and hypertension in our population of ageing women with polycystic ovary syndrome are not related to the menstrual cycle pattern but rather to obesity. Age and the size of the follicle cohort are the main factors determining the menstrual cycle pattern in ageing women with polycystic ovary syndrome, although an association with the BMI was also found.

Abstract
OBJECTIVE To evaluate whether some ultrasound parameters of ovarian morphology can discriminate between control women and patients with polycystic ovary syndrome (PCOS). DESIGN Retrospective data analysis. SETTING Volunteers women in an academic research environment. PATIENT(S) Eighty amenorrheic or oligomenorrheic women and 30 normal ovulatory control participants. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) We evaluated ovarian volume, area, stroma, and the stroma/total area (S/A) ratio by use of transvaginal pelvic ultrasound; and we assayed serum levels of gonadotropin, androgen, and estradiol during the early follicular phase (days 2 to 5) of the menstrual cycle in regularly cycling controls and on a random day in amenorrheic patients. RESULT(S) Patients with PCOS showed significantly higher ovarian volume, area, stroma, and mean S/A ratio when compared to multifollicular and control groups. Cut-off values have been defined for ovarian volume (13.21 mL), area (7.00 cm2), stroma (1.95 cm2), and S/A ratio (0.34). The sensitivity for PCOS diagnosis was 21%, 4%, 62%, and 100%, respectively. The S/A ratio showed the most significant correlation with the androgen levels. CONCLUSION(S) The evaluation of the S/A ratio can differentiate between PCOS and control or multifollicular women with both a sensitivity and a specificity of 100%. Furthermore, this ultrasound parameter is strictly related to hormonal milieu and to anthropometric characteristics.

Abstract
PURPOSE Strenuous training can be associated with amenorrhea leading to amenorrhea-related accelerated bone loss. Insufficient calorie energy, calcium, and/or protein intakes can also be frequently encountered in women with intense training, possibly contributing to bone loss. Long-distance runners with or without regular menses (age range 19-37 yr) were prospectively studied. METHODS Changes in areal bone mineral density (BMD) were measured at 1-yr interval. RESULTS Among 10 eumenorrheic, 11 oligo-amenorrheic, and 9 oral contraceptive users, there was no difference in energy, calcium, or protein intakes. Baseline BMD values were significantly lower in the oligo-amenorrheic group than in the two others at the level of lumbar spine (anteroposterior view: 0.941+/-0.039 in oligo-amenorrheic vs 1.077+/-0.029 or 1.051 +/-0.017 g x cm(-2), P < 0.005, in the eumenorrheic and contraceptive user groups, respectively) but not in weight-bearing bone such as proximal and midshaft femur. Over a 1-yr interval, during which the three groups did not differ in terms of running distances and dietary intakes, oligo-amenorrheic women displayed a significant decrease in lumbar spine BMD in lateral view (-0.049+/-0.012 in oligo-amenorrheic vs -0.001+/-0.013 and 0.014+/-0.012 g x cm(-2), p < 0.005, in the eumenorrheic and contraceptive user groups, respectively). We did not detect any significant change in femoral neck, trochanter, or midshaft BMD. CONCLUSIONS Oligo-amenorrhea in long-distance runners, with adequate dietary intakes, was associated with a decrease in BMD affecting more the lumbar spine than the proximal and midshaft femur during a 1-yr follow-up.

Abstract
Precocious pubarche in girls is often preceded by low weight at birth and followed by hirsutism, ovarian hyperandrogenism, and oligomenorrhea in adolescence, the latter usually being accompanied by dyslipidemia and hyperinsulinism, which are, in turn, two major risk factors for cardiovascular disease in later life. We hypothesized that insulin resistance may be a key pathogenetic factor in this sequence. We tested the hypothesis by assessing the effects of an insulin-sensitizing agent, metformin, given at a daily dose of 1275 mg for 6 months to 10 nonobese adolescent girls (mean age, 16.8 yr; body mass index, 21.9 kg/m2; birth weight, 2.7 kg) with hirsutism, ovarian hyperandrogenism (diagnosis by GnRH agonist test), oligomenorrhea, dyslipidemia, and hyperinsulinemia after precocious pubarche. Before the metformin trial, longitudinal studies in these girls had shown that hyperinsulinism was present at prepubertal diagnosis of precocious pubarche, and that it increased markedly in late puberty or early postmenarche. Metformin treatment was well tolerated and was accompanied by a marked drop in hirsutism score, insulin response to oral glucose tolerance test, free androgen index, and baseline testosterone, androstenedione, dehydroepiandrosterone, and dehydroepiandrosterone sulfate levels (all P < 0.01). During metformin treatment, the LH and 17-hydroxyprogesterone hyperresponses to GnRH agonist were attenuated (P < 0.01); serum triglyceride, total cholesterol, and low density lipoprotein cholesterol levels decreased; and high density lipoprotein cholesterol rose. All girls reported regular menses within 4 months. Withdrawal of metformin treatment was followed, within 3 months, by a consistent reversal toward pretreatment conditions. In conclusion, metformin treatment reduced hyperinsulinemia, hirsutism, and hyperandrogenism; attenuated the LH and 17-hydroxyprogesterone hyperresponses to GnRH agonist; improved the atherogenic lipid profile; and restored eumenorrhea in nonobese adolescent girls with a history of precocious pubarche. These observations corroborate the idea that insulin resistance may indeed be a prime factor underpinning the sequence from reduced fetal growth, through precocious pubarche, to adolescent endocrinopathies that are reminiscent of so-called polycystic ovary syndrome.

Abstract
BACKGROUND In the skin, the expression of androgen action is dependent on the reduction of testosterone to dihydrotestosterone mediated by the enzyme 5 alpha-reductase. Additionally, an exaggeration of this peripheral metabolism has been associated with acne in women. METHODS Fifty-two women with acne vulgaris but without hirsutism were recruited in this study, including 42 with oligomenorrhea or amenorrhea (Group 1) and 10 with regular menstrual cycles (Group 2). As a control, another 15 oligomenorrheic women without acne were also studied (Group 3). Flutamide combined with sequential estrogen-progestogen preparations was given to patients in Group 1. In Group 2, flutamide alone was administered. In Group 3, the women were treated with sequential estrogen-progestogen. RESULTS In Groups 1 and 2, a significant decrease in the number of inflammatory lesions was found at the end of 3 and 6 months of treatment, and even after discontinuation of therapy for 6 months. Before treatment, patients in Group 1 showed signs of biochemical hyperandrogenism, including elevated levels of serum testosterone (T), androstenedione (A), and dehydroepiandrosterone sulfate (DHEA-S), as well as a decreased level of sex hormone-binding globulin (SHBG). A decrease in circulating T and A, and an elevation in serum SHBG were found 3 and 6 months after treatment in Group 1. In Group 2, clinical improvement of acne was achieved by flutamide alone without alteration in circulating androgens (including T, A, and DHEA-S). Similarly, no change in serum androgens was observed in the women of Group 3 after treatment. CONCLUSION A low dose of flutamide (250 mg/day) in association with or without estrogen-progestogen is effective for the clinical improvement of acne vulgaris in women with or without oligomenorrhea or amenorrhea. However, the effectiveness on hyperandrogenic symptoms by antiandrogens may or may not be reflected by the suppression of serum androgens.

Abstract
Hospital based studies have shown that oligomenorrhoeic adolescents have high luteinizing hormone (LH) and androgen concentrations, endocrine signs of polycystic ovary syndrome (PCOS). The prevalence of these abnormalities in an unselected population of adolescents is not known. We determined LH, follicle stimulating hormone (FSH), androstenedione, testosterone, dehydroepiandrosterone sulphate (DHEAS), oestradiol and prolactin concentrations in unselected population samples of adolescents with oligomenorrhoea, secondary amenorrhoea and regular menstrual cycles. A total of 2248 white, west European adolescents, aged 15.3 +/- 0.6 (mean +/- SD) years, participated. Blood was taken from 107 adolescents with regular menstrual cycles, 52 with oligomenorrhoea and four with secondary amenorrhoea. Oligomenorrhoeic adolescents had higher mean LH, androstenedione, testosterone, DHEAS and oestradiol concentrations compared with girls with regular menstrual cycles; 57% of the oligomenorrhoeic girls had LH or androgen concentrations above the 95th centile of adolescents with regular menstrual cycles. None of the 52 oligomenorrhoeic girls and only one of four girls with secondary amenorrhoea had a hypogonadotrophic endocrine pattern. The present study and available literature support the view that oligomenorrhoea in adolescents is not a stage in the physiological maturation of the hypothalamic pituitary-ovarian axis but an early sign of PCOS associated with subfertility. Physicians should consider endocrine evaluation before reassuring oligomenorrhoeic girls or prescribing oral contraceptives to these girls.

Abstract
We measured luteinizing hormone (LH) and androgen concentrations in patients at different phases of the oligomenorrhoeic cycle and compared the results with those of patients with normogonadotrophic amenorrhoea. Several blood samples separated by >/=7 days were obtained from each of 72 patients with oligomenorrhoea and 18 with normogonadotrophic amenorrhoea. The oligomenorrhoeic cycle was divided into five phases: the postmenstrual phase week 1 (day 1-7) and week 2 (day 8-14), the specific oligomenorrhoeic phase (SOP, day 15 after a menstruation to day 21 before the next menstruation), the possibly peri-ovulatory phase (days 21-11 before menstruation) and the premenstrual phase (days 10-1 before menstruation). Samples obtained in the possibly peri-ovulatory phase were excluded. Within individuals LH concentrations were significantly higher during the SOP than during all other phases of the oligomenorrhoeic cycle (paired t-test, P = 0.0001-0.03). In contrast to the other phases of the oligomenorrhoeic cycle, no significant differences in gonadotrophins, androgen or oestradiol concentrations were found between the SOP and normogonadotrophic amenorrhoea. In oligomenorrhoea timing of blood sampling influences the measurement of LH and androgen concentrations, and the accurate interpretation of these measurements requires that the dates of menstruation both before and after the sample is taken should be known. In patients with oligomenorrhoea blood samples should be obtained during the SOP, when the endocrinology is comparable with that of normogonadotrophic amenorrhoea.

Abstract
OBJECTIVES Most thyroid textbooks describe hypothyroidism resulting in changes in the length of the menstrual cycle and in the amount of bleeding. Our experience at a busy thyroid clinic had given a picture which differs from that presented in the literature. The aim of this study was to determine the frequency and type of menstrual irregularities in premenopausal hypothyroid patients. DESIGN AND PATIENTS We investigated the menstrual history, starting 6 months before the discovery of the disease, in 171 female premenopausal hypothyroid patients and 214 normal controls, with similar age and body mass index (BMI). MEASUREMENTS TSH, TT4, TT3 and thyroid antibodies were measured by radioimmunoassay, while BMI was calculated from the ratio of body weight in kg to height in m2. RESULTS Of the 171 hypothyroid patients, 131 (76.6%) had regular cycles and 40 (23.4%) irregular periods. Oligomenorrhoea and menorrhagia were the most common features in the latter group. No difference in BMI was found between the patients with or without menstrual abnormalities, or between patients and controls. TSH, TT4 and TT3 levels did not differ between patients with normal and abnormal menstruation. Forty-six (26.9%) out of 171 patients had subclinical hypothyroidism (group A), 42 (24.6%) mild hypothyroidism (group B) and 83 (48.5%) severe hypothyroidism (group C). Thirty-seven from group A (80.4%), 32 from group B (76.2%) and 62 from group C (74.7%) had normal periods. These differences were not statistically significant. Eighty-eight (88.9%) out of 99 patients in whom thyroid antibodies were measured had positive titres. Nineteen (21.6%) of the patients with positive thyroid antibodies had menstrual irregularities. This percentage did not differ from that found in the whole group of patients (23.4%). Out of 214 normal controls, 196 (91.6%) had normal menstruation and 19 (8.4%) irregular cycles. The latter group included mainly women with oligomenorrhoea. CONCLUSIONS These data demonstrate that hypothyroidism in women is less frequently associated with menstrual disturbance than was previously described. Also, menstrual irregularities tend to be more frequent in sever hypothyroidism in comparison with mild cases, although this finding was not statistically significant. Oligomenorrhoea and menorrhagia are the most common menstrual disturbances.

Abstract
OBJECTIVE To evaluate [1] the effects of levels of sex hormone-binding globulin (SHBG), albumin, and total testosterone on the distribution of testosterone between SHBG-bound and non-SHBG-bound fractions; [2] the independent effects of polycystic ovary syndrome (PCOS) and body mass index on serum levels of total testosterone, non-SHBG-bound testosterone, SHBG, and albumin; and [3] the usefulness of levels of total testosterone and non-SHBG-bound testosterone and of the free androgen index in the diagnosis of PCOS. DESIGN Retrospective clinical study. SETTING An academic research environment. PATIENT(S) Forty-three women with oligomenorrhea and PCOS. Twenty-five women with regular menstrual cycles and without hirsutism served as controls. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Levels of non-SHBG-bound testosterone, total testosterone, SHBG, and albumin in serum. RESULT(S) Levels of total testosterone and non-SHBG-bound testosterone, and the free androgen index were higher in patients with PCOS than in healthy controls. PCOS did not have an effect on the levels of SHBG or albumin, or on the percentage of non-SHBG-bound testosterone. Levels of SHBG and albumin were inversely related to body mass index. The percentage and concentration of non-SHBG-bound testosterone and the free androgen index were directly related to body mass index. Hirsutism did not have an effect on any outcome measure. CONCLUSION(S) The distribution of total testosterone into SHBG-bound and non-SHBG-bound fractions is associated with body mass index, not with PCOS. The high levels of non-SHBG-bound testosterone and the high free androgen index in patients with PCOS reflect mainly high levels of total testosterone. Thus, the measurement of levels of non-SHBG-bound testosterone and the calculation of the free androgen index provide no further information in the diagnosis of PCOS beyond that provided by the measurement of levels of total testosterone.

Abstract
The clinical relevance of the free androgen index (FAI), a ratio of total testosterone (T) to sex-hormone binding globulin (SHBG), was investigated in a regional population of men (n = 40) and women (n = 30). The FAI correlated well with free testosterone (T) in both men (r = 0.551, p < 0.001) and women (r = 0.454, p < 0.01). However, there was considerable variability among individual patients. Moreover, the FAI showed no association with sperm parameters in male patients, although total T and free T showed weak associations. The FAI may be a cost-effective alternative to free T measurement in the diagnosis of oligomenorrhea and hirsutism in women as previously shown, but may have little relevance in men.

Abstract
BACKGROUND Androgen excess is frequently associated with oligomenorrhea as well as acne. Oligomenorrhea in hirsute women has been demonstrated to be associated with higher active testosterone levels than found in eumenorrheic hirsute women. This study was designed to evaluate whether similar findings are present in women with acne. Forty-four consecutive women with acne were evaluated by measuring their levels of total testosterone, biologically active testosterone, and free testosterone. The women with oligomenorrhea and acne had significantly higher levels of biologically active testosterone than those with eumenorrhea and acne. This implies that biological active testosterone should be measured in oligomenorrheic women with acne and, if elevated, consideration should be given to antiandrogen therapy. METHODS Data were collected from 44 consecutive Caucasian women aged 14 to 38 years. The patients were separated into two groups based on menstrual history. Group 1 had regular menses, and group 2 had oligomenorrhea, defined as menstrual intervals of greater than 36 days. All patients had blood samples drawn on their initial office visit, regardless of the phase of the menstrual cycle, and the levels of total testosterone (TT), biologically active testosterone (BT), and free testosterone (FT) were obtained. RESULTS The serum TT level was 87 +/- 41.3 ng/dL (range, 31-150 ng/dL) in oligomenorrheic women and 56 +/- 27.5 ng/dL (range 8-107 ng/dL) in eumenorrheic women. There was no statistically significant difference. The serum BT level in oligomenorrheic women was 33 +/- 16.9 ng/dL (range, 11-51 ng/dL) and in eumenorrheic women 19 +/- 13.6 ng/dL (range, 11-51 ng/dL). This difference was statistically significant (p < 0.05). The serum FT level in oligomenorrheic women was 18 +/- 9.4 pg/mL (range, 1-29 pg/mL) and in eumenorrheic women 10 +/- 7.1 pg/mL (range, 1-32 pg/mL). This difference was not statistically significant (Table 1). CONCLUSIONS Women with acne and oligomenorrhea, similar to women with hirsutism and oligomenorrhea, have higher levels of biologically active testosterone than those with normal menses.

Abstract
The aim of this study was to determine those hormonal alterations in the gonadotropin-ovarian axis that are related to eating behavior in oligomenorrheic patients. We studied 74 oligomenorrheic women aged 26.2 +/- 0.8 years, divided into group IA (N = 13) with eating disorders, group IB (N = 61) without eating disorders and 18 normally cycling controls aged 29.2 +/- 1.6 years (group II). No subject had ovarian failure, pituitary disease, thyroid dysfunction or was taking any drug. Blood samples were taken on days 3-6 after the last menses. Luteinizing hormone (LH) was measured in two plasma pools, each made up of three samples taken at 30-min intervals, starting at 15.00 h (LH-15h) and 09.00 h (LH-9h), which allowed the mean LH (mLH) and variability in LH (V-LH: percentage increase from the lower to the higher of the two LH values) to be calculated. Follicle-stimulating hormone (FSH), sex steroids, and gonadotropin-releasing hormone-stimulated LH (sLH) and -FSH (sFSH) were also evaluated. Eating behavior was evaluated with the EAT questionnaire; the EAT 26 score, the dieting score (DS) and bulimia score (BS) were calculated. Dietary intake was evaluated in 35 group IB patients based on food diaries analyzed with the REGAL program, to evaluate daily calorie intake (Cal) and calories provided by carbohydrates (Carb), lipids (Lip) and proteins (Prot). Comparisons between groups were done by analysis of variance (followed by the Fisher PLSD test) and the Kruskal-Wallis test. Groups IA, IB and II did not differ regarding age, body mass index, LH-9h, LH-15h, mLH, FSH, sLH, sFSH, estradiol or dehydroepiandrosterone sulfate; group IA had a higher V-LH than group II (p < 0.02) and a higher testosterone level than groups IB and II (p < 0.05). Positive correlations were found between V-LH and DS (p < 0.01) and BS (p < 0.05), and between testosterone and BS (p < 0.02) and DS (p < 0.05). The V-LH was negatively correlated with Cal and Carb, and testosterone was positively correlated with Cal and Lip. In patients referred for oligomenorrhea, it is concluded that testosterone levels and variability of LH levels are related to eating behavior.

Abstract
This study is designed to evaluate the effectiveness, safety and tolerability of a low dose of purified FSH administration using a fixed protocol in oligomenorrheic patients not desiring pregnancy. We used a low dose (75 IU/day for 5 days) of purified FSH (Metrodin) in 10 oligomenorrheic patients (aged 18-30) for 25 cycles. The onset of menstruation occurred in 7 patients (70%) and in 19 treatment cycles (76%), the ovulation was verified in 5 of these patients (50%) for 13 cycles (52%). One patient had spotting after the treatment, 2 patients did not have any response. The treatment did not cause side effects and it showed a good tolerability.

Abstract
OBJECTIVE There is a paucity of longitudinal endocrine studies of infertile patients with oligomenorrhoea. We have assessed the frequency and quality of spontaneous follicular development and luteal function in patients with oligomenorrhoea and infertility (PCOS), and have related the observed criteria to circulating LH activity. DESIGN Prospective detailed investigations in a cohort of unselected patients. PATIENTS Infertile women with oligomenorrhoea (PCOS, n = 131) presenting to the infertility clinic at the Royal Infirmary, Glasgow. MEASUREMENTS Patients were monitored with frequent plasma oestradiol (E2) concentration assessments over a minimum period of 3 weeks, starting more than 2 weeks after a menstrual bleed. When follicular maturation was identified the patient provided daily blood samples through to her ensuing menstrual bleed, and E2, progesterone, total testosterone, FSH and LH were assessed in these samples. Luteal phase progesterone profiles were assessed between the days LH surge +2 and LH surge +6 by means of a progesterone index. RESULTS Forty-eight per cent of the patients showed evidence of follicular development. The oestradiol profiles in the patients showing follicular growth were normal, but the progesterone curve was sub-normal in the early luteal phase, due to a high proportion of deficient luteal phases. The mean LH concentrations were elevated in the whole group, but no difference was observed between the mean LH values for those patients showing spontaneous follicular development and those who did not, and the incidence of ovulation was similar in the normal LH and elevated LH groups. Similarly, no relation was established between LH and the quantitative assessment of luteal phase progesterone profiles (progesterone index), and the distribution of progesterone indices was similar in the normal LH and elevated LH groups. Testosterone concentrations were positively correlated with LH (p = 0.008) but not with the incidence of spontaneous follicular growth. There was no significant difference in the incidence of spontaneous ovulation between the patients with elevated or normal mean follicular phase testosterone concentrations. CONCLUSION The data indicate that both LH and testosterone secretion in PCOS were closely linked, but that neither was directly linked to the incidence or inhibition of spontaneous follicular development in PCOS, or to the disturbance in luteal phase progesterone profiles.

Abstract
OBJECTIVE To examine the serum total renin in women with polycystic ovarian syndrome (PCOS) and in controls. SETTING Outpatient clinic of reproductive endocrinology at Turku University Central Hospital, Turku, Finland. PATIENTS Forty-four oligomenorrheic women with PCOS (body mass index [BMI] 18.0 to 49.0 kg/m2) and 25 control women with regular menstrual cycles (BMI 18.0 to 53.5 kg/m2). MAIN OUTCOME MEASURES The concentrations of total renin, LH, FSH, T, androstenedione (A), sex hormone-binding globulin (SHBG), and insulin in serum. RESULTS The concentration of total renin in serum was higher in PCOS women than in healthy women independently of BMI, age, or serum insulin. The serum total renin measurement discriminated PCOS patients and control women to a similar extent as the previously used hormonal parameters (LH:FSH, T, A, and T:SHBG) as judged by receiver-operating characteristic analysis. Positive correlations were found between the serum total renin level and LH concentration, LH:FSH ratio, T and A levels, and T:SHBG ratio. Analysis of serum total renin in PCOS patients during oligomenorrhea and after menstruation did not reveal any significant changes. CONCLUSIONS The elevated concentration of serum total renin suggests an enhanced activity of ovarian renin-angiotensin system in PCOS. The determination of serum total renin may provide a novel tool in the diagnostics of PCOS, because its serum level is elevated in PCOS women independently of BMI and serum insulin.
