Abstract
BACKGROUND The hypothalamic-pituitary-gonadal axis is transiently activated during the postnatal months in boys, a phenomenon termed "minipuberty" of infancy, when serum testosterone (T) increases to pubertal levels. Despite high circulating T there are no signs of virilization. We hypothesize that free T as measured in saliva is low, which would explain the absence of virilization. METHODS We measured serum total T and free T in saliva using liquid chromatography-tandem mass spectrometry (LC-MS/MS) in 30 infant boys, aged 1-6 months, and in 12 adolescents, aged 11-17 years. RESULTS Total serum T in all infants was, as expected, high (172 ± 78 ng/dL) while salivary T was low (7.7 ± 4 pg/mL or 0.45 ± 0.20%). In contrast, salivary T in the adolescents was much higher (41 ± 18 pg/mL or 1.3 ± 0.36%) in relation to their total serum T (323 ± 117 ng/dL). We provide for the first time reference data for salivary T in infants. CONCLUSION Measurement of salivary T by LC-MS/MS is a promising noninvasive technique to reflect free T in infants. The low free T explains the absence of virilization. The minipuberty of infancy is more likely of intragonadal than peripheral significance.

Abstract
PURPOSE Systemic lupus erythematosus (SLE) is an autoimmune disorder and may affect the reproductive health status of the women. Objective is to analyze the types, incidence of various menstrual disturbances in these women, to identify risk factors and to assess the gonadal function. METHODS The prospective cohort study was conducted in the SLE clinic of the Rheumatology Department of IPGMEandR, Kolkata from April 2010 to April 2011. Out of 152 females attending clinic, 110 patients fulfilling criteria were included in the study. RESULTS Mean age of the study population was 27.25±3.4 years. Sixty six cases had menstrual abnormalities (12.72% amenorrhea, 44.45% oligomenorrhea, 2.7% premature ovarian failure, 10.9% menorrhogia). When comparative analysis of demographic, hormonal, ovarian Doppler and therapeutic variables of normal and abnormal cycles was carried out, following parameters were significantly more related to patients with abnormal cycle ; SLEDAI score (12.48±5.53 vs 8.69±4.9; p=0.00), disease duration (6.46±3.08 vs 4.3±1.36; p< 0.05), TSH (7.73±8.64 vs 3.07±2.06; p=0.00.), LH (6.55±4.38 vs 4.56±3.29; p=0.02), a high normal prolactin (12.57±7.75 vs 8.73±3.07; p=0.02), peak systolic velocity (6.53±2.17 vs 9.12±2.1; p=0.00), end-diastolic volume (4.21±2.9 vs 9.35±2.32; p=0.00) and cumulative dose of steroid (24.02±41.44 vs 9.32±9.96; p=0.01).Cyclophosphamide with cumulative dose ≥10 gm was related to amenorrhea and affected gonadal function. Gonadal insufficiency was evident in 33.63% and 2.72% had ovarian failure. CONCLUSIONS Reduced menstruation is a major health concern in women with SLE as it is frequent and can result in depressed and failed gonadal function later. Doppler study of ovaries is a novel way of depiction of gonadal status in these women. Certain risk factors and revolving treatment part can be preventable.

Abstract
STUDY QUESTION What is the optimal protocol of management for phenotypic female patients with Y chromosome or Y-derived sequences, in particular for adult patients? SUMMARY ANSWER Immediate gonadectomy, long-term hormone therapy and psychological care are suggested to be the optimal management for older phenotypic female patients with Y chromosome or Y-derived sequences. WHAT IS KNOWN ALREADY Phenotypic female patients with Y chromosome or Y-derived sequences are at increasing risk of developing gonadal tumors with age. Early diagnosis and safe guidelines of management for these patients are needed. STUDY DESIGN, SIZE, DURATION One hundred and two phenotypic women with Y chromosome or Y-derived sequences were included in a straightforward, retrospective-observational study conducted over a period of 26 years from January 1985 to November 2010. PARTICIPANTS/MATERIALS, SETTING AND METHODS Patients aged 16-34 years presenting to our Academic Department of Gynecology with symptoms of disorders of sex development were subjected to history taking, hormonal evaluation, conventional cytogenetic analysis, PCR, histopathology and immunohistochemistry. Features of the gonads were examined and the outcome of prophylactic gonadectomy evaluated. MAIN RESULTS AND THE ROLE OF CHANCE Among the patients recruited in our study, 48 patients (47.1%) were diagnosed with complete/partial androgen insensitivity syndrome (CAIS/PAIS) (46XY), 33 cases (32.4%) with gonadal dysgenesis (46XY) and the remaining subjects (20.1%) with mixed gonadal dysgenesis (with sex chromosome structural abnormalities). The total incidence of malignancy was 17.6%. Seventeen patients (16.7%) had gonadoblastoma, while one patient (1.0%) with gonadal dysgenesis had dysgerminoma. Gonadoblastoma were observed in 2/21 patients with sex chromosome structural abnormalities (9.5%), 3/33 patients with gonadal dysgenesis (9.1%), 9/30 patients with CAIS (30.0%) and 3/18 patients with PAIS (16.7%). LIMITATIONS, REASONS FOR CAUTION Selection bias in this cohort study may affect data interpretation due to the low incidence of disorders of sex development in the general population. WIDER IMPLICATIONS OF THE FINDINGS The risk for malignant transformation may occur in early life and highly increase with age in patients with Y chromosome or Y-derived sequences. Optimal timing of gonadectomy should be decided by multiple factors including the subgroup of disorder, age and degree of patient's maturity. In addition, gonadal biopsy is suggested when the disease is diagnosed and any evidence of premalignancy warranties gonadectomy.

Abstract
Adolescent gynecology is an important part of clinical care of adolescent females. This discussion provides a basic review of current issues in adolescent gynecology, including consideration of current pubertal concepts with attention also given to delayed and precocious puberty. Causes of breast masses are reviewed, including discussion of the ANDI classification. It is recommended that physicians provide sexuality education to their adolescent patients, in addition to the community, to reduce the high rates of unintended adolescent pregnancy and STIs in teens that continue in the United States. Finally, attention is provided to ovarian masses and their management. Adolescent medicine physicians may have to work with a variety of specialists in their care of adolescents and the many gynecologic conditions that may arise.

Abstract
More than half of all people with cancer are treated with radiation therapy. Over the last decade the technical advances, both in therapy beam precision and imaging, have greatly improved the therapeutic ratio and accuracy of modern radiotherapy. However, damaging healthy tissues near the tumor leads to radiation induced injury that develops immediately and continue to progress long after exposure to radiation. Recently dramatic advances have been made in understanding the determinant of tissue response to radiation exposure.

Abstract
BACKGROUND Infertility is one of the most prevalent health disorders in young adults. OBJECTIVES To study the distribution of causes of infertility in couples referred to primary infertility clinics in Israel. METHODS Data for a 9 year period were derived from two clinics of major women's hospitals run by the country's largest health insurance fund. All patients were treated by one physician. Laparoscopy was not performed to rule out endometriosis. RESULTS Of the 2515 couples identified, 1991 (79.2%) had a definitive diagnosis following complete workup (including hysterosalpingography). Mean age was 29.6 +/- 6.0 years; mean duration of infertility was 1.7 +/- 1.8 years. Primary infertility accounted for 65% of cases. Causes of infertility were male factor (45%), oligo-ovulation disorders (37%), and tubal damage (18%). Infertility factors were identified in the woman alone in 30.6% of cases and the man alone in 29.2%. Two combined infertility factors were found in 18% of patients, and three combined factors in 0.5%. The rate of unexplained infertility (which probably includes non-tubal endometriosis) was 20.7%. CONCLUSIONS As male factor accounts for almost half of all cases of infertility in couples, sperm analysis is mandatory before any treatment.

Abstract
To establish the optimal age of sexual maturation in Egyptian children, Tanner's maturity stages were determined for a sample of children and adolescents (1550 girls, 1563 boys) ranging from 6.5 to 18.5 years. The mean age for attainment of pubic hair (stage PH2) was 10.46 (SD 1.36) years for girls and 11.86 (SD 1.45) years for boys. For axillary hair (stage A2), mean age was 11.65 (SD 1.62) years for girls and 13.55 (SD 1.52) years for boys. The mean age at menarche in girls was 12.44 years and for breast development (stage B2) was 10.71 (SD 1.30) years. Testicular volume by palpation showed that the mean age of genital stage G2 for boys was 10.56 (SD 1.40) years. The study results can aid in the assessment of sexual maturation and pubertal disorders in Egyptian adolescents.

Abstract
Inhibin B is a gonadal dimeric peptide, produced in men in testicular Sertolli cells. Inhibin B blood level knowledge can be a useful tool in the management of difficult diagnostic problems, such as ambiguous genitalia, the distinction between cryptorchidism and anorchidism and the hypogonadotrophic hypogonadism/delayed puberty differential diagnosis. Inhibin B measurements can help in gonadal dysgenesis evaluation, androgen insensitivity management and also in the diagnosis of some gonadal tumors. In adult men, inhibin B evaluation is helpful in the investigation of male infertility, especially in the judgment of the prognosis of testicular biopsy in in-vitro fertilization programs. Although commercial kits for inhibin B measurement are available at present, its evaluation is accessible in the Czech Republic for the time being in only very limited number of laboratory centers.

Abstract
PURPOSE Complete treatment for Hodgkin's lymphoma (HL) may disturb functioning of different organs leading to deteriorated quality of future life. Endocrine complications are one of the most common and may be the result of radiotherapy of neck, mediastinal and infradiaphragmatic regions, as well as chemotherapy, especially with alkylating agents. The aim of our study was to analyse gonadal and thyroid disturbances in young adults after the treatment for HL in childhood. MATERIAL AND METHOD In 36 adolescents and young adults (19 males; mean age 20.5+/-3.1) 5.9+/-3.4 years after treatment for HL, we have examined the thyroid function (TSH, thyroxine-T4, tri-iodothyronine-T3, ultrasound) as well as gonadal function in males: FSH, LH, testosterone, inhibin B and in females: FSH,LH, estradiol, inhibin B and anti-müllerian hormone (AMH). Radiotherapy of supradiaphragmatic region was used in 34/36 patients and for infradiaphragmatic region in 17 patients (7 males). Chemotherapy was composed of B-DOPA and MVPP protocols. RESULTS 1. Signs of subclinical hypothyroidism (elevated TSH) were found in three survivors (irradiated on upper mediastinum). Ultrasonic abnormalities (simple nodules) were found in three patients after mantle radiotherapy. 2. In males the mean values of FSH were higher than in healthy boys (16.0 mIU/ml+/-13.0 vs 3.9 mIU/ml+/-2.0) p=0.0004, inhibin B- lower (50.1 ng/L +/- 43.5 vs.68.1 ng/L +/- 77.2) p = 0.0001, and testicular volume lower (17,3 ml+/-3.8 vs 18.5 ml+/-4.8) p = 0.05. The mean values of LH and testosterone were normal. Inhibin B<2SD and FSH>2SD in 6/19 males, LH>2SD in 4 cases (irradiated infradiaphragmatically) were found. 3. In females, we observed higher FSH values (8.53 mIU/ml+/-3.25 vs 5.8 mIU/ml+/-2.03) p=0.045; lower AMH (17.19 pmol/L+/-14.84 vs 29.40 pmol/L+/-13.2) p=0.05 and tendency to lower inhibin B (31.47 ng/L+/-18.83 vs 47.9 ng/L+/-26.39) p=0.08 than in control group. LH and estradiol concentrations did not differ in between groups. FSH>2SD, inhibin B and AMH<2SD were found in 5 girls (infradiaphragmatic irradiations in 4 cases). CONCLUSIONS Our observations show the possibility of different endocrine disturbances after combined treatment for HL, especially gonadal function disturbances. Considering these long-term complications, further follow-up is needed, even in the absence of clinical symptoms.

Abstract
Cytotoxic chemotherapy and radiotherapy have improved the survival rates in many malignant conditions, particularly in paediatric patients with haematologic malignancies. Treatment is associated with significant morbidity in many patients, and alterations in gonadal function are among the most common long-term side effects of therapy. Chemotherapy and radiotherapy may damage germ-cell spermatogonia, resulting in impaired spermatogenesis or sterility in the male. This review describes gonadal dysfunction in males at risk of chemotherapy and radiotherapy and the type of malignancy in childhood induced infertility. The detection and diagnostic methods of gonadal damage in males after treatment for a childhood malignancy are also described and therapeutic strategies for preventing these problems are outlined.

Abstract
We report the cases of 3 patients with brucellar gonadal abscess who were examined with gray-scale and color Doppler sonography. In these 3 cases, sonography revealed a thick-walled avarian (n = 2) or testicular (n = 1) abscess. Duplex Doppler sonography indicated a low-resistance type of flow in all 3 patients. The diagnosis of brucellar gonadal abscess is difficult, because it may have a misleading tumor-like appearance. Awareness of the imaging findings of gonadal abscess in patients with brucellosis and correlation with the results of serologic testing can allow early diagnosis, especially in endemic areas.

Abstract
Anti-Müllerian hormone (AMH), also called MUllerian inhibiting substance (MIS) is a product of supporting gonadal Sertoli and granulosa cells. Its main physiological role is the induction of regression of Müllerian ducts in male fetuses but it also plays a role in Leydig cell steroidogenesis and in follicular development. It is a member of the transforming growth factor B family and signals through two serine/threonine kinase receptors, only one of whom, type II, is specific. Type I receptors and the intracytoplasmic signaling molecules are shared with the bone morphogenetic family. AMH is positively regulated by SF1, SOX9 and FSH. Testosterone is a powerful downregulator. Males lacking functional AMH or AMH receptor genes do not undergo regression of MUllerian derivatives during fetal life. AMH is an excellent marker of prepubertal testicular function and has gained recognition as a valuable marker of follicular reserve in adult women.

Abstract
We present a male patient with photosensitivity since the earliest months of his life, and pigmented macules in exposed areas, some showing clinical atypia, which increased in number over time. Molecular biology studies detected an alteration in DNA repair ability, so xeroderma pigmentosum was diagnosed. Shortly after birth, low weight, microcephaly and psychomotor retardation had been observed, but the cause was not established. The patient progressively showed neurological disorders that included perceptive deafness, hyporeflexia and areflexia, as well as choreoathetotic movements. Therefore, we felt that the patient's symptoms fit De Sanctis-Cacchione syndrome.

Abstract
The polycystic ovary syndrome (PCOS) in women belongs to the most frequent endocrinopathies. This syndrome is characteristic by a hormonal and metabolic imbalance. It seems to be a kind of an oligogenic disease resulting from the interaction among several key genes and environmental effects. Considering the genetic basis of this syndrome there is no reason why the syndrome could not occur in men as well, be it with a different symptomatic expression. Premature baldness before the age of thirty used to be suggested as a symptom of the male PCOS equivalent. Yet there still seems to be rather a meagre attention devoted to the endocrinological changes in men in the specialised literature, although there do exist genealogical studies on the occurrence of alopecia or glucose metabolic disorder in male members of the families where a considerable number of females were affected by PCOS.

Abstract
A biomarker can be broadly defined as any biological index capable of being measured, which is associated with or indicative of a defined biological endpoint such as a developmental or disease stage. Identification and verification of anatomical, endocrine, cellular and molecular biomarkers is crucial for successful clinical diagnosis and treatment of toxicity and disease, as well as basic toxicological, epidemiological and other research. Various biomarkers of reproductive development and health have been identified, including those associated with pubertal development, adult reproductive health and pregnancy outcome. Herein we discuss those in situ biomarkers which have been more closely associated with toxicant action on the reproductive system. Biomarkers of toxicant exposure and susceptibility are addressed, but the majority of the review focuses on those biomarkers which may prove useful for determining current pathophysiological status or predicting future adverse outcomes. In males these are primarily associated with altered spermatogenesis and sperm parameters, and in females with altered endocrine function. We conclude that although few robust in situ biomarkers are currently available which are specific for toxicant exposure, susceptibility or effect in reproductive systems, there is expectation that post-genomic technologies offer a new paradigm for identifying and verifying such biomarkers as may exist.

Abstract
Diagnostic evaluation of patients with an abnormal gonad is complex because of multifactoral etio-pathogenesis and rarity of the conditions. In the text to follow, we have briefly discussed the embryology and attempted to classify abnormal gonadal disorders. The aims of evaluating such a child are to: (1) establish genetic sex; (2) determine the hormonal milieu; (3) evaluate the anatomy of internal and external genitalia and gonads; and (4) in older children, assess the phenotypic and psychological sex. In newborn children with ambiguous genitalia, the focus is now on accurate gender assignment. A team approach is needed and decisions are based on likely prognosis for behavior and gender orientation. The recent advances in cytogenetics have proven to be helpful in early and accurate diagnosis. In patients with an abnormal gonad, four conditions can present with sexual ambiguity at birth: female pseudohermaphroditism (or "virilized female"), true hermaphroditism, male pseudohermaphroditism (or "undervirilized male") and mixed gonadal dysgenesis. The role of clinical history and examination is emphasized in differential diagnosis and management. Timing of surgery for each of the conditions is discussed.

Abstract
Anti-Mullerian hormone (AMH) is a gonadal hormone synthesized by granulose cells of the ovary and Sertoli cells of the testis. Anti-Mullerian hormone is used to facilitate the evaluation of intersex disorders and as a marker in some ovarian tumors or ovarian reserve assessment in the infertility cases. Serum levels of AMH hold objective information, which is useful in the clinical practice. Therefore it is necessary to decimate the normal and the abnormal levels of AMH.

Abstract
Management of iatrogenic gonadal reproductive failure and sexual morbidity assumes a priority, especially in young recipients of high-dose chemotherapy and stem cell transplantation (SCT). Hormone replacement treatment (HRT) is beneficial for correction of sexual symptoms and osteoporosis in both sexes, especially in females. Sperm banking is the standard technique for preservation of fertility in adult and sexually mature adolescent males. Testicular tissue cryopreservation has a place in well-selected azoospermic adults and in mentally and sexually competent adolescents. In vitro fertilisation using superovulation with embryo-cryopreservation (for future embryo transfer) is the most tried method in female SCT recipients with good results. In mentally and sexually competent adolescents and adults without a partner, ovarian cortical tissue cryopreservation has a place for subsequent re-implantation to orthotopic or heterotopic sites. Gonadotrophin releasing hormone (GnRH) co-treatment during chemotherapy, is a promising method for the future. Although generally reassuring, continued monitoring of the offspring of SCT survivors and follow-up of all recipients of SCT is important for return of spontaneous or induced fertility.

Abstract
The problems associated with hyperandrogenism are not uncommon in primary care settings. In fact, polycystic ovary syndrome, a common cause of androgen excess, exists in 5% to 10% of women during their reproductive years, with onset typically in adolescence. The subject of this column is the AACE's Hyperandrogenism Guidelines, which review the evaluation and treatment of the disorders causing androgenic excess.

Abstract
INTRODUCTION The effects of an intensive training programme involving screening of children for disorders of growth and puberty for community based nursing and medical staff employed by Cardiff Community Healthcare NHS Trust were audited to assess the impact of this training on referrals to the local hospital based growth clinic. METHOD Referrals from community based staff to the growth clinic of patients living in the geographical area in which staff underwent training were compared with those from general practitioners in the 18 months prior to and following the training programme. Hospital notes were available for 209 of 254 (82.2%) patients identified. We excluded 112 referrals as they did not have a problem relating to growth or puberty or were inter-hospital referrals. Hence 97 referrals were included in the final audit. RESULTS Forty referrals occurred prior to compared with 57 following the training programme. The number of referrals from community based staff increased threefold during the six months immediately following the training programme but then returned to the previous level. There were no differences in age or height standard deviation scores at referral between groups at any time. The proportion of children referred from the community with significant abnormalities of growth or puberty (for example, hypothyroidism or precocious puberty) increased from two of 15 referrals to six of 30 referrals following the training programme. CONCLUSIONS Intensive training in screening for disorders of growth and puberty can increase the number of referrals of children with significant pathology but at the cost of increased total number of referrals. The increase in referrals is not sustained with time, suggesting continued training is necessary.

Abstract
Function of hypothalamic-pituitary-ovarian axis is an essential factor for the maintenance of regular cycles in mature women. The disturbance of function of those organs causes gonadal dysfunction such as anovulation, amenorrhea and menstrual disorders. Therefore, the correct diagnosis for the assessment of CNS and ovarian function is clinically important to treat the patients those who have an menstrual disorders. In this review, the mechanism of normal gonadal cycles and the diagnostic method and the treatment of gonadal dysfunction are described.
