Polycystic Ovary Syndrome Phenotype D Versus Functional Hypothalamic Amenorrhea With Polycystic Ovarian Morphology: A Retrospective Study About a Frequent Differential Diagnosis

GnRH ability to release FSH and LH in women with functional hypothalamic amenorrhea: a retrospective cohort study about women with and without polycystic ovarian morphology

Nearly 50% of women with functional hypothalamic amenorrhea (FHA) reveal polycystic ovarian morphology (PCOM), a known risk factor for ovarian hyperstimulation syndrome. However, gonadotropin releasing hormone-agonist (GnRH-a) triggers are not recommended in FHA, since an inadequate endogenous surge in luteinizing hormone (LH) is expected. We aimed to challenge this concept and evaluated LH levels after GnRH stimulation in FHA-women with and without PCOM. In a retrospective cohort study, 82 women with FHA, who underwent a GnRH stimulation test, were included. Thirty-five women revealed PCOM (42.7%). Twenty minutes after GnRH stimulation, there was an increase of serum LH levels in FHA-PCOM (median basal: 2.7 mIU/mL, IQR 1.1-4.6 versus median stimulated: 13.5 mIU/mL, IQR 7.8-21.6, p < 0.001) and in FHA-nonPCOM patients (median basal: 2.5 mIU/mL, IQR 0.5-3.9 versus median stimulated: 5.7 mIU/mL, IQR 2.4-13.9, p < 0.001). Overall, positive correlations (p < 0.001) were found between basal and stimulated LH levels. In FHA-PCOM patients, 42.9% of patients revealed stimulated LH levels >15 mIU/mL, while this was the case in 19.1% of FHA-nonPCOM patients (p = 0.034). In women with FHA-PCOM, ovulation induction with a GnRH-a trigger might be feasible. Future research should focus on the prediction of an adequate response to GnRH triggers in the IVF setting.

Should anti-Müllerian hormone be a diagnosis criterion for polycystic ovary syndrome? An in-depth review of pros and cons

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology (PCOM). Despite the widespread use of the Rotterdam criteria, challenges in diagnostic accuracy persist. Anti-Müllerian hormone (AMH), a glycoprotein secreted by ovarian follicles, has emerged as a promising biomarker for refining diagnosis due to its strong correlation with follicular count and elevated levels in women with PCOS. This review critically evaluates the advantages and limitations of incorporating AMH into PCOS diagnostic criteria. Elevated AMH levels are indicative of PCOM and anovulation, offering a non-invasive diagnostic tool that minimizes interobserver variability in ultrasound-based assessments. Additionally, AMH remains stable throughout the menstrual cycle and aligns with phenotypic diversity in PCOS, potentially supporting individualized management strategies. However, significant challenges remain. Variability in AMH assay methods, the absence of comparable cut-off values, and influences of age, ethnicity, and obesity on AMH levels limit its universal applicability. Additionally, AMH cut-offs for PCOS diagnosis, ranging from 3.5 to 5 ng/mL, raises questions about its clinical relevance, as there is not clear evidence of its biological significance. The review also highlights AMH's clinical utility in reproductive medicine, particularly in predicting ovarian response to stimulation, tailoring gonadotropin dosages, and optimizing assisted reproductive technology outcomes. While AMH holds promise as a complementary diagnostic criterion for PCOS, its fully integration into clinical practice requires further validation through standardized assays, population-specific cut-offs, and robust studies to address existing limitations. In conclusion, AMH harbours the potential to enhance the specificity and sensitivity of PCOS diagnosis, particularly in dubious cases. However, the inclusion of AMH in the current criteria for diagnosing PCOS still requires addressing methodological challenges and balancing its benefits against inherent limitations.

Evaluating the diagnostic accuracy of androgen measurement in polycystic ovary syndrome: a systematic review and diagnostic meta-analysis to inform evidence-based guidelines

BACKGROUND

Biochemical hyperandrogenism is a hallmark and diagnostic feature of polycystic ovary syndrome (PCOS). However, the most accurate androgen measurement for assessing biochemical hyperandrogenism in PCOS diagnosis remains uncertain.

OBJECTIVE AND RATIONALE

This systematic review aimed to assess different androgen measures [including total testosterone (TT), calculated free testosterone (cFT), free androgen index (FAI), androstenedione (A4), dehydroepiandrosterone sulfate (DHEAS), and dihydrotestosterone (DHT)] for accuracy in diagnosing biochemical hyperandrogenism in women with PCOS, to inform the 2023 International PCOS Evidence-based Guidelines.

SEARCH METHODS

To update evidence from the 2018 International PCOS Guidelines, a systematic search from 3 July 2017 to 23 June 2023 was conducted across Medline (Ovid), CINAHL, all EBM, EMBASE, and PsycInfo for articles evaluating androgens in the diagnosis of biochemical hyperandrogenism. The revised Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) was used to assess the risk of bias and applicability. A diagnostic test accuracy meta-analysis was performed using STATA 18 software. Summary sensitivity and specificity were calculated with 95% CIs using the bivariate model, while the hierarchical summary receiver operating characteristics (ROC) model was used to produce a summary ROC curve.

OUTCOMES

Of 23 studies reviewed, 18 were included in the meta-analysis, with data from 2857 participants (1650 with PCOS and 1207 controls). For diagnosing biochemical hyperandrogenism in PCOS, the pooled sensitivity, specificity, and AUC with 95% CI were for TT: 0.74 (0.63-0.82), 0.86 (0.77-0.91), and 0.87 (0.84-0.90); cFT: 0.89 (0.69-0.96), 0.83 (0.79-0.86), and 0.85 (0.81-0.88); FAI: 0.78 (0.70-0.83), 0.85 (0.76-0.90), and 0.87 (0.84-0.90); A4: 0.75 (0.60-0.86), 0.71 (0.51-0.85), and 0.80 (0.76-0.83); and DHEAS: 0.75 (0.61-0.85), 0.67 (0.48-0.81), and 0.77 (0.73-0.81), respectively. In subgroup analyses, liquid chromatography with tandem mass spectrometry (LC-MS/MS) had superior sensitivity for measuring cFT, FAI, A4, and DHEAS, and superior specificity for measuring TT, cFT, and FAI, compared to the direct immunoassay method.

WIDER IMPLICATIONS

Our results directly informed the 2023 International PCOS Guideline recommendations to use TT and FT as the first-line laboratory tests to assess biochemical hyperandrogenism in the diagnosis of PCOS. cFT should be assessed by equilibrium dialysis or ammonium sulfate precipitation, or calculated using FAI. If TT or cFT are not elevated, A4 and DHEAS could also be considered, noting their poorer specificity. Laboratories should utilize LC-MS/MS for androgen measurement given its high accuracy. Future studies should focus on establishing optimal normative cut-off values in large, unselected, and ethnically diverse cohorts of women.

Functional hypothalamic amenorrhoea and polycystic ovarian morphology: a narrative review about an intriguing association

BACKGROUND

Functional hypothalamic amenorrhoea (FHA) is responsible for 20-35% of all cases of secondary amenorrhoea and, thus, is the second most common cause of secondary amenorrhoea after polycystic ovary syndrome (PCOS). A high number of patients with FHA reveal polycystic ovarian morphology (PCOM) on ultrasound. The combination of amenorrhoea and PCOM can lead to confusion. First, amenorrhoeic women with PCOM fulfil the revised Rotterdam criteria and, thus, can easily be misdiagnosed with PCOS. Moreover, it has been claimed that some women with FHA and concomitant PCOM differ from those without PCOM in terms of endocrine regulation and metabolic traits.

OBJECTIVE AND RATIONALE

The main focus of this article was on studies about FHA, which differentiated between patients with or without PCOM. The aim was to estimate the prevalence of PCOM and to look if it has an impact on pathophysiologic, diagnostic and therapeutic issues as well as on long-term consequences.

SEARCH METHODS

Peer review original and review articles were selected from PubMed searches for this review. Searches were performed using the search terms 'polycystic AND functional hypothalamic amenorrhoea'. The reference lists of publications found were searched for relevant additional studies. The inclusion criteria for publications were: English language, patients' age ≥ 18 years, year of publication >1980, original studies, validated diagnosis of FHA, and validated diagnosis of PCOM using transvaginal ultrasound.

OUTCOMES

The prevalence of PCOM in women with FHA varied from 41.9% to 46.7%, which is higher than in healthy non-PCOS controls. Hypothetically, the high prevalence might be due to a mixture of silent PCOM, as in the general population, and pre-existing PCOS. Several differences in metabolic and hormonal parameters were found between FHA-PCOM and FHA-non-PCOM patients. While oestrogen deficiency is common to both groups of patients, FHA-PCOM patients have a higher BMI, higher levels of anti-Müllerian hormone (AMH) and testosterone, a higher increase in LH in the course of a GnRH test, and lower sex hormone binding globulin (SHBG) levels than FHA-non-PCOM patients. The differential diagnosis between FHA-PCOM and PCOS, especially PCOS phenotype D (PCOM and oligo-/anovulation without hyperandrogenism), can be challenging. Several parameters have been suggested, which are helpful though not absolutely reliable. They include the typical causes for FHA (excessive exercise, energy deficit, and/or psychological stress), the serum levels of LH, testosterone, and SHBG, as well as the progestin challenge test. Whether FHA-PCOM has a different risk profile for long-term consequences concerning patients' metabolic and cardiovascular situation as well as their bone mass, is unclear. Concerning therapeutic aspects, there are only few data about FHA-PCOM compared to FHA-non-PCOM. To treat anovulation, the use of pulsatile GnRH treatment seems to be equally effective in both groups. Similar to FHA-non-PCOM patients, pulsatile GnRH therapy would be more efficient than exogenous gonadotropins in FHA-PCOM patients.

WIDER IMPLICATIONS

Women with FHA-PCOM present a special sub-population of FHA patients. The diagnostic pitfall of FHA-PCOM should be emphasized in clinical guidelines about FHA and PCOS. The fact that almost half of the women with FHA have an ovarian follicle excess (i.e. PCOM) in face of low gonadotropin serum levels suggests that the intra-ovarian regulation of folliculogenesis is subject to individual variations, for unknown reasons, either genetic or epigenetic. Further studies are needed to investigate this hypothesis.

[Difficulties of differential diagnosis of functional hypothalamic amenorrhea and polycystic ovary syndrome: a systematic review]

BACKGROUND

Functional hypothalamic amenorrhea (FHA) and polycystic ovary syndrome (PCOS) are pathologies most common in women of reproductive age. Menstrual irregularities (oligo/amenorrhea) are the most common symptom of these diseases. FHA develops against the background of stress or excessive physical exertion, and is characterized by inhibition of neuroendocrine regulation of the hypothalamic-pituitary-ovarian axis with a subsequent decrease in the production of sex steroids. For PCOS, the most important pathogenetic links are insulin resistance and hyperandrogenism. The pathology of neuroendocrine regulation in ovarian hyperandrogenism is accompanied by excessive pulsatile secretion of gonadotropin-releasing hormone (GnRH), promoting increased production of luteinizing hormone (LH). Both FHA and PCOS lead to multiple complications from other organs and systems: cardiovascular pathology, decreased bone mineral density with prolonged amenorrhea and contribute to the development of infertility.

OBJECTIVE

To analyze the works studying the problems of differential diagnosis of FHA and PCOS.

METHODS

Using PubMed, eLibrary, CyberLeninka.ru, a systematic search was conducted for articles published over the past 6 years that met the following criteria: the research that describe methods and develop criteria for the differential diagnosis of FHA and PCOS. Selected impactive publications within 1998-2018 were also included in the review.

RESULTS

This review highlights the differential diagnostic criteria for FHA and PCOS. The features of clinical, laboratory and instrumental studies are also described. Publications describing the coexistence of these pathologies in women are analyzed, and methods that allow differentiating these nosologies are described in detail.

CONCLUSION

A correct and timely diagnosis facilitates the prescription of appropriate treatment regimens, reduces the incidence of complications and improves the quality of life of women. In light of recent advances in the description of the mechanisms of neuroendocrine regulation of the reproductive system, it is necessary to further conduct research to study the role of neuropeptides in the development of FHA and PCOS, which may serve to create more accurate diagnostic markers of diseases.

Kisspeptin in functional hypothalamic amenorrhea: Pathophysiology and therapeutic potential

Functional hypothalamic amenorrhea (FHA) is one of the most common causes of secondary amenorrhea, resulting in anovulation and infertility, and is a low estrogen state that increases the risk of cardiovascular disease and impairs bone health. FHA is characterized by acquired suppression of physiological pulsatile gonadotropin-releasing hormone (GnRH) release by the hypothalamus in the absence of an identifiable structural cause, resulting in a functional hypogonadotropic hypogonadism. FHA results from either decreased energy intake and/or excessive exercise, leading to low energy availability and weight loss-often in combination with psychological stress on top of a background of genetic susceptibility. The hypothalamic neuropeptide kisspeptin is a key component of the GnRH pulse generator, tightly regulating pulsatile GnRH secretion and the downstream reproductive axis. Here, we review the physiological regulation of pulsatile GnRH secretion by hypothalamic kisspeptin neurons and how their activity is modulated by signals of energy status to affect reproductive function. We explore endocrine factors contributing to the suppression of GnRH pulsatility in the pathophysiology of FHA and how hypothalamic kisspeptin neurons likely represent a final common pathway through which these factors affect GnRH pulse generation. Finally, we discuss the therapeutic potential of kisspeptin as a novel treatment for women with FHA.

Incidence and Causes of Tubal Occlusion in Infertility: A Retrospective Cohort Study

Background and Objectives: Fallopian tubal pathology is a primary risk factor for female infertility, with simple proximal disease and proximal disease extending more distally being more common than pure distal occlusion. Proximal tubal occlusion is often attributed to ascending events, such as pelvic inflammatory disease. Conversely, while distal occlusion can also be attributable to ascending pelvic inflammatory disease, it can also have a pelvic origin, such as through endometriosis and ruptured appendicitis. The aim of this study was to identify certain causes of infertility and their association with tubal occlusion. The focus was on the location of tubal occlusion, uni- versus bilateral occlusion, and other causes of infertility, including male factors. Methods: In a retrospective study cohort study, 373 women aged between 18 and 40 years, treated from 1 January 2017 to 31 December 2022, were included. Fallopian tube patency was tested using either hysterosalpingography, hysterosalpingo-contrast sonography, or laparoscopic chromopertubation. Results: In total, 95 of 373 women (25.5%) revealed at least one occluded tube, with unilateral occlusion being more common than bilateral occlusion (60/95, 63.2% vs. 35/95, 36.8%). The majority of tubal occlusions occurred proximally (86.2%). According to the adjusted multivariate regression models, the presence of hydrosalpinx (odds ratio, OR, 13.323, 95% confidence interval, CI: 2.679-66.253, p = 0.002), myomas (OR 2.108, 95%CI: 1.008-4.409; p = 0.048), and an abnormal sperm test result of the male partner (OR 2.105, 95%CI: 1.156-3.833; p = 0.015) were statistically significant associated factors for tubal occlusion. Conclusions: Fallopian tube patency testing is still of major relevance in fertility evaluation. The presence of uterine myomas, hydrosalpinges, and a male factor significantly increase the risk.

Premature ovarian insufficiency and autoimmune profiles: a prospective case-control study

OBJECTIVE

Autoimmunity seems to be present in a large proportion of women with spontaneous premature ovarian insufficiency (POI). Whether these women are at increased risk for autoimmune disease has not been determined to date. Therefore, the aim of this study was to investigate a large series of antibodies in order to shed more light into the autoimmune risk of POI women.

METHODS

In a prospective case-control study, blood samples from 66 patients with spontaneous POI and 66 healthy controls were analyzed for a series of autoimmune antibodies.

RESULTS

POI women revealed significantly increased thyroglobulin antibodies (TGAb) (p = 0.045) and thyroid peroxidase antibodies (TPOAb) (p = 0.002). At least one abnormal autoimmune parameter was present in 37.9% of POI women, compared to 18.2% in healthy controls (p = 0.045). A strong association between POI and increased TGAb (adjusted odds ratio 3.586, p = 0.028), increased TPOAb (adjusted odds ratio 7.496, p = 0.003) and any increased autoimmune parameter (adjusted odds ratio 3.189, p = 0.008) could be demonstrated in a binary logistic regression model.

CONCLUSION

A high prevalence of autoimmunity in POI women compared to a healthy young collective could be demonstrated. Thyroid antibodies were significantly increased in POI women. Our data highlight the increased risk for autoimmune diseases, especially for thyroid disorders.

The LH:FSH Ratio in Functional Hypothalamic Amenorrhea: An Observational Study

BACKGROUND

In functional hypothalamic amenorrhea (FHA), luteinizing hormone and follicle-stimulating hormone levels show high interindividual variability, which significantly limits their diagnostic value in differentiating FHA from polycystic ovary syndrome (PCOS). Our aim was to profile the LH:FSH ratio in a large sample of patients with well-defined FHA.

METHODS

This observational study included all consecutive patients with FHA presenting to the Department of Gynecologic Endocrinology and Reproductive Medicine, Medical University of Vienna, between January 2017 and August 2023. The main parameters of interest were the LH level, the FSH level, and the LH:FSH ratio. In a subgroup analysis, we compared the LH:FSH ratio of patients with PCO morphology (PCOM) on ultrasound with that of patients without PCOM.

RESULTS

A total of 135 patients were included. Only a minority of patients revealed FSH and LH levels ≤ 2.0 mIU/mL (13% and 39%, respectively). Most patients (81.5%) had an LH:FSH ratio ≤ 1.0, while a minority (2.2%) had a ratio ≥ 2.1. The LH:FSH ratio was similar in patients with and without PCOM.

CONCLUSION

In a well-defined FHA sample, the LH:FSH ratio was ≤ 1 in most patients. The LH:FSH ratio may prove useful in distinguishing FHA from PCOS but needs further investigation.

Prolactin levels in functional hypothalamic amenorrhea: a retrospective case-control study

PURPOSE

Functional hypothalamic amenorrhea (FHA) is due to hypothalamic dysregulation. Literature lacks data about prolactin in FHA women, although both prolactin levels and FHA are associated with stress. Moreover, polycystic ovarian morphology is common in FHA and there is an association between FHA and polycystic ovary syndrome. Thus, the aim of this study was to assess prolactin levels in FHA patients and controls with a special focus on factors influencing prolactin levels, that could be considered as "sensors" of the hypothalamic-pituitary dysregulation.

METHODS

In a retrospective cohort study, 140 women with clearly defined FHA were compared to 70 healthy, normally ovulating women matched for age. The main outcome parameter was prolactin. Factors associated with prolactin levels > 12 µg/L were tested using a multivariable binary logistic regression model.

RESULTS

The median prolactin level was 11.5 µg/L (interquartile range, IQR 7.5-14.4), which was similar to the control group (median 10.7, IQR 8.3-14.5; p = 0.065). Only two women had hyperprolactinemia (prolactin > 25 µg/L; 1.4%). In a multivariable binary logistic regression model eating disorder (odds ratio, OR 0.206; p = 0.040), excessive exercise (OR 0.280; p = 0.031) and TSH (OR 1.923; p = 0.020) were significantly associated with prolactin levels > 12 µg/L.

CONCLUSION

Women with FHA have similar prolactin levels to healthy age-matched individuals. Eating disorders and excessive exercise where associated with prolactin levels < 12 µg/L, in contrast to TSH.

Prevalence of functional hypothalamic amenorrhea in a cohort of women referred because of polycystic ovary syndrome

In this unselected population of women referred to a center specialized in gynecologic endocrinology for suspicion of PCOS, a minimum rate of misdiagnosed FHA patients of about 2% was found. It is necessary to evaluate reliable markers for the differential diagnosis between PCOS and FHA to avoid incorrect treatment, which might lead to negative long-term effects in women with undiagnosed FHA.

Functional Hypothalamic Amenorrhea and Preclinical Cardiovascular Disease

CONTEXT

Endothelial dysfunction is a preclinical cardiovascular disease (CVD) marker. Due to various neuroendocrine aberrations, functional hypothalamic amenorrhea (FHA) may be a sex-specific risk factor for CVD in young women.

OBJECTIVE

To investigate endothelial function in women with FHA, compared with eumenorrheic controls and recently menopausal women.

METHODS

We performed a cross-sectional analysis among women with FHA (n = 30), eumenorrheic controls (n = 29), and recently menopausal women (n = 30). FHA was defined as amenorrhea ≥3 consecutive months, estradiol <50 pg/mL, follicle-stimulating hormone (FSH) < 10 mIU/mL, and luteinizing hormone (LH) < 10 mIU/mL, excluding other etiologies. Participants were recruited through obstetrics and gynecology referrals, social media advertising, and review of electronic health records. Preclinical CVD was measured using EndoPAT 2000 to calculate reactive hyperemic index (RHI). RHI ≤1.67 indicates endothelial dysfunction.

RESULTS

Mean estradiol levels in women with FHA, as compared with eumenorrheic controls and recently menopausal women, were 29.0 ± 18.1, 46.4 ± 15.7, and 10.9 ± 14.4 pg/mL (P < .0001), respectively. Women with FHA had lower insulin (P = .0095) and higher cortisol (P = .0004) compared with controls. RHI was significantly lower in women with FHA compared with eumenorrheic controls and recently menopausal women (1.8 ± 0.5 vs 2.2 ± 0.5 vs 2.2 ± 0.6, respectively; P = .008), and 35% of women with FHA had RHI ≤1.67, consistent with endothelial dysfunction.

CONCLUSION

These results demonstrate endothelial dysfunction in 1 out of 3 young women with FHA. FHA may be a contributor to preclinical CVD, and it is not explained by hypoestrogenemia alone.

Unveiling the Effects of Triptorelin on Endocrine Profiles: Insights From Healthy, Polycystic Ovary Syndrome, and Hypothalamic Amenorrhea Women

Triptorelin, a synthetic gonadotropin-releasing hormone (GnRH) agonist, has garnered increasing attention for its profound effects on endocrine profiles across diverse populations. This review article explores triptorelin's impact on women's health by examining its effects on healthy individuals, those with polycystic ovary syndrome (PCOS), and those experiencing hypothalamic amenorrhea (HA). The mechanism of triptorelin involves a transient surge in gonadotropin release, followed by receptor desensitization, leading to downregulation of the hypothalamus-pituitary-gonadal (HPG) axis. In healthy women, triptorelin's controlled modulation of the HPG axis is a foundation for assisted reproduction techniques. In PCOS, it offers promise in restoring ovulatory function and mitigating hyperandrogenism. For HA individuals, triptorelin's potential to restore proper GnRH pulsatility emerges as a therapeutic avenue. This review emphasizes the importance of personalized approaches based on specific health conditions, highlighting triptorelin's versatility and potential applications beyond its current scope. As research progresses, triptorelin's role in endocrine management is poised to reshape women's health by optimizing hormonal equilibrium and overall well-being.

Functional Hypothalamic Amenorrhea: Recognition and Management of a Challenging Diagnosis

Functional hypothalamic amenorrhea is responsible for approximately a third of the cases of secondary amenorrhea. The condition is a result of disturbances in gonadotropin-releasing hormone pulsatile secretion at the level of the hypothalamus, which in turn disrupts gonadotropin secretion. It is due to psychosocial stress, disordered eating, and/or excessive exercise. Often, however, it is a combination of more than one etiology, with a possible role for genetic or epigenetic predisposition. The dysfunctional gonadotropin-releasing hormone release leads to the cessation of ovarian function, resulting in amenorrhea, infertility, and a long-term impact on affected women's bone health, cardiovascular risk, cognition, and mental health. Functional hypothalamic amenorrhea is a diagnosis of exclusion, and treatment involves identifying and reversing the underlying cause(s). The aim of this concise review is to summarize the current knowledge of functional hypothalamic amenorrhea, review its pathophysiology and the adverse health consequences, and provide recommendations for diagnosis and management of this condition. Furthermore, this review will emphasize the gaps in research on this common condition impacting women of reproductive age all over the world.

Stress and polycystic ovarian morphology in functional hypothalamic amenorrhea: a retrospective cohort study

BACKGROUND

Women with functional hypothalamic amenorrhea (FHA) reveal polycystic ovarian morphology (PCOM) in up to 50%. If stress sensitivity in women with polycystic ovary syndrome (PCOS) is the reason why PCOS women are prone to develop FHA, patients with FHA caused by stress should reveal PCOM more often.

METHODS

In a retrospective cohort study, 38 stress-associated and 38 excessive exercise-induced FHA women were included. The main outcome parameter was PCOM. In addition, the focus was on general patient characteristics as well as on prolactin, dehydroepiandrosterone-sulphate (DHEAS), and anti-Mullerian hormone (AMH).

RESULTS

PCOM was found in 34/76 patients (44.7%). The stress group showed a higher prevalence of PCOM than the excessive exercise group (57.9% versus 31.6%, p = 0.019) as well as higher prolactin levels (median 13.2ng/mL versus 11.7ng/mL, p = 0.008) and a trend towards higher DHEAS levels (p = 0.058).

CONCLUSIONS

In FHA women, the PCOM prevalence was significantly higher in the stress-group than in the excessive exercise-group. The well-known stress sensitivity in women with PCOS might explain why PCOS women are prone to develop FHA as well as the high PCOM prevalence in FHA women.

The Prevalence of Fallopian Tube Occlusion in Women with Polycystic Ovary Syndrome Seems Similar to Non-Subfertile Women: A Retrospective Cohort Study

There are limited data on how non-infectious risk factors influence tubal patency in women with subfertility. With hormonal shifts influencing tubal secretions, it has been argued that subfertile women with polycystic ovary syndrome (PCOS) have lower tubal patency. In a retrospective study, 216 women, who underwent diagnostic evaluation for PCOS and infertility, were included. Fallopian tube patency was tested using HSG, HyCoSy, and laparoscopic chromopertubation in 171 (79.2%), 28 (13.0%), and 17 (7.9%), respectively. Bilateral patency was found in 193 women (89.4%), unilateral patency in 13 (6.0%) and bilateral occlusion in 10 (4.6%) patients. Women with PCOS phenotypes C (odds ratio, OR 0.179, 95% CI: 0.039–0.828) and D (OR 0.256, 95% CI: 0.069–0.947) demonstrated lower risks for Fallopian tube occlusion. In conclusion, our data suggest that about 5% of infertile women with PCOS also have bilateral tubal occlusion, which seems similar to the rate in non-subfertile women. With 11% of participants having unilateral or bilateral tubal occlusion, this should reassure women with PCOS that their hormonal challenges do not seem to increase their risk for tubal factor subfertility.
