Abstract
Managing patients unable to produce sex steroids using gonadotropins to mimic minipuberty in hypogonadotropic hypogonadism, or sex steroids in patients with Klinefelter or Turner syndrome, is promising. There is a need to pursue research in this area, with large prospective cohorts and long-term data before these treatments can be routinely considered.

Abstract
STUDY OBJECTIVE Available data on the clinical significance of low serum anti-Müllerian hormone (AMH) levels in female adolescents are limited. The aim of this study was to elucidate age-related changes in low serum AMH levels in adolescents and to identify predictive factors for AMH progression. METHODS A retrospective review was conducted on a series of female adolescents aged 11-19 years with low serum AMH levels (<1.19 ng/mL) who underwent additional AMH tests at least 1 year apart. Participants who showed an increase in the subsequent AMH test (>1.6 ng/mL) (Group 1) were compared with those who did not (Group 2). RESULTS Among 1655 adolescents who underwent AMH testing at least once from 2010 to 2022, 75 participants (4.5%) exhibited low AMH levels (<1.19 ng/mL), excluding primary ovarian insufficiency. A notable increase in serum AMH levels (>1.6 ng/mL) was confirmed in 7 (30.4%) of 23 female adolescents who underwent relevant follow-up testing. Group 1 had higher initial AMH levels and lower initial follicle-stimulating hormone levels than Group 2 (1.0 vs 0.59 ng/mL, P = .001 and 4.4 vs 9.8 mIU/mL, P = .015, respectively). Ovarian volume did not differ between the groups (3.8 vs 4.4 cm3, P = .465). None of the participants with initial AMH levels under 0.75 ng/mL showed an increase in AMH levels during follow-up. CONCLUSION These findings suggest that low serum AMH levels in adolescents may have other explanations in addition to being indicative of a low ovarian reserve. Prospective studies involving a larger number of participants will aid in predicting AMH improvement in adolescents.

Abstract
This review explores the challenges in the diagnosis of hypogonadotropic hypogonadism, the transition of care from paediatric to adult care and the considerable health implications of this condition. The role gynaecologists and general practitioners have in managing hormone replacement therapy and reproductive potential is also highlighted. The fertility treatment options, which include ovulation induction with gonadotrophins and in-vitro fertilisation, are discussed in detail along with highlighting the fact that anovulation and markers of low ovarian reserve prior to priming treatment may not be reflective of poor reproductive potential. The holistic management of women with hypogonadotropic hypogonadism is still not standardised and evidence for subfertility management is scarce. This review aims to highlight this concern and provide guidance by evaluating current evidence.

Abstract
AbstractPolycystic ovary syndrome (PCOS) is the most common gynecological endocrine disorders affecting up to 10% of all females in their reproductive age, and its cause of onset is still elusive. A spectrum of recent research reflected diverse associations between increased plasma level of anti-Mullerian hormone (AMH) and different clinical features of PCOS. Since AMH levels reflect the pool of growing follicles that potentially can ovulate, it can be stated that serum AMH levels can be used to assess the “functional ovarian reserve,” rather mentioning it as the “ovarian reserve.” AMH also appears to be a premier endocrine parameter for the assessment of atrophied ovarian follicular pool in response to age of individuals. AMH hinders the follicular development as well as the follicular recruitment and ultimately resulting in follicular arrest which is the key pathophysiologic condition for the onset of PCOS. Furthermore, FSH-induced aromatase activity remains inhibited by AMH that aids emergence of other associated clinical signs of PCOS, such as excess androgen, followed by insulin resistance among the PCOS individuals. Given the versatile association of AMH with PCOS and scarcity in literature explaining the underling mechanisms how AMH relates with PCOS, this review article will discuss the roles of AMH in the pathogenesis of PCOS which may introduce a new era in treatment approach of PCOS.

Abstract
BACKGROUND To evaluate in women with functional hypothalamic amenorrhea (FHA), whether there is a difference between patients with and without polycystic ovarian morphology (PCOM) concerning the response to a gonadotropin releasing hormone (GnRH) stimulation test and to pulsatile GnRH treatment. METHODS In a retrospective observational study, 64 women with FHA who underwent a GnRH stimulation test and 32 age-matched controls without PCOM were included. Pulsatile GnRH treatment was provided to 31 FHA patients and three-month follow-up data were available for 19 of these. RESULTS Serum levels of gonadotropins and estradiol were lower in FHA women than in controls (p < 0.05). FHA patients revealed PCOM in 27/64 cases (42.2%). FHA patients without PCOM revealed lower anti-Müllerian hormone (AMH) levels than controls (median 2.03 ng/mL, IQR 1.40-2.50, versus 3.08 ng/mL, IQR 2.24-4.10, respectively, p < 0.001). Comparing FHA patients with and without PCOM, the latter revealed lower AMH levels, a lower median LH increase after the GnRH stimulation test (240.0%, IQR 186.4-370.0, versus 604.9%, IQR 360.0-1122.0; p < 0.001) as well as, contrary to patients with PCOM, a significant increase in AMH after three months of successful pulsatile GnRH treatment (median 1.69 ng/mL at baseline versus 2.02 ng/mL after three months of treatment; p = 0.002). CONCLUSIONS In women with FHA without PCOM, the phenomenon of low AMH levels seems to be based on relative gonadotropin deficiency rather than diminished ovarian reserve. AMH tended to rise after three months of pulsatile GnRH treatment. The differences found between patients with and without PCOM suggest the former the existence of some PCOS-specific systemic and/or intra-ovarian abnormalities.

Abstract
CONTEXT In men with congenital hypogonadotropic hypogonadism (CHH), gonadotropin deficiency and testicular impairment exist since fetal development and persist throughout life. In a few reported cases of acquired HH (AHH), HH onset occurs mainly post pubertally. OBJECTIVE This work aimed to compare the natural history and reproductive status in large series of CHH and lesional AHH evaluated in a single expert academic center. METHODS We included 172 controls, 668 male HH patients (CHH: n = 201 [age 16.9 ± 9.0 years], lesional AHH: n = 467 [age 45.6 ± 18.4 years]) caused by hypothalamic and/or pituitary tumors (mainly adenomas and craniopharyngiomas) or infiltrative/traumatic diseases. RESULTS At diagnosis, CHH were significantly younger, with 52.9% diagnosed before age 18 years, compared to only 9.6% of AHH patients. Cryptorchidism (21.9% vs 0.3%) and micropenis were more prevalent in CHH than AHH patients. Low testicular volume (TV) was present in 97% of patients with CHH (mean TV: 3.4 ± 2.7 mL) but in only 30% of those with AHH (mean TV: 20.8 ± 5.0 mL). Whereas no men with persistent CHH had spontaneous fertility, 70.4% of AHH men fathered at least one child without medical therapy. Total testosterone was lower both in CHH and AHH patients than in controls. Compared to controls, circulating gonadotropins and testicular peptides (insulin-like factor-3 and inhibin B) were decreased both in CHH and AHH, but were significantly higher in patients with AHH. CONCLUSION In AHH patients, the HH has later onset and is less severe than in CHH and the phenotype can overlap with that of individuals with normal laboratory values. Our data suggest that age at diagnosis is a predictor of the reproductive phenotype in AHH.

Abstract
OBJECTIVE To determine the usefulness of Anti-Müllerian Hormone (AMH) and antral follicle count (AFC) as an ovarian reserve marker in hypogonadotropic hypogonadism (HH) patients and to find a limit value for the gonadotropin levels in the diagnosis of HH patients. STUDY DESIGN It is a retrospective cross-sectional single-center study. One hundred ninety-nine women with HH and 171 healthy controls with no cycle disorders were included into this study. Continuous variables were expressed as mean ± standard deviation. Statistical comparisons were carried out according to the intention to treat by Student's t-test, Mann-Whitney U test, where appropriate. Receiver operating characteristic curve-ROC was used to represent the sensitivity and specificity pair corresponding to decision threshold of FSH and LH levels in HH diagnosis. P < 0.05 was accepted to be statistically significant. RESULTS There was not any statistically significant difference between HH and control group regarding the age (23.94 ± 6.56 vs. 23.92 ± 3.01, respectively; p = 0.09). Serum AMH levels didn't show statistically significant difference between HH and control group (3.26 ± 2.61 ng/mL vs. 3.15 ± 1.46 ng/mL, respectively; p = 0.11). The difference of AFC between HH and control group was statistically significant (6.67 ± 6.33 vs. 10.91 ± 2.92, respectively; p < 0.001). Follicle-stimulating hormone (FSH), Luteinizing-hormone (LH) and Estradiol (E2) levels between the groups were found to be significantly different. Area under the receiver operating characteristic curve-ROC for FSH was 0.98 and for LH was 0.96. For the diagnosis of HH, FSH levels lower than 3.05 IU/L (with a sensitivity of 92% and specificity of 94%) and LH levels lower than 1.55 IU/L (with a sensitivity of 91% and specificity of 92%) can be used. CONCLUSION In conclusion, serum AMH levels reflect the follicle cohort in HH cases validly with negligible underestimation of ovarian reserve. FSH < 3.05 IU/L and LH < 1.55 IU/L could be used with high sensitivity and specificity for the diagnosis of HH.

Abstract
CONTEXT Evaluation of the infertile female requires an understanding of ovulation and biomarkers of ovarian reserve. Antimüllerian hormone (AMH) correlates with growing follicles in a menstrual cycle. Increasingly, AMH has been used as a "fertility test." This narrative review describes how to integrate the use of AMH into diagnosis and treatment. METHODS A PubMed search was conducted to find recent literature on measurements and use of serum AMH as a marker of ovarian reserve and in treatment of infertility. RESULTS Serum AMH estimates ovarian reserve, helps determine dosing in ovarian stimulation, and predicts stimulation response. As such, AMH is a good marker of oocyte quantity but does not reflect oocyte health or chances for pregnancy. Screening of AMH before fertility treatment should be used to estimate expected response and not to withhold treatment. Low AMH levels may suggest a shortened reproductive window. AMH levels must be interpreted in the context of the endogenous endocrine environment where low follicle-stimulating hormone, due to hypogonadotropic hypogonadism or hormonal contraceptive use, may lower AMH without being a true reflection of ovarian reserve. In addition, there is an inverse correlation between body mass index and AMH that does not reflect ovarian response. CONCLUSION AMH is a useful marker of ovarian reserve in reproductive-aged women. Increased screening of noninfertile women requires a thorough knowledge of situations that may affect AMH levels. In no situation does AMH reflect oocyte health or chances for conception. Age is still the strongest driver in determining success rates with fertility treatments.

Abstract
Normosmic idiopathic hypogonadotropic hypogonadism (nIHH) is a rare disorder with pubertal delay, normal sense of smell. nIHH with a fibroblast growth factor receptor 1 mutation is much more common in adult males but is rarely reported in females. In addition, the assessment and monitoring of ovarian function in nIHH females has often been ignored. We report a 24-year-old nIHH female with the complaint of primary amenorrhea and delayed secondary sexual traits development. Whole-Exome Sequencing analysis revealed a novel mutation in the third exon of fibroblast growth factor receptor 1 gene (c.289 G > A), which resulted in the replacement of glycine acid with serine. Then the patient was recommended to start with the hormone therapy (HT). After several months of estrogen combined with progesterone replacement, the patient had regular menstruation. The breast development and genital development gradually became Tanner stage 5. Anti-Müllerian hormones (AMHs) were also evaluated and the serum AMH level keeps fluctuating within the normal reference range. We highlight the great variability of fibroblast growth factor receptor 1 mutation phenotypes and the evaluation of ovarian reserve in nIHH, and the hormone replacement therapy is necessary to improve secondary sexual development for patients with nIHH.

Abstract
OBJECTIVES Determine variability of serum anti-Müllerian hormone (AMH) levels during ovulatory menstrual cycles between different women (inter-participant), between non-consecutive cycles (inter-cycle) and within a single cycle (intra-cycle) in healthy women. METHODS Eligible participants were women aged 18-40 years with regular ovulatory menstrual cycles. Serum samples were collected every second day during two non-consecutive menstrual cycles. AMH levels were measured in triplicate using the Elecsys® AMH Plus immunoassay (Roche Diagnostics). AMH level variability was evaluated using mixed-effects periodic regression models based on Fourier series. The mesor was calculated to evaluate inter-participant and inter-cycle variability. Inter- and intra-cycle variability was evaluated using peak-to-peak amplitudes. Separation of biological and analytical coefficients of variation (CVs) was determined by analysing two remeasured AMH levels (with and without original AMH levels). RESULTS A total of 47 women were included in the analysis (42 assessed over two cycles; five one cycle only). CV of unexplained biological variability was 9.61%; analytical variability was 3.46%. Inter-participant variability, given by time-series plots of AMH levels, was greater than inter-cycle variability. Between individual participants, both mesor and peak-to-peak amplitudes proved variable. In addition, for each participant, intra-cycle variability was higher than inter-cycle variability. CONCLUSIONS Inter-participant and intra-cycle variability of AMH levels were greater than inter-cycle variability. Unexplained biological variability was higher than analytical variability using the Elecsys AMH Plus immunoassay. Understanding variability in AMH levels may aid in understanding differences in availability of antral ovarian follicles during the menstrual cycle, which may be beneficial in designing gonadotropin dosage for assisted reproductive technology.

Abstract
AIM The aim of this study was to evaluate the general characteristics, menstruation status, and fertility outcomes of patients with hypogonadotropic hypogonadism (HH). METHODS We evaluated 16 patients with HH who visited our institution between April 2012 and March 2016 with a complaint of amenorrhea. RESULTS Four (25%) patients had primary amenorrhea and the remaining 12 (75%) cases had secondary amenorrhea. Among the patients with primary amenorrhea, weight loss was considered to be the underlying cause in one (25%) patient, whereas the remaining three (75%) cases were idiopathic HH. Among HH cases with secondary amenorrhea, six (50%) developed amenorrhea following weight loss, whereas the remaining six cases were of unknown etiology. Among the 16 patients with HH, we observed the sporadic restart of the menstrual cycle in four (25%) women during follow-up. Infertility treatment was administered to nine patients with HH who wished to become pregnant. Clomiphene citrate was effective in four patients with secondary amenorrhea and induced follicular development. Seven of nine patients with HH (77.8%) became pregnant following infertility treatment. In some cases of HH, the serum levels of gonadotropin increased sporadically during follow-up, regardless of the recovery of menstruation. We followed one patient with HH for more than 20 years. Although her gonadotropin levels were generally low and sometimes fluctuated without spontaneous menstruation, they increased dramatically to menopausal levels at 50 years of age. However, they again decreased to hypogonadotropic levels. CONCLUSION As the pathophysiology varied widely among patients, the etiologic factors underlying HH might also vary.

Abstract
BACKGROUND Subjects with hypo-or hypergonadotropic hypogonadism need hormone replacement therapy (HRT) to initiate puberty and maintain it with a normal hormonal status. While general recommendations for the management of HRT in adults have been published, no systematic suggestions focused on adolescents and young adults. The focus of this review is the HRT in males and females with hypogonadism, from puberty to late reproductive age, covering the different management options, encompassing sex steroid or gonadotropin therapy, with discussion of benefits, limitations and specific considerations of the different treatments. METHODS We conducted an extensive search in the 3 major scientific databases (PubMed, EMBASE and Google Scholar) using the keywords "hormonal replacement therapy", "hypogonadism", "bone mineral density", "estradiol/testosterone", "puberty induction", "delayed puberty". Case-control studies, case series, reviews and meta-analysis published in English from 1990 to date were included. RESULTS By considering the available opportunities for fertility induction and preservation, we hereby present the proposals of practical schemes to induce puberty, and a decisional algorithm to approach HRT in post-pubertal adolescents. CONCLUSIONS A condition of hypogonadism can underlie different etiologies involving the hypothalamic-pituitary-gonadal axis at different levels. Since the long-terms effects of hypogonadism may vary and include not only physical outcomes related to sex hormone deficiencies, but also psychological problems and implications on fertility, the initiation, maintenance and consolidation of puberty with different pharmaceutical options is of utmost importance and beside pubertal development, optimal uterine and testicular growth and adequate bone health should consider also the psychosocial wellbeing and the potential fertility.

Abstract
Primary ovarian insufficiency (POI) is a highly heterogeneous condition, and its underlying causes remain to be clarified in a large fraction of patients. Congenital disorders of glycosylation (CDG) are multisystem diseases caused by mutations of a number of genes involved in N-glycosylation or O-glycosylation, and the most frequent form is PMM2-CDG (alias, CDG-Ia) resulting from biallelic mutations in PMM2 encoding phosphomannomutase-2 involved in N-glycosylation. Here, we examined a 46,XX Japanese female with syndromic POI accompanied by an undetectable level of serum anti-Müllerian hormone (AMH). Whole exome sequencing identified biallelic pathogenic mutations of PMM2 (a novel c.34G>C:p.(Asp12His) of maternal origin and a recurrent c.310C>G:p.(Leu104Val) of paternal origin) (NM_000303.3), and N-glycosylation studies detected asialotransferrin and disialotransferrin characteristic of PMM2-CDG, in addition to normally glycosylated tetrasialotransferrin. Clinical assessment showed cerebellar hypotrophy, which is a fairly characteristic and highly prevalent feature in PMM2-CDG, together with multiple non-specific features reported in PMM2-CDG such as characteristic face, intellectual disability, skeletal abnormalities, and low blood antithrombin III value. These results including the undetectable level of serum AMH, in conjunction with previously reported findings suggestive of the critical role of glycosylation in oocyte development and function, imply that PMM2-CDG almost invariably leads to POI primarily because of the defective oogenesis and/or oocyte-dependent early folliculogenesis rather than the compromised bioactivity of FSH/LH with defective glycosylation. Thus, it is recommended to examine PMM2 in patients with syndromic POI, especially in those with cerebellar ataxia/hypotrophy.

Abstract
STUDY QUESTION Are serum levels of anti-Müllerian hormone (AMH) normal in patients with functional hypothalamic anovulation (FHA)? SUMMARY ANSWER Our study confirms that in the general FHA population, serum AMH levels are not decreased, but if patients with polycystic ovarian morphology (PCOM) are excluded, levels become significantly lower, as in other situations of gonadotropic insufficiency. WHAT IS KNOWN ALREADY In most situations of low LH (physiological, pharmacological or pathological), serum AMH levels are low. However, paradoxically, many publications have reported normal or even increased serum AMH levels in FHA patients. STUDY DESIGN, SIZE, DURATION Retrospective observational study conducted in an academic centre. The data concerning the study population was collected between 2006 and 2015 from a database including clinical, biological and ultrasound information. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 45 FHA patients were compared to 37 controls matched based on age and body mass index (BMI). Serum LH, FSH, androstenedione, total testosterone, prolactin and AMH levels were measured by immunoassay. We defined PCOM with strict criteria: a follicle number per ovary (FNPO) ≥ 12 or ≥ 19 per ovary, depending on the date on which the assessment was carried out and the ultrasound device. An AMH level ≥ 35 pmol/l could be a substitute for an excess FNPO. Controls meeting these criteria were not included in this study. MAIN RESULTS AND THE ROLE OF CHANCE There was no significant difference in the ranges of AMH levels between FHA and controls. Using strict criteria to define PCOM status, 46.7% of FHA patients had PCOM. After excluding these patients, the levels of AMH were significantly lower (P < 0.002) in FHA patients compared to controls. Within the FHA group, patients with PCOM had significantly higher ranks of AMH levels and BMI than those without PCOM. However, within the PCOM+ subgroup, the ranks of LH, FSH and A levels were still lower than in controls (P < 0.0001, <0.002 and <0.05, respectively). The positive correlation between AMH and LH was significant in the controls but not in the FHA group. However, in the FHA PCOM+, there was a strong positive correlation between BMI and LH. LIMITATIONS, REASONS FOR CAUTION This is a retrospective study; our controls did not represent the general population as they were recruited in an ART centre; we used a modified classification for PCOM using follicle count and/or AMH level with in-house thresholds to define the follicle excess; the AMH assay used is no longer commercially available. WIDER IMPLICATIONS OF THE FINDINGS Besides biasing the results of AMH assay in FHA patients, the presence of PCOM in FHA patients despite low gonadotropin and androgen levels raises the issue of epigenetically acquired amplification of androgen and/or FSH sensitivity within granulosa cells from polycystic ovaries. In terms of clinical practice, it seems important not to diagnose a low ovarian reserve in FHA patients too quickly on the basis of a decreased AMH level alone. On the contrary, a high AMH level in the context of a menstrual disorder and PCOM should not lead to a misdiagnosis of polycystic ovary syndrome (PCOS) if the basal LH is low.

Abstract
STUDY QUESTION Can cytochrome P450 oxidoreductase deficiency (PORD) be revealed in adult women with menstrual disorders and/or infertility? SUMMARY ANSWER PORD was biologically and genetically confirmed in five adult women with chronically elevated serum progesterone (P) who were referred for oligo-/amenorrhea and/or infertility. WHAT IS KNOWN ALREADY PORD is an autosomal recessive disease typically diagnosed in neonates and children with ambiguous genitalia and/or skeletal abnormalities. It is responsible for the decreased activity of several P450 enzymes, including CYP21A2, CYP17A1 and CYP19A1, that are involved in adrenal and/or gonadal steroidogenesis. Little is known about the optimal way to investigate and treat patients with adult-onset PORD. STUDY DESIGN, SIZE, DURATION In this series, we report five adult females who were evaluated in three tertiary endocrine reproductive departments between March 2015 and September 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS Five women aged 19-38 years were referred for unexplained oligo-/amenorrhea and/or infertility. Genetic testing excluded 21-hydroxylase deficiency (21OH-D), initially suspected due to the increased 17-hydroxyprogesterone (17-OHP) levels. Extensive phenotyping, steroid profiling by mass spectrometry, pelvic imaging and next-generation sequencing of 84 genes involved in gonadal and adrenal disorders were performed in all patients. IVF followed by frozen embryo transfer (ET) under glucocorticoid suppression therapy was performed for two patients. MAIN RESULTS AND THE ROLE OF CHANCE All patients had oligomenorrhea or amenorrhea. None had hyperandrogenism. Low-normal serum estradiol (E2) and testosterone levels contrasted with chronically increased serum P and 17-OHP levels, which further increased after adrenocorticotrophic hormone (ACTH) administration. Despite excessive P, 17OH-P and 21-deoxycortisol rise after ACTH stimulation suggesting non-classic 21OH-D, CYP21A2 sequencing did not support this hypothesis. Basal serum cortisol levels were low to normal, with inadequate response to ACTH in some women, suggesting partial adrenal insufficiency. All patients harbored rare biallelic POR mutations classified as pathogenic or likely pathogenic according to the American College of Medical Genetics and Genomics standards. Pelvic imaging revealed bilateral ovarian macrocysts in all women. IVF was performed for two women after retrieval of a normal oocyte number despite very low E2 levels during ovarian stimulation. Frozen ET under glucocorticoid suppression therapy led to successful pregnancies. LIMITATIONS, REASONS FOR CAUTION The number of patients described here is limited and these data need to be confirmed on a larger number of women with non-classic PORD. WIDER IMPLICATIONS OF THE FINDINGS The diagnosis of PORD must be considered in infertile women with chronically elevated P and 17OH-P levels and ovarian macrocysts. Differentiation of this entity from non-classic 21OH-D is important, as the multiple enzyme deficiency requires a specific management. Successful fertility induction is possible by IVF, providing that P levels be sufficiently suppressed by glucocorticoid therapy prior to implantation. STUDY FUNDING/COMPETING INTEREST(S) No specific funding was used for this study. There are no potential conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
Abstract
Background
Hypogonadotropic hypogonadism (HH) is a rare condition in which there is gonadal hypofunction due to absence of gonadotropin drive. In this condition, there are very low serum levels of gonadotropins. Pituitary gland may itself have some disease or disorder, or there may be loss of gonadotropin-releasing hormone (GnRH) pulses from the hypothalamus. The pharmacological interventions in HH women formed the basis for superovulation strategies for assisted reproduction techniques (ART) with a special reference to the role of LH and its impact on oocyte and embryo quality.
Results
The medians ±inter quartile ranges for number of oocytes retrieved, number of MII oocytes, and number of embryos transferred were 5±7, 4±3, and 3±1 respectively. The pregnancy rate was 31.5% for this group of patients. The live birth rate and miscarriage rate were 21% and 11.5% respectively.
Conclusion
The reproductive outcomes of patients of hypogonadotrophic hypogonadism are reasonable after ICSI and clinical trials are recommended to corroborate this concern.

Abstract
Many of the recent advances in our understanding of human reproductive biology and its genetic basis have arisen directly via the genetic investigation of patients with Kallmann syndrome and their families. The disease is characterised by the association of an isolated defect in the secretion (or, less commonly, action) of gonadotropin-releasing hormone (GnRH) and consequent infertility, with anosmia and potentially other associated non-reproductive features. GnRH-producing neurons are located in the hypothalamic brain region after a peculiar migration during embryonic life. To date, different genes affecting GnRH neuron development/migration have so far been implicated in Kallmann syndrome, but our knowledge of the genetic basis of the syndrome remains incomplete. From a clinical point of view, the disease has suffered from a lack of definitive diagnosis and treatment, and although progress has been made in terms of timely diagnosis and evidence-based treatment of patients, implementation remains inconsistent. These aspects will be discussed in this review, which examines new strategies for arriving at more evidence-based and patient-centred medical practice in Kallmann syndrome.

Abstract
BACKGROUND The aim of this study was to define the performance characteristics of the Mindray chemiluminescence assay for anti-Müllerian hormone (AMH) detection. DESIGNS AND METHODS Intra-assay and total imprecision, analytical sensitivity, linearity, and interference were compared between the Mindray and Roche assays using pools of human serum according to Clinical and Laboratory Standards Institute protocols. Additionally, male and female reference intervals were established using serum specimens collected from otherwise healthy groups and patients with polycystic ovary syndrome (PCOS). RESULTS The intra-assay and total imprecision percent coefficients of variation for low and high AMH serum levels were 2.74%/ 3.01% and 5.41%/5.35% respectively. The limits of blank, detection, and quantitation were 0.007, 0.01, and 0.03 ng/ml, respectively. The assay displayed good linearity over the range of 0.01-23 ng/ml. The coefficient of determination (R2 ) of the Mindray versus Roche assays was 0.9713 with 411 samples with AMH concentrations ranging from 0.014 to 22.1 ng/ml. The slope and intercept of the regression equation were 0.9687 and 0.3419, respectively. There was no significant interference from triglycerides (up to 3000 mg/dl), bilirubin (up to 50 mg/dl), hemoglobin (up to 500 mg/dl), or total protein (up to 10 g/dl). Reference intervals showed the expected decrease in serum AMH levels with age in healthy women and increased levels in women with PCOS. CONCLUSION The Mindray AMH assay demonstrated acceptable analytical performance under routine conditions and is suitable for determining AMH levels in serum samples.

Abstract
RESEARCH QUESTION Which clinical features, along with biological features, ultrasound features, or both, are the most strongly associated with either high or low anti-Müllerian hormone (AMH) levels in patients with polycystic ovary syndrome (PCOS)? DESIGN A retrospective cross-sectional study conducted within a university-affiliated reproductive endocrinology unit in Lille, France. A total of 639 patients with PCOS according to the Rotterdam Criteria and 137 control women were included. A comparison of clinical, hormonal, metabolic and ultrasound data in patients with PCOS and controls belonging to the first (Q1) and fourth (Q4) quartiles of their respective AMH ranges (discriminant analysis) was conducted. RESULTS In the PCOS group, patients in Q4 had higher LH levels and a more severe phenotype, but they were thinner and had lower levels of hyperinsulinaemia than patients in Q1. In the PCOS group, discriminant analysis yielded a highly significant model in which follicle number per ovary (FNPO) and serum LH were strongly and equally discriminating between Q4 and Q1 (R2 at 0.371 and 0.304, respectively, both P < 0.0001), whereas body mass index had less, although significant, effect (R2 = 0.075, P < 0.0001). In control women, discriminant analysis yielded a significant discriminant model, including only FNPO and age (R2 at 0.62 and 0.27, both P < 0.0001). CONCLUSION High serum AMH levels are associated with high serum LH levels and more severe features of PCOS. Conversely, the effect of hyperinsulinism may be greater in patients with lower serum AMH levels, suggesting independent effects of AMH and insulin on the phenotypic expression of PCOS.

Abstract
OBJECTIVE To investigate the association between baseline serum Anti-Müllerian hormone (AMH) levels and IVF/ICSI outcomes in women with polycystic ovary syndrome (PCOS). DESIGN Retrospective study. SETTING Reproductive medicine center in a hospital. POPULATION 2436 PCOS patients (Rotterdam criteria) who underwent their first fresh IVF/ICSI cycles were divided into three groups on the basis of the <25th (Group 1, n=611), 25 to 75th (Group 2, n=1216), or >75th (Group 3, n=609) percentile of baseline serum AMH level. INTERVENTIONS Baseline serum AMH levels measured on the 2-3 days of spontaneous menstrual cycle before IVF/ICSI treatment. MAIN OUTCOME MEASURES Live birth rate (LBR), cumulative live birth rate (CLBR), clinical pregnancy rate (CPR), and normal fertilization rate (FR). RESULTS The LBR, CPR, and FR were significantly increased in Group 1 than Group 2 and Group 3, however, CLBR was similar between the three groups. The LBR were 46.6%, 40.5%, and 39.4% in Group 1, Group 2, and Group 3 respectively. The CPR were 53.0%, 47.0%, and 45.5%, respectively. The FR was highest in Group 1 (61.7%, P<0.05), but there was no uniform reverse trend with the AMH level. CLBR were 68.7%, 70.4%, and 71.3%, respectively. Although women in Group 1 were older (p < 0.05) and had higher body mass index (BMI) (p < 0.05), binomial logistic regression analysis used age, BMI, FSH, and AMH as independent variables indicated that only AMH was significantly associated with LBR and CPR. Nevertheless, binomial logistic regression analysis used age, BMI, FSH, AMH, and the number of retrieved oocytes as independent variables indicated that only the number of retrieved oocytes was significantly correlated with CLBR. After stratifying by age, the negative relationship between baseline AMH level and LBR and CPR remained only in the patients <30 years old. CONCLUSIONS Higher baseline AMH level in PCOS women resulted in lower LBR, CPR, and FR but did not influence CLBR.

Congenital Hypogonadotropic Hypogonadism with Anosmia and Gorlin Features Caused by a PTCH1 Mutation Reveals a New Candidate Gene for Kallmann Syndrome. Neuroendocrinology 2021; 111:99-114. [PMID: 32074614 DOI: 10.1159/000506640] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Accepted: 02/18/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND Two loci (CHD7 and SOX10) underlying Kallmann syndrome (KS) were discovered through clinical and genetic analysis of CHARGE and Waardenburg syndromes, conditions that include congenital anosmia caused by olfactory bulb (CA/OBs) defects and congenital hypogonadotropic hypogonadism (CHH). We hypothesized that other candidate genes for KS could be discovered by analyzing rare syndromes presenting with these signs. Study Design, Size, Duration: We first investigated a family with Gorlin-Goltz syndrome (GGS) in which affected members exhibited clinical signs suggesting KS. Participants/Materials, Methods: Proband and family members underwent detailed clinical assessment. The proband received detailed neuroendocrine evaluation. Genetic analyses included sequencing the PTCH1 gene at diagnosis, followed by exome analyses of causative or candidate KS/CHH genes, in order to exclude contribution to the phenotypes of additional mutations. Exome analyses in additional 124 patients with KS/CHH probands with no additional GGS signs. RESULTS The proband exhibited CA, absent OBs on magnetic resonance imaging, and had CHH with unilateral cryptorchidism, consistent with KS. Pulsatile Gonadotropin-releasing hormone (GnRH) therapy normalized serum gonadotropins and increased testosterone levels, supporting GnRH deficiency. Genetic studies revealed 3 affected family members harbor a novel mutation of PTCH1 (c.838G> T; p.Glu280*). This unreported nonsense deleterious mutation results in either a putative truncated Ptch1 protein or in an absence of translated Ptch1 protein related to nonsense mediated messenger RNA decay. This heterozygous mutation cosegregates in the pedigree with GGS and CA with OBs aplasia/hypoplasia and with CHH in the proband suggesting a genetic linkage and an autosomal dominant mode of inheritance. No pathogenic rare variants in other KS/CHH genes cosegregated with these phenotypes. In additional 124 KS/CHH patients, 3 additional heterozygous, rare missense variants were found and predicted in silico to be damaging: p.Ser1203Arg, p.Arg1192Ser, and p.Ile108Met. CONCLUSION This family suggests that the 2 main signs of KS can be included in GGS associated with PTCH1 mutations. Our data combined with mice models suggest that PTCH1 could be a novel candidate gene for KS/CHH and reinforce the role of the Hedgehog signaling pathway in pathophysiology of KS and GnRH neuron migration.

Abstract
Premature ovarian insufficiency (POI) is typically diagnosed when amenorrhea is combined with high gonadotrophins and hypoestrogenemia in a woman under 40 years of age, although, more rarely, POI can develop in adolescence and present with delayed puberty or amenorrhea, depending on the timing of follicular depletion or insult to the ovary. In a proportion of girls, the diagnosis may be made at an early stage of POI, presenting with abnormal uterine bleeding, when some follicular function is still retained. The natural history of POI in this group of patients is not clear; however, they could represent a subgroup with a unique opportunity for early intervention and thus the provision of fertility preservation options. While the etiology of POI in a large number of girls remains unknown, a growing number will be identified as carriers of genetic mutations, offering clinicians a yet greater opportunity to provide genetic counseling to other female family members. The aim of this review is to provide information regarding the etiology, diagnosis, and treatment of POI in adolescents while detailing the new options for fertility preservation when POI is diagnosed at an early stage.

GnRH stimulation testing and serum inhibin B in males: insufficient specificity for discriminating between congenital hypogonadotropic hypogonadism from constitutional delay of growth and puberty. Hum Reprod 2020; 35:2312-2322.

Abstract
Abstract
STUDY QUESTION
Are GnRH tests and serum inhibin B levels sufficiently discriminating to distinguish transient constitutional delay of growth and puberty (CDGP) from congenital hypogonadotropic hypogonadism (CHH) that affects reproductive health for life?
SUMMARY ANSWER
Both parameters lack the specificity to discriminate CDGP from CHH.
WHAT IS KNOWN ALREADY
GnRH tests and inhibin B levels have been proposed to differentiate CDGP from CHH. However, their diagnostic accuracies have been hampered by the small numbers of CHH included and enrichment of CHH patients with more severe forms.
STUDY DESIGN, SIZE, DURATION
The aim of this study was to assess the diagnostic performance of GnRH tests and inhibin B measurements in a large cohort of CHH male patients with the whole reproductive spectrum. From 2008 to 2018, 232 males were assessed: 127 with CHH, 74 with CDGP and 31 healthy controls.
PARTICIPANTS/MATERIALS, SETTING, METHODS
The participants were enrolled in two French academic referral centres. The following measurements were taken: testicular volume (TV), serum testosterone, inhibin B, LH and FSH, both at baseline and following the GnRH test.
MAIN RESULTS AND THE ROLE OF CHANCE
Among CHH patients, the LH response to the GnRH test was very variable and correlated with TV. Among CDGP patients, the LH peak was also variable and 47% of CHH patients had peak LH levels overlapping with the CDGP group. However, no patients with CDGP had an LH peak below 4.0 IU/l, while 53% CHH patients had LH peak below this threshold. Among CHH patients, inhibin B levels were also variable and correlated with TV and peak LH. Inhibin B was significantly lower in CHH patients than in CDGP patients but 50% of CHH values overlapped with CDGP values. Interestingly, all patients with CDGP had inhibin B levels above 35 pg/ml but 50% of CHH patients also had levels above this threshold.
LIMITATIONS, REASONS FOR CAUTION
As CHH is very rare, an international study would be necessary to recruit a larger CHH cohort and consolidate the conclusion reached here.
WIDER IMPLICATIONS OF THE FINDINGS
Peak LH and basal inhibin B levels are variable in both CHH and CDGP with significant overlap. Both parameters lack specificity and sensitivity to efficiently discriminate CHH from CDGP. This reflects the varying degree of gonadotropin deficiency inherent to CHH. These two diagnostic procedures may misdiagnose partial forms of isolated (non-syndromic) CHH, allowing them to be erroneously considered as CDGP.

Abstract
CONTEXT We previously reported the first female with a causative ESR1 gene variant, who exhibited absent puberty and high estrogens. At age 15 years, she presented with lower abdominal pain, absent breast development, primary amenorrhea, and multicystic ovaries. The natural history of complete estrogen insensitivity (CEI) in women is unknown. OBJECTIVE The purpose of this report is to present the neuroendocrine phenotype of CEI, identify potential ligands, and determine the effect of targeted treatment. DESIGN We have characterized gonadotropin pulsatility and followed this patient's endocrine profile and bone density over 8 years. Seventy-five different compounds were tested for transactivation of the variant receptor. A personalized medicine approach was tailored to our patient. SETTING Academic medical center. PATIENT OR OTHER PARTICIPANTS A 24-year-old adopted white female with CEI. INTERVENTION(S) The patient was treated with diethylstilbestrol (DES) for approximately 2.5 years. MAIN OUTCOME MEASURE(S) Induction of secondary sexual characteristics. RESULTS Luteinizing hormone (LH) pulse studies demonstrated normal pulsatile LH secretion, elevated mean LH, and mildly elevated mean follicle-stimulating hormone (FSH) in the presence of markedly increased estrogens. DES transactivated the variant ESR1 in vitro. However, DES treatment did not induce secondary sexual characteristics in our patient. CONCLUSIONS Treatment with DES was not successful in our patient. She remains hypoestrogenic despite the presence of ovarian cysts with a hypoestrogenic vaginal smear, absent breast development, and low bone mineral mass. Findings suggest additional receptor mechanistic actions are required to elicit clinical hormone responses.

Abstract
CONTEXT Human reproduction is mainly governed from the hypothalamic-adrenal-gonadal (HPG) axis, which controls both ovarian morphology and function. Disturbances in the secretion of other anterior pituitary hormones (and their respective endocrine axes) interfere with HPG activity and have been linked to fertility problems. In normal pregnancy, maintenance of homeostasis is associated with continuous changes in pituitary morphology and function, which need to be considered during hormone replacement in patients with hypopituitarism. DESIGN We conducted a systematic PubMed literature review from 1969 to 2019, with the following keywords: fertility and hypopituitarism, pregnancy and hypopituitarism, and ovulation induction and hypopituitarism. Case reports or single-case series of up to 2 patients/4 pregnancies were excluded. RESULTS Eleven publications described data on fertility (n = 6) and/or pregnancy (n = 7) in women with hypopituitarism. Women with hypopituitarism often need assisted reproductive treatment, with pregnancy rates ranging from 47% to 100%. In patients achieving pregnancy, live birth rate ranged from 61% to 100%. While glucocorticoids, levothyroxine, and desmopressin are safely prescribed during pregnancy, growth hormone treatment regimens vary significantly between countries, and several publications support a positive effect in women seeking fertility. CONCLUSIONS In this first systematic review on fertility, ovulation induction, and pregnancy in patients with hypopituitarism, we show that while literature is scarce, birth rates are high in patients achieving pregnancy. However, prospective studies are needed for evaluating outcomes in relationship to treatment patterns. Replacement therapy in hypopituitarism should always mimic normal physiology, and this becomes challenging with changing demands during pregnancy evolution.

Abstract
Since the historical use of gonadotrophin and estradiol levels to define the different anovulatory disorders has shown some limitations, the use of other markers such as anti-müllerian hormone (AMH) has been proposed. This review addresses the role of AMH in the differential diagnosis of anovulatory disorders, especially focusing on its value in the prognostic characterization of their severity. Current limitations and future clinical applications are discussed.

Abstract
Besides its interest for diagnosis, the finding of an elevated serum AMH level in PCOS has open major pathophysiological issues. This review addresses the three most important issues: 1- the role of AMH in the disturbed folliculogenesis of PCOS; 2- the role of AMH in the gonadotropin dysregulation of PCOS and 3- the role of AMH in the trans-generational transmission of PCOS. For each of those issues, the clinical and experimental evidences currently available are discussed and pathophysiological hypothesis are proposed.

Abstract
The classical definition of hypogonadism, used in adult medicine, as gonadal failure resulting in deficient steroid and gamete production, and its classification into hypergonadotropic and hypogonadotropic refer to primary gonadal and hypothalamic-pituitary disorders respectively and may lead to under- or misdiagnosis in pediatrics. Indeed, in children with primary gonadal failure, gonadotropin levels may be within the reference range for age. Conversely, since gonadotropins and steroids are normally low during childhood, it may prove impossible to show the existence of a hypogonadotropic state before pubertal age. Anti-Müllerian hormone (AMH) and inhibin B arise as more adequate biomarkers to assess gonadal function and increase the possibility of making an earlier diagnosis of hypogonadism in children, which may positively impact on timely management.

Abstract
OBJECTIVE To evaluate the hormonal profile, antral follicle count (AFC) and ovarian response of patients with hypogonadotropic hypogonadism (HH). DESIGN Observational retrospective cohort including infertile women with HH undergoing assisted reproductive treatment (ART). SETTING University-affiliated infertility center. PATIENT(S) Thirty-three women with HH who underwent ART between January 2007 and September 2018. The control group comprised 66 age-matched counterparts with tubal or male factor infertility. The patients with an abnormal karyotype, and those presenting primary or secondary amenorrhea due to other causes, were cautiously excluded. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The primary outcome was serum levels of anti-Müllerian hormone (AMH) and AFC. We also investigated whether HH impacts ovarian response and reproductive outcomes. RESULT(S) Although AFC was similar between groups, HH patients showed significantly higher AMH levels (4.6 ± 2.7 ng/mL vs. 3.0 ± 1.9, p = 0.010) and lower basal FSH and LH. While the HH group needed longer stimulation [13 days (11-26) vs. 10 (7-14), p < 0.001] and higher gonadotropin doses [2700 IU (825-6300) vs. 2100 (425-5000), p = 0.038 ], no significant differences were detected in either the number or maturity of retrieved oocytes, or in the fertilization rate, number of embryos transferred, implantation rate, clinical pregnancy rate and live birth rate per cycle. CONCLUSION(S) HH patients present higher AMH levels, but similar AFC. Despite requiring longer stimulation and higher gonadotropin doses, ovarian response and reproductive outcomes seem unaffected.

Similarities and differences in the reproductive phenotypes of women with congenital hypogonadotrophic hypogonadism caused by GNRHR mutations and women with polycystic ovary syndrome. Hum Reprod 2019; 34:137-147. [PMID: 30476149 DOI: 10.1093/humrep/dey339] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2018] [Accepted: 11/17/2018] [Indexed: 12/31/2022] Open
Abstract
STUDY QUESTION Does the phenotype of women with normosmic congenital hypogonadotrophic hypogonadism (nCHH) and pituitary resistance to GnRH caused by biallelic mutations in the GnRH receptor (GNRHR) (nCHH/bi-GNRHR) differ from that of women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER Women with nCHH/bi-GNRHR have variable pubertal development but nearly all have primary amenorrhea and an exaggerated LH response to GnRH stimulation, similar to that seen in women with PCOS. WHAT IS KNOWN ALREADY Women with nCHH/bi-GNRHR are very rare and their phenotype at diagnosis is not always adequately documented. The results of gonadotrophin stimulation by acute GnRH challenge test and ovarian features have not been directly compared between these patients and women with PCOS. STUDY DESIGN, SIZE, DURATION We describe the phenotypic spectrum at nCHH/bi-GNRHR diagnosis in a series of 12 women. Their reproductive characteristics and acute responses to GnRH were compared to those of 70 women with PCOS. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients and controls (healthy female volunteers aged over 18 years) were enrolled in a single French referral centre. Evaluation included clinical and hormonal studies, pelvic ultrasonography and GnRH challenge test. We also functionally characterized two missense GNRHR mutations found in two new consanguineous families. MAIN RESULTS AND THE ROLE OF CHANCE Breast development was highly variable at nCHH/bi-GNRHR diagnosis, but only one patient had undeveloped breasts. Primary amenorrhea was present in all but two cases. In untreated nCHH/bi-GNRHR patients, uterine height (UH) correlated (P = 0.01) with the circulating estradiol level and was shorter than in 23 nulliparous post-pubertal age-matched controls (P < 0.0001) and than in 15 teenagers with PCOS under 20-years-old (P < 0.0001) in which PCOS was revealed by primary amenorrhea or primary-secondary amenorrhea. Unexpectedly, the stimulated LH peak response in nCHH/bi-GNRHR patients was variable, and often normal or exaggerated. Interestingly, the LH peak response was similar to that seen in the PCOS patients, but the latter women had significantly larger mean ovarian volume (P < 0.001) and uterine length (P < 0.001) and higher mean estradiol (P < 0.001), anti-Müllerian hormone (AMH) (P = 0.02) and inhibin-B (P < 0.001) levels. In the two new consaguineous families, the affected nCHH/bi-GNRHR women carried the T269M or Y290F GNRHR missense mutation in the homozygous state. In vitro analysis of GnRHR showed complete or partial loss-of-function of the T269M and Y290F mutants compared to their wildtype counterpart. LIMITATIONS, REASONS FOR CAUTION The number of nCHH/bi-GNRHR patients reported here is small. As this disorder is very rare, an international study would be necessary to recruit a larger cohort and consolidate the phenotypic spectrum observed here. WIDER IMPLICATIONS OF THE FINDINGS In teenagers and young women with primary amenorrhea, significant breast and uterine development does not rule out CHH caused by biallelic GNRHR mutations. In rare patients with PCOS presenting with primary amenorrhea and a mild phenotype, the similar exaggerated pituitary LH responses to GnRH in PCOS and nCHH/bi-GNRHR patients could lead to diagnostic errors. This challenge test should therefore not be recommended. As indicated by consensus and guidelines, careful analysis of clinical presentation and measurements of testosterone circulating levels remain the basis of PCOS diagnosis. Also, analysis of ovarian volume, UH and of inhibin-B, AMH, estradiol and androgen circulating levels could help to distinguish between mild PCOS and nCHH/bi-GNRHR. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by the French National Research Agency (ANR) grant ANR-09-GENO-017 KALGENOPATH, France; and by the Italian Ministry of Education, University and Research (MIUR) grant PRIN 2012227FLF_004, Italy.

Abstract
INTRODUCTION Originally limited to the assessment of disorders of sex development, anti-Müllerian hormone (AMH) measurement has more recently been extended to several conditions affecting the reproductive axis in males and females. Follicle-stimulating hormone (FSH) regulation of gonadal function has been extensively studied, but its role on AMH production has been explored only recently. AREAS COVERED We addressed the relationship between FSH action on the gonads and the usefulness of AMH as a marker in conditions affecting the reproductive axis. EXPERT OPINION Sertoli cells are the most active cell population in the prepubertal testis. Serum AMH is an excellent marker of FSH action on Sertoli cell proliferation and function in patients with hypogonadotropic hypogonadism. Low serum AMH is expected to predict low sperm production and prompts initial FSH treatment followed by human chorionic gonadotropin (hCG) or luteinizing hormone (LH) addition. Gonadotropin treatment may be more effective if installed to mimic the postnatal activation stage of the hypothalamic-pituitary-testicular axis. In females, AMH secretion by small antral follicles is stimulated by FSH. Elevated AMH indicates increased follicle numbers and should be considered as a potential contraindication of gonadotropin treatment in infertile patients due to an increased risk of developing ovarian hyperstimulation syndrome.

Abstract
AIM To investigate the effectiveness of ovulation induction and intrauterine insemination (OI + IUI) in female patients with hypogonadotropic hypogonadism (HH), and to compare the outcomes of different stimulation protocols and cycle characteristics. MATERIAL AND METHODS The outcomes of OI + IUI treatments in patients with HH diagnosed between 2010 and 2018 were retrospectively evaluated. Cycles using recombinant (rec) luteinizing hormone (LH) or human menopausal gonadotropin (hMG) as LH sources were compared with each other. The cycle characteristics and pregnancy rates of the first cycles were compared with those of the second cycles in patients who underwent 2 or more cycles. RESULTS Of 104 patients diagnosed with World Health Organization type 1 anovulation, 99 were treated with hMG or rec LH + rec follicle-stimulating hormone (FSH) in a total of 220 cycles. The mean age of the study patients was 27.8 ± 4.6 years (range, 19-39 years). Rec FSH + rec LH was given in 37 cycles, and hMG was used in 183 cycles. The hormone values were as follows: FSH, 1.4 ± 1.6 mIU/mL; LH, 0.7 ± 1.2 mIU/mL; oestradiol, 13 (15.8 ± 12.0) pg/mL; and anti-Müllerian hormone, 2.1 (2.6 ± 1.2) ng/mL. A dominant follicle was observed in 85.7% of the first cycles and in 86.2% of the second cycles. The treatment lasted 17.2 ± 5.0 and 15.5 ± 3.8 days until the human chorionic gonadotropin (hCG) administration day in the first and second cycles, respectively, and the difference was statistically significant (p < 0.05). The cycle cancellation rate was 8.1% (n = 3) in cycles done using rec gonadotropins and 29% (n = 53) in patients stimulated with hMG, and the difference was statistically significant (p < 0.05). The pregnancy rates were 12.7% and 28.3% per cycle and per patient, respectively. The pregnancy rate in hCG-triggered patients (successful stimulation) was 17.1% per cycle in all patients. CONCLUSION OI with gonadotropins and IUI is a safe, efficient, and relatively cost-effective treatment option in patients with HH, yielding reasonable pregnancy rates per cycle and per patient. The use of rec FSH + rec LH facilitates cycle management but does not positively contribute to pregnancy rates and is more expensive than some other feasible options.

Abstract
The initiation and maintenance of reproductive capacity in humans is dependent on pulsatile secretion of the hypothalamic hormone GnRH. Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder that results from the failure of the normal episodic GnRH secretion, leading to delayed puberty and infertility. CHH can be associated with an absent sense of smell, also termed Kallmann syndrome, or with other anomalies. CHH is characterized by rich genetic heterogeneity, with mutations in >30 genes identified to date acting either alone or in combination. CHH can be challenging to diagnose, particularly in early adolescence where the clinical picture mirrors that of constitutional delay of growth and puberty. Timely diagnosis and treatment will induce puberty, leading to improved sexual, bone, metabolic, and psychological health. In most cases, patients require lifelong treatment, yet a notable portion of male patients (∼10% to 20%) exhibit a spontaneous recovery of their reproductive function. Finally, fertility can be induced with pulsatile GnRH treatment or gonadotropin regimens in most patients. In summary, this review is a comprehensive synthesis of the current literature available regarding the diagnosis, patient management, and genetic foundations of CHH relative to normal reproductive development.

Abstract
CONTEXT Mutations in the kisspeptin receptor (KISS1R) gene have been reported in a few patients with normosmic congenital hypogonadotropic hypogonadism (nCHH) (OMIM #146110). OBJECTIVES To describe a female patient with nCHH and a novel homozygous KISS1R mutation and to assess the role of kisspeptin pathway to induce an ovulation by GnRH pulse therapy. DESIGN, SETTING, AND INTERVENTION Observational study of a patient including genetic and kisspeptin receptor functions and treatment efficiency using a GnRH pump. MAIN OUTCOME MEASURE Response to pulsatile GnRH therapy. RESULTS A partial isolated gonadotropic deficiency was diagnosed in a 28-year-old woman with primary amenorrhea and no breast development. A novel homozygous c.953T>C variant was identified in KISS1R. This mutation led to substitution of leucine 318 for proline (p.Leu318Pro) in the seventh transmembrane domain of KISS1R. Signaling via the mutated receptor was profoundly impaired in HEK293-transfected cells. The mutated receptor was not detected on the membrane of HEK293-transfected cells. After several pulsatile GnRH therapy cycles, an LH surge with ovulation and pregnancy was obtained. CONCLUSION GnRH pulsatile therapy can induce an LH surge in a woman with a mutated KISS1R, which was previously thought to be completely inactivated in vivo.

Abstract
Congenital hypogonadotropic hypogonadism (CHH) and Kallmann syndrome (KS) are rare, related diseases that prevent normal pubertal development and cause infertility in affected men and women. However, the infertility carries a good prognosis as increasing numbers of patients with CHH/KS are now able to have children through medically assisted procreation. These are genetic diseases that can be transmitted to patients' offspring. Importantly, patients and their families should be informed of this risk and given genetic counseling. CHH and KS are phenotypically and genetically heterogeneous diseases in which the risk of transmission largely depends on the gene(s) responsible(s). Inheritance may be classically Mendelian yet more complex; oligogenic modes of transmission have also been described. The prevalence of oligogenicity has risen dramatically since the advent of massively parallel next-generation sequencing (NGS) in which tens, hundreds or thousands of genes are sequenced at the same time. NGS is medically and economically more efficient and more rapid than traditional Sanger sequencing and is increasingly being used in medical practice. Thus, it seems plausible that oligogenic forms of CHH/KS will be increasingly identified making genetic counseling even more complex. In this context, the main challenge will be to differentiate true oligogenism from situations when several rare variants that do not have a clear phenotypic effect are identified by chance. This review aims to summarize the genetics of CHH/KS and to discuss the challenges of oligogenic transmission and also its role in incomplete penetrance and variable expressivity in a perspective of genetic counseling.

Hypothalamic-Pituitary-Ovarian Axis Reactivation by Kisspeptin-10 in Hyperprolactinemic Women With Chronic Amenorrhea. J Endocr Soc 2017; 1:1362-1371.

Abstract
Context: Hyperprolactinemia-induced hypogonadotropic amenorrhea (hPRL-HA) is a major cause of hypothalamic gonadotrophin-releasing hormone (GnRH) deficiency in women. In hyperprolactinemic mice, we previously demonstrated that hypothalamic kisspeptin (Kp) expression was diminished and that Kp administration restored hypothalamic GnRH release, gonadotropin secretion, and ovarian cyclicity, suggesting that Kp neurons could also play a role in hPRL-HA. Objective: To study the effect of Kp-10 on the gonadotropic-ovarian axis in women with hPRL-HA. Patients: Two women (32 and 36 years old) with chronic hPRL-HA (prolactin: between 94 and 102 and 98 and 112 ng/mL, respectively) caused by cabergoline-resistant microprolactinomas. Interventions: Cabergoline was discontinued 6 months before inclusion. Blood samples were taken every 10 minutes for 12 hours during 2 consecutive days to evaluate luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion. Serum estradiol (E2), testosterone (T), and inhibin B (IB) levels were also measured. Vehicle or Kp-10 (1.5 μg/kg/h) was infused intravenously for 12 hours. Results: Kp-10 induced a significant increase in LH and FSH levels and increased LH pulses. E2, T, and IB serum levels were also significantly increased. Conclusions: In this exploratory study, we demonstrated that administration of Kp-10 reactivated gonadotropin secretion in women with hPRL-HA and increased ovarian activity. Our data suggest that, as in rodents, GnRH deficiency in hPRL-HA is also mediated by an impairment of hypothalamic Kp secretion. Kp-10 or its analogues could have therapeutic application as an alternative approach to restore ovarian function and fertility in women with hPRL-HA resistant to dopamine agonists and in whom pituitary surgery is not possible.

Abstract
Members of the transforming growth factor-beta (TGF-beta) superfamily are key regulators of various physiological processes. Anti-Müllerian hormone (AMH) which is also commonly known as Müllerian-inhibiting substance (MIS) is a member of the TGF-beta superfamily and an important regulator of reproductive organ differentiation and ovarian follicular development. While AMH has been used for diagnostic purposes as a biomarker for over 15 years, new potential therapeutic applications of recombinant human AMH analogues are now emerging as pharmacologic agents in reproductive medicine. Therapeutic uses of AMH in gonadal tissue may provide a unique opportunity to address a broad range of reproductive themes, like contraception, ovulation induction, onset of menopause, and fertility preservation, as well as specific disease conditions, such as polycystic ovarian syndrome (PCOS) and cancers of the reproductive tract. This review explores the most promising therapeutic applications for a novel class of drugs known as AMH analogues with agonist and antagonist functions.
