INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2023; 17:57-60. [PMID: 36617204 PMCID: PMC9807897 DOI: 10.22074/ijfs.2022.540499.1201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Indexed: 01/09/2023]
Abstract
BACKGROUND Idiopathic hypogonadotropic hypogonadism (IHH) is a medical condition where there is a deficiency or insensitivity of gonadotropin-releasing hormone (GnRH) without a known cause. Not only are the sexual characteristics of a person affected by this condition but also are the psychological and physical development, thus necessitating its early recognition and treatment. This research was carried out to identify the laboratory parameters and to present symptoms of the patients with complaints of IHH. MATERIALS AND METHODS This retrospective, center, single-center, cross-sectional study was carried out in Aga Khan University from December 2000 until December 2020 on the patients that presented to the clinic with IHH. The patients included in the study were those that presented with hypogonadism, a low concentration of sex steroid hormone, and an abnormal gonadotropin level without any expansive pituitary or hypothalamic lesion. RESULTS Seventy nine patients presenting with IHH were included with their mean age of 24.2 ± 7.5 years. Of these, 64 (81.0%) had genital atrophy, 50 (63.6%) showed an absence of secondary sexual characteristics, 53 (67.1%) complained of infertility, 44 (55.7%) had not shown signs of puberty, 52 (65.8%) had erectile dysfunction, 46 (58.2%) had a decrease in libido, 11(13.9%) had a previous familial history, 24 (30.3%) had gynecomastia, 9 (11.4%) had non-descended testes, and 6 (7.6%) had anosmia. These patients had serum testosterone, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels of 26.3 ± 60, 1.3 ± 2.4, and 2.7 ± 5.0 (IU/L), respectively. CONCLUSION Thus, it can be stated that small genitalia is the most common complaint among patients with IHH, followed by infertility and lack of secondary sexual characteristics. The testosterone level in serum is also found to be low among these patients.

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 Lymphopenia is a key feature for adult patients with coronavirus disease 2019 (COVID-19), while it is rarely observed in children. The underlying mechanism remains unclear. METHODS Immunohistochemical and flow cytometric analyses were used to compare the apoptotic rate of T cells from COVID-19 adults and children and apoptotic responses of adult and child T cells to COVID-19 pooled plasma. Biological properties of caspases and reactive oxygen species were assessed in T cells treated by COVID-19 pooled plasma. RESULTS Mitochondria apoptosis of peripheral T cells were identified in COVID-19 adult patient samples, but not in the children. Furthermore, increased TNF-α and IL-6 in COVID-19 plasma induced mitochondria apoptosis and caused DNA damage by elevating reactive oxygen species levels of the adult T cells. However, the child T cells showed tolerance to mitochondrial apoptosis due to mitochondria autophagy. Activation of autophagy could decrease apoptotic sensitivity of the adult T cells to plasma from COVID-19 patients. CONCLUSIONS Our results indicated that the mitochondrial apoptosis pathway was activated in T cells of COVID-19 adult patients specifically, which may shed light on the pathophysiological difference between adults and children infected with SARS-CoV-2.

Abstract
OBJECTIVE We aimed to analyse FGFR1 rare variants in a series of Chinese congenital hypogonadotropic hypogonadism (CHH) patients. In addition, we intended to understand the clinical characteristics and the response to treatment of CHH patients with FGFR1 rare variants. PATIENTS AND METHODS A total of 357 CHH patients were recruited at Peking Union Medical College Hospital. We used Sanger sequencing to analyse FGFR1 gene. In silico analysis was carried out to study the pathogenicity of novel missense variants. The clinical, endocrinological and therapeutic effects from patients carrying FGFR1 rare variants were analysed retrospectively. RESULTS Thimissense mutations.rty patients in this series were found to harbour 29 FGFR1 rare variants, with 8 recurrent and 21 novel variants. After comprehensive analysis, 18 out of 21 novel variants were classified as likely pathogenic (LP) ones. These variants are widely spread throughout the FGFR1 gene and almost all FGFR1 functional domains, which exhibited no hot spot. Cryptorchidism, cleft palate and dental abnormality incidence in this CHH series that possessed FGFR1 LP variants were approximately 38.5%, 7.6% and 3.8%, respectively. Among patients who accepted the fertility-promoting treatment, 8 out of 10 patients succeeded in spermatogenesis. CONCLUSIONS Eighteen novel LP variants were found to expand the spectrum of FGFR1 rare variants. In CHH patients possessing FGFR1 variants, we found that the rate of spermatogenesis was high following fertility-promoting therapy and the existence of cryptorchidism may represent the underlying factors which affect spermatogenesis.

Abstract
Idiopathic hypogonadotropic hypogonadism (IHH) refers to a family of genetic disorders that affect the production and/or action of gonadotropic-releasing hormone, resulting in reduced serum levels of sex steroids. This condition has a prevalence of 1-10 cases/100 000 births and is characterised by the absence of spontaneous pubertal development. In women, the condition is characterised by the onset of normal adrenarche, with the absence of thelarche and menarche. Pubertal induction for breast development and uterine growth with oestradiol, and sequential maintenance of a normal menstrual cycle and adequate oestrogen for bone health, with an oestrogen and progesterone, is considered first-line treatment. Pregnancy can be achieved in patients who have received and responded to treatment with ovulation induction with exogenous gonadotrophins. Advances in genetic testing have led to increased research and understanding of the underlying genetics of IHH with gene mutations described in up to 50% of all IHH cases.

Abstract
RNA polymerase III (POLR3)-related leukodystrophy is an autosomal recessive form of leukodystrophy caused by homozygous or compound heterozygous mutations of the RNA polymerase III subunit genes, including subunit A (POLR3A). With respect to the manifestation triad, hypomyelination, hypodontia, and hypogonadotropic hypogonadism, it is also known as 4H leukodystrophy. Here, we report a 41-year-old woman of POLR3-related leukodystrophy by carrying compound heterozygous pathogenic variants of c.2554A>G (p.M852V) and c.2668G>T (p.V890F) in the POLR3A gene. She was amenorrheic and became a wheelchair user from the age of 15 years and suffered from multiple episodes of pathologic fractures, starting with a subtrochanteric fracture of the right femur after a tonic seizure at age 30 years. Head magnetic resonance imaging demonstrated hypomyelination and atrophies of the cerebellum, brainstem, and corpus callosum. Laboratory examination revealed a marked decrease of gonadotropins and estrogen, low bone density, and high bone resorption markers. Administration of anti-receptor activator of nuclear factor kappa-B ligand monoclonal antibody restored bone resorption markers to a normal level and prevented further pathological bone fractures. Our case emphasizes that osteoporosis should be recognized as a potential but serious complication in POLR3-related leukodystrophy. It may be feasible to prevent pathologic fractures by intensive osteoporosis therapy after endocrinological examinations and evaluation of bone metabolism.

Abstract
Puberty, which in humans is considered to include both gonadarche and adrenarche, is the period of becoming capable of reproducing sexually and is recognized by maturation of the gonads and development of secondary sex characteristics. Gonadarche referring to growth and maturation of the gonads is fundamental to puberty since it encompasses increased gonadal steroid secretion and initiation of gametogenesis resulting from enhanced pituitary gonadotropin secretion, triggered in turn by robust pulsatile GnRH release from the hypothalamus. This chapter reviews the development of GnRH pulsatility from before birth until the onset of puberty. In humans, GnRH pulse generation is restrained during childhood and juvenile development. This prepubertal hiatus in hypothalamic activity is considered to result from a neurobiological brake imposed upon the GnRH pulse generator resident in the infundibular nucleus. Reactivation of the GnRH pulse generator initiates pubertal development. Current understanding of the genetics and physiology of the brake will be discussed, as will hypotheses proposed to account for timing the resurgence in pulsatile GnRH and initiation of puberty. The chapter ends with a discussion of disorders associated with precocious or delayed puberty with a focus on those with etiologies attributed to aberrant GnRH neuron anatomy or function. A pediatric approach to patients with pubertal disorders is provided and contemporary treatments for both precocious and delayed puberty outlined.

Abstract
BACKGROUND Congenital hypogonadotropic hypogonadism (CHH) is a rare genetically heterogeneous disorder. We aimed to determine the prevalence and pathogenesis of NECL2 (Nectin-like molecule 2) variants in a cohort of female patients with CHH. METHODS We sequenced and determined the prevalence of NECL2 variants in 68 female patients with CHH and 243 healthy controls collected from an academic medical center. Further cellular and animal studies were performed to verify the pathogenicity of the mutations. Necl2 knockout female mice were generated, and their puberty development was observed. RESULTS A novel NECL2 variant (c.1052_1060del, p.Thr351_Thr353del) was detected in 4 of 68 (5.9%) patients with CHH. Its prevalence was significantly higher in CHH patients than in healthy controls (0%). At the cellular level, the necl2 variant leads to a decrease in gonadotropin-releasing hormone. In animal models, we found that the Necl2 protein was expressed in the hypothalamus, especially in the ventromedial hypothalamic nucleus of mice. Necl2 knockout female mice showed delayed puberty and an irregular estrous cycle, consistent with CHH patient phenotypes. CONCLUSIONS Our findings predict that NECL2 may be a new candidate gene for CHH and that the NECL2 protein plays a critical role in the progression of puberty development.

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.

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.

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.
