Reproductive Phenotypes in Men With Acquired or Congenital Hypogonadotropic Hypogonadism: A Comparative Study.

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.

Project description:IntroductionCongenital hypogonadotropic hypogonadism (CHH) is a rare, genetic, reproductive endocrine disorder characterized by absent puberty and infertility. Limited information is available on the psychosocial impact of CHH and psychosexual development in these patients.AimThe aim of this study was to determine the impact of CHH on psychosexual development in men on long-term treatment.MethodsA sequential mixed methods explanatory design was used. First, an online survey (quantitative) was used to quantify the frequency of psychosexual problems among CHH men. Second, patient focus groups (qualitative) were conducted to explore survey findings in detail and develop a working model to guide potential nursing and interdisciplinary interventions.Main outcome measuresPatient characteristics, frequency of body shame, difficulty with intimate relationships, and never having been sexually active were assessed. Additionally, we collected subjective patient-reported outcomes regarding the impact of CHH on psychological/emotional well-being, intimate relationships, and sexual activity.ResultsA total of 101 CHH men on long-term treatment (>1 year) were included for the analysis of the online survey (mean age 37 ± 11 years, range 19-66, median 36). Half (52/101, 51%) of the men had been seen at a specialized academic center and 37/101 (37%) reported having had fertility-inducing treatment. A high percentage of CHH men experience psychosexual problems including difficulty with intimate relationships (70%) and body image concerns/body shame (94/101, 93%), and the percentage of men never having been sexually active is five times the rate in a reference group (26% vs. 5.4%, P < 0.001). Focus groups revealed persisting body shame and low self-esteem despite long-term treatment that has lasting impact on psychosexual functioning.ConclusionsCHH men frequently experience psychosexual problems that pose barriers to intimate relationships and initiating sexual activity. These lingering effects cause significant distress and are not ameliorated by long-term treatment. Psychosexual assessment in CHH men with appropriate psychological support and treatment should be warranted in these patients. Dwyer AA, Quinton R, Pitteloud N, and Morin D.

Project description:BackgroundAfter hormonal replacement therapy (HRT) including androgen replacement or sequential therapy of estrogen and progesterone, The combination of human chorionic gonadotropin (hCG) and human menopausal gonadotropin (hMG) and pulsatile GnRH, is not sufficient to produce sufficient gametes in some patients with Congenital hypogonadotropic hypogonadism (CHH). A Systematic review and meta-analysis was performed to determine that assisted reproductive techniques (ART) can effectively treat different causes of infertility.MethodsTo determine the effect of ART on fertility of CHH patients and investigate whether outcomes are similar to infertility due to other causes, we conducted a systematic review and meta-analysis of retrospective trials. Clinical trials were systematically searched in Medline, Embase, and the Cochrane central register of controlled trials databases. The keywords and major terms covered "hypogonadotropic hypogonadism", "kallmann syndrome", "assisted reproductive techniques", "intrauterine insemination", "intracytoplasmic sperm injection", "testicular sperm extraction", "in vitro fertilization", "embryo transplantation" and "intra-Fallopian transfer".ResultsA total of 388 pregnancies occurred among 709 CHH patients who received ART (effectiveness 46, 95% confidence interval 0.39 to 0.53) in the 20 studies we included. The I2 in trials assessing overall pregnancy rate (PR) per embryo transfer (ET) cycle was 73.06%. Similar results were observed in subgroup analysis by different gender. Regression indicates pregnancy rate decreases with increasing age. Fertilization, implantation and live birth rates (72, 36 and 40%) showed no significant differences as compared to infertility due to other causes.ConclusionsDespite CHH patients usually being difficult to generate gametes, their actual chances of fertility are similar to subjects with other non-obstructive infertility. ART is a suitable option for CHH patients who do not conceive after long-term gonadotropin treatment.

Project description:Congenital hypogonadotropic hypogonadism (CHH) can be divided into Kallmann syndrome (KS) and normosmic HH (nHH). The clinical and genetic characteristics of CHH have been studied in adults, but less in pre-adults. The medical records of patients with CHH in our gonad disease database from 2008 to 2020 were evaluated. In total, 125 patients aged 0 to 18 years were enrolled in our study. KS patients had a higher incidence of micropenis compared with nHH (86.2% vs. 65.8%, p=0.009), and 7 patients (5.6%) had hypospadias. Among the 39 patients with traceable family history, delayed puberty, KS/nHH, and olfactory abnormalities accounted for 56.4%, 17.9%, and 15.4%, respectively. In total, 65 patients completed the hCG prolongation test after undergoing the standard hCG test, and the testosterone levels of 24 patients (22.9%) were still lower than 100 ng/dL. In 77 patients, 25 CHH-related genes were identified, including digenic and trigenic mutations in 23 and 3 patients, respectively. The proportion of oligogenic mutations was significantly higher than that in our previous study (27.7% vs. 9.8%). The most common pathogenic genes were FGFR1, PROKR2, CHD7 and ANOS1. The incidence rate of the genes named above was 21.3%, 18.1%, 12.8% and 11.7%, respectively; all were higher than those in adults (<10%). Most mutations in CHH probands were private, except for W178S in PROKR2, V560I in ANOS1, H63D in HS6ST1, and P191L and S671L in IL17RD. By analyzing family history and genes, we found that both PROKR2 and KISS1R may also be shared between constitutional delay of growth and puberty (CDGP) and CHH. L173R of PROKR2 accounts for 40% of the CHH population in Europe and the United States; W178S of PROKR2 accounts for 58.8% of Chinese CHH patients. Micropenis and cryptorchidism are important cues for CHH in children. They are more common in pediatric patients than in adult patients. It is not rare of Leydig cell dysfunction (dual CHH), neither of oligogenic mutations diagnosed CHH in children. Both PROKR2 and KISS1R maybe the potential shared pathogenic genes of CDGP and CHH, and W178S in PROKR2 may be a founder mutation in Chinese CHH patients.
