BACKGROUND: The increase in serum estradiol (E2) concentrations during the follicular phase becomes the index of oocyte maturation in vivo. When ovarian stimulation is performed to hypogonadotropic hypogonadism (HH) patients with only follicle stimulating hormone (FSH), proper increase in serum E2 concentrations is not observed. Even if oocytes are obtained, which usually have low fertilization rate. In this report, we would like to present an unique case, in which under low E2 concentrations and without luteinizing hormone (LH) administration, numerous mature oocytes could be obtained and a healthy baby delivered...

DAX1 (NR0B1) is an orphan nuclear receptor, which plays an important role in development and function of the adrenal glands and gonads. Mutations in DAX1 cause X-linked adrenal hypoplasia congenita (X-linked AHC), which is characterized by adrenal insufficiency (AI) and hypogonadotropic hypogonadism (HHG). Affected boys present with adrenal failure usually in childhood and, later in life, with delayed puberty. However, patients with a late-onset form of X-linked AHC have also been described in the past years...

Hypogonadotropic hypogonadism (HH) is common and occurs prematurely in HIV-infected men. However, HH with very low testosterone has not been described. Three men with normal pubertal development and HIV1 diagnosis at the ages of 22, 34 and 35 years. All complained of decreased libido, anejaculation and erectile dysfunction thirteen years, six months and one year after HIV diagnosis, respectively. Two had depressive syndrome and two were treated with antiretroviral therapy. Laboratory tests revealed isolated HH in all...

In daily practice, clinicians are often confronted with obese type 2 diabetes mellitus (T2DM) patients for whom the treatment plan fails and who show an inadequate glycemic control and/or no sustainable weight loss. Untreated hypogonadism can be the reason for such treatment failure. This case describes the profound impact testosterone therapy can have on a male hypogonadal patient with metabolic syndrome, resulting in a substantial and sustained loss of body weight, pronounced improvement of all critical laboratory values and finally complete remission of diabetes...

Cardiovascular disease is the leading cause of death in both women and men. Its pathogenesis is multifactorial, with sex hormones playing an important role. Androgens have both direct and indirect effects on the vasculature. This review summarizes evidence on the association of both endogenous and exogenous androgens with subclinical and overt cardiovascular disease in women and men. Concerning women, both high and low levels of endogenous androgens have been associated with cardiovascular disease, while other studies have reported no association...

BACKGROUND: Congenital hypogonadotropic hypogonadism (CHH) is classified as Kallmann syndrome (KS) with anosmia/hyposmia or normosmic (n)CHH. Here, we investigated the genetic causes and phenotype-genotype correlations in Japanese patients with CHH. METHODS: We enrolled 22 Japanese patients with CHH from 21 families (18 patients with KS and 4 with nCHH) and analyzed 27 genes implicated in CHH by next-generation and Sanger sequencing. RESULTS: We detected 12 potentially pathogenic mutations in 11 families, with three having a mutation in ANOS1 (X-linked recessive); three and four having a mutation in FGFR1 and CHD7, respectively (autosomal dominant); and one having two TACR3 mutations (autosomal recessive)...

Patients with gender dysphoria are offered cross-sex hormone therapy and sex reassignment surgery to achieve the transition between the sex assigned at birth and gender identity. According to international guidelines, cross-sex hormone therapy in trans-women should lead to a psychologically and physiologically healthy body with feminized serum hormone levels, resulting in suppression of spermatogenesis. However, in a recently published multi-center study, we discovered a high proportion of patients with male serum hormone levels and qualitatively intact spermatogenesis on the day of sex reassignment surgery...

Cognitive function and testosterone level of men decline concurrently with aging. Low testosterone levels are associated with higher risk of Alzheimer's disease and mild cognitive impairment in men. There are continuous debates on whether this relationship is casual or causal. This paper aims to summarize the current evidence on the association between testosterone level and cognitive function in elderly men. The presence of testosterone, androgen receptor and its responsive genes hint that testosterone has biological functions in the central nervous system...

OBJECTIVE: The pituitary production of human chorionic gonadotropin (hCG) can cause false-positive results during or after germ cell tumor (GCT) treatment. Because hypogonadism leads to pituitary hCG production, testosterone administration test (TAT) has been recommended for pituitary hCG diagnosis. However, little is known about its efficacy for the discrimination of pituitary hCG as detected by currently used hCG assays in treatment of GCT. We conducted a retrospective multicenter study to determine the usefulness of TAT...

INTRODUCTION: This paper presents a rare event of genital self-mutilation and few cases are reported in the literature. CASE DESCRIPTION: We report on a patient who performed partial self-penectomy 18 months after bilateral testicular amputation, as a form of self-mutilation. CONCLUSIONS: The main hypotheses to explain the recurrence of self-mutilation would be hypogonadism.

Klinefelter syndrome (KS) is a chromosomal disorder affecting males, with the typical karyotype of 47,XXY due to a supernumerary X chromosome, which causes progressive testicular failure resulting in androgen deficiency and infertility. Despite it being the most common sex chromosomal disorder, its diagnosis is easily missed. In addition to its classical clinical features of tall stature, gynaecomastia, small testes, and symptoms and signs of hypogonadism including infertility, KS is also often associated with neurocognitive, behavioural and psychiatric disorders...

Background Patients with thalassemia major (TM) require repeated blood transfusions, which leads to accumulation of iron in a wide variety of tissues. Accumulation of iron in the pituitary gland can lead to irreversible hypogonadotropic hypogonadism (HH) in this group of patients. Purpose To investigate the reliability of pituitary-R2 as a marker to estimate the extent of pituitary iron load by comparing the pituitary magnetic resonance imaging (MRI) findings with hepatic iron load and serum ferritin levels...

INTRODUCTION: Growth hormone (GH) and insulin-like growth factor-I (IGF-1) have pleiotropic effects on the skeleton throughout the lifespan by influencing bone formation and resorption. Despite these positive effects on skeletal metabolism, in presence of GH and IGF-1 excess, bone turnover increases excessively leading to deterioration of bone microarchitecture and high risk of fragility fractures, thereby impairing quality of life. EVIDENCE ACQUISITION: Coexistent hypogonadism, diabetes mellitus, hypovitaminosis D, hyperparathyroidism and over-replacement with glucocorticoids impair bone framework, however, the effects of acromegaly on bone mineral density (BMD) are still controversial and despite normalization of bone turnover after treatment, the risk for fractures remains increased...

INTRODUCTION: Idiopathic hypogonadotrophic hypogonadism (IHH) with an olfactory deficit is defined as Kallmann syndrome (KS) and is distinct from normosmic IHH. OBJECTIVE: Because olfactory perception not only consists of orthonasally gained impressions but also involves retronasal olfactory function, in this study we decided to comprehensively evaluate both retronasal and orthonasal olfaction in patients with IHH. METHODS: This case-control study included 31 controls and 45 IHH patients...

OBJECTIVE Surgery is generally the first-line therapy for acromegaly. For patients with residual or recurrent tumors, several treatment options exist, including repeat surgery, medical therapy, and radiation. Reoperation for recurrent acromegaly has been associated with poor results, with hormonal control usually achieved in fewer than 50% of cases. Extended endonasal endoscopic approaches (EEAs) may potentially improve the results of reoperation for acromegaly by providing increased visibility and maneuverability in parasellar areas...
