Novel role for anti-Müllerian hormone in the regulation of GnRH neuron excitability and hormone secretion

Nature Communications, 2016
Anti-Müllerian hormone (AMH) plays a role in sexual differentiation and gonadal function, but extra-gonadal effects of AMH are not known. Here Cimino et al.

The 1994 Stevenson Award Lecture. Follicle-stimulating hormone and luteinizing hormone: a tale of two gonadotropins

, 1995
Although most gonadotropes synthesize both luteinizing hormone and follicle-stimulating hormone, the transcription, content, and secretion rates of the two gonadotropins can be separated.

Association Between FTO rs1558902 Polymorphism, Age‐Related Hypogonadism, and Central Obesity in Japanese Men

Andrology, EarlyView.
ABSTRACT Background Obesity and low testosterone levels are closely interconnected, with the FTO gene being the most robust genetic determinant of body mass index (BMI). However, whether this primary genetic driver of obesity directly influences the hypothalamic‐pituitary‐testicular (HPT) axis remains unclear.

Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

Andrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

Andrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

A drop in serum estradiol levels during GnRH antagonist cotreatment in cycles stimulated with gonadotropins is associated with lower cumulative live birth rates

Frontiers in Endocrinology
Over the last decades, the gonadotropin-releasing hormone (GnRH) antagonist protocol has become widely used for prevention of premature luteinizing hormone surge during ovarian stimulation with exogenous gonadotropins.

Intrauterine Growth and Male Reproductive Health: A Follow‐up Study From the Danish National Birth Cohort

Andrology, EarlyView.
ABSTRACT Background Reduced intrauterine growth might affect male reproductive health later in life, however, existing research remain inconclusive. Objectives To investigate the association between placental weight and birthweight Z‐scores and semen characteristics, testes volume, and reproductive hormone levels in young men.
