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.

Feminizing Therapy in People With Klinefelter Syndrome and Gender Incongruence: Considerations for Treatment Without Testosterone Blockers

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS; 47, XXY) usually involves male sex development and gender identity. Small studies suggest gender incongruence may be more common in KS, but feminizing gender‑affirming hormone therapy in this group has been scarcely reported.

Machine Learning‐Based Prediction of Sperm Retrieval Outcomes in Patients With Klinefelter Syndrome: A Multicenter Study With External Validation

Andrology, EarlyView.
ABSTRACT Background The Klinefelter syndrome is a common genetic cause of male infertility, and testicular sperm extraction (TESE) enables sperm retrieval in a subset of affected patients. However, predicting TESE success remains challenging due to the heterogeneous clinical and endocrinological presentation of the Klinefelter syndrome.

The Bidirectional Association Between MASLD and Male Hypogonadism: An Updated Meta‐Analysis

Andrology, EarlyView.
ABSTRACT Background Metabolic dysfunction‐associated steatotic liver disease (MASLD) and male hypogonadism are increasingly prevalent, metabolically interrelated conditions. Testosterone (T) deficiency has been implicated in hepatic lipid dysregulation, insulin resistance, and visceral adiposity, whereas MASLD may impair the hypothalamic–pituitary ...

Advanced glycation end products interfere in luteinizing hormone and follicle stimulating hormone signaling in human granulosa KGN cells

, 2018
Advanced glycation end products accumulate in the ovarian granulosa-cell layer of women with polycystic ovarian syndrome. Taken that the MAPK/ERK-pathway is a key regulator of oocyte maturation and function, consisting the main pathway used by the ...

Receptors for luteinizing hormone-releasing hormone.

, 1978
Antisera to luteinizing hormone-releasing hormone (LH-RH) confer on Araldite sections of occasional rat pituitaries moderate immunocytochemical staining to the large secretory granules of gonadotrophs. Treatment of the sections with LH-RH before anti-LH-

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.

Sex Steroids Measurement by Mass Spectrometry in Hypogonadal Men in a Real‐World Setting: Serum Estradiol (E2) and E2 to Total Testosterone Ratio Do Not Differ Between Patients With Klinefelter Syndrome and Non‐Klinefelter Syndrome Hypogonadism

Andrology, EarlyView.
ABSTRACT Background Traditionally, Klinefelter syndrome (KS) was considered a clinical condition associated with hyperestrogenism. Aim To compare circulating sex steroids, particularly estrogens, in a cohort of KS and non‐KS hypogonadal men. Materials and Methods A cohort of hypogonadal men, treated and untreated, was prospectively enrolled in a real ...

Maternal Consumption of Artificially Sweetened Beverages in Pregnancies and Biomarkers of Fecundity in Adult Sons

Andrology, EarlyView.
ABSTRACT Introduction Maternal intake of artificial sweeteners in beverages (ASB) during pregnancy may have a programming effect on offspring health, including biomarkers of male fecundity. Objective We investigated whether maternal intake of ASB during pregnancy was associated with biomarkers of male fecundity in adult sons.

Diabetes‐Induced Testicular Injury: Potential Protective Roles of Curcumin, Garcinia kola, and Momordica charantia in Rats

Andrology, EarlyView.
ABSTRACT Background Diabetes mellitus (DM) induces multifaceted cellular and structural alterations in the male reproductive system, thereby predisposing to infertility. Objectives This study aimed to evaluate the morphological, stereological, biochemical, histopathological, and ultrastructural changes induced by DM in testicular tissue, and to ...
