Effects of FSH on the expression of receptors for oocyte-secreted factors and members of the EGF-like family during in vitro maturation in cattle

, 2013
FSH induces expansion of bovine cumulus-oocyte complexes (COCs) in cattle, which can be enhanced by oocyte-secreted factors (OSFs). In this study it was hypothesised that FSH stimulates COC expansion in part from direct stimulation of the epidermal ...

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.

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.

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

Andrology, EarlyView.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in

Characterization of the somatostatin system in tilapia: implications for growth and reproduction

Frontiers in Endocrinology
Somatostatin (SST) plays diverse physiological roles in vertebrates, particularly in regulating growth hormone secretion from the pituitary. While the function of SST as a neuromodulator has been studied extensively, its role in fish and mammalian ...

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 ...

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 ...
