Season of birth and variations in male reproductive health: A population‐based cohort study

Andrology, EarlyView.
Abstract Background Season of birth has been associated with various later reproductive health outcomes in women, but little is known on the potential associations in men. Objectives To investigate the association between season of birth and semen characteristics, testes volume and reproductive hormone levels in young men.

Pharmacogenetics of follicle‐stimulating hormone action in the male

Andrology, EarlyView.
Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.

Comparative efficacy of varicocelectomy and intrauterine insemination in varicocoele patients with mild semen abnormalities: An observational study

Andrology, EarlyView.
Abstract Background Varicocoele is a common cause of male infertility, affecting spermatogenesis through increased testicular temperature, venous stasis, and oxidative stress. Microsurgical subinguinal varicocelectomy improves semen quality, whereas intrauterine insemination is widely used for mild male factor infertility.

Moderate Day‐To‐Day Variation in First‐Morning Urine Total Luteinizing Hormone Levels Supports the Use of a Single Determination to Identify Imminent Puberty

Clinical Endocrinology, Volume 102, Issue 5, Page 578-588, May 2025.
ABSTRACT Objectives We aimed to study the daily variation in first‐morning urinary total luteinizing hormone (U‐LH) determination and validate it as a noninvasive method for analyzing age‐ and pubertal stage‐related changes in LH immunoreactivity (LH‐ir) levels to predict imminent onset of central puberty.

Determination of Androgen Bioactivity by an In Vitro Assay During Pubertal Transition in Healthy Boys

Clinical Endocrinology, EarlyView.
ABSTRACT Objective To describe the bioactivity of circulating androgens during pubertal transition as determined by an in vitro bioassay assessing androgen receptor (AR) activation, and to compare these findings with circulating concentrations of total testosterone (total T) measured by LC‐MS/MS.
