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.

Vitamin D levels and biomarkers of male fecundity: A study from the Danish National Birth Cohort

Andrology, EarlyView.
Abstract Background Vitamin D is metabolised throughout the male reproductive system, suggesting a direct regulatory role of vitamin D in male reproduction. Objectives To investigate the association between plasma vitamin D levels at sperm ejaculation and during spermatogenesis and biomarkers of male fecundity in young men.

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.

Testis‐Specific PDHA2 Is Required for Proper Meiotic Recombination and Chromosome Organisation During Spermatogenesis

Cell Proliferation, EarlyView.
PDHA2, a testis‐specific subunit of pyruvate dehydrogenase, is required for the conversion of pyruvate to acetyl‐CoA. Its absence results in decreased acetyl‐CoA and precursors for metabolites and energy during spermatogenesis. This results in decreased histone acetylation, defective chromosome structure and moderately reduced crossovers, ultimately ...
