The role and implication of platelet‐rich plasma in male factor infertility: A systematic review of human studies

open access: yesAndrology, EarlyView.
Abstract Background Cryopreservation causes sperm injury and the success of surgical sperm retrieval (SSR) for azoospermic men is just over half depending on the cause of azoospermia. The role of autologous platelet‐rich plasma (PRP) in male factor infertility (MFI) is unclear. Objective To conduct a systematic review of the role of PRP in MFI focusing

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

open access: yesAndrology, 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

open access: yesAndrology, 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

open access: yesAndrology, 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.

The role of iron in normal and impaired testicular function

open access: yesAndrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...
