Gender‐affirming hormone therapy: Effect on semen quality and use of fertility preservation

Andrology, Volume 14, Issue 1, Page 322-330, January 2026.
Abstract Fertility preservation (FP) is a fundamental part of gender care. Gender‐affirming hormone therapy (GAHT) involves the use of drugs that could be potential risk factors for fertility. Therefore, FP is recommended before beginning the gender‐affirmation process.

Effects of neonatal hypothyroidism on testicular development and undifferentiated spermatogonia in prepubertal rats

Andrology, Volume 14, Issue 1, Page 196-209, January 2026.
Abstract Background Thyroid hormones play a key role in testicular development, particularly in the regulation of Sertoli cell proliferation and differentiation. While congenital hypothyroidism is common and treatable, the effects of thyroid hormone insufficiency on early testicular development during the neonatal period remain unclear. Objectives This

The Overlooked Threat of Global Warming on Elasmobranch Fertility

Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.
ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

Impact of FSH‐Induced Ovarian Stimulation on Oocyte Recovery and In Vitro Embryo Production in the Red Sindhi Cows

Reproduction in Domestic Animals, Volume 61, Issue 1, January 2026.
ABSTRACT Follicle‐stimulating hormone (FSH) plays an important role in regulating reproductive events, particularly follicular development and oocyte competence acquisition. Some studies using FSH protocols in zebu cattle were performed, but data regarding its application in the Red Sindhi breed are scarce and therefore warranted. In this context, this
