Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

Andrology, EarlyView.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,

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

Andrology, EarlyView.
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

Lycium barbarum polysaccharides enhance testicular spermatogenesis in d‐galactose‐induced aging rats via calcium signaling

Andrology, EarlyView.
Abstract Background Lycium barbarum polysaccharide (LBP) has long been recognized as having a wide range of beneficial properties for improving proliferation. However, the protective effects and specific mechanisms of d‐galactose‐induced testicular dysfunction in reproductively senescent rats are not fully understood.

The Oxytocin Receptor in Spermatozoa May Originate From Both Spermatogenesis and Epididymal Maturation, and Regulates Capacitation

Andrology, EarlyView.
Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...
