To participate in sperm–oocyte fusion, spermatozoa need to be motile. In the testes,
spermatozoa are immotile, although these gametes acquire the capacity for motility during …

Mitogen-activated protein kinases (MAPKs) represent widely expressed and evolutionarily
conserved proteins crucial for governing signaling pathways and playing essential roles in …

Mammalian spermatozoa are not mature after ejaculation and must undergo additional
functional and structural changes within female reproductive tracts to achieve subsequent …

To achieve fertilization, mammalian spermatozoa must undergo capacitation and the
acrosome reaction (AR) within the female reproductive tract. However, the effects of …

In the study, melatonin, a known antioxidant pineal peptide was used as an additive in the
tris-egg yolk glycerol-based semen extender in Hariana bull semen and post-thaw sperm …

The progesterone (P4) secreted by cumulus cells has gained attention for its role as a
possible physiological inducer of sperm acrosome exocytosis. In mammals, it is generally …

Calcium ion enters the sperm through a specific calcium channel, CatSper. This voltage‐
sensitive channel is stimulated by intracellular alkalization and progesterone. This study is …
