CaMKII and CaMKIV are calcium/calmodulin-dependent kinases playing a rudimentary role
in many regulatory processes in the organism. These kinases attract increasing interest due …

The calcium/calmodulin-dependent protein kinase IV (CAMKIV) belongs to the
serine/threonine protein kinase family, and is primarily involved in transcriptional regulation …

Sperm motility is a natural selection with a crucial role in both natural and assisted
reproduction. Common methods for increasing sperm motility are by using chemicals that …

Mammalian sperm must undergo capacitation as a preparation for entering into
hyperactivated motility, undergoing the acrosome reaction, and acquiring fertilizing ability …

Background Capacitation, a prerequisite for oocyte fertilization, is a complex process
involving series of structural and functional changes in sperms such as membrane …

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 …

Background It is estimated that approximately 8–12% of couples globally face problems
associated with infertility. A large number of men exhibit suboptimal sperm parameters …

Considering the importance of calcium (Ca 2+) in regulating sperm capacitation,
hyperactivation and acrosome reaction, little is known about the molecular mechanism of …

Successful male fertilization requires the main processes such as normal spermatogenesis,
sperm capacitation, hyperactivation, and acrosome reaction. The progress of these …

Boar semen cannot be immediately cryopreserved, it need be hold at 17° C prior to
cryopreservation, holding time has been used to improve cryopreserved boar semen, since …
