Before the process of fertilization, spermatozoa necessitate a period of residence in the
female reproductive environment, and undergo a sequence of physiological and …

Mammalian fertilization relies on sperm finding the egg and penetrating the egg vestments.
All steps in a sperm's lifetime crucially rely on changes in the second messenger cAMP …

The fibrous sheath (FS) is a flagellar cytoskeletal structure unique to sperm that surrounds
the outer dense fibers and axoneme. Its primary components are A-kinase anchoring …

ABSTRACT Ca2+-binding tyrosine-phosphorylation-regulated protein (CABYR) has been
implicated in sperm physiological function in several in vitro studies. It has also been …

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

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

Simple Summary This study tackles the genetic aspects of the risk of sperm damage and
related impaired fertility when handling frozen–thawed bull semen for artificial insemination …

BACKGROUND Plant viruses can facilitate their transmission by modulating the sex ratios of
their insect vectors. Previously, we found that exposure to tomato spotted wilt …

Spermatozoa need to conduct a series of biochemical changes termed capacitation in order
to fertilize. In vivo, capacitation is sequentially achieved during sperm transport and …

Fibrous sheath CABYR binding protein (FSCB) is regulated by protein kinase A (PKA)-
mediated tyrosine phosphorylation in the spermatozoa capacitation. Recently, we showed …
