Calcium is an essential ion which regulates sperm motility, capacitation and the acrosome
reaction (AR), three processes necessary for successful fertilization. The AR enables the …

Sperm chemotaxis, which guide sperm toward oocyte, is tightly associated with sperm
capacitation, motility, and fertility. However, the molecular mechanism of sperm chemotaxis …

In mammals, sperm acquire fertilization ability after a series of physiological and
biochemical changes, collectively known as capacitation, that occur inside the female …

Despite the increasing use of protoplasts in plant biotechnology research, shoot
regeneration from protoplasts remains challenging. In this study, we investigated the factors …

Human sperm cell function must be precisely regulated to achieve natural fertilization.
Progesterone released by the cumulus cells surrounding the egg induces a Ca 2+ influx into …

Background Reports have shown that humans are consistently exposed to environmental
toxicants such as phthalate (PHT) during their daily activities. This results in reproductive …

In order to penetrate the egg, spermatozoa must undergo the acrosome reaction in close
proximity to the egg. This process can take place only after a series of biochemical changes …

Sperm gain fertilization competence in the female reproductive tract through a series of
biochemical changes and a requisite switch from linear progressive to hyperactive motility …

In order to fertilize the egg, spermatozoa must undergo a series of biochemical processes in
the female reproductive tract collectively called capacitation. Only capacitated sperm can …

The contribution of sperm to embryogenesis is gaining attention with up to 50% of infertility
cases being attributed to a paternal factor. The traditional methods used in assisted …
