UCLA graduate student Jeffrey Riffell and UCLA biology professor Richard Zimmer report the first experimental test on the role of small-scale physics as it influences the interactions between sperm ...

Insect glands are responsible for producing a host of secretions that allow bees to sting and ants to lay down trails. New research focuses on secretions from glands in the reproductive tract that ...

Researchers at ETH Zurich recently developed highly realistic simulations of the proteins on sperm and egg cells coupling together before they fuse. These findings enabled the research team to solve ...

Knowledge of the sperm-specific protein that is required for the attachment of sperm to eggs during fertilization in mammals has led to the identification of the protein's receptor on the egg's plasma ...

Infertility is a challenge that many couples face and it can affect both men and women. There are various reasons for ...

The development of every animal in the history of the world began with a simple step: the fusion of a spermatozoon (the male gamete) with an oocyte, or egg (the female gamete). Despite the ubiquity of ...

Scientists are developing a new way to help infertile women have babies. A mature cell from the woman's body is merged with a chromosome-free egg, to which sperm is later added. The scientists insist ...
