Millions of couples worldwide experience infertility with half of the cases originating in men. For 10% of infertile males, little or no sperm are produced. Now, new research from the Stowers ...

The human body is full of checks and balances that ensure correct growth, development, and function of all our different systems. Now, researchers from Japan have reported a newly discovered protein ...

Investigators have employed mutant mice to study how the accumulation of genetic errors is managed during egg and sperm formation. Sometimes the best way to understand a biological process is to ...

Researchers are delving into the molecular-level details of sperm formation, with a particular focus on how abnormalities in this process might lead to male-factor infertility. Sperm play a critical ...

Sperm are often described as relentless swimmers, racing toward the egg with little strategy beyond movement. But fertilisation is not a sprint. It is a sequence of controlled activations, delays, and ...

Paterna Biosciences says it has determined the set of instructions needed to turn sperm-making stem cells into "normal, ...

A new study suggests that researchers may be moving closer to developing a new form of contraception for men.

Electron microscope image of mouse sperm head. The mouse sperm head is characterized by a crescent shape, whereas in TEX38-deficient sperm the head is bent backward 180 degrees. Osaka, Japan – The ...

Sperm play a critical role in the creation of new life, delivering essentially half of the genetic material required. The success of this process relies on the generation of a developmentally ...
