Ultrastructure expansion microscopy of murine male germ cells reveals the fine molecular structures of centrioles (shown in the enlarged image). DNA is stained in blue, and the chromosome axis in red.

New insights into sperms' swimming skills shed light on male infertility, which affects one in 20 men, and could provide a new avenue to the development of a male contraceptive pill. In a study ...

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are ...

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 ...

There are many potential causes of infertility, and it can be challenging to pin down just what the problem is when a couple is having trouble getting pregnant. Now, researchers show that a few key ...

Millions of sperm enter the race to fertilize, but only one wins the sprint to the egg. Now Yale researchers have discovered that these winning sperm possess a few key molecular characteristics that ...

Accurate assessment of sperm function is pivotal for optimising outcomes in assisted reproductive technologies (ART). Traditional semen analysis—focusing on concentration, motility and ...

Researchers used protein sequence data analysis and genome editing technology to find that sperm protein SPATA33 plays an important role in sperm motility regulation. Their findings will aid in the ...

When considering how sperm move, the word "swimmers" comes to mind. The classic microscopic image is of a tiny cell swishing its tail from side to side as it propels forward. A new 3D model upends ...
