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.

An essential component of every 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 ...

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

New research finds that the atypical centriole in the sperm neck acts as a transmission system that controls twitching in the head of the sperm, mechanically synchronizing the sperm tail movement to ...

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 ...

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 ...

Male infertility is a major issue worldwide and its causes remain unclear. Now, an international team of researchers led by Hiroki Shibuya at the RIKEN Center for Biosystems Dynamics Research (BDR) in ...
