Males of the species Drosophila melanogaster pack thousands of almost two-millimeter-long sperm cells into significantly smaller storage organs. A new study reveals how they move in an orderly manner ...

Fruit flies’ giant cells rely on collective motion, pushing against each other to prevent their flagella from tangling ...

Tails take up most of the real estate on a sperm cell. They may have tiny bodies, but fruit flies produce giant sperm. Adult ...

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 ...

When Jasmin Imran Alsous peered down her microscope lens, she expected to see chaos—a mishmash of tangled cells. She was ...

The sperm tail moves very rapidly in 3D, not from side-to-side in 2D, as it was believed. Source: Image credited to polymaths-lab[dot]com New state-of-the-art 3D microscope technology combined with ...

How a sperm and an egg fuse together has long been a mystery. New research by scientists in Austria provides tantalizing clues, showing fertilization works like a lock and key across the animal ...

Beads left magnetic sperm healthier than untagged cells, and a magnet steered them to an egg, a step toward conception inside ...

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.
