Sperm cells mature in the epididymis, a 20-foot-long series of thin, tightly coiled tubes. Sperm take from two to 12 days to pass through the epididymis and to develop the ability to swim and ...

Generational wounds may live in our genes. New research suggests that childhood trauma leads to a difference in the epigenetics of a sperm cell, which can impact a child's development and also be ...

Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are ...

Henking noticed that some wasp sperm cells had 12 chromosomes, while others had only 11 chromosomes. Also, during his observation of the stages of meiosis leading up to the formation of these ...

Fathers may carry traces of their childhood trauma in their sperm cells, a new study finds. The new research, published Jan. 3 in the journal Molecular Psychiatry, looked at the "epigenetics" of ...

He has a background in neuroscience and earned his ... “At this point, we should expect the unexpected from sperm,” Webster says. “Sperm are so radically different from any other cell type. They ...

Meiosis, as described above, is the process by which certain sex cells are created. If you're male, your body uses meiosis to create sperm cells; if you're female, it uses meiosis to create egg cells.
