The term sperm refers to the male reproductive cells. In the types of sexual reproduction known as anisogamy and oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.

Hints to aging lurk in fruit flies’ germline stem cells

Little hints of immortality are lurking in the stem cells of fruit flies. Stem cells that produce sperm use a genetic trick to stay perpetually young across generations, researchers at the University of Michigan Life Sciences Institute have discovered. Certain sections of the fruit fly genome get shorter with age. But remarkably, some reproductive cells can repair the shrinkage, the researchers report in the journal eLife.

Study provides insights into how obesity may contribute to male infertility

A new study sheds light on how obesity may contribute to male infertility. Published in open-access journal Frontiers in Physiology, the study reports that obese men have increased levels of inflammatory markers in their seminal fluid and lower sperm quality, both of which correlate with their body mass index.

New insights into mosquito sex protein could provide strategies to control diseases

If you thought the sex lives of humans were complicated, consider the case of the female Aedes aegypti mosquito, bringer of Zika, dengue, and yellow fever: She mates but once, in seconds and on the wing, with one lucky male; spurns all further advances from other potential suitors; and stores enough sperm from that single encounter to lay more than 500 eggs, which she nourishes with the blood of human hosts.
