Feb. 15, 2024 When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered ...
Aug. 20, 2021 Researchers detail how a ubiquitous signaling molecule plays a critical role in male fertility, orchestrating key steps that promote sperm motility, survival and fertilization ...
July 19, 2022 The Prussian carp is considered one of the most successful invasive fish species in Europe. Its ability to reproduce asexually gives it a major advantage over competing fish. An international ...
May 17, 2021 Sperm are generally viewed as having just one action in reproduction -- to fertilize the female's egg - but studies are overturning that ...
Oct. 19, 2021 A new study shows that functional sperm cells can be made in a dish using primate embryonic stem ...
Dec. 2, 2021 An intense but short-term exposure to cannabis vapor lowered sperm counts and slowed sperm movement, or motility, not only in the directly exposed male mice but also in their sons, according to a new ...
Sep. 7, 2021 For species that rely on sexual reproduction, including mice and men, offspring can only happen if sperm from the male fertilize eggs from the female. Even artificial fertilization techniques depend ...
Nov. 15, 2022 The behavior of sperm cells is due, in part, to the individual DNA make-up of these cells, rather than only to the genetics of males. The results, which provide a new understanding of the competition ...
Jan. 18, 2024 A new study finds that a small group of microorganisms may be influencing sperm ...
Oct. 26, 2023 Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of ...
