But then, neither have most scientists, even though Drosophila is one of the most thoroughly studied lab animals. Now a team of biologists at the University of California, Davis, has taken the first deep look at the Drosophila uterus and found some surprises, which could have implications not just for understanding insect reproduction and potentially, pest control, but also for understanding fertility in humans.&nbsp;</p> October 25, 2024 - 11:06am Andy Fell /news/invisible-anatomy-fruit-fly-uterus Protein Integral to Sperm Development and Male Fertility Identified /blog/protein-integral-sperm-development-and-male-fertility-identified <p><span><span><span><span><span><span>Early in the development of sperm, a strange event happens: the X and Y chromosomes condense into tight packages and are sequestered away from the other 44 human chromosomes. If any part of this process goes awry, the cells cannot mature into sperm. Researchers in the ºÙºÙÊÓƵ College of Biological Sciences have now identified an important link in this process — a little-known protein called ATF7IP2.</span></span></span></span></span></span></p> February 21, 2024 - 3:20pm Andy Fell /blog/protein-integral-sperm-development-and-male-fertility-identified Immune Cells Drive Sex Reversal in Zebrafish – and Perhaps Fertility Loss in Women /blog/immune-cells-drive-sex-reversal-zebrafish-and-perhaps-fertility-loss-women <p><span><span><span><span><span><span>Female zebrafish (<em>Danio rerio</em>) have an unusual tendency: if their egg cells are damaged, they can turn into males.

From birth, females possess a limited number of primordial follicles, collectively called the ovarian reserve. Within each follicle is an oocyte that eventually becomes an egg. But with age, the follicles in the ovarian reserve decrease. </span></span></span></span></span></span></span></span></span></span></span></p> August 10, 2022 - 8:20am Andy Fell /health/news/study-reveals-how-ovarian-reserve-established
