Revealing the TMEM217-SLC9C1-sAC Axis: A Key Switch in Sperm Motility and Male Fertility
Understanding the Challenge: Male Infertility and Sperm Motility Infertility affects about one in six couples, and nearly half of these cases involve male factors. A common culprit is sperm that fail to swim effectively, a problem tied to the delicate signaling that powers tail movement. In a groundbreaking study from the University of Osaka, scientists…

Centromere Balance Explains Why Some Embryos Stall During Development
Centromeres as Gatekeepers in Early Development When a sperm fertilizes an egg, the resulting zygote must reorganize parental DNA into a unified genome before the first cell division. A key, but often overlooked, player in this process is the centromere, the chromosome region that helps pull sister chromatids apart during division. For years, scientists assumed…

The Science Behind Gender Selection in Pregnancies
For years, many believed that conceiving a boy or a girl was merely a matter of chance, like a coin toss with equal odds. However, a groundbreaking study published on July 18, 2025, in Science Advances challenges this notion. Researchers analyzed extensive data and found that biological and environmental factors significantly influence a couple’s likelihood…
