Sperm quality linked to living longer, new study finds

By Sandee LaMotte, CNN (CNN) — People who have higher levels of strong, agile sperm may live nearly three years longer than those with poor swimmers incapable of making it to their destination, according to new research. The large-scale study followed more than 78,000 men for 50 years. The ability of sperm to properly swim through the female reproductive tract to reach and fertilize an egg is called motility. “In absolute terms, men with a total…

Revealing the Essential Protein Complex for Male Fertility

In an astonishing revelation from a research team at Osaka University, the intricate world of sperm development has been further illuminated. The study, soon to be published in the prestigious journal Proceedings of the National Academy of Sciences (PNAS), uncovers a critical protein interaction that plays a pivotal role in sperm formation. This research presents an exciting insight into the mechanisms of spermiogenesis, a complex biological pro…

A colorized scanning electron micrograph reveals in fine detail human sperm traveling through a fallopian tube. Ciliated cells (purple with hairlike extensions) help move eggs from the ovary to the uterus and regulate flow of fluid. Secretory cells (green) produce a nutrient-rich fluid that bathes sperm and egg. Image courtesy of Steve Gschmeissner. The post Science in Pictures appeared first on Sanford Burnham Prebys.
