Two new papers from reproductive biologists at the University of Massachusetts Amherst, with international partners, report advances in understanding the basic processes of sperm capacitation that may one day improve success rates of in vitro fertilization (IVF) by providing a shortcut to bypass problems, and may eventually lead to a male contraceptive.
A "pill for men" may be a long way down the road, says Pablo Visconti, lead UMass Amherst author, but this new fundamental knowledge of how sperm acquire the ability to fertilize an egg, letting scientists either block or enhance the process, is at the heart of being able to control it. Findings by the international research teams appear in early online editions this month of Proceedings of the National Academy of Sciences (PNAS) and the Journal of Biological Chemistry (JBC), which named one study a finalist for "Paper of the Week."
