Male infertility is undercovered and underdiscussed. If a couple is struggling to conceive, there’s a 50–50 chance that sperm health is a contributing factor. Diagnosing male infertility is getting easier with at-home tests—and a new study suggests a method for testing at home that would be more accurate. Study co-author Sushanta Mitra, a professor of mechanical and mechatronics engineering at the University of Waterloo in Ontario, joins host Rachel Feltman to discuss how lower sperm adhesion could be used as a proxy for higher sperm motility.
