Millions of couples who have trouble conceiving may get relief from new research led by scientists at The University of Texas at San Antonio. The researchers have developed a high-resolution genetic map showing how men produce sperm cells. Their effort could help address genetically based challenges with male fertility, a major cause of conception problems.

The researchers’ findings reveal detailed information about which genes are turned on or off in stem cells that ultimately grow into sperm cells. This data could give doctors crucial insight into the development of sperm in a patient, a perspective that was lacking up until now.
