When a couple struggles to conceive, the focus often falls on female fertility—but male factors contribute to nearly half of all infertility cases. Understanding male reproductive health is essential for couples hoping to build a family. In this episode of Dr. Jeff Talks About Sex & Intimacy, Dr. Jeff welcomes Dr. Robert E. Brannigan, a nationally recognized urologist and expert in male reproductive medicine from Northwestern Medicine, for an enlightening presentation and conversation about male fertility evaluation and optimization.
