What Testosterone Does to Your Fertility, and What to Know

September 2, 2026

For as long as we've talked about fertility, it's been treated as a woman's problem. Her labs. Her hormones. Her clock. Meanwhile half the equation is standing quietly in the background, and nobody is asking about him. Dr. Georgine Nanos sits down with Dr. Kian Asanad, a fellowship-trained reproductive urologist and microsurgeon who directs the USC Fertility and Men's Sexual Health Center and teaches urology at Keck Medicine of USC. He has published more than 40 peer-reviewed papers, including in JAMA, and he spends his days doing the part of fertility medicine most people never hear about. If you or your partner have been told her labs are fine and you're still not pregnant, the missing piece may not be in her chart at all.
