Do a Man’s Testicles Shrink After Prostate Surgery and Radiation?

It’s a question many men hesitate to ask, but it’s an important one: can prostate cancer treatment affect the size of the testicles? The answer, in some cases, is yes—not directly because of surgery itself, but potentially due to radiation or other cancer treatments.

Prostate surgery typically focuses on removing or treating the prostate gland, which means the testicles aren’t the direct target. However, treatments like radiation therapy, especially if directed near the pelvic region, can sometimes impact nearby tissues. While modern techniques aim to minimize collateral damage, the testicles may still be exposed to some degree of radiation, potentially leading to a condition called testicular atrophy—where the testicles shrink in size and may lose some function.

This doesn’t happen in every case, but it is a recognized possibility. Radiation can affect blood flow and hormone production in the testes, which in turn can lead to volume loss over time. Hormone therapies, often used alongside radiation or surgery for prostate cancer, can also contribute by lowering testosterone levels, which may result in reduced testicular size.

It’s also worth noting that aging naturally causes some shrinkage, so distinguishing treatment effects from normal changes isn’t always straightforward. Still, if a man notices significant changes after treatment, it’s worth discussing with a urologist. Solutions may include hormone replacement or other supportive therapies.

Bottom line: While not guaranteed, testicular shrinkage can occur after radiation or hormonal treatment for prostate cancer. Awareness and open conversations with healthcare providers help men manage both physical and emotional aspects of recovery.
