Most men getting chemo can still have normal erections. But a few have problems. Erections and desire often drop right after getting chemo but return in a week or so.
Men who have had a bone marrow transplant are more likely to have a long-lasting loss of testosterone. In some cases, testosterone may need to be replaced to regain desire and erections.
Chemo rarely affects ejaculation. But there are some drugs that may damage the nerves that control emission. The semen may shoot back into the bladder instead of out through the penis.
Other problems from chemo that may affect your sex life
Chemo can cause genital herpes or genital warts to flare up if a man has had them before. If you have any signs of infection, see your doctor right away. Infections can be serious because chemo can weaken your immune system. This makes it harder for you to fight infections.
You’ll also want to avoid getting new infections from sex partners. If you are having sex with someone you’re not sure about, practice safer sex. The safest way to have sex is to use condoms every time, from start to finish. Whether you have oral sex (using the mouth), anal sex (entering the rectum), or vaginal sex, condoms can lower your risk of sexual infections.
For more about safer sex, contact the American Social Health Association (see the “To learn more” section).
