Does male kidney disease affect sexual function?

Patient's question:

Hello doctor, recently my husband sweats a lot while eating and always has lower back pain. After each time we have sex, his lower back on both sides hurts. I'm very worried. He went to the hospital, but he didn't tell me what disease he has. Does male kidney disease affect sexual function? Thank you

Doctor's answer:

Having chronic kidney disease does not mean you have to say goodbye to sweet intimacy. It is advisable to moderate the frequency of sexual activity. The Chinese medical concept of "kidney" includes not only the organ but also the overall health of the body. Traditional Chinese medicine believes that the kidneys store essence and should not be excessively depleted. Frequent sexual activity can damage kidney essence and harm health. Therefore, patients with chronic nephritis should not be overly eager in their "five emotions" (anger, joy, worry, pensiveness, fear), should prioritize health preservation over desires, and find a proper balance between desires and health.
Recommendation: When chronic kidney disease is not fully controlled, especially during active phases (when symptoms like hematuria, proteinuria, or hypertension occur), sexual activity should be moderately restricted. For young people under 30, it is recommended to keep the frequency of sexual activity to about twice a week. Even after nephritis has been cured, complete relaxation of control is not advisable.
