What causes a man to not produce sperm?
The three major causes for lack of sperm production (Non-Obstructive Azoospermia, or NOA) are hormonal problems, testicular failure, and varicocele. The testicles need pituitary hormones to be stimulated to make sperm, specifically FSH and LH.
What are the symptoms of lack of sperm?
Low sperm count symptoms might include:
- Problems with sexual function — for example, low sex drive or difficulty maintaining an erection (erectile dysfunction)
- Pain, swelling or a lump in the testicle area.
- Decreased facial or body hair or other signs of a chromosome or hormone abnormality.
