Does low testosterone cause infertility?

No, low testosterone cannot cause male infertility, but it may interfere with general fertility by reducing sex drive or causing erectile dysfunction. Sperm production can be affected by low testosterone, but it is very rare as the process of sperm production is primarily stimulated by other hormones than testosterone. Men with low testosterone levels are often able to conceive naturally, as the concentration of testosterone is significantly higher in the testicles, where the sperm is produced, than in the blood.
