Factors of azoospermia Why do your testicles lack the production of sperm? Some of the factors of azoospermia are given below: Pretesticular azoospermia: In this condition, your testicles are fine but body fails to make sperm. It may occur due to low hormone levels. Testicular azoospermia: It happens because of some damage done to the testicles which prevents them from producing sperms naturally. It could be because of genetics, cancer or its treatment, childhood problem or infection of the reproductive tract. Post-testicular azoospermia: In this condition, your testicles produce normal sperm, but something stops it from getting out like blocked tubes which carry sperm to penis, vasectomy or retrograde ejaculation.
