Which of the following is NOT a common male-factor infertility cause?

Explanation:
In infertility, most male-factor problems involve how sperm are produced or function. Oligozoospermia means a low sperm count, and azoospermia means no sperm in the ejaculate—both reflect direct issues with male spermatogenesis or sperm presence. Varicocele can impair spermatogenesis by increasing scrotal temperature and causing oxidative stress, another clear male-factor issue. Endometriosis is a female gynecologic condition in which tissue similar to the lining of the uterus grows outside it; it can cause infertility in women but has no effect on male reproductive physiology. So it does not represent a common male-factor infertility cause.
