Which of the following is a cause of male infertility?

Correct option is C

Hormonal disorders, including those affecting the pituitary gland, hypothalamus, and testicles, are a significant cause of male infertility. These disorders can lead to abnormalities in the hormones that regulate sperm production and function. For example, insufficient testosterone or luteinizing hormone (LH) levels may impair sperm production.
Explanation of each option:
· (a) Problems with ovulation, such as irregular or absent ovulation – Incorrect. This is a cause of female infertility, not male infertility. Ovulation problems prevent the release of eggs for fertilization.
· (b) Endometriosis – Incorrect. Endometriosis is a female reproductive condition where tissue similar to the uterine lining grows outside the uterus, often causing infertility in women.
· (c) Hormonal disorders leading to abnormalities in hormones produced by the pituitary gland, hypothalamus, and testicles – Correct. These hormonal disorders affect sperm production and function, making it a common cause of male infertility.
· (d) Follicular disorders – Incorrect. Follicular disorders affect the female reproductive system, specifically the ovaries, and thus relate to female fertility issues, not male fertility.
