Quizplus · Accepted Answer

As men age, there is a natural decrease in the quantity and quality of their sperm. This can lead to longer times to impregnate a partner, with men over the age of 40 taking approximately three times longer than men under age 25, as the question states. Options A (lack of libido) and B (endometriosis) are not directly related to male fertility. Option D (their partner's fertility) is a possibility, but not the primary reason for the age-related decrease in male fertility.
