Question

Quizplus · Accepted Answer

Oligospermia is a condition in which the semen produced by a man when he ejaculates has a low concentration of sperm. This means that the man makes too few sperm, and as a result, the probability of one sperm successfully reaching and fertilizing an oocyte is lower. Thus, option C is the correct answer. Options A, B, and D are incorrect as they describe different conditions that are not related to oligospermia.
