Question

Quizplus · Accepted Answer

Menarche is the first menstrual period experienced by girls, which indicates the ability to conceive a child. Spermarche, on the other hand, is the first occurrence of ejaculation in boys, indicating the ability to fertilize an egg. Thus, the correct option is D - menarche; spermarche. Option A is incorrect because spermarche refers to the first ejaculation, not the first menstrual period in girls. Option B is incorrect as menstruation refers to the monthly shedding of the uterine lining in girls and women, not the first sign of being able to have a child. Option C is incorrect as arousal is not a biological sign of reproductive ability for either gender.
