Given below are two statements: Statement I: The normal reproductive phase in a human female extends between menarche and menopause. Statement II: At puberty, each ovary contains only about 60,000 to 80,000 primary follicles. In the light of the above statements, choose the correct answer from the options given below.

Step-by-step solution

Statement I is correct as cyclic menstruation is an indicator of the normal reproductive phase, which begins at menarche (the first menstruation at puberty) and ends at menopause (cessation of cycles around 50 years of age). Statement II is correct as a large number of ovarian follicles degenerate during the phase from birth to puberty. Therefore, at puberty, only about 60,000 to 80,000 primary follicles are left in each ovary. Thus, both statements are correct. Answer: Both Statement I and Statement II are correct
