Final answer:
Primary follicles that do not mature do undergo atresia during folliculogenesis.
Step-by-step explanation:
The statement that primary follicles that do not mature undergo atresia is true.
In the process of folliculogenesis, ovarian follicles progress from primordial, to primary, to secondary, and finally to tertiary follicles. Most follicles undergo atresia and do not reach the fully mature stage before ovulation. In fact, approximately 99 percent of follicles in the ovary undergo atresia at some stage of development.
