Explanation
Each ovary is enclosed in a tough protective capsule and contains many follicles. A follicle consists of one egg cell surrounded by one or more layers of follicle cells, which nourish and protect the developing egg cell. Each female ovary potentially contains 200,000 follicles. Formed before her birth, of these, only several hundred will release egg cells during the female reproductive years.
