A fluid structure formed from the Graafian follicle after ovulation is called what?

• A. Corpus luteum
• B. Corpus albicans
• C. Graafian follicle
• D. Ovarian stroma

Answer: (A)

After ovulation, the ruptured Graafian follicle undergoes luteinization and becomes the corpus luteum, a temporary endocrine gland formed from the remaining follicular cells. Its primary role is to secrete progesterone (along with some estrogen) to prepare and maintain the endometrium for possible implantation. If fertilization occurs, human chorionic gonadotropin from the developing embryo keeps the corpus luteum active until the placenta takes over hormone production. If no pregnancy occurs, the corpus luteum degenerates into a fibrous scar called the corpus albicans. The other ovarian structures are distinct: a Graafian follicle is the mature follicle before ovulation, and the ovarian stroma is the connective tissue framework of the ovary.
