As the mesonephros degenerates (since it is a precursor to male tubular genitalia), the developing ovaries and ductular genitalia is enveloped in folds of peritoneum. This structure is called the genital fold and its divisions are named by the attached portions of the reproductive tract. The mesovarium supports and suspends the ovaries in the peritoneum. The mesosalpinx attaches to the uterine tube and portions of the ovary. The mesometrium (broad ligament of the uterus) supports the uterus in the pelvic canal and abdomen.
