Corpus luteum (gross pathology)

Case contributed by Ed Uthman

Patient Data

Gender: Female

This normal ovary was removed in the course of a hysterectomy for uterine disease. The bright yellow corpus luteum is fully developed, as it would be in the mid-luteal phase of the menstrual cycle following ovulation. The corpus luteum produces progesterone, which supports the endometrium's ability to accommodate the implanted conceptus. If a conceptus implants, the corpus luteum grows even bigger, to form the so-called "corpus luteum of pregnancy." If no pregnancy occurs, the corpus luteum shrinks dramatically to become a corpus albicans. This ovary also sports several corpora albicantia from previous months' cycles, one of which is marked.
