/ˈluːtɪəm
/noun (plural corpora lutea /ˈluːtɪə/) Anatomy
A hormone-secreting structure that develops in an ovary after an ovum has been discharged but degenerates after a few days unless pregnancy has begun.It is generally believed that symptoms result from the waning hormone secretions from the ovaries as the corpus luteum begins to degenerate towards the end of the menstrual cycle....
- It is secreted by the corpus luteum during pregnancy and by the ovaries during the luteal phase of the menstrual cycle.
- In the corpora lutea of the ovary, whirls of long needles are most distinct.
