Corpus luteum

Corpus luteum

(Science: gynaecology) a yellow glandular mass in the ovary formed by an ovarian follicle that has matured and discharged its ovum. The corpus luteum secretes progesterone.

If the ovum has been impregnated, the corpus luteum increases in size and persists for several months (corpus luteum graviditatis).

If impregnation has not taken place, the corpus luteum degenerates and shrinks (corpus luteum menstruationis).

Synonym: yellow body of ovary.

Re: What kills (and what saves) a corpus luteum?

You've asked a question that isn't completely answerable yet - here's a bit of info: http://physrev.physiology.org/cgi/content/full/80/1/1 I would guess that a shutdown of the blood supply is somehow involved as well.
