Ovary - Corpus Luteum

Histology image shows the corpus luteum (Latin, corpus = body; luteum = yellow)

  • The ovulating follicle forms initially the corpus hemorrhagicum and then corpus luteum.
  • Corpus luteum (CL, yellow body) outer layer consisting of theca lutein cells and more centrally the granulosa lutein cells.
  • Corpus luteum core is initially filled with a blood clot, following ovulation, and is the invaded by connective tissue.

Theca lutein cells and granulosa lutein cells work together in the production of ovarian hormones that support the initial pregnancy. Lack of implantation and associated hCG will lead to this structure not producing hormones and forming the corpus albicans (white body).

Hormone secretion in the corpus luteum ceases within 14 days after ovulation if the oocyte is not fertilised. In this case, the corpus luteum degenerates into a corpus albicans - whitish scar tissue within the ovaries.

Hormone secretion continues for 2-3 month after ovulation if fertilisation occurs.

The dark cell represent theca lutein cell the lighter ones are granulosa lutein cells.
