Ovary - Corpus Luteum

The corpus luteum is formed by both granulosa cells and thecal cells after ovulation has occurred. The wall of the follicle collapses into a folded structure, which is characteristic for the corpus luteum. Vascularization increases and a connective tissue network is formed. Theca interna cells and granulosa cells triple in size and start accumulating lutein (Which hormone stimulates this process? Where is this hormone produced?) within a few hours after ovulation. They are now called granulosa lutein cells and theca lutein cells and produce progesterone and oestrogens.

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.
