Ovary - Corpus Luteum
Histology image shows the ovary in overview, the cortex and medulla of the ovary can be clearly seen.
Corpus luteum (yellow body) theca lutein cells and granulosa lutein cells. These cells work together in the production of ovarian hormones that support the initial pregnancy.
Corpus albicans (white body) lack of implantation and associated hCG will lead to this structure not producing hormones.
Atretic follicles are the degenerating follicles from various developmental stages that did not form the ovulating follicle and do not form the corpus luteum.
