Corpus Luteum
Updated:The corpus luteum is a temporary endocrine structure that forms in the ovary after ovulation. It develops from the remnants of the ovarian follicle that released an egg during ovulation. This small, yellow body plays a crucial role in the menstrual cycle and early pregnancy by producing hormones, primarily progesterone and some estrogen.
Additional Information
The corpus luteum typically lasts for about 14 days if pregnancy doesn't occur. During this time, it produces hormones that prepare the uterus for a potential pregnancy by thickening the uterine lining. If pregnancy occurs, the corpus luteum continues to produce hormones for the first trimester, supporting the developing embryo until the placenta takes over hormone production.
If pregnancy doesn't occur, the corpus luteum degenerates, leading to a drop in hormone levels that triggers menstruation. This structure is essential for maintaining the regularity of menstrual cycles and supporting early pregnancy.
Examples
During fertility treatments, doctors may monitor the development of the corpus luteum to ensure proper hormone production.
In some cases, a corpus luteum may develop into a cyst, which can cause pelvic pain and require medical attention.
