Granulosa cell

Granulosa cells are a type of cell that are part of the ovary in the female reproductive system. They are involved in the production of sex hormones and the development of ova.

Function

Granulosa cells have several important functions in the female reproductive system. They are involved in the production of sex hormones, including estrogen and progesterone, which are essential for menstrual cycles, pregnancy, and menopause. They also play a crucial role in the development of ova, or eggs, which are necessary for fertilization and reproduction.

Structure

Granulosa cells are found in the ovarian follicle, which is a small sac in the ovary that contains an immature egg. They surround the egg and provide it with nutrients and hormones necessary for its development. As the follicle matures, the number of granulosa cells increases, and they begin to produce estrogen.

Clinical significance

Abnormalities in granulosa cells can lead to a variety of medical conditions. For example, granulosa cell tumors are a type of ovarian cancer that originates from granulosa cells. These tumors can produce large amounts of estrogen, leading to symptoms such as abnormal menstruation and endometrial hyperplasia.

Polycystic ovary syndrome (PCOS) is another condition that can be associated with abnormalities in granulosa cells. In women with PCOS, the granulosa cells may not function properly, leading to an imbalance in sex hormones and the development of multiple small cysts in the ovaries.
