What is the difference between a Graafian follicle and a corpus luteum?

Graafian Follicle and Corpus Luteum:

1. The Graafian follicle is a fully grown follicle that ruptures during the ovulatory phase and releases the ovum.
   
2. After ovulation, the Graafian follicle develops into the corpus luteum. During the first trimester of pregnancy, a mass of cells called a corpus luteum forms in the ovary and is in charge of producing progesterone.
   

Graafian Follicle	Corpus Luteum
The Graafian follicle converts into the corpus luteum after ovulation, which secretes progesterone and is necessary for pregnancy maintenance.	This is a collection of cells that originates inside our ovaries during each menstrual cycle.
2. Female reproductive biology is built around ovarian follicles. There is only one oocyte in each of them (immature ovum or egg cell).	2. It occurs shortly after an egg has been released from your ovary.
3. These structures grow and develop on a regular basis, culminating in the ovulation of a single competent oocyte in humans. Granulosa cells and follicular theca are also found in them.	3. It secretes progesterone, a hormone that prepares your uterus for pregnancy. Our corpus luteum will disappear after it is no longer required to produce progesterone.
