n

Follicles are small sacs that cover immature eggs. Following the release of FSH hormone, the ovaries in About 5 to 20 follicles They are building. Finally, the healthiest egg has reached maturity and the rest of the follicles are absorbed by the body. The follicle provides a nutrient-rich environment for the development of the embryo in case of fertilization. Also, at this stage, with the increase of estrogen hormone, The endoderm layer of the uterus grows and thickens.
