Follicles are tiny sacs inside a woman's ovaries that are filled with fluid.
Follicles, their size, and their status are crucial in determining fertility and treatment options.
Each follicle is capable of producing an egg for fertilization.
They produce hormones that affect the menstrual cycle's stages.
Women have between 300,000 and 400,000 follicles when they start puberty.
FSH stimulates the maturation of follicles.
GnRH induces the pituitary gland to release follicle-stimulating hormone (FSH), which initiates follicle (egg) growth and raises estrogen levels (the key female hormone).
The other reproductive pituitary hormone, luteinizing hormone (LH), assists in egg maturation and provides the hormonal trigger for ovulation and the release of eggs from the ovary.
