Detailed explanation-1: -Ovarian follicles are small sacs in the ovaries that hold immature eggs. Each month, between days six and 14 of your menstrual cycle, follicle-stimulating hormone (FSH) causes follicles in one of your ovaries to mature.

Detailed explanation-2: -Right before ovulation, the egg inside the follicle detaches itself. The follicle starts to release chemicals that encourage the nearby fallopian tube to move closer and surround the follicle. The follicle swells until it bursts open, ejecting the egg and fluid into the abdominal cavity.

Detailed explanation-3: -The eggs are stored within follicles in the ovary. Within a woman’s lifespan, large numbers of follicles and oocytes will be recruited to begin the growth and maturation process.

Detailed explanation-4: -For both fertile and infertile women ovulation from the right ovary occurred more often than from the left ovary (55 versus 45%; P: < 0.005). In infertile women follicular phase length was similar for right-and left-sided ovulation.

Detailed explanation-5: -But the fact is that there are tons of other eggs that don’t make it past that first stage. Each cycle, maybe 15–20 follicles are activated, but when they don’t mature, they get “reabsorbed” (AKA, they die). This process is called “atresia.”
