Follicles are formations in the ovaries that represent the rudiments of eggs. Although the number of follicles in the ovaries is not limited, usually 500-100 thousand of them are in a state of readiness to produce an egg. This process is called the sexual cycle. The number of follicles potentially ready for ovulation is called follicular reserve. It is believed that in women under 30 years of age it is 400 follicles. However, with age, the reserve decreases. In women during menopause, the follicular reserve becomes smaller. The most important follicle is considered to be a follicle whose size is approximately one centimeter, since it is the one that carries the egg. The greater the number of follicles of this size, the higher the likelihood of successful conception. Others
