Under normal circumstances, the number of follicles in both ovaries is not consistent, so 7 follicles on the left and 9 on the right are considered normal, and sometimes only one side ovulates and the other side does not ovulate. Of course, for women, follicles will only grow and be excreted periodically after the ovary function is mature, and the number of left and right follicles is normally less than 12. However, regardless of the number of follicles, only one follicle can mature each month, also known as the dominant follicle, and the rest of the follicles will become atresia.
The number of follicles in both ovaries is inconsistent
In general, it is normal for the number of follicles to be inconsistent in both ovaries. For women, only after the ovarian function is mature, the follicles will grow and be excreted periodically, and the number of left and right follicles is normally less than 12, so it is normal for the left follicle to have 7 follicles and 9 on the right. If a woman examines the number of follicles on the ovaries and finds that the number of follicles on the ovaries is greater than 12, and there are no dominant follicles, all of which are small follicles of 2-4mm, which are called polycystic changes of the ovaries, which are most common in women with polycystic ovary syndrome, that is, due to the dysfunction of ovarian endocrine function, the follicles on the ovaries cannot develop and mature, only small follicles grow and no large follicles are discharged.
The normal range for the number of unilateral ovarian follicles
There are several follicles in both ovaries of women developing at the same time, and 3-11 follicles on one side belong to the normal range, and too many or too few are abnormal, which may be related to premature ovarian failure or polycystic ovary syndrome, which may affect normal reproductive function. Of course, although the number of normal unilateral follicles is 3-11, only one follicle can mature every month, also known as the dominant follicle, usually at 15-2.Ovulation occurs at 8 cm, menstruation occurs about 14 days after ovulation, and the rest of the follicles become atresia.
Symptoms of follicular dysplasia
1. Menstrual cycle disorder: poor follicle development will cause irregular menstrual cycle, which is manifested as shortening or prolonging of menstrual cycle.
2. Amenorrhea: Poor early follicular development or premature ovarian failure can lead to amenorrhea, that is, no menstruation for a long time.
3. Infertility: poor follicle development leads to poor quality of eggs or inability to ovulate normally, and women are not easy to conceive or cause infertility.
