How many mm can a woman's ovarian follicle grow in a day?

Women will produce a mature follicle every month, so the probability of women getting pregnant during ovulation will greatly increase. The growth of follicles is related to many factors. Most of the time, the follicles will grow larger every day until they are discharged normally during ovulation. When the follicle grows to a certain size, it means that the follicle is mature. So how many mm can the follicle grow in a day?

1. Under normal circumstances, the follicle can grow about 2 mm per day, but the specific amount of growth varies from person to person. If a woman is healthy, has sufficient qi and blood, normal immune function and normal endocrine system, then the follicles will develop faster and grow faster. When the follicle grows to more than 17 mm, ovulation can occur. If the body is weak, the qi and blood are insufficient, and the endocrine system is out of balance, the growth and development of the follicles will be slow, and ovulation may even disappear. Therefore, replenishing qi and blood and strengthening physical fitness are the key to promoting the growth and development of follicles.

2. The mature follicle will reach between 18 and 25 mm, and the mature follicle may be discharged within 24 to 48 hours. When the follicle matures, it may have three head pillows and its diameter may be greater than 18 mm. If the shape is round rather than oval, it means that the sound permeability is relatively good. Such follicles can be discharged quickly after maturity and have relatively strong ability to conceive. One follicle will grow in one menstrual cycle and develop to maturity, which is called the dominant follicle. Other follicles may be inhibited by inhibitory factors, stop growing and degenerate into atretic follicles. The diameter of the follicle on the 5th to 6th day of each cycle may be between 5 and 7 mm. By the 10th day, the diameter of the follicle may reach 10 mm, and the ultrasound display is relatively clear.

3. Under normal circumstances, the growth rate of follicles is an average of 1.5-2mm per day. After the menstruation is over, the size of the follicle is generally about 5mm. By the time of ovulation, the diameter of the follicle can reach 20mm. At this time, due to the increase in internal pressure, the follicle will rupture and expel the egg. Therefore, it is recommended that when monitoring follicles with B-ultrasound in clinical practice, it is necessary to understand whether the growth rate of the follicles is normal. If there is no ovulation or the follicle does not rupture clinically, it is recommended to check six sex hormones to understand whether the hormone levels in the body are normal. If the follicle reaches dominance, it is recommended to inject human chorionic gonadotropin into the muscle, which can promote the rupture of the follicle and the discharge of the egg.
