How big does the follicle have to be before ovulation occurs?

The follicle is one of the important elements of reproduction. Without the follicle, women cannot become pregnant and give birth. Of course, it will only ovulate when it develops to a certain size. Therefore, how big the follicle must be before ovulation occurs is a question that women are very concerned about, so that they can take some preparatory measures in time. Let us briefly understand how big the follicle must be before ovulation occurs?

Follicles larger than 18mm are considered dominant follicles and can be fertilized if released. When a normal follicle grows to 18×19mm and the endometrium is 8mm thick, it is time for ovulation. But it should be noted that the size of the follicle when it is discharged varies from person to person. If you find that the follicle is larger than 1.8, you can test it every day. The daily growth rate of the follicle is 1-3mm. Pregnant mothers can go to the hospital for testing depending on the situation.

It is considered normal when the diameter of the follicle reaches 18-25mm. The size of the follicle when ovulation occurs depends on the individual. Some ovulate when the follicle grows to 15mm, while others need it to grow to 25mm. Follicular development is a continuous process, and the normal follicle diameter should be between 18-25mm.

The growth from primary follicle to mature follicle can be divided into 8 levels. It takes a total of 10 days from the 6th level follicle to the 8th level follicle, which is exactly the follicular phase in a menstrual cycle. Starting from 16mm, after another 2-3 days, it will develop into a 20mm follicle and then be discharged.

The pregnancy rate is relatively high when the follicles are between 18-25mm. Conception can only occur when the follicles are mature and ruptured. You can go to the hospital for an ultrasound in 3 days to see if the follicle has ruptured. If it has, that is the best time to have sex.

When is the egg released: The day of ovulation is the next menstrual period minus 14 days.

Generally speaking, a woman's ovulation day is about 14 days before the next menstrual period. To be on the safe side, we call the 5 days before ovulation, 4 days after ovulation, and the 10 days including the ovulation day the ovulation period. If your menstrual cycle is irregular, you can check whether you have ovulated by measuring your body temperature, cervical mucus, etc.

Generally speaking, a woman only ovulates once a month.

After entering puberty, due to the secretion of gonadotropin by the pituitary gland, the primordial follicles in the ovaries begin to develop and synthesize estrogen. The space around the egg cells is filled with fluid containing a large amount of estrogen. The growing follicle gradually moves to the surface of the ovary, the follicle wall becomes thinner and thinner, and finally ruptures. The mature egg flows into the abdominal cavity along with the follicular fluid. This process is called ovulation.

Women of childbearing age generally ovulate one ovulation per month, which can be released alternately from the left and right ovaries, or continuously from one ovary. Ovulation is related to factors such as environment, mood, physical health, sexual life, and contraceptive drugs. Sometimes ovulation may occur early or two eggs may be released at a time, and sometimes ovulation may be delayed or temporarily not occur.

Generally, when a woman's follicles grow to a certain size and ovulate, there are many symptoms. Most women will experience an increase in leucorrhea, and vaginal secretions will gradually increase. The secretions are thin and milky white, and there will be a faint slippery feeling in the genitals. This is also one of the important manifestations of female ovulation.
