Can follicle 13 be released within three days?

The follicles exist in the female ovaries. Because of the secretion of female estrogen, they continue to grow until the follicles rupture and form eggs. So the size of the follicles is different in each different period. Before undergoing in vitro fertilization, doctors will test the size of the follicles in a woman's body so that they can estimate when the egg will be released. So if the follicle is 13 mm in size, can it be discharged within three days?

1. How big does a follicle have to be before it is discharged? When the diameter of the follicle reaches 18-25mm, it will be discharged naturally. Follicle development is a continuous process. The diameter of a normal follicle should be between 18-25mm. When a woman has her first menstruation, the number of follicles in her ovaries reaches 300,000-500,000. Every month, a batch of follicles develop, of which only one dominant follicle can fully mature and release an egg, while the rest degenerate on their own. Only 400-500 follicles develop, mature and are released during a woman's lifetime. 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.

Therefore, it is unlikely that follicle 1.3 will be discharged within three days. However, the size of the follicle when it is discharged depends on the individual. Some follicles are discharged when they grow to 15mm, while others need to grow to 25mm.

2. When is the follicle released? The egg is released about 14 days before the next menstrual period. The day the egg is released is the ovulation day. 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. Women with irregular menstrual cycles cannot use this method to predict when the egg will be released, but they can see whether ovulation has occurred by measuring basal body temperature, observing cervical mucus, etc. During the ovulation period, the body will experience some subtle changes, which may be accompanied by symptoms such as slightly higher body temperature, lower abdominal pain, and breast tenderness.

3. What does it feel like when the egg is released?

1. Lower abdominal pain: When the egg is discharged, it needs to break through a thin membrane follicle that wraps the surface. A small amount of fluid in the follicle will flow into the lowest part of the pelvic cavity, causing a small amount of bleeding. At this time, you will feel pain in one side of the lower abdomen, which will be relieved after a few hours.

2. Increased vaginal secretions: Vaginal secretions increase significantly and appear watery, transparent and clear. Women will feel their vagina is wet and slippery, and when they wipe it with toilet paper, there will be egg white-like strips of mucus.

3. Ovulation bleeding: After the follicle is discharged, the estrogen level drops sharply, causing local rupture and shedding of the endometrium, resulting in breakthrough bleeding. The amount of bleeding during ovulation is small and usually stops on its own within 2-3 days, and can last up to 7 days.

4. Slightly high body temperature: The body temperature is slightly higher when the egg is released, but the change is not obvious, generally fluctuating around 0.5 degrees Celsius.

5. Breast pain: During ovulation, the estrogen level in the body increases, breast hyperplasia, and edema of interbreast tissue lead to breast pain.

From the introduction in this article, we can know that the follicle will mature when it is 18mm-25mm, forming a mature egg, which will be discharged from the ovary and enter the fallopian tube. If you find that your egg has grown to 18mm-25mm in size, it means that the egg is about to be discharged from the ovary.
