At what size is the follicle considered mature and ready to be expelled from the body?

A woman's follicles come from the ovaries and are usually round in shape. The development of human follicles goes through three stages. The first is the primordial follicle. At this time, the follicles are very small in size, but there are more of them. Then they enter the growing follicle stage and finally the mature follicle stage. The mature follicles are the largest in size and will be discharged from the ovaries when they mature. So, generally speaking, how big a follicle is considered mature?

At what size is the follicle considered mature and ready to be expelled from the body?

Having a healthy baby is the wish of every family. Preparing for pregnancy is a key prerequisite for eugenics and good parenting. Before preparing for pregnancy, couples can conduct relevant pre-pregnancy examinations and make adjustments in all aspects of body and mind to give their baby a head start. Having a properly matured warm bubble is an important point in eugenics. So how big is a mature warm bubble?

First of all, we need to know the development process of warm bubbles. The follicle grows at a rate of 0.2CM per day. When the follicle develops to 1.8cm~2.5cm, it is considered mature. The mature follicle may be discharged at any time. The approximate ovulation time can be calculated based on this rate combined with the current follicle size. The characteristics of mature follicles, B-ultrasound monitoring shows that the largest follicle appears on the 10th to 16th day of menstruation. The follicle is 20mm in diameter, round in shape, with thin walls, protruding to one side of the ovary, and good internal sound transmission. Ovulation usually occurs within 10 hours. It is more common to ovulate within the 12th to 18th day of menstruation, and a few can occur at 20th to 30th day. Characteristics after ovulation: partial collapse of the follicle wall, the edges are wrinkled and jagged, with many faint light spots inside, and a 5~15mm liquid dark area can be seen in the uterine rectal crypts, which usually disappears one day after ovulation. The success rate of pregnancy is higher before and after this time.

Every month, women will only release one mature egg, and this mature egg is generally considered a mature egg if it is larger than 2.0mm. However, there are individual differences. Some people will release the egg when the follicle grows to 1.5mm, while others will release the egg when it grows to 2.5mm. The specific individual situation can be determined by a periodic B-ultrasound examination. Generally, mature follicles will be discharged within one to two days, and the discharged follicles can generally survive for 2 days.

Generally speaking, when the follicle develops to more than 1.8 cm, it may be discharged at any time. If it develops to more than 2.5 cm but cannot be discharged, it is abnormal. According to B-ultrasound, there are now two mature follicles. It is recommended to test ovulation again tomorrow and have sex from now on, because the follicle may be discharged at any time. Generally, the follicle survives for 1 to 2 days after being discharged, and the sperm survives for about 2 to 3 days after entering the body.
