What is the chance of pregnancy with follicular puncture?

The chances of many women getting pregnant depend on sperm motility and female physical conditions. Therefore, many women cannot get pregnant for a long time, which affects the relationship and happiness between couples. Many women choose some methods of treating infertility to get pregnant, and many women choose follicle puncture for artificial pregnancy. So what are the chances? Let me introduce it to you below.

1. Time of follicle appearance:

At the beginning of each menstrual cycle, multiple follicles begin to develop at the same time, but generally only one or two follicles develop to maturity, called the primary follicles (dominant follicles), and the remaining follicles close one after another. Some authors have reported that in more than 90% of the cycles, only one follicle grows rapidly to maturity, and 5%-11% have two main follicles develop. The earliest time for ultrasound imaging of follicles can be 5-7 days of the menstrual cycle, and the minimum diameter displayed is 4-5mm.

2. Follicle growth rate:

Ultrasound can reveal small follicles in the ovaries on the 3rd to 5th day of the menstrual cycle. These follicles gradually grow larger, reaching their largest size on the 14th day on average, and ovulation can occur. From the 5th day of menstruation to before ovulation, the primary follicle grows an average of 1.5mm per day; before the 10th day, it grows an average of 1.2mm per day; 4 days before ovulation, it grows an average of 1.9mm until the follicle matures.

Mature follicles may show the following characteristics:

① The follicle is round or oval, with a diameter of 15-30mm (21.2+-0.53mm). The follicle is echo-free, clear and pure, with clear boundaries and thin walls. ② One day before ovulation, 20% of mature follicles can be seen in the cumulus image, which appears as a short and strong echo near the wall of the follicle. One of the steps in follicle monitoring examination.

3. Ultrasound image of ovulatory follicles near ovulation:

① The appearance rate of cumulus ova is about 20%, mostly appearing in 18mm mature follicles, and ovulation is predicted to occur within 24 hours. ② The sonic ring around the follicle is formed as the LH value rises, the membrane tissue edema, and the granulosa cells separate from the theca cells. Ovulation is predicted to occur within 24 hours. Ultrasound currently shows that the chance is very low. ③ The granulosa cells of the follicle wall are completely separated from the bottom layer of the membrane tissue, and the follicle wall appears serrated.

The above is the chance of pregnancy through follicular puncture that I introduced to you. If a woman has infertility, she should first undergo a systematic examination to avoid certain diseases. Then she can choose follicular puncture to assist pregnancy, which can effectively increase the chance of pregnancy. Finally, I wish you a speedy pregnancy.
