Nowadays, many people who are infertile or have difficulty conceiving use B-ultrasound to monitor the development of follicles. This is because B-ultrasound is the most direct, accurate, intuitive, and almost harmless to adult women. It can monitor the development of follicles, ovulation, etc. However, considering the potential threats of B-ultrasound's cavitation effect, thermal effect, and mechanical effect of ultrasound, it is better to do it as little as possible, including during pregnancy. It is enough to achieve the inspection purpose to the minimum extent possible.

When is the best time to monitor ovulation with ultrasound?

B-ultrasound monitoring of ovulation is usually done by vaginal B-ultrasound. When to do monitoring is very important, because we need to be able to grasp the law of ovulation and do as few checks as possible. Therefore, for the first cycle, taking the 28-day menstrual cycle as an example, the ideal monitoring should be as follows:

1. Around the 7th day of menstruation, do a B-ultrasound to understand whether there are multiple follicles developing at the same time and the diameter of the larger follicles.

2. The second B-ultrasound is done around the 10th day of menstruation, during which 1 to 2 dominant follicles can be seen and the growth rate of the follicles can be calculated.

3. The third B-ultrasound is just before ovulation. If you don't know how to calculate before ovulation, you can follow the growth rate of the follicle of 2mm per day to see when the follicle reaches a size of 1.9-2.0cm. Generally speaking, it should be around the 13th day of the cycle. At this time, a sound-transparent ring will appear around the follicle on the B-ultrasound. An experienced technician will tell you that the follicle should ovulate within 24 hours. In this way, you can see the size of the follicle before ovulation and calculate the actual growth rate of the follicle after the 10th day. An experienced technician can also tell you the quality of the follicle development. For example, if the follicle is relatively round, the follicle wall is relatively thin, the sound transmission inside the follicle is good, and it protrudes to one side of the ovary, the follicle is of high quality and the chance of pregnancy is also high. If during the monitoring process, the growth of the follicle slows down or gradually becomes smaller, the edges shrink, and the translucency decreases, the quality of the follicle is not high, and the follicle may even atrophy and not ovulate.

4. The fourth B-ultrasound should be done just after ovulation, around the 14th day. The follicle has disappeared or significantly shrunk by more than 5mm, and a liquid dark area of ​​4 to 6mm or even more can be seen in the uterine rectal crypt. For some people, the follicles can grow but cannot ovulate, such as unluteinized ovarian syndrome. The follicles can grow to more than 30mm, or even larger, but they do not ovulate, and therefore cannot become pregnant. Therefore, when the ovulation time comes, ovulation monitoring should be done.

The above is an introduction to the best time to monitor ovulation using B-ultrasound. I believe that after reading the above introduction, you already know when is the best time to monitor ovulation by B-ultrasound. From the above introduction, we can understand that there are four main optimal times for B-ultrasound monitoring of ovulation, and the best time for B-ultrasound monitoring of ovulation is mainly determined by the menstrual cycle.
