With the increasing competition and life pressure in today's society, many eligible couples are finding it increasingly difficult to conceive. Therefore, many couples preparing for pregnancy choose to use ultrasound to monitor follicular development and arrange for sexual intercourse to promote pregnancy. So, if ultrasound is used to monitor follicle development, how does it indicate ovulation? Next, this article will introduce it to everyone.
How does ultrasound display ovulation
If ultrasound monitoring shows that mature follicles suddenly disappear, there is a small amount of fluid accumulation in the pelvic cavity, and there is corpus luteum formation, it indicates ovulation has occurred. At the same time, it is important to note that transparent vaginal discharge and strong positive ovulation test results during ovulation indicate that ovulation may occur within the next 24 hours.
When is the best time to monitor ovulation with ultrasound
Ultrasound monitoring of ovulation is usually done through vaginal ultrasound. When to do monitoring is very important because we need to be able to grasp the pattern of ovulation while minimizing the number of tests. Therefore, for the first cycle, taking the 28 day menstrual cycle as an example, the ideal monitoring should be as follows:
1. On the 7th day of menstruation, perform an ultrasound to observe the simultaneous development of multiple follicles and the diameter of larger follicles.
2. The second ultrasound around the 10th day of menstruation can show 1-2 dominant follicles and calculate the growth rate of follicles.
3. The third 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, the ultrasound will show a sonorous ring around the follicle, and an experienced technician will tell you that the follicle should ovulate within 24 hours.
4. The fourth ultrasound should be performed around the 14th day after ovulation, when the follicles have disappeared or significantly shrunk by more than 5mm, and liquid dark areas of 4-6mm or even more can be seen in the uterine and rectal crypts. Due to some individuals, although follicles can grow, they cannot ovulate, such as in anovulatory luteinization syndrome, where follicles can grow over 30mm or even larger but do not ovulate, and therefore cannot conceive.
The above is the relevant introduction about how ultrasound displays ovulation. I believe that after reading the above introduction, everyone has a general understanding. At the same time, experts also remind that during the preparation period for pregnancy, it is better to avoid using ultrasound as much as possible. Although it can visually, directly, and accurately see ovulation, there are also many hazards. As long as the detection can achieve the purpose of the examination to the minimum extent possible, it is sufficient.
