The harm of transvaginal ultrasound for follicle monitoring

Follicle detection is a relatively normal detection method. This type of monitoring has certain benefits for women. However, there are certain precautions when monitoring follicles. If you are not careful and fail to follow the precautions, it may cause some harm. This includes doing vaginal ultrasound during follicle detection. So what are the dangers of doing vaginal ultrasound during follicle detection?

The application of ultrasound in obstetrics and gynecology has a history of nearly half a century. Because ultrasound causes little damage to the human body, it is currently considered to be a non-invasive and repeatable examination with rapid and high accuracy. Today, it has become the preferred imaging examination and diagnostic method in obstetrics and gynecology, providing a more reliable basis for medical treatment and scientific research.

Because the probe of vaginal B-ultrasound is closer to the pelvic organs and does not require the bladder to be filled, the operation is simple, easy, non-invasive and painless. Especially for obese patients or patients with deep pelvic organs, the observation effect is better, and the development of follicles, the thickness of the endometrium and other characteristics can be observed more accurately. It is widely used in clinical practice, and transvaginal ultrasound for follicle monitoring does no harm to the body.

Among the methods of follicle monitoring, B-ultrasound monitoring is the most intuitive one. This monitoring can understand the number, size and development of follicles in a woman's ovaries, but it cannot determine whether ovulation can occur. In addition, women are prohibited from having sex the night before the monitoring to avoid interfering with the monitoring.

Follicle monitoring can start from the 9th to 10th day of the menstrual cycle (note: the day of menstruation is the first day), and be monitored once every 1-2 days with B-ultrasound. Through several B-ultrasound monitorings, you can see the entire process of the follicles gradually growing, maturing and ovulating.

For women with regular menstruation and a cycle of about 28 days, the dominant follicle (>12--15mm) should be monitored on the 9th-12th day; the dominant follicle grows faster, increasing by 2-3mm every day; it usually takes 3--4 days from the monitoring of the dominant follicle to the follicle maturation and ovulation; the mature follicle is generally 18-24mm; but it should be noted that ovulation may occur when the follicle reaches 16mm, or the follicle may have grown to 18mm and ovulated before the next monitoring day. After ovulation, the follicle ruptures, collapses, shrinks in size or disappears. As the follicular fluid is discharged, a certain amount of fluid accumulation can be seen in the pelvic cavity.
