Do I need to hold my urine to check my ovarian follicles?

Nowadays, many women test their follicles during ovulation in order to prepare for successful pregnancy. In this way, you can understand the development of the follicles very well and then conceive at the most appropriate time. In addition, women who need in vitro fertilization or artificial insemination will also have their follicles checked. So, do you need to hold your urine when checking follicles? More on this below!

1. Do I need to hold my urine during follicle monitoring?

You need to hold your urine when checking ovarian ovulation through B-ultrasound. Because the bladder will only expand after holding urine, this will not affect the examination of the uterus. The timing for follicle testing is also important. You can start testing around the tenth day after your period. And you cannot simply test for a week. It is best to monitor continuously for a week, checking every 2 to 3 days. However, if your menstrual periods are irregular, you may need to test more frequently. A woman's body temperature will also change during ovulation, so you can also check your body temperature at the same time.

2. Suitable population for follicle monitoring

1. Patients with infertility caused by endocrine factors: such as menstrual disorders, anovulatory menstruation, amenorrhea, ovarian dysfunction, etc.; they need to understand the development of follicles, including natural menstrual cycles and drug-induced ovulation cycles.

2. Patients with infertility caused by polycystic ovary syndrome: Polycystic ovary syndrome is a common ovulation disorder. The cause of the disease is relatively complicated. In addition to amenorrhea or irregular menstruation caused by anovulation, other signs such as hirsutism and obesity may also occur. Through follicle monitoring, it can be found that the ovaries are characterized by multiple small follicles that cannot develop to maturity.

3. Patients with infertility caused by premature ovarian failure: A common disease in which ovarian dysfunction leads to anovulation is premature ovarian failure. Premature ovarian failure means that the follicles in the ovaries have been exhausted, and detailed diagnosis is required through follicle monitoring.

4. Infertile patients with habitual miscarriage: Follicle monitoring is needed to understand the growth and development of follicles, follicle rupture and corpus luteum formation, which plays a key role in determining the specific cause of miscarriage and clinical treatment plan.

3. Criteria for dominant follicles

The so-called dominant follicle in medicine is a follicle that is larger than 10mm and smaller than 18mm on ultrasound.

In the first half of the menstrual cycle - the follicular phase, under the action of estrogen, several follicles usually develop and grow gradually. Through B-ultrasound monitoring, we found that near ovulation, there is always one follicle that is the largest, and after it ruptures and ovulates, the other follicles are absorbed and disappear one after another. We call this follicle with the largest head and the most mature development the dominant follicle.

If the normal menstruation is 30 days, the follicle that grows to more than 1.0 on the tenth day of menstruation can be considered the dominant follicle. The dominant follicle is of great significance in infertility treatment, and it serves as a beacon to guide treatment.
