Patient's question:
No children, searched online and thought she had ovulation disorder, wants to get checked, but doesn't know what to check.Doctor's answer:
1. Basal Body Temperature (BBT): Generally, the temperature rises by 0.3 degrees 2-3 days after ovulation. BBT monitoring for ovulation is simple and cost-effective, but it is not accurate in predicting ovulation, with an error margin of ±4 days.2. Cervical Mucus: During the second half of the menstrual period, if the cervical mucus remains fern-like (like the leaves of a fern plant) and lacks elliptical bodies, it indicates anovulation.
3. Endometrial Biopsy: Under the influence of estrogen and progesterone from the ovaries, the endometrium undergoes significant mid-cycle changes during the mid-cycle. If an endometrial biopsy is performed before the menstrual period or within 12 hours of menstruation, and it shows proliferative phase changes, it indicates anovulation.
4. Ultrasound Follicular Monitoring: Ultrasound can detect follicles as small as 2-4 mm. Starting from the 9th day of the menstrual cycle, observe once every 1-3 days. Through continuous observation, you can see the follicle gradually grow and migrate toward the surface of the ovary. An follicle can be identified between days 9-12, and the follicle grows by 2-3 mm per day before ovulation. A mature follicle is 18-24 mm in diameter and located on the surface of the ovary.
