Patient's question:
Married for three years now, still infertile, after examination it was found to have ovulation disorderDoctor's answer:
1) Basal body temperature (BBT) monitoring: Generally, basal body temperature rises 2-3 days after ovulation, with some cases showing an increase on the day of ovulation. The increase in temperature is usually greater than 0.3 degrees Celsius. BBT monitoring is simple and cost-effective, but it is not accurate in predicting ovulation, with an error margin of ±4 days.2) Cervical mucus examination: During the second half of the menstrual cycle, 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 phase. 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 follicle monitoring: Ultrasound can detect follicles as small as 2-4 mm. Starting from day 9 of the menstrual cycle, observe once every 1-3 days. Through continuous observation, it is possible to see the follicle gradually grow and migrate toward the surface of the ovary. An dominant follicle can be identified between days 9-12. Just before ovulation, the follicle grows by 2-3 mm per day. A mature follicle is typically 18-24 mm in diameter and located on the surface of the ovary.
