Patient's question:
Do you need to test every day? You need to urinate before testing.Doctor's answer:
1) For patients with irregular menstrual cycles, the initial monitoring time should be adjusted appropriately based on the length of the menstrual cycle. Those with longer cycles should have the monitoring delayed, while those with shorter cycles should have it advanced.2) Based on the previous rate of follicular development, the interval for this monitoring should be adjusted accordingly. For patients with early ovulation of dominant follicles, when the follicle size reaches 14mm or more, the monitoring frequency should be increased. When the dominant follicle matures to a diameter of 18–23mm, basal body temperature (BBT) can be self-measured in natural cycles. If the BBT rises by >0.5°C (approximately 36.7°C or higher), a follow-up ultrasound should be performed to observe whether ovulation has occurred.
3) If no dominant follicle is observed around days 20–25 of the cycle, it can be considered an anovulatory cycle, and consultation with a doctor is necessary for further management. In ovulation induction cycles, human chorionic gonadotropin (HCG) injections are routinely administered to induce ovulation, ensuring successful ovulation, better timing for conception, and enhanced luteal function. The patient and their partner are guided for conception after the HCG injection. A follow-up ultrasound is performed 48 hours after the HCG injection. If the mature follicle has disappeared or collapsed, progesterone should be administered for luteal support for 14 days. If menstruation does not occur 14 days later, further judgment should be made with urine HCG. If HCG is positive, luteal support should be continued until approximately 5 weeks post-ovulation, followed by a vaginal ultrasound monitoring. If pregnancy does not occur in this cycle, the medication can be stopped, and the patient should wait for menstruation to occur. The next ovulation induction cycle should begin on days 1–4 of the following menstrual period.
