NCT07550998

Brief Summary

This is a randomized waiting-list controlled crossover trial carried out to investigate the efficacy of traditional Chinese medicine (TCM) for DOR and its potential beneficial effects on fertility. Subjects' (1) Ovarian function (AMH, FSH), (2) Bilateral AFC as shown in pelvic ultrasound, and (3) Traditional Chinese Medicine Symptom Score (TCMSS) will be recorded. It is hypothesized that a 12-week course (5 days medication per week) of TCM herbal therapy for DOR patients will improve one or more of the above aspects when compared to the waiting-list control group.

Outcome Measures

Primary Outcomes (1)

  • serum anti-Mullerian hormone (AMH)

    For all subjects, on the 2nd to 5th days of the menstrual cycle, 3-5 mL of blood will be collected from the arm-cubital vein once. ELISA (enzyme-linked immunosorbent assay) will be adopted to evaluate the level of AMH.

    will be performed on the first menstrual cycle before treatment, and then at week 12 and 24.

Secondary Outcomes (3)

  • Follicle stimulating hormone (FSH)

    will be performed on the first menstrual cycle before treatment, and then at week 12 and 24.

  • Pelvic ultrasound

    This assessment will be carried out at baseline, week 12 and week 24.

  • Traditional Chinese Medicine Symptom Score (TCMSS)

    Up to 18 months

Study Arms (2)

Chinese Medicine herbal treatment group

EXPERIMENTAL

After completing the screening process, Chinese Medicine herbal treatment group will start to receive the Chinese medicine treatment for 12 weeks, during which the TCMSS will be repeated once for every 2 weeks of oral Chinese medicine treatment, for a total of 5 times. At the end of the treatment period, subjects will repeat the same examinations they received before enrollment and enter a waiting list control period for 12 weeks. At the end of the waiting list control period, subjects will repeat the above tests again and undergo IVF treatment after 12 weeks.

waiting-list control group

OTHER

After completing the screening process, waiting-list control group will enter a 12-week waiting list control period. At the end of the waiting list control period, the subjects will repeat the screening procedures they have undergone before enrollment. Upon completion of the screening process, the subject will start to receive Chinese medicine treatment for a period of 12 weeks, during which the TCMSS will be repeated once for every 2 sessions of oral Chinese medicine treatment, making a total of 5 sessions. At the end of the treatment, subjects in Group B will repeat the above tests and receive IVF treatment. The effect of the intervention will be evaluated by comparing the test data between groups and within groups.
