NCT07260773

Brief Summary

This prospective, randomized, double-blind, controlled study will be conducted at Tangdu Hospital, Air Force Medical University. It plans to enroll 128 patients with poor ovarian response for a 2-year study. The primary objective is to investigate the effects of exogenous coenzyme Q10 supplementation as pre-treatment on ovarian function and assisted reproductive clinical outcomes in patients with poor ovarian response. Study Hypothesis: Coenzyme Q10 therapy is expected to effectively enhance ovarian function and improve assisted reproductive outcomes in patients with poor ovarian response, while demonstrating favorable safety profiles.

Outcome Measures

Primary Outcomes (2)

  • Number of oocytes retrieved

    Total number of oocytes retrieved during the oocyte retrieval procedure(unit: count).

    From the start of pretreatment until the IVF oocyte retrieval day (approximately 8 weeks of pretreatment plus one IVF treatment cycle).

  • Rate of Metaphase II (MII) Oocytes

    The proportion of mature oocytes (Metaphase II oocytes) among the total number of oocytes retrieved (unit: percentage).

    From the start of pretreatment until the IVF oocyte retrieval day (approximately 8 weeks of pretreatment plus one IVF treatment cycle).

Secondary Outcomes (10)

  • Total Gonadotropin (Gn) Dose

    From the start of ovarian stimulation until the HCG trigger day (up to approximately 2 weeks).

  • Days of stimulation

    From the start of ovarian stimulation until the HCG trigger day (up to approximately 2 weeks).

  • Peak Estradiol (E2) Level

    Assessed on the HCG trigger 1 day.

  • Cycle Cancellation Rate

    From the start of ovarian stimulation until the scheduled oocyte retrieval day (up to approximately 2 weeks).

  • Fertilization rate

    Day 1 after oocyte retrieval (fertilization assessment)

  • +5 more secondary outcomes

Other Outcomes (1)

  • Incidence of Adverse Reactions

    From the first dose of the study drug until 6 weeks after the first embryo transfer (for clinical pregnancy assessment).

Study Arms (2)

Guidelines for Routine Treatment + Coenzyme Q10

EXPERIMENTAL

Guidelines for Routine Treatment + Coenzyme Q10 (Nengqi Lang, Yunda Pharmaceutical) 30mg orally, 3 times daily, with pretreatment lasting 8 weeks. • ART treatment (in vitro fertilization (IVF)) commences during the first menstrual cycle following completion of treatment.

Dietary Supplement: Coenzyme Q10

Guidelines for Routine Treatment plus placebo

PLACEBO COMPARATOR

Guidelines for Routine Treatment plus placebo, administered for 8 weeks. ART treatment (IVF) commenced during the first menstrual cycle following completion of the treatment.

Dietary Supplement: Placebo

Interventions

PlaceboDIETARY_SUPPLEMENT

Drug A plus placebo, administered for 8 weeks. ART treatment (IVF) commenced during the first menstrual cycle following completion of the treatment.

Guidelines for Routine Treatment plus placebo
Coenzyme Q10DIETARY_SUPPLEMENT

One group received coenzyme Q10 pretreatment, while the other group did not. Following an 8-week pretreatment period, IVF cycles were performed, with regular follow-up evaluations conducted.
