Study population: The study cohort will prospectively enroll women undergoing in vitro fertilization and embryo transfer (IVF-ET) treatment at the Department of Reproduction and Genetics, Affiliated Hospital of Shandong University of Traditional Chinese Medicine, from October 2024 to January 2025. This cohort will be stratified into four study groups based on the following criteria in equal proportions. All participants will receive the standard operation protocol for In vitro fertilization and embryo transfer.

Who may be able to join

  • 1. Women who are married and aged between 20 to 45 years, diagnosed with infertility;
  • 2. Individuals undergoing their first or second cycle of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), with a scheduled fresh embryo transfer;
  • 3. Participants must fulfill the diagnostic criteria corresponding to one of the following prognostic categories as determined by the clinician: Normal prognosis, unexpected poor prognosis, poor prognosis of advanced maternal age, or expected poor prognosis.

Who cannot join

  • 1. A body mass index (BMI) of ≥ 35 kg/m²;
  • 2. Participation in cycles involving pre-implantation genetic testing or diagnosis of embryos;
  • 3. Involvement in cycles utilizing frozen gametes;
  • 4. Engagement in cycles that employ donor-derived oocytes;
  • 5. Participation in in vitro maturation cycles;
  • 6.The presence of uterine cavity or endometrial abnormalities, including but not limited to fibroids, endometrial polyps, malformations, adenomyomas, endometritis, endometrial thinning, hydrosalpinx, uterine infections;
  • 7.The existence of contraindications to assisted reproductive technology or pregnancy, such as uncontrolled liver or kidney dysfunction, diabetes mellitus (with glycated hemoglobin ≤ 7% and fasting blood glucose \< 10 mmol/L), hypertension, thyroid disorders, asymptomatic cardiac conditions, moderate-to-severe anemia, malignancies, a history of thromboembolism or thrombosis, severe mental health disorders, acute infections of the urinary and reproductive systems, sexually transmitted infections, and detrimental lifestyle factors including substance abuse. Additionally, exposure to teratogenic levels of radiation, toxins, or medications (such as prednisone, other hormones, adrenaline, antibiotics, or medications for hypertension, cardiovascular issues, or antiviral treatment) during surgical procedures, as well as any physical conditions rendering pregnancy inadvisable, are also considered disqualifying factors.

About this study

Official title: Investigate Differences in SIRT3 Expression in Granulosa Cells and the Levels of Follicular Fluid Metabolites Among Poor Ovarian Responders Subgroups, and Their Association With IVF Outcomes.

The goal of this prospective, observational study is to learn about the pathogenesis and biological target of the subtypes of poor ovarian response (POR) during In vitro fertilization and embryo transfer (IVF-ET). The main question it aims to answer is:

  1. Can the relative expression level of SIRT3 differentiate between POR subtypes, and do these differences reflect distinct metabolic characteristics among the subtypes?
  2. Investigate whether SIRT3 expression levels correlate with clinical outcomes. This study will enroll patients with various POR subtypes and collect discarded follicular fluid and granulosa cells on the day of egg retrieval. IVF outcome information routinely collected in electronic databases will also be recorded. Notably, this is a purely observational study with no additional interventions. Your participation will not alter your clinical treatment compared to other patients.

Secondary outcomes (6)
  1. Positive pregnancy rate

    Serum β-hCG level ≥ 10mIU/mL, 14 days after embryo transfer. [Detected via ELISA]

  2. Embryo implantation rate

    The number of intrauterine gestational sacs observed divided by the number of embryos transferred. [Detected via ultrasound]

    Measured: 3 weeks after the day of embryo transfer

  3. Clinical pregnancy rate

    An intrauterine gestational sac with fetal heartbeat detected by transvaginal ultrasonography. [Detected via ultrasound]

    Measured: 4 weeks after the day of embryo transfer

  4. Number of oocytes retrieved

    The total number of oocytes retrieved in the In Vitro Fertilization and Embryo transfer cycle.

    Measured: Within 1 day after the oocyte retrieval

  5. Average daily dose of gonadotropin per COS cycle

    Average daily dose of gonadotropin per COS cycle

    Measured: Through the process of controlled ovarian stimulation, an average of 10 days

  6. Total dosage of gonadotropin per COS cycle

    Total dosage of gonadotropin per COS cycle

    Measured: Through the process of controlled ovarian stimulation, an average of 10 days

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The relative expression level of SIRT3 mRNA of granulosa cells (time frame: Detected within three days after oocyte retrieval). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06617988, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2026.
