Summary
Platelet-rich plasma (PRP) shows the most promise for treating thin endometrium, significantly improving both endometrial thickness and clinical pregnancy rates in assisted reproductive technology (ART). Further research is needed to optimize its use.
Area of Science:
- Reproductive Medicine
- Gynecology
- Infertility Treatment
Background:
- Thin endometrium affects 1-2.5% of assisted reproductive technology (ART) cycles.
- Current treatments for thin endometrium have varied and limited efficacy.
- Effective interventions are needed to improve ART outcomes.
Purpose of the Study:
- To systematically compare the efficacy of different interventions for thin endometrium.
- To evaluate improvements in endometrial thickness and clinical pregnancy rates.
- To guide clinical practice for thin endometrium treatment.
Main Methods:
- Network meta-analysis of 18 randomized controlled trials (RCTs).
- Included interventions: oral aspirin, Ding Kun Dan, intrauterine platelet-rich plasma (PRP), intrauterine granulocyte-macrophage colony-stimulating factor (G-CSF), intramuscular recombinant human growth hormone (rhGH), and neuromuscular electrical stimulation (NMES).
- Bayesian methods used for analysis, with Surface Under the Cumulative Ranking Curve (SUCRA) for ranking effectiveness.
Main Results:
- All interventions improved endometrial thickness compared to controls.
- Top interventions for thickness: G-CSF (SUCRA 78.48%), aspirin (SUCRA 70.89%), and PRP (SUCRA 68.14%).
- PRP (SUCRA 80.12%) was most effective for clinical pregnancy rates, followed by aspirin (SUCRA 70.29%) and Ding Kun Dan (SUCRA 62.79%).
Conclusions:
- Platelet-rich plasma (PRP) demonstrates significant potential for treating thin endometrium.
- PRP offers advantages in both endometrial thickness and clinical pregnancy rates.
- High-quality RCTs are recommended to further validate and optimize PRP interventions.
