Early Prevention and Precision Management of Female Fertility Decline (OvaRePred-Plus)
Development and Evaluation of a Precision Prevention Strategy for Early Female Fertility Decline Based on OvaRePred-Plus: A Multicenter Cluster Randomized Controlled Trial
Female fertility decline has become an important public health issue in China, with a substantial proportion of women of reproductive age experiencing reduced ovarian reserve. However, effective tools for early identification and large-scale prevention of fertility impairment in the general population are still lacking.
This study aims to develop and evaluate a precision prevention strategy for early female fertility decline based on the OvaRePred-Plus model, which integrates ovarian reserve markers, lifestyle factors, and reproductive health indicators. A multicenter, cluster randomized controlled trial will be conducted across six medical centers in China, enrolling women aged 20-40 years identified as having early signs of fertility decline.
Participants will be allocated to either an intervention group receiving a comprehensive health management program (including dietary optimization, nutritional supplementation, physical activity, and sleep improvement) or a control group receiving routine clinical care. The intervention will last for 12 weeks.
The primary outcome is the change in fertility score assessed by the OvaRePred-Plus model. Secondary outcomes include changes in ovarian reserve markers (e.g., AMH), menstrual status, ultrasound parameters, and reproductive outcomes.
This study is expected to provide evidence for a scalable and cost-effective strategy for early prevention and management of female fertility decline.

|---|---|
|
実験的:Intervention Group
Participants receive a 12-week comprehensive lifestyle intervention program, including dietary optimization, nutritional supplementation (vitamin C, vitamin D, and folic acid), structured physical activity (≥150 minutes/week of moderate-intensity exercise), and sleep improvement (7-8 hours per night).
The program is supported by biweekly health education sessions and digital monitoring tools.

A 12-week structured lifestyle intervention program designed to improve female reproductive health.
The intervention includes dietary optimization (high-protein, high-vitamin, low-fat diet), nutritional supplementation (vitamin C, vitamin D, and folic acid), structured physical activity (at least 150 minutes of moderate-intensity exercise per week), and sleep improvement (7-8 hours per night with optimized sleep timing).
The program is supported by biweekly health education sessions and digital monitoring tools to enhance adherence and behavior change.

アクティブコンパレータ:Control Group
Participants receive routine clinical care, including medical history assessment, hormonal testing, ultrasound evaluation, and general health advice without a structured lifestyle intervention program.
