Achieving Pregnancy Using Primary Care Interventions to Identify the Fertile Window

Area of Science:

• Reproductive endocrinology and fertility studies.
• Natural family planning and fertility awareness methods.

Background:

• Identifying the fertile window is crucial for conception.
• Natural fertility indicators include hormonal monitoring and cervical mucus changes.
• Optimizing intercourse timing can enhance pregnancy rates.

Purpose of the Study:

• To evaluate the effectiveness of achieving pregnancy using focused intercourse within the fertile window.
• To compare different natural fertility indicators for identifying the fertile phase.

Main Methods:

• A 24-cycle prospective effectiveness study involving 256 North American women (aged 20-43).
• Participants used electronic hormonal fertility monitoring, cervical mucus monitoring, or both, via a web-based tracking system.
• Pregnancy outcomes were validated by nurses, and pregnancy rates were determined using survival analysis.

Main Results:

• An overall pregnancy rate of 78 per 100 women was observed within 12 menstrual cycles.
• The hormonal fertility monitor group achieved a 12-cycle pregnancy rate of 83 per 100 women.
• Pregnancy rates reached 100% at 24 cycles for women using the hormonal fertility monitor.

Conclusions:

• Hormonal fertility monitoring alone provides the most accurate natural estimation of the fertile phase for conception.
• Focused intercourse timed with the fertile window, particularly when identified by hormonal monitoring, is beneficial for achieving pregnancy.
