Summary
For male subfertility, the first ejaculate portion offers superior sperm quality. A novel coital technique using this portion has successfully achieved pregnancies in previously infertile couples.
Area of Science:
- Reproductive Medicine
- Andrology
- Human Reproduction
Background:
- Male subfertility affects numerous couples worldwide.
- Standard semen analysis assesses the whole ejaculate.
- Split ejaculate analysis may offer more detailed insights in specific cases.
Purpose of the Study:
- To evaluate the diagnostic value of the first ejaculate portion in male subfertility.
- To introduce and assess a novel coital technique for improving conception rates.
Main Methods:
- Analysis of sperm density, motility, and morphology in whole versus split ejaculate samples.
- Implementation of a coital technique involving withdrawal after deposition of the first ejaculate portion.
- Documentation and analysis of pregnancy outcomes in couples utilizing the new technique.
Main Results:
- The first ejaculate portion demonstrated superior sperm parameters (density, motility, morphology) compared to the whole ejaculate in selected subfertile men.
- The novel coital technique resulted in successful pregnancies in 33 cases over 4 years.
- Pregnancies were achieved in couples with long-standing infertility.
Conclusions:
- Split ejaculate analysis, particularly the first portion, is valuable for assessing male fertility.
- The described coital technique offers a promising approach for overcoming infertility and achieving pregnancy.
