    Split ejaculates significantly improve sperm presence in cervical mucus compared to whole semen in oligospermic patients undergoing artificial insemination. This method enhances sperm count and motility, aiding fertility treatments.

    Area of Science:

    • Reproductive Medicine
    • Andrology
    • Infertility Research

    Background:

    • Oligospermia affects male fertility, characterized by low sperm count.
    • Negative postcoital tests indicate poor sperm-cervical mucus interaction.
    • Artificial insemination is a common fertility treatment.

    Purpose of the Study:

    • To evaluate the efficacy of split ejaculate insemination versus whole semen insemination.
    • To assess sperm presence and motility in cervical mucus post-insemination.
    • To improve outcomes for oligospermic patients with negative postcoital tests.

    Main Methods:

    • 25 oligospermic patients with negative postcoital tests were included.
    • Artificial insemination was performed using both whole semen and split ejaculates.

  • Cervical mucus samples were analyzed for motile spermatozoa 30 minutes post-insemination.

    • Main Results:

    • Split ejaculate insemination showed a 64% improvement in motile spermatozoa in cervical mucus.
    • Whole semen insemination resulted in a 44% improvement.
    • The split ejaculate group had significantly higher sperm count and progressive motility.

    Conclusions:

    • Split ejaculate insemination is a more effective method for improving sperm-cervical mucus interaction in oligospermic patients.
    • This technique enhances the chances of conception by increasing motile sperm in the female reproductive tract.
    • Split ejaculation offers a viable strategy to improve artificial insemination success rates.
