Further evaluation of the split ejaculate for artificial insemination

D Propping, T Katzorke, P F Tauber

    European Journal of Obstetrics, Gynecology, and Reproductive Biology

    Summary

    Using the best semen fraction for artificial insemination with husband semen (AIH) did not significantly improve pregnancy rates in men with oligozoospermia or oligoasthenozoospermia. This suggests underlying, unidentifiable sperm pathologies in cases of long-standing seminal deficiency.

    Area of Science:

    • Reproductive Medicine
    • Andrology
    • Infertility Research

    Background:

    • Artificial insemination with husband semen (AIH) is a common treatment for infertility.
    • Previous studies on AIH efficacy have yielded varied conclusions due to diverse patient indications.
    • Oligozoospermia and oligoasthenozoospermia are common causes of male infertility.

    Purpose of the Study:

    • To evaluate the effectiveness of using the best split ejaculate fraction for AIH in couples with male factor infertility.
    • To determine if optimizing semen quality through fraction selection improves pregnancy rates in cases of oligozoospermia or oligoasthenozoospermia.

    Main Methods:

    • Study included 55 couples with male partners diagnosed with oligozoospermia or oligoasthenozoospermia.
    • Exclusion criteria included female anatomical abnormalities.

  • AIH was performed using the best split ejaculate fraction of semen.

    • Main Results:

    • Despite seminal parameters in the fertile range for the best split fractions, the achieved pregnancy rate was 18% (10/55 couples).
    • This pregnancy rate was comparable to historical data using whole ejaculates for AIH.
    • Spontaneous pregnancy rate after treatment cessation was 13% (6/55 couples).

    Conclusions:

    • Utilizing the best split ejaculate fraction for AIH in oligozoospermic or oligoasthenozoospermic men did not significantly enhance pregnancy outcomes.
    • The findings suggest that men with chronic seminal deficiencies may produce spermatozoa with sub-microscopic pathologies affecting fertility.
    • Further research is needed to identify and address these unobservable sperm defects.
