Requesting a second semen sample within an hour can significantly improve sperm quality for assisted reproduction. This method is valuable for males with poor semen characteristics or no motile sperm in the initial sample.

Area of Science:

  • Andrology
  • Reproductive Medicine
  • Sperm Analysis

Background:

  • Assisted reproduction programs often encounter challenges with suboptimal semen quality.
  • Severe oligo-terato-astenospermic (OTA) syndrome presents a significant hurdle in male fertility treatments.
  • The quality of a single semen sample can be variable, impacting treatment success.

Purpose of the Study:

  • To evaluate the utility of a second, consecutively collected semen sample in cases of poor initial ejaculate quality.
  • To determine if a second sample improves the chances of successful fertilization in assisted reproduction.

Main Methods:

  • A cohort of 109 males with severe OTA syndrome was studied.
  • Semen volume, sperm count, and motility were assessed in both first and second samples.

  • Paired-sample t-tests were used to compare sperm parameters between consecutive samples.

    • Main Results:

    • 33% of males provided a superior second semen sample, which was then used for fertilization.
    • In 41% of cases where the first sample had no motile sperm, the second sample showed detectable motile sperm.
    • The second sample yielded improved sperm parameters in a significant percentage of males with poor initial quality.

    Conclusions:

    • Collecting a second semen sample shortly after the first is a valuable strategy for males with poor semen quality or azoospermia.
    • This approach can optimize sample quality without necessitating complex sperm processing or unnecessary micromanipulation.
    • It offers a practical method to improve fertilization outcomes in assisted reproduction programs.
