Summary

Infertile men can boost fertility by having intercourse daily or twice daily. Sequential ejaculation, pooling samples, significantly increases total motile sperm counts for assisted reproduction.

Area of Science:

  • Reproductive Medicine
  • Andrology
  • Human Fertility

Background:

  • Low total motile sperm counts (TMSC) are a common cause of male infertility.
  • Understanding sperm production and transport is crucial for optimizing conception rates.

Purpose of the Study:

  • To determine optimal intercourse frequency for conception in infertile men.
  • To investigate the impact of sequential ejaculation on TMSC.

Main Methods:

  • A case-control study involving 576 men producing two sequential ejaculates.
  • Comparison of TMSC between first and second ejaculates with varying time intervals.
  • Analysis of TMSC in normospermic, asthenospermic, oligospermic, and oligoasthenospermic groups.

Main Results:

Related Experiment Videos

  • Normospermic men showed a significant decrease in TMSC in the second ejaculate.
  • Oligospermic and asthenospermic men exhibited no significant change or an increase in TMSC in the second ejaculate.
  • Pooling sequential ejaculates significantly increased TMSC across all groups, especially in oligoasthenospermic men (up to 233%).

Conclusions:

  • Sequential ejaculation can improve TMSC in men with oligospermia and/or asthenospermia.
  • Pooling ejaculates or frequent intercourse (daily or twice daily) can enhance fertility potential for assisted reproductive technologies (ART) and natural conception.
