Summary

Electroejaculation successfully retrieves sperm in most anejaculatory men, offering a viable fertility option. Pregnancy rates were achieved through intrauterine insemination and in vitro fertilization, though sperm motility was low.

Area of Science:

  • Reproductive Medicine
  • Andrology
  • Infertility Treatment

Background:

  • Anejaculation, the absence of ejaculation, presents a significant challenge for male fertility.
  • Causes include spinal cord injury and retroperitoneal lymph node dissection.
  • Assisted reproductive technologies (ART) are crucial for achieving fertility in affected individuals.

Purpose of the Study:

  • To evaluate the efficacy of electroejaculation combined with assisted reproductive technologies for treating anejaculatory infertility.
  • To assess sperm retrieval success and pregnancy rates in men with anejaculation.
  • To analyze the quality of electroejaculates.

Main Methods:

  • A cohort of 26 anejaculatory men underwent 84 electroejaculation procedures.

  • Sperm retrieval success was defined by specific sperm count and motility thresholds.
  • Female partners underwent controlled ovarian hyperstimulation for intrauterine insemination (IUI) and in vitro fertilization (IVF).

    • Main Results:

    • Electroejaculation achieved a 92% success rate for sperm retrieval.
    • Intrauterine insemination resulted in a 10% pregnancy rate per cycle, leading to four term infants.
    • One pregnancy was achieved via IVF with micromanipulation, and two couples conceived using donor sperm.

    Conclusions:

    • Electroejaculation provides a promising avenue for fertility in anejaculatory men.
    • Significant asthenospermia (low sperm motility) was noted in electroejaculates, requiring further investigation.
    • Improving understanding of electroejaculate quality may enhance pregnancy outcomes.
