Summary

Transperineal needle electroejaculation successfully obtained semen in 11 of 12 anejaculatory men. This novel technique yielded comparable results to the transrectal probe method for semen retrieval.

Area of Science:

  • Reproductive Medicine
  • Urology
  • Andrology

Background:

  • Anejaculatory infertility affects numerous men, necessitating effective sperm retrieval methods.
  • Conventional electroejaculation techniques can be invasive or require specialized equipment.

Purpose of the Study:

  • To evaluate the efficacy of transperineal needle electroejaculation for semen retrieval in anejaculatory men.
  • To compare the effectiveness of transperineal needle electroejaculation with the transrectal probe method.

Main Methods:

  • Transperineal needle electroejaculation was performed using a Digistim nerve stimulator and Teflon-coated needles in 12 anejaculatory males.
  • Semen samples were collected and analyzed.
  • A subset of participants also underwent electroejaculation using a transrectal probe for comparative analysis.

Main Results:

  • Successful semen retrieval was achieved in 11 out of 12 (91.7%) anejaculatory men using the transperineal needle technique.
  • Semen parameters obtained via transperineal needles were comparable to those obtained using the transrectal probe.
  • The Digistim nerve stimulator and Teflon-coated needles proved effective for this procedure.

Conclusions:

  • Transperineal needle electroejaculation is a highly effective method for obtaining semen in anejaculatory men.
  • This technique offers a viable alternative to transrectal electroejaculation with comparable semen quality.
  • Further research may explore the long-term efficacy and patient tolerance of this minimally invasive approach.
