Ejaculatory duct obstruction is a rare cause of male infertility. Transurethral resection of the ejaculatory ducts (TURED) can improve semen parameters and lead to pregnancy in select cases.

Area of Science:

  • Urology
  • Reproductive Medicine
  • Male Infertility

Background:

  • Ejaculatory duct obstruction (EDO) is an uncommon cause of male infertility.
  • Advancements in high-resolution transurethral ultrasound (TRUS) have increased EDO diagnosis.
  • EDO presents with oligospermia or azoospermia, low ejaculate volume, and potentially dilated seminal vesicles or midline cysts on TRUS.

Purpose of the Study:

  • To review the current literature on ejaculatory duct obstruction.
  • To provide guidance on the diagnosis and management of EDO.
  • To highlight TURED as a potential treatment for specific EDO cases.

Main Methods:

  • Literature review of ejaculatory duct obstruction.
  • Analysis of diagnostic criteria including TRUS findings.

Related Experiment Videos

  • Evaluation of treatment outcomes, particularly transurethral resection of the ejaculatory ducts (TURED).

    • Main Results:

    • High-resolution TRUS aids in diagnosing EDO.
    • Transurethral resection of the ejaculatory ducts (TURED) is effective for central cystic lesions and partial obstructions.
    • TURED has shown significant improvements in semen parameters and successful pregnancies in select patients.

    Conclusions:

    • EDO is a rare but surgically correctable cause of male infertility.
    • Diagnosis requires a high index of suspicion in infertile males with specific clinical and TRUS findings.
    • Further research is needed on diagnostic methods and long-term surgical outcomes of TURED.
