Testicular circulatory isolation (TCI) protects germinal epithelium from chemotherapy damage. This study found TCI safe and well-tolerated in patients undergoing orchiectomy, supporting its use in fertility preservation trials.

Area of Science:

  • Oncology
  • Reproductive Medicine
  • Surgical Techniques

Background:

  • Antineoplastic agents can cause germinal epithelium damage.
  • Testicular circulatory isolation (TCI) is a regional technique to minimize drug exposure.
  • Fertility preservation is a concern for young men undergoing chemotherapy.

Purpose of the Study:

  • To evaluate the technical and anesthetic aspects of TCI.
  • To assess the safety and tolerability of TCI.
  • To support the initiation of TCI trials for fertility preservation.

Main Methods:

  • A modified aortic clamp was used for trans-scrotal TCI.
  • The clamp occluded left testicular blood flow for 1 hour.
  • TCI was performed without pre-medication or anesthesia in 10 patients.

Main Results:

  • Minimal pain and anxiety were reported during TCI.
  • No complications related to TCI were observed in any patient.
  • The procedure was technically feasible and well-tolerated.

Conclusions:

  • TCI is a safe and feasible technique for protecting testicular germinal epithelium.
  • The findings support further clinical trials of TCI in men receiving fertility-threatening chemotherapy.
  • TCI shows promise as a method for fertility preservation during cancer treatment.
