Which sperm retrieval technique uses percutaneous aspiration from the epididymis?

Explanation:
Percutaneous epididymal sperm aspiration uses a fine needle inserted through the scrotal skin to aspirate sperm from the epididymal duct. This approach is the percutaneous method described, distinguishing it from open or microsurgical epididymal retrieval (which requires exposing the epididymis) and from testicular retrieval techniques. The epididymis holds mature sperm, so aspirating from there provides sperm that can be used for assisted reproduction. In contrast, MESA is a surgical epididymal retrieval, TESE retrieves from testicular tissue, and micro-TESE is a refined form of TESE.
