PESA is a treatment used to recover sperm for IVF/ICSI in men who have obstructive azoospermia due to a previous vasectomy or infection. It is performed under local anaesthetic in the operating room or office, and it is timed to coincide with the egg retrieval of their female spouse.
Process for PESA
PESA is commonly done under local anaesthesia, which is administered by injecting the anaesthetic directly into the scrotum. This is done to numb the region and avoid discomfort throughout the process.
After locating the vas deferens, a tiny needle will be placed into the vas deferens or epididymis, and the plunger will be pushed out to aspirate the seminal fluid into the syringe.
The Testes are examined
Before performing the surgery, the doctor disinfects the scrotum with a warm antiseptic swab. After that, the testes are inspected by touching the scrotum for the vas deferens. This is also done to see whether there are any obstructions or anomalies.
Motile Sperm Inspection
An embryologist examines the extracted seminal fluid for moving or motile sperm. PESA will be repeated until enough sperm are discovered if the sperm are insufficient.
