What is PESA?
PESA (Percutaneous Epididymal Sperm Aspiration) is a sperm retrieval procedure used alongside ICSI or an IVF procedure in case the man has no sperm in his ejaculate.
PESA is a less invasive procedure than MESA as it is performed without incisions in the skin. PESA is often used as a first choice for one ICSI cycle.
How is PESA carried out?
A thin needle is inserted into the epididymis, the place where sperm are stored in the scrotum, which removes the fluid inside.
Between 10 and 20 million sperm are collected from one or both testicles.
The sperm are used in the ICSI process.
Extra sperm may be cryo-preserved for use in future cycles on ICSI.
Who is a suitable candidate for PESA? Men have no sperm in the ejaculate, for a number of reasons:
A congenital defect means they are born with no vas deferens
The vas deferens is blocked
They have had a vasectomy.
What are the chances of success with PESA?
According to the Center for Reproductive Health, PESA results in pregnancy rates of 24 percent compared to 50 to 52 percent with MESA and IVF.
What surgeon performs PESA?
PESA is normally carried out by a consultant urologist.
