IVF/ICSI treatments
PESA/TESA
PESA / TESA procedure should be used when there is no sperm in ejaculate (so called ‘azoospermia) confirmed in two independent semen assessments.
The procedure can be done under local anaesthesia or short intravenous sedation. For aspiration of sperm from the epidydymis (so called PESA) as well as for aspiration of sperm directly from the testicles (so called TESA) we use special, fine needles which make the procedure less invasive.
PESA/TESA takes about 15-20 minutes and sperm aspirated during that procedure are usually cyropreserved and are to be used for ICSI (IVF with injection of a single, selected sperm) on the day of the egg collection.
