Percutaneous Epididymal Sperm Aspiration (PESA) is a procedure to collect sperm through aspiration from the epididymis, serving to fertilize an ovum by intracytoplasmic sperm injection. This technique applies to patients with infertility due to no sperm but completely normal sperm production, including cases of vas deferens, congenital bilateral absence of vas deferens.
Sperm aspiration from the epididymis is contraindicated in cases of azoospermia but not due to obstruction.

Azoospermia is a condition in which no sperm is found in the semen of a man. The causes of azoospermia are very diverse, it can be because men do not have vas deferens, blocked vas deferens due to infection or sterilization, trauma to the intimate area or impaired ejaculation. Therefore, the technique of sperm aspiration is the solution to infertility treatment to help men become fathers when experiencing azoospermia.The frequency of male patients coming to fertility clinics at Assisted Reproductive Medicine departments is increasing, and cases of no sperm in semen are also relatively common. In these cases, if there is no intervention with sperm aspiration techniques, they must ask for sperm from a sperm bank, so the wife can become pregnant.
