TESA - Genova


The Basics

TESA or Testicular Sperm Aspiration is an advance technique used to retrieve sperms from the epididymis or testis. TESA is performed on men with deficiency of sperm in their ejaculate, a condition which is also known as azoosperia. In the past the only option for men with azoosperia was to undergo a major reconstructive surgery. Fortunately, with TESA sperms can be easily collected through a minor procedure. These sperms are then injected in the eggs collected from the female through IVF-ICSI (Intra-Cytoplasmic Sperm Injection) enabling men with azoospermia to become biological fathers.

When is TESA used in men?

  • In cases where testicles are not producing sufficient sperm or non-obstructive azoosperia.
  • If the sperm cannot pass through in ejaculation due to a blockage or obstructive azoosperia.

TESA is a minor procedure and considered a breakthrough in fertility treatment. Sperms can be retrieved from testis or epididymis in azoosperia patients where there is no blockage or obstruction. Once the sperms are retrieved, the embryologist can use them for IVF-ICSI procedure.


TESA is only a 10-15minute procedure. Male reproductive consultants at Genova are highly skillful and will perform this procedure using local anesthesia. A needle will be inserted in the testis and aspirating fluid using negative pressure. The embryologist will then process the sample and extract sperm cells in the laboratory. These sperm cells will then be injected into your wife’s eggs through intra-cytoplasmic sperm injection (IVF-ICSI).

Is TESA painful?

TESA is considered a minor procedure and can be performed within 10 minutes. You will be given local anesthesia to minimize discomfort. You will only experience minor pain, which may only last for few hours. Genova reproductive consultants are highly trained and experienced to perform this procedure with minimal pain and discomfort.
