TESA / TESE

What is TESA / TESE?

  • During your semen analysis, if it shows that you don’t have sperm within your ejaculate, there are various techniques of surgically retrieving the sperm, which is known as Surgical Sperm Retrieval (SSR).
  • In such a case the sperm is retrieved from the tissue in a man’s testis using one of the two SSR methods – Testicular Sperm Aspiration (TESA) or Testicular Sperm Extraction (TESE).
  • Testicular Sperm Aspiration (TESA) transpires when a fine needle is inserted into the tests and specimens of tissue carrying sperm are obtained by gentle suction.
  • Testicular Sperm Extraction (TESE) involves taking a biopsy (tissue sample) through a small incision in the scrotum.
  • These procedures are minor day operations and should be performed before beginning an IVF cycle.

Who needs TESA/TESE?

  • If you have no sperm in the ejaculate due to poor sperm production. The problem may be because of previous testicular surgery, prior medical treatment, or a genetic problem.
