TESE (Testicular Epididymal Sperm Extraction)

TESE, or Testicular Sperm Extraction, is a surgical procedure used to retrieve sperm from the testicles, typically for use in procedures like Intracytoplasmic Sperm Injection (ICSI) during in vitro fertilization (IVF), when a man cannot produce sperm through ejaculation due to azoospermia. 

Here's a more detailed explanation:

• Purpose:

  TESE is a sperm retrieval method used when a man has azoospermia (no sperm in his ejaculate) or when sperm are not present or are of poor quality in the ejaculate. 

• Procedure:

  A small incision is made in the testicle, and a small portion of testicular tissue is removed and examined under a microscope to find and extract sperm. 

• When it's used:

  TESE is often recommended for men with non-obstructive azoospermia (NOA), where sperm production is impaired, but the reproductive tract is not blocked. 

• Alternatives:

  Another sperm retrieval method is testicular sperm aspiration (TESA), which involves aspirating fluid and tissue from the testicle using a needle. 

• ICSI:

  The retrieved sperm are then used in ICSI, where a single sperm is injected directly into an egg to aid fertilization. 

• OncoTESE:

  In the context of cancer treatment, "oncological testicular sperm extraction" (oncoTESE) refers to TESE performed before gonadotoxic treatments (like chemotherapy or radiation) to preserve sperm for future use. 

• Post-treatment TESE:

  Another type of TESE, "postgonadotoxic treatment TESE," is performed after gonadotoxic treatments to collect sperm for cryopreservation. 

• MicroTESE:

  A more refined version of TESE, microTESE, uses a microscope to identify and extract sperm from smaller tubes within the testicular tissue. 

• MESA:

  Microscopic Epididymal Sperm Aspiration (MESA) is another sperm retrieval method that involves aspirating sperm from the epididymis, a coiled tube located near the testicle, under microscopic guidance. 

• PESA:

  Percutaneous Epididymal Sperm Aspiration (PESA) is a procedure where a needle is inserted through the scrotal skin into the epididymis to aspirate sperm. 

• Post-Procedure:

  Patients may experience some discomfort and swelling in the area after the procedure, but painkillers and a scrotal supporter can help manage these symptoms.
