TESE/PESA

Some men find it hard to produce sperm in the ejaculate. This condition is called Azoospermia. This can be either due to problems in sperm production itself or due to obstruction to the flow of semen during ejaculation. Reproductive tract obstruction can be acquired – as a result of infection, trauma, iatrogenic injury which can occur during bladder neck, pelvic, abdominal or inguino-scrotal surgery. The advanced TESE/PESA procedures are now available in our hospital to aspirate the sperm from those men who find it hard to do it.

Difference between TESE/ PESA

TESE – During TESE or Testicular Sperm Extraction, your doctor removes a small amount of tissue from one or both testicles; checks it for mature, healthy sperm; and then, if enough healthy sperm are present, uses the sperm in an IVF or ICSI procedure.

PESA – PESA or Percutaneous Epididymal Sperm Aspiration (PESA), does not require a surgical incision. A small needle is passed directly into the head of the epididymis through the scrotal skin and fluid is aspirated. The embryologist retrieves the sperm cells from the fluid and prepares them for ICSI.

Who is suitable for doing TESE/PESA?

  • Men with testicular dysfunction, which may be caused by a genetic disorder or from infection with the mumps virus, prevent normal sperm production.

  • An obstruction of the epididymis or the absence of the epididymis from birth, which is common in carriers of Cystic Fibrosis.

  • Previous infections, injuries, or surgeries that may affect infertility

Advantages of TESE/PESA

Sperm collection directly from the testicles allows for the most complete sperm collection, which is beneficial for people with various health conditions. It is also suitable for those who have had a vasectomy by cutting and tying the sperm ducts on both sides, so PESA/TESE surgery is another good choice.
