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 techniques of TESE/PESA are now available in our hospital to aspirate the sperm from those men who find it hard to do it.
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.
