IVF/ICSI (ART)

 

Tesa | Mesa | Pesa

For azoospermic man, when sperm is not present in ejaculate with use of minimal invasive techniques sperm can be obtained. In this way sperm can also be obtained from

  • Vasectomised man, where vasectomy reversal is failed
  • Absence of vas deferens
  • Obstructive azoospermia
  • Non obstructive azoospermia, when sperm production is low
  • There are different sperm retrieval procedures, tailored to the specific couple‚Äôs need.

PESA

Percutaneous Epididymal Sperm Aspiration (PESA) uses a needle to penetrate the scrotal skin and draw a small amount of sperm from the epididymis while Percutaneous Testicular Biopsy removes small cores of testes tissue.

MESA, TESE

The procedures are either performed through the skin (percutaneous) or through a small opening in the skin about 1/2 inch in size. Applying microsurgical techniques in a process known as Microscopic Epididymal Sperm Aspiration (MESA), sperm can be gathered from the epididymis, a sperm rich tube at the back of the testis. Testicular Sperm Extraction (TESE) involves removing small samples of testis tissue for processing and eventual extraction of sperm. Microscopic TESE (MicroTESE) is a very exacting search for sperm under high magnification in cases of extremely low sperm production.

Sperm retrieval procedures do not require an overnight hospital stay and last about one hour. The techniques are typically done at an outpatient surgery center though sometimes an office setting is adequate. Local anesthetic, IV sedation or general anesthesia provide complete pain control during the procedure. Due to the superficial nature of these procedures, patients routinely return back to desk type work in a day or two and disruption of normal activities is quite limited. Patient comfort and technical perfection are paramount.
