A team of medical professionals will use a fine needle to extract semen from the epididymis or aspirate the testicle to select the strongest and most sterile sperm cells in a standardized and sterile laboratory under appropriate temperature and humidity control.
It is for sperm cells to survive, not become infected and not deteriorate, to minimize the risk of sperm cell failure and to either freeze or fertilize the eggs of the most fertile female.
Sperm cells are naturally infused with eggs for efficient fertilization and embryo cell division.
- PESA (Percutaneous Epididymal Sperm Aspiration) is the use of a very small needle designed to be used in this procedure through the skin of the scrotum into the epididymis and aspirating the sperm cells. This method produces quality semen and sperm cells. The results are better and more visible than TESA.Usually, PESA takes about 10-20 minutes with a topical injection or deep sedation before the procedure. You only need to recuperate for about 1 hour and then you can go home.
- TESA (Testicular Sperm Aspiration) is a needle specifically designed for this procedure. It is the use of a needle through the skin of the testicle to aspirate the sperm cells. In some cases, some tissue from the testicle will be aspirated through the process of selecting sperm cells from these tissues. TESA requires anesthesia prior to the procedure. There may be some pain that gets better within 3 days.If you are sterile or permanently sterilized, you can have children with PESA and TESA.
In this case, there are two reasons:
- Infertility due to blocked sperm ducts (Vas Deferens & Epididymis)
- Permanent sterilization (by cutting and tying both sides of the spermatic duct)
Our expert medical team at IVF & Woman Clinic recommends TESA in case of male infertility or permanent sterilization (by cutting and tying both sides of the epididymis) but not more than 10 years. Sterilization for more than 10 years, our medical team will not recommend TESA because the chances of a successful pregnancy are very low. In some cases, for men over 60 years of age, the medical team may recommend PESA.
PESA and TESA suitable for which male problem?
- Those who are infertile due to health and age factors
- Men have sperm quality problems such as low quantity, abnormal shape, poor motility, etc.
- Suspected sterility or obstruction of sperm ducts (Vas Deferens & Epididymis)
- Permanent sterilization (by means of cutting and tying both sides of the sperm duct) but wanting to have children later.
