TESA / PESA Treatment Pune
Sometimes fertilisation is prevented because of poor ejaculation or because the sperm lacks progressive motility required to break through the outer membrane of the egg. Until recently, the only way for men with irreversible obstructions to become biological fathers was to undergo a complex open surgical operation known as Micro Epididymal Sperm Aspiration (MESA). Thanks to new medical technologies, we now have much easier methods like TESA and PESA to overcome male infertility problems. Diagnostic TESA/PESA technique is sometimes recommended at least 3 months before the planned IVF/ICSI treatment cycle. If motile sperm is recovered, either from the epididymis or testes, the sample can be frozen under cryopreservation for several treatment cycles. This saves patients the need for a repeat procedure. When IVF and ICSI treatment is planned, male patients are booked for a back up procedure of TESA/PESA technique on the day of their wife’s egg collection. This is a precautionary measure taken in case the frozen sperm/tissue does not survive the thawing process after cryopreservation. For more informtion visit our IVF treatment centre in Pune.
PESA (Percutaneous Epididymal Sperm Aspiration) PESA is simple technique of recovering sperm by passing a needle into the epididymis through the skin. This is performed under sedation, or general anaesthesia on a day-patient basis. The sperm retrieved is specially prepared and then individually injected directly into eggs recovered for ICSI. The PESA technique To buy viagra care buy viagra online wipe generic cialis of so buy cialis online hair. has many advantages and is much more acceptable to patients since they can usually return to work the next day and generally have no anxiety about repeating the process if required. Chances of pregnancy after the application of PESA procedure with the ICSI technique in couples with obstructive azoospermia are mainly affected by: • The age of the woman producing the eggs • The number of mature eggs available for microinjection • The number of embryos transferred PESA is indicated to: • Men with failed vasectomy reversal • Those born with an absent deferens • Those with other irreversible obstructions of the genital tract
TESA (Testicular Sperm Aspiration) Sometimes a man does not have any sperm in the semen (azoospermia). This means that he does not have an obstruction but rather a testicular failure. The testes might still produce some sperm but they may be in an insufficient number that do not appear in the semen. However, they can still be recovered from the testes. TESA is a simple procedure that involves direct removal of the sperm from the testicles using local anesthesia. Patients usually return to work the following morning after the procedure. It is carried out as an outpatient procedure under intravenous sedation or local anaesthesia or a combination of both. The procedure does not take long. Some patients might have ‘islands’ of sperm producing tissue within the testicle. The TESA technique is more likely to pick up such ‘islands’ of tissue as compared to open testicular biopsy. TESA is also indicated to patients in rare cases when PESA has not been successful due to damage or scarring of the epididymis or defective sperm production in the testes which can hinder fertilisation.
