Tesa / Pesa / Mesa

Mesa: 

Symptoms such as obstructive azoospermia (no sperm in the ejaculatory fluid) use a technique known as MESA (microsurgery epididymal sperm aspiration). This includes a single tubular incision by incising the epididymis. Next, the fluid that overflows from the epididymal tubules is aspirated. Due to the large number of blood vessels in the epididymis, this method can result in blood cell contamination, which can impair the ability of sperm to fertilize during in vitro fertilization.

 

PESA : 

PESA is a procedure that can be performed under local anesthesia without knowledge of microsurgery. The procedure involves placing a butterfly needle on the head of the epididymis after administration of a local anesthetic. Apply negative pressure  until you see a milky liquid. The tube is then fixed in place and the system is poured into the collection tube with a sperm medium. This process can be repeated until a sufficient yield is obtained. The percutaneous approach avoids the need to make an incision in the skin, thereby avoiding related pathological conditions such as infection and pain. However, the risk of hematoma is still small.



Tesa :

 

TESA (testicular sperm extraction) is a  TESE (testicular sperm extraction) method in which the testicles are pierced with a needle to suck body fluids and tissues under vacuum (negative pressure). This tissue is then processed and the extracted sperm cells are either ICSI (intracytoplasmic sperm injection), in which sperm are directly injected into the egg, or  the egg and sperm (multiple times) leaving the egg cell in the Petri dish. Fertilize.
