Microsurgical Epididymal Sperm Aspiration, Mesa

Microsurgical epididymal sperm aspiration (MEDA)

Microsurgical epididymal sperm aspiration (MEDA) is a method of collecting sperm from the epididymis using an aspiration needle. The procedure is performed under general anesthesia.

MEDA is usually used for artificial insemination in cases where, for some reason, the normal removal of sperm from the testicles is disrupted. This may occur due to blockage of the vas deferens due to infection or after a vasectomy.

The resulting sperm undergoes special processing. The most motile sperm are isolated from it. The sperm are then activated using chemicals and used for in vitro fertilization.

Thus, microsurgical epididymal sperm aspiration makes it possible to obtain sperm for artificial insemination in cases where their natural entry into the seminal fluid is difficult.



Sperm aspiration (Microsurgical epididymal sperm aspiration, MESA) is a procedure for removing sperm from the epididymis (epididyma) using a special needle. It is performed for artificial insemination when a man’s normal removal of sperm from the testicle is disrupted.

The procedure is performed under local anesthesia, usually after preliminary preparation of the patient. The doctor uses a special needle that is inserted into the epididyma through the scrotum. The needle is carefully advanced along the vas deferens to collect sperm from the epididymis.

After the sperm is collected, it undergoes special processing. Sperm are selected from the mixture using a microscope and special equipment, after which they are chemically treated to activate their motility.

The treated sperm are then used to artificially inseminate the woman outside the mother's body. This makes it possible to obtain offspring from a man who cannot independently produce sperm in sufficient quantities or with normal sperm motility.



Microsurgical epididymal sperm aspiration (MESA) is the collection of sperm from the epididymis, performed by aspiration under anesthesia in cases of severe disruption of the process of release of gametes from the testicles or after repeated vasectomy during artificial insemination.

The MESA procedure is used to diagnose and treat rare diseases that may prevent sperm from leaving the body. Microsurgery can help the doctor correctly diagnose these rare disorders or adjust the course of treatment and prevent possible complications.

Preparing for surgery includes taking anticoagulants to reduce the risk of blood clotting. The operation is performed by a qualified doctor under general anesthesia: the patient is under deep anesthesia, which makes it painless. He and the surgeon are not in physical contact. Anesthesia prevents pain during the procedure, so the patient can feel good. However, it is best to consult your doctor. MESA usually lasts from 45 minutes to 2 hours depending on the conditions of the operation. The postoperative period includes the possible use of tranquilizers and antibiotics to reduce the risk of infection and reduce pain. The next morning or day after the procedure, the patient should visit his doctor, who will examine, prick his hands and test sensitivity to compression. If the operation went well, the person can go home the next day.
