    What is MESA?

    Microsurgical Epididymal Sperm Aspiration (MESA) is an IVF procedure, in which sperm from the patient is obtained from the epididymis, a tube at the back of the testicle that stores and carries sperm. If the epididymis itself is blocked or absent, sperm can be extracted from the testicles. MESA is often used for men with no sperm in their semen due to a blockage or an absence of the vas deferens (the tube which leads from the testes). These men may be producing sperm in large numbers, but due to the blockage or absence of the vas deferens, none is seen in the semen. This condition is similar to men who have had a vasectomy.

    The Process of MESA Treatment

    Step 1: Incision
    The physician will provide local anesthesia before creating a small incision to access the epididymis.

    Step 2: Aspiration
    A very tiny needle is passed through the scrotum and into the epididymis, where sperm is aspirated.

    Step 3: Fertilization or Preservation
    The collected sperm are examined and evaluated for its health, strength, and motility. The patient may choose to utilize the sperm to fertilize his partner’s or a donor’s egg. The patient may also choose to preserve the sperm for later use.

    Who should consider MESA?

    • Men with azoospermia (no sperm in ejaculate)
    • Men with obstructive problems due to vasectomy
    • Men with congenital absence of vas deferens
    • Patients with scarred vas deferens
