TESA-PESA-MESA Treatment: Sperm Extraction Procedures

What are these TESA and PESA procedures?

Some of the causes of male infertility are non availability of normal viable sperms in the ejaculate for IVF treatment.

Some of the reasons could be:

  • Azoospermia (No sperms)
  • Low sperm count (Oligospermia),
  • Low sperm motility (asthenospermia).
  • Tesa and Pesa treatment includes the procedures to recover sperms through the minor medical surgical process.

    Sperm Extraction Procedures:

    PESA (Percutaneous Epididymal Sperm Aspiration)

    PESA treatment is a surgical procedure which involves the use of needle and syringe technique as for a needle biopsy, but the needle is directly placed into the epididymis. This often gives good results if there is a blockage in the vas deferens but the testis is producing sperms.

    TESA (Testicular Sperm Aspiration) and TESE(Testicular Sperm Extraction)

    TESA Treatment is similar to a needle biopsy but involves placing a needle attached to a syringe through the skin of the scrotum, and simply sucking out the fluid from the testicle.
