TESA, TESE & PESA Procedures(for male infertility).

TESA (Testicular Sperm Aspiration), TESE (Testicular Sperm Extraction), and PESA (Percutaneous Epididymal Sperm Aspiration) are procedures used to retrieve sperm from men with certain types of male infertility issues:

  1. TESA (Testicular Sperm Aspiration): TESA involves inserting a needle into the testicle and aspirating fluid and tissue to retrieve sperm cells. It is typically used when there is a blockage preventing sperm from being ejaculated or in cases of non-obstructive azoospermia, where the testicles produce few or no sperm.
  2. TESE (Testicular Sperm Extraction): TESE is a surgical procedure where a small incision is made in the testicle to extract tissue samples containing sperm. It is used similarly to TESA for retrieving sperm in cases of obstructive or non-obstructive azoospermia, depending on the specific conditions of the patient.
  3. PESA (Percutaneous Epididymal Sperm Aspiration): PESA involves using a needle to aspirate sperm directly from the epididymis, a small tube attached to the testicle where sperm mature. This method is used primarily for men with obstructive azoospermia, where sperm are produced but are blocked from entering the ejaculate.

These procedures are part of assisted reproductive techniques like IVF and ICSI (Intracytoplasmic Sperm Injection), allowing couples with male infertility issues to achieve pregnancy using retrieved sperm for fertilization.
