A low sperm count is a common cause of male infertility. This can be due to blocked tubes in the testes or genetic conditions. These options are available to retrieve sperm.

  • TESA - Testicular Sperm Aspiration
  • TESE - Testicular Sperm Extraction
  • PESA - Percutaneous Epididymal Sperm Aspiration
  • MESA - Microsurgical Epididymal Sperm Aspiration
  • IMSI - Intracytoplasmic Morphologically Selected Sperm Injection
  • TESA - Testicular Sperm Aspiration

Testicular sperm aspiration is performed by inserting a needle in the testis and aspirating fluid and tissue with negative pressure. The aspirated tissue is then processed in the embryology laboratory and the sperm cells extracted is used for ICSI.

  • TESE - Testicular Sperm Extraction

TESE is performed under general anesthetic. In this procedure, the doctor uses a thin biopsy needle to remove small tissue samples from several places in one or both testicles. The procedure is performed as an outpatient basis and takes around 10 minutes. This procedure can be repeated if necessary.

  • PESA - Percutaneous Epididymal Sperm Aspiration

PESA does not require a surgical incision. A small needle is passed directly into the head of the epididymis through the scrotal skin and fluid is aspirated. The embryologist retrieves the sperm cells from the fluid and prepares them for ICSI.

  • MESA - Microsurgical Epididymal Sperm Aspiration

MESA is used in conditions like blocked tube in the testes. It involves dissection of the epididymis under the operating microscope and incision of a single tubule. Fluid spills from the Epididymal tubule and pools in the Epididymal bed. This pooled fluid is then aspirated.

  • IMSI - Intracytoplasmic Morphologically Selected Sperm Injection

IMSI is done to examine and select sperm using a high-magnification digital imaging microscope. With the IMSI technique, the doctor will be better able to assess the structure of the sperm and exclude the sperm with suspected variations from being injected into the available eggs.
