Testicular Sperm Extraction (TESE)

While men with low sperm concentrations can often succeed with IVF through ICSI, others may experience an absence of sperm in the ejaculate, yet they may still have sperm in their testicles. That's when Testicular Sperm Extraction (TESE) can make a difference in the outcome of fertilization.

TESE is a surgical sperm retrieval procedure performed by experienced urologists in conjunction with laboratory experts. It involves the removal of a small amount of testicular tissue or epididymal fluid (under a local anesthesia or light sedation), which is then immediately transported to the IVF laboratory for processing. An embryologist then extracts the sperm from the biopsy specimen to utilize for ICSI and IVF.

Men lacking sperm in their ejaculate are often categorized with one of the following:

These groundbreaking advances have dramatically reduced the need for donor sperm and vasectomy reversals, as tapping the reservoir in the testicle has become highly effective over the past few years. Extracted sperm is typically cryopreserved for any subsequent IVF and ICSI procedures.
