Infertility Is A Major Health Concern

It affects 15% of couples in Canada, with male factor contributing to half of these cases. Advancements in assisted reproduction technologies (ART) have revolutionized the treatment for male infertility and have allowed thousands of men to become biological parents.

Male Factor

Low sperm counts and/or low motility (ability of sperm to move) and/or decreased morphology (normal shape of sperm head/tails) and/or absent sperm in the ejaculate.


Microsurgical testicular sperm extraction (MicroTESE) is a procedure that allows for the removal of tiny volumes of testicular tissue in areas with active sperm production using a microscope.

The sample tissue is then processed by an Embryologist/Andrologist in the laboratory to search for mature sperm. The extracted sperm can be used for a fresh IVF-ICSI cycle, or frozen for future cycles.

The Current Success Rate For Finding Sperm Is Up To 50% Of The Cases

The Procedure

MicroTESE is a day surgery, so you will be able to go home on the same day as your operation.

Post Surgery Minimal amount of pain and discomfort after this surgery can be felt. The scrotum is one of the fastest healing parts of the body. Most men use an ice pack for the first 24 hours after the surgery.

Prescription pain medication can be taken as needed. We ask that men avoid sex, masturbation, or vigorous exercise for at least 10 days after the surgery.

Post Surgery

Minimal amount of pain and discomfort after this surgery can be felt.

The MicroTESE procedure is performed through a very small (3–4cm) incision in the midline of the scrotum. The patient is under general anesthesia (completely asleep) before we start the surgery.

We open the testicles through this incision and look under a high power microscope for areas that may contain sperm. The sample tissue is then processed by an andrology technologist who will examine it for the presence of mature sperm. The extracted sperm can be used for IVF-ICSI.
