Microtese or Micro-Dissection tese is an invasive procedure of locating and extracting sperm from men who are suffering from non-obstructive Azoospermia or severe testicular failure. Microtese is especially helpful to men with these conditions as it allows for identification of very localized areas of sperm production that may have been missed in blind biopsies or needle aspiration techniques.
During this procedure, an expert opens the testes surgically to inspect the tissues under a microscope. Almost the entirety of the testes is carried out to locate healthy areas of sperm production, especially areas that are more likely to produce healthy sperm than others. At this stage, the doctors can collect the sperm for a Natural IVF Cycle or for cryopreservation, to be used later.
Since the procedure is an extensive one, we at SOI understand that the idea of having surgery on an area as sensitive as the testes may be unnerving for a majority of people. That is why the experts at SOI will talk to you about the procedure, walking you through every step of the procedure.
In most cases, a male patient can do with a simple testicular mapping procedure, which is usually performed before Microtese. However, in cases where no sperm is found, the doctors proceed with Microtese, following a certain set of steps.
- The patient is put under general anaesthesia so they are sleeping during the procedure.
- The surgeon makes a small incision of about 2-3 cm in the midline of the scrotum.
- Through this incision, the doctor will then open up your testicles and look under a high
powered microscope to find the tubules inside that are swollen and may contain sperm.
- From one of these tubules, a sample will be collected and sent for further analysis
- The doctor will then close up the incision with a very fine suture that will then dissolve
on its own, and will not leave behind any kind of scaring.
- The sample is then studied under a standard microscope to find sperm, which are then
frozen in liquid nitrogen and either used for a Natural IVF Cycle or preserved for later
Q. How much does Microtese cost?
Microtese, as a procedure, has different results depending on a person’s body. This means that the complications, or ease, depends on the person’s body, which creates a significant difference in the cost of procedure.

Q. How successful is Microtese?
The success rate of Microtese in men depends on the number of biopsies a person has had before. Men with zero biopsies before Microtese have a 68% chance of sperm retrieval. As the number of biopsies increase, the chance falls down to about only 20%. So it would be advised that a person does not go through a biopsy before Microtese.
Q. What is Microtese ICSI?
When the sperm retrieved through Microtese are used for fertilization of an egg inside the cytoplasm, the process is called Microtese ICSI. It is a well-known technique used in IVF.
Q. How successful is Microtese ICSI in couples with non obstructive azoospermia?
There are a number of research studies that take various sets and subsets of observations to answer this question. The most prominent answer depends on the chance of finding the sperm in Microtese. When there is sperm retrieval and a successful IVF-ICSI cycle, the chances of a successful pregnancy stand at about 78%, which is a promising number.
