Regarding Male Infertility

As for the infertility that is caused by sperm depletion and azoospermia, is said to be, and generally higher than what is thought of, 1⁄3 of the entire group is suffering from the condition of male infertility.


In the case of the sperm depletion condition, based on the degree, we can concentrate the sperm and do artificial insemination, and do micro-insemination by injecting the sperm into the egg.

In addition, even in the case where it’s the condition of azoospermia where we cannot find the sperm in the semen analysis, we will look for sperm in the epididymis and the testicles.


In our clinic we are have been doing MESA (epididymal sperm aspiration surgery), and TESE(testicular sperm recovery surgery), and to be able to get as much sperm even if a little, the MD-TESE(testicular sperm recovery surgery by surgical microscope)with the use of general anesthesia.  In order to retrieve the one sperm from a small organization that has been taken from the testes, embryologists will continue to search for hours and then make the ISCI (micro-insemination) with the sperm found.


It is usually a possible day surgery, but it is also possible to be admitted when by the patient’s choice or when the physical condition is not well.  In addition, we are available 24 hours a day if there is a sudden change after surgery.
