Non-surgical testing is designed for men, whose ejaculate does not contain any sperm cells.
At the present time, biopsy of a testicle is indicated for men who were diagnosed with "azoospermia" as a result of spermogram analysis. This test allows to figure out whether the organism of a man produces sperm suitable for fertilization (with IVF ICSI method).
Scientists from the Lyunenfeld-Tanenbaum Institute (Toronto) have developed a biochemical test that can show whether the reception of sperm from the testicles will be successful.
"The advantage of this method is that we can determine if a man has sperm in his testicles without surgical intervention", - Dr. Keith Jarvi commented the work.
Currently, work on adaptation of the testing procedures for their application in infertility treatment clinics is ongoing. "According to optimistic forecasts - this will happen in a year. According to pessimistic - in two years, we are progressing very quickly," - said Dr. Jarvi.
