TESA (Testicular Sperm Aspiration) is a process for recovering sperm from the testes of a male. If any male has non-obstructive azoospermia then TESA is best for them. The cost of TESE depends upon the cause and time. If your treatment will finish in a shorter time then you have to bear little amount. In case of a longer time period, you may have to bear the amount according to the tests and treatment. You can take advice at the infertility clinic for more information!
