IVF - MESA / TESE

Even in men with no sperm seen at the time of semen analysis, there may be sperm within the testes. This sperm can be removed by aspiration from the testes or epididymis in procedures called TESE (testicular sperm extraction) or MESA (microscopic epididymal sperm aspiration). TESE and MESA procedures combined with ICSI allow many men, previously considered sterile, to produce children.
