Almost half the NOA-men who undergo TESE/mTESE are negative for spermatozoa at the time of surgical sperm extraction. Thus it is of paramount importance to develop pharmaceutical treatments and surgical approaches that may increase the sperm recovery rate post TESE/mTESE; these strategies will be discussed.
The administration of pharmaceutical agents to men with NOA is controversial and may stimulate Leydig and Sertoli cellular function. Varicocelectomy prior to TESE may result in improved outcomes from TESE and sperm induction within the ejaculate. Finally, intra-operative techniques and embryological factors may affect surgical outcomes. The overall result may be improving the probability of retrieving sperm for ICSI.
