It is amazing on how many false-positive or false-negative results of simplified “spermiograms” in the last 18 years we have had the difficult task to confront and disagree, unfortunately the majority of them performed in Clinical Analyses General Laboratories, so common in Brazil, not always familiarized with sperm physiology or andrology lab techniques widely disseminated by World Health Organization manuals. Surprisingly, wrongful results are not unusual from single semen analyses performed in “andrology” facilities located inside some Centers with eyes mainly focused in performing Intra-Cytoplasmic Sperm Injection (ICSI) as the silver-bullet for dealing with male infertility.
