The evaluation of sperm morphology as a standard procedure to be included in routine semen analysis is under persistent pressure due to several factors relating inter alia to the changing definition and description for a morphological normal spermatozoon. In addition, the description of different methods for the morphology evaluation process [1], the different ways in which the results are reported by different laboratories [2], and the continued lowering of the cut-off, or lower reference value, in the consecutive World Health Organization (WHO) semen analysis manuals published between 1980 and 2010 changed. An additional factor in the demise of sperm morphology evaluation in the routine Andrology laboratory is the continuing trend of non-adherence in many laboratories to the guideline given in the WHO manual(s) [3].
