The Effects of Short Abstinence Time on Sperm Motility, Morphology and DNA mDamage

Male infertility has been shown to represent 30-40% of the total causes of infertility in couples [1]. The examination of semen following World Health Organization (WHO) guidelines is important and remains the initial screen in the study of male infertility and for the evaluation of spermatogenesis and also has served to provide a standardized approach for the assessment of the fertility potential of semen samples for more than 25 years [2-5]. Therefore the result is used as a guideline for additional examinations and for further treatment of male infertility with regard to determining the preparation period before examination of semen, the WHO guidelines have determined to have the abstinence time before the examination be 2-7 days in order for the concentration of semen, percentage of motility of sperm and percentage of morphology of sperm to be within normal criteria. However, the basis for this recommendation is unclear because no supporting references are provided [5].
