Semen volume and concentration and total sperm count showed significant increases, whereas motility and normal morphology decreased significantly with duration of abstinence. J Assist Reprod Genet. This observation suggests that DNA fragmented spermatozoa can be effectively eliminated from the ejaculate with 1 day abstinence by routinely used sperm wash techniques. The semen volume, in this study, was significantly increased after longer abstinence in days. Placing the laptop on your lap also increases the temperature and can affect sperm quality.
