Sperm Motility Affected By Advanced Technologies (Mobiles-Laptops) Leading Lifestyle and Environmental Causes of Low Sperm Count


Authors: Sai Krishna. G, Prem Kumar.P, Bhavani Ramesh.T

Abstract: The use of laptop computers wirelessly connected to local area networks (Wi-Fi) has increased dramatically in recent years. People using Wi-Fi may be exposed to radio signals. The use of portable computers (connected via Wi-Fi) on the lap exposes the genital area to radio frequency electromagnetic waves (RF-EMW) and high temperatures. It has been postulated that declines seen in male fertility over recent years may be related to various environmental factors, including RF-EMW. The effects of extremely low frequency magnetic fields may be associated with oxidative damage of cellular structures and molecules. Oxidative damage to spermatozoa could affect motility or damage DNA. Spermatozoa  in  warm-blooded  animals,  including  humans,  spend  their  entire  life  span  inside  the  male  and  female  genital tract-an environment that consistently remains at body temperature (37 °C). Human sperm that is ejaculated into the female genital   tract   retains   its   fertilizing   capacity   for   up   to   85   hours. Progressive    sperm    motility  is  important   in  evaluating  the  fertility  potential  of  spermatozoa,   and   a  prerequisite  for fertilization in humans. Sperm motility depends on a number of factors, including the temperature.
