Damaging Effects Of Smoking On Sperm
Posted on Mon Sep 13, 2010Damaging Effects Of Smoking On Sperm
If you need yet another reason for quitting smoking here it is: smoking damages sperm cells and can leave men infertile. A recent study examined the sperm of heavy smokers verses the sperm of nonsmokers and discovered that the men who smoke are less fertile than those who don’t. Sperm cells carry two proteins called protamine 1 and protamine 2. In smokers, sperm cells have too little protamine 2, which then makes them vulnerable to DNA damage, leading to infertility.
