Smoking can have negative effects on men’s fertility — SEE WHY
Researchers from Sao Paulo Federal University studied the effect of smoking on fertility by comparing the sperm of 20 smokers and 20 non-smokers. They found that smokers' sperm was more likely to have DNA damage, as well as some partially and fully inactive mitochondria . Mitochondria are the parts of the sperm cells that generate the energy needed to complete tasks, such as traveling to the egg for fertilization. Men who smoke also have more flawed acrosomes in their sperm. Acrosomes are located near the heads of sperm cells, and they contain the digestive enzymes needed for the sperm to break down the membrane of the egg cell at fertilization. The scientists also examined 422 proteins in the patients' sperm. Proteins are essential to every cell, playing a role in its structure, function and regulation of cell processes.When comparing the two groups of men, researchers found that one protein was absent from the smoking group, while 27 were underrepresented and 6 were overr...
