Smoking and sperm quality

I do not think these results suggest that women should start smoking when they get pregnant. But, fertility experts who reviewed the new report, published June 12 in Human Reproduction, weren't in full agreement with the findings. He said that while "this important study puts to rest many concerns regarding the effect of lifestyle on sperm quality," it doesn't give would-be fathers a free pass to smoke or indulge in unhealthy behaviors. Men who are trying unsuccessfully to conceive, and those who wish to protect the health of their sperm for the future, should therefore avoid a range of drugs, including alcohol and tobacco.

Not only can smoking have unfavorable effects on male semen parameters, it may also reduce the success of assisted reproduction techniques, such as in vitro fertilization IVF and intracytoplasmic sperm injection ICSI. Previous studies had shown that smoking causes DNA damage to sperm and mitochondria — the energy-producing centres in cells — but this detailed analysis shows how that may occur.
