"Can smoking kill the sperm in your body or make it harder for you to have a baby?"

Q.

"If you smoke it won't kill the sperm and make it harder to become pregnant but if the guy smokes it will make it harder for him to make you pregnant because the sperm is not as active and it will make it harder for him to make you pregnant. If you got pregnant and you smoke, it will affect the baby's weight and it will make the chances of having a premature baby increase. It's not good to smoke after the baby's born because although doctors don't know what the exact cause of SIDS is, they still say that the baby receiving second hand smoke is associated with SIDS and could be one of the causes. Let's just say smoking is not good at all."

     A recent study conducted by scientists Canadian mention one more reason not to smoke, because smoking can damage sperm proven passing along genetic damage from a father to his son.

As reported by Reuters on Sunday (03/06), a study conducted on mice showed that smoking causes changes in DNA in sperm cells, where such mutations are known to be permanent.

"" If inherited, these mutations showed that changes can not be restored from its genetic composition, "said Carole Yauk of Toxins and Health Management Division of Environment Canada, who led the study.

"Earlier it was known that pregnant women who smoke can harm their fetuses, and here we show evidence that fathers can potentially damage any potential successor even before she met her partner," added Yauk who writes the results of his research in the journal Cancer Research.

Yauk and colleagues studied mice that produce sperm cells are continuously exposed to cigarette smoke for either six or 12 weeks, and all mammals continuously produce sperm.

The result, they found that 1.7 times as many mutations occur in the DNA of cells of cigarette smoke-exposed mice compared to mice not exposed to smoke after 12 weeks, and 1.4 times as many mutations after six weeks.

"This suggests that damage is related to the duration of exposure to cigarette smoke, so the longer you smoke the more mutations accumulate and the greater will be the greater the potential impact on your sperm," said Yauk.

In another study also said most of the men who undergo IVF are smokers. Moreover, the study also noted that smokers husband has a lower ability to impregnate their wives than husbands who do not smoke.

Smoking women, Beware of Early Menopause

      Women who smoke are likely to begin menopause before the age of 45 years and also to make them face the risk of osteoporosis and heart disease, Norwegian researchers report.

"Among the 2,123 women aged 59 to 60 years, those who currently smoked were 59% more likely to experience early menopause compared with women who do not smoke," said Dr.. Thea F. Mikkelsen of the University of Oslo and colleagues.

For the heaviest smokers, the risk of early menopause was nearly doubled. However, women who were smokers, but quit at least 10 years before menopause, were substantially less likely to quit than smokers menstruation before age 45 years.

There is evidence that smoking later in life makes a woman more likely to experience early menopause, while smokers who quit before middle age may not be affected, Mikkelsen and her team in the online journal BMC Public Health.

They investigated the relationship further and determined if exposure to second-hand smoke may also affect the timing of menopause. The researchers found that nearly 10% of women entering menopause before the age of 45 years.

A total of 25% were current smokers, 28.7% were ex-smokers and 35.2% reported current passive smokers. Current smokers were 59% more likely to have reached menopause before age 45, while early menopause almost two times more common among women who smoked the most.

But women who had quit smoking at least a decade

before menopause were 87% more likely than their peers who currently smoked and had an early menopause.

Compared with married women, widows were also at increased risk of early menopause, as were women who say their poor health condition. Women with more education are less likely to enter menopause early, but they are also less likely to be smokers.

Involvement in social activities also reduce the risk of early menopause. The researchers found no link between coffee or alcohol consumption or passive smoking with risk of early menopause.

"The earlier a woman stops smoking," said Mikkelsen and his team, "There are protections that he get in connection with the arrival of early menopause."
