| No. Some chemicals, like the ones in alcohol, cigarettes, cocaine, heroin, and marijuana, can affect sperm badly. They may reduce the sperm count, or the quality of the semen, which may make it difficult for a man using them to cause a pregnancy. (It would be a very bad idea, however, to rely on taking these drugs for birth control.) But this will not affect the general health of the women a man has sex with.
On the other hand, certain chemicals and nutrients that a man ingests may alter the taste of his ejaculate. For example the sugars and vitamins in fruit and naturally processed alcohol may make semen taste sweet. Coffee and chemically processed alcohol may make it taste bitter. But neither of these effects will affect a woman's health.
