Patient discussion about fecundity

Q. What is the connection between alcoholism & male fertility? If a guy drank heavily for many years, then stayed sober for many years, would his ability to impregnate a woman disappear, or be at all diminished, as a result of his years as a hard-core alcoholic? In other words, would he not have to worry about using any birth control because in his situation it was rendered unnecessary due to the negative effects of long-term drinking? And would such bad effects, if indeed they had kicked in, have been canceled out by a long period of sobriety after the drinking years?

A. i"ve been sober for six years now,drank heavily for 12 years,i now have three kids,so in other words wrap that rascal,lol

Q. Can cystic fibrosis patients have children? My boyfriend has cystic fibrosis, and currently he’s treated with many medications but usually healthy (other than pneumonia from hospitalization from time to time). I heard that men with cystic fibrosis can’t have children - is that true? Is there anything he can do about it?


Q. Do women with cystic fibrosis have difficult pregnancy? My wife has cystic fibrosis, and after 3 year of marriage we decided we want a baby. I know that men with cystic fibrosis are usually infertile and can’t have children- is that the case also for women with cystic fibrosis? Is the pregnancy in women with cystic fibrosis more problematic? Is it dangerous?

A. Before you attempt a pregnancy, you should consult her doctor to make sure she can tolerate it, because very severe disease can make the pregnancy dangerous for her. If her disease isn’t so severe, usually there are no special problems.
