Goodbye Y: Men Who Smoke Have Missing Male Chromosomes
Printable View
Interesting, thanks for sharing! This was in blood cells specifically, but since sperm cells are constantly dividing it stands to reason tthat this could be one huge reason why smoking sways pink.
This totally fits in what I see with the Custom Plans where the majority of couples wanting boys have the DH smoking (and the vast majority of those who got opposites, did), whereas only a few couple who want girls have ever had DH smoking.
Do you think it's the actual smoke or nicotine?
Just curious since my husband chews nicotine gum constantly!
We have 3 girls. My husband hasn't touched a cig or tobacco in his life.
I think it's probably the nicotine, tar, other toxins in tobacco/cigs, and the carcinogens generated by burning (smoke etc). Nicotine itself is quite toxic so I'm sure that plays a significant role in decreasing fertility, but I think full-on smoking is definitely worse/sways more. But since it's so damn unhealthy to smoke, I think chewing nicotine gum is an excellent compromise of health/safety and pink swaying. If my pink sway fails, I will consider adding nicotine gum to my next sway as long as I'm not BFing. I would never, ever consider smoking but short term nicotine gum use isn't a huge deal at all IMO.Quote:

He has had 6 sons though and is 42 but his doctor did an all over health check not so long ago and said he looks like a 25 year old! (meaning his health stats not looks). He started smoking late compared to most though (22-23) so perhaps it had not had enough time to effect him or maybe he is just super lucky and healthy. But he could be healthier, and he has lots of kids he needs to stick around for.
I have three girls and my dh smoked for most of the time that we conceived our dd's. He quit about 5 is years ago. My father was a pack or more a day and had 4 boys and 4 girls. My sister in laws husband doesn't smoke and has 4 girls. But I agree it could have some effect with their fertility.
I have never said that smoking is the only way to get a girl, giz. In fact that would be impossible because people got girls before they started smoking a few hundred years ago.Quote:
