Put down your cigarette! New research on smoking

Smoky and non-smoky female embryo series show that embryos from smoky females develop slower.

Female embryos participating in a flask study program at the University of Nantes Clinic were periodically screened from fertilization of the egg until the embryo was implanted. Recordings showed that at every stage of developmental development, embryos of non-smoky females were slightly delayed in development.

Put Your Cigarette On Your Baby's Health!

"If you want a baby, quit smoking," researcher Thomas Freour told BBC News.
Smoking reduces the likelihood of a child being born, so couples who participate in a fertility program are usually asked to leave for the time of the family planning. During artificial insemination, ova are removed from the mother under laboratory conditions with the father's human germ cells. The fertilized egg then develops for a few days in a Petri dish, which gives it a special opportunity to observe or even divide and grow.
French experts followed 868 embryonic development, including 139 smokers among embryos. It was found that the embryonic status of non-smoky mothers was 49 hrs after fertilization, whereas that of smoky females was 50 hrs. Similarly, the 58-cell state required 58 hours for non-smoky mothers 'embryos and 62 hours for smoky mothers' embryos. Freour emphasized that the development of embryonic mothers of smoky mothers typically produces two ovaries, which is a significant lag. The cause and potential consequences of the observed phenomenon are not known, but it is strongly recommended that anyone who wants a child give up smoking.
