A new research study has found and identified a chemical pathway by which a mother’s smoking before and after pregnancy might reduce her daughter’s fertility by as much as two thirds. As we all know, cigarette smoking during pregnancy is a definite no-no, and has been shown in retrospective studies to affect the fertility of a woman’s offspring. But this would be the first study that attempted explanation of the biology behind this effect, according to the Canadian scientists behind the research. The research was performed by a team from the Samuel Lunenfeld Research Institute at Mount Sinai Hospital in Toronto that studied and investigated on the impact of polycyclic aromatic hydrocarbons (PAH), a byproduct of smoking, on mouse fertility.
The study included injections of a low dose mixture of PAH to three groups of female mice. One group received PAH before conception and again when they were providing milk for their pups, while one group received PAH only before conception, and the third group received PAH only during lactation. A fourth control group did not receive PAH but were mated at the same time as others. The total amount of PAH given to each...
