Smoking, bad for your fertility and your child’s – health – 09 September 2010 – New Scientist

September 11

Yet another reason to give up smoking. Smoking may harm not just your fertility but that of the next generation.

Two separate studies show that men who smoke have a lower concentration of proteins in the testes that are essential for producing sperm, while women who smoke during pregnancy may be sowing the seeds of infertility in their unborn child.

In one of the studies researchers obtained 24 testes, from 37 to 68 day embryos after legally terminated pregnancies. They found that the number of germ cells – responsible for forming eggs and sperm – was reduced by 55 per cent in fetuses from women who’d been smoking while pregnant. They also found a 37 per cent reduction in the ordinary or somatic cells in the embryos.
