Study links cigarette smoke to reproductive impact

A recent study indicates that cigarette smoke affects the reproductive organs of men and women differently, with potential implications for reproductive health. It was found that exposure to cigarette smoke causes genetic and primary changes in the testes and ovaries of mice; in the testes, there was an increase in structurally altered microtubules, which may impact sperm production, while in the ovaries, genetic changes related to cell division and DNA repair were observed, despite no obvious structural alterations. The study emphasizes that smoking could contribute to fertility disorders and may be linked to early menopause in women. It also calls for further research to better understand the underlying mechanisms.
