Although it is well known that smoking has negative impacts on the general health of people, such as cardiovascular, respiratory and cancer problems, smoking remains one of the most consumed psychoactive substances.
The World Health Organization stipulates that about 1 billion people worldwide are smokers, representing approximately 30% of men and 7% of women.
However, what is the effect it has on fertility?
Many studies have been done addressing this question, and although some show inconclusive results, most converge on the same point: smoking is bad, but why and what does it do?
It is thought, on the one hand, that the negative effect of smoking is due to the increased presence of reactive oxygen species, which have devastating effects on cells, damaging their morphology, metabolism and ultimately their vitality.
On the other hand, of the 4,000 components recorded in cigarette smoke, some, such as cotinine, which is derived from nicotine, cadmium and polyaromatic hydrocarbons, have been found in the follicular fluid or seminal plasma of active smokers. This information suggests a potential effect on gametes, and therefore on embryos or even the offspring of these people.
Specifically, it has been concluded that, for women who smoke, the pregnancy rate decreases, miscarriages increase, and the ovarian reserve is altered. For men, the quality of the seminal fluid and sperm is compromised, clearly affecting the viability, motility, and morphology of the cells.
This makes it crucial that both men and women consider these problems and evaluate their habits if they wish to form a family in the future. Contact our specialists for more information. Remember, here at Citmer we want to be part of your history.
