In the case of reproduction, virtually all studies support the fact that smoking has a negative impact on the reproductive future. When women smokers are compared to non-smokers, the infertility rate and the time to conception is longer in women who smoke than in non-smokers. Smoking appears to accelerate the loss of eggs and reproductive function and may accelerate the time to menopause by several years.
In relation to men, those who smoke have a lower sperm count, lower motility and fewer normal forms in seminograms. However, the effects of smoking on male fertility have not been conclusive.
Therefore, in cases in which Artificial Insemination treatments are indicated, if we have a semen sample with decreased concentration, motility and morphology, this treatment could not be indicated. In the case of women who smoke, as the quality and quantity of eggs decreases, pregnancy rates in this type of treatment will also be compromised.
