The risk of infertility is higher in smokers than in non-smokers. While smoking reduces the quality of the ovaries in women, it also negatively affects egg production and reproductive performance. Nicotine ingested with smoking disrupts the egg cells and may cause menopause to come earlier than expected. While smoking and alcohol use make it difficult to conceive naturally, they also accelerate miscarriages.
Smoking also negatively affects male reproductive health. Men who smoke heavily, such as 1 or 2 packs a day, have more shape and movement disorders and anomalies in their sperm. Alcohol also has a very significant negative effect on sperm production.
Smoking addicted men and women are also at risk for in vitro fertilization
Studies have shown that the chance of conceiving with in vitro fertilization method is at least 2 times lower for cigarette-addicted women than non-smokers. It has been determined that smoking has negative effects on egg development, ovulation, fertilization and early development of the embryo in IVF treatment.
It has been reported that in IVF treatment, when the same number of embryos are transferred in smokers compared to non-smokers, the pregnancy rate decreases and approximately more applications are required for pregnancy. At the same time, the response to the treatment of stimulation of egg development may be worse.
When in vitro fertilization (ICSI) is performed with the sperm of cigarette-addicted men, the chance of pregnancy decreases significantly compared to non-smokers. Even quitting smoking 6 months before infertility treatment has a very positive effect on the result of the treatment.
