In the data report, which was presented at the European Society Human Fertilisation and Embryology Authority, were the results of the survey and monitoring 300 couples in which 38% of pregnant women whose husband smoked, and only 22% – with smokers husband. It is believed that the elimination of tobacco for 4-6 months before attempting to insemination (natural or by VRT) improves the chances of conception to the level of non-smoking spouses. The concept of passive smoking become a part of the medical vocabulary of about 50 years ago, when scientists proved that the simple presence of tobacco smoke in the air causes the violation of people, similar to those observed in any of those directly smokes. Medical School McMaster University (Canada) conducted a study of 225 women stories, held IVF and ICSI. Were divided into three groups: smokers, "passive" smokers, nonsmokers, and nonsmokers who have a partner. It was found that in group 1 took root 12% of the embryos in Group 2 – about 16% in the third – 25%. Since The study was based on the results of infertility treatment is carried out IVF protocols, performance is quite significant. Finally, Japanese researchers claim that smoking reduces the chances of having a boy.
So it is worth ponder a simple question: cigarette or unsuccessful IVF protocol? A Kinneigh (A Kinney), of the Psychiatric Institute of New York State, and the staff analyzed the results of ultrasound and serum samples blood taken from 188 women, aged 22-49 years to assess changes in four markers of ovarian age: the number of antral follicles (AFC), levels of follicle-stimulating hormone, inhibin B, and estradiol. Scientists have discovered that serum levels of follicle-stimulating hormone were increased approximately 23% of female smokers compared to nonsmokers. However, the study smoking was not associated with any number of antral follicles, nor with levels of inhibin B or estradiol. Further studies have suggested that the association of smoking with FSH varies with age. Compared with never kurivshimi patients, smokers had significantly higher levels of follicle-stimulating hormone at the age of 30, 35, 40 and 45 years – 0,3, 1,3, 3,2 and 6,9 mIU / ml, respectively. Association of smoking with the levels of FSH may reflect accelerated oocyte atresia, declining quality of the follicle, or dysregulation of the hypothalamic-pituitary-adrenal axis, say the authors.
