Ovotoxicity of smoking and impact on AMH levels: a pilot study.

Abstract

Our study aims to analyze the correlation between the decrease of ovarian reserve and lower oocyte quality produced by the follicle associated with use of tobacco. In particular, the study analyzed the potential effects of cigarette smoking on hormonal dosages in infertile patients and patients with recurrent miscarriages. This retrospective study included 61 women with a history of infertility and recurrent miscarriage between March 2016 and March 2019 selected at the clinic of poly-abortivity and infertility at the ASL Roma 2 - Department of Obstetrics and Gynecology, “S. Eugenio” Hospital. Patients’ medical history (familiar, physiological and pathological with particular attention to smoking habits and nutrition), the obstetric history, gynecological examination and ultrasound were recorded. The serum concentration of FSH, AMH, Inhibin B were examined between the second and third day of the period. A total of 61 patients between 25 and 43 years of age admitted into our clinic were identified; 42 patients with a history of recurrent abortion (more than two abortions) and 19 patients with a history of infertility were selected. A total of 31 non-smokers women (50.82%) (G1) and 30 (49.18%) (G2) smokers were included. No differences were detected between the two groups under examination; the parameter that did appear discordant is the AMH value; this value scored higher in non-smokers than in smokers. Specifically, in smoker patients with recurrent abortions. The connection between nicotine, combustion material, and oocyte quality is an important and controversial research topic. Further studies are needed to clarify the influence of nicotine and combustion on the ovarian reserve in order to identify the main risk factors.
