Introduction: Tobacco dependence is considered to be a serious psycho-social problem. Chronic smoking can cause fertility disorders with both sexes. The literature brings up contradictory results in relation to the effects of the smoking on the steroid hormones levels. Only a few papers discuss the effect of the nicotine addiction treatment.Methods: We observed 26 smokers who decided to quit smoking and abstained from smoking for one year. With everyone ...

Introduction: The dependence on tobacco, diagnosis F 17, is an independent condition in the International classification of diseases and presents one of the most widespread addictions. Chronic smoking can cause impairment of fertility in both sexes. However, only a small number of studies were dedicated to the influence of smoking on levels of steroid hormones and their neuroactive metabolites. Neuroactive steroids modulate the effects of tobacco on central nervous system, and...

Objective: Chronic smoking alters the circulating levels of sex hormones and possibly also the neuroactive steroids, however, the data available is limited.Patients and methods: Therefore, a broad spectrum of free and conjugated steroids and related substances was quantified by GC–MS and RIA in premenopausal smokers and in age-matched (38.9±7.3 years of age) non-smokers in the follicular (FP) and luteal phases (LP) of menstrual cycle (10 non-sm...

Background: Smoking represents the most widespread substance dependence in the world. Several studies show the nicotine’s ability to alter women hormonal homeostasis. Women smokers have higher testosterone and lower estradiol levels throughout life compared to women non-smokers. This negatively affects women reproductive function. Furthermore, alteration of neuroactive and neuroprotective steroids occurs in women smokers, which plays an important role in the activity of t...

Introduction: Cigarette smoking is one of the most serious substance abuse problems. It is generally accepted that nicotine and other chemicals in tobacco smoke alter endocrine function in women, induce changes in female hormonal balance and likely contributes to reported associations of smoking with adverse reproductive outcomes, including menstrual dysfunction, infertility, and earlier menopause. Studies on the effects of smoking and smoking cessation on female sex hormones ...

Background: A high percentage of adult smokers try to quit, but most of these attempts fail. The ability to predict the success or failure of smoking cessation efforts will be useful for clinical practice. Stress response is regulated by two primary neuroendocrine systems. Salivary cortisol has been used as a marker for the hypothalamus-pituitary-adrenocortical axis and salivary α-amylase as a marker for the sympathetic adrenomedullary system.Method...
