Hello thanks for asking from HCM for your health related queries First of all I would like to tell you that this is not a scam. You have to pay for detailed personalised response but for public forum questions you have to pay nothing. So please don t worry about the service. Now coming to your query. Chantix is Venenicline and the drug is commonly used in tobacco smoking cessation programs to reduce the craving of tobacco and to prevent withdrawal symptoms. It is a nicotine receptor agonist drug and is similar to nicotine in actions. The drug is associated with nausea, insomnia, weird dreams, abdominal cramps etc side effects. It is not associated with any serious significant effects on sperms. So I dont think there is any need of worry while of this drugs as far as fertility is concerned. Hope this helps you. Thanks and Take care.
