What TCM would you recommend to increase sperm count ? My husband is a smoker and I am worried that his sperm count is low because of his bad habit...

Quitting smoking will definitely be beneficial for his general health. If you are considering TCM to help strengthen you and your husband's bodies to increase your chances of conceiving, it is best to go down to a doctor you can trust for a consultation. Only then, can a doctor advice you on which areas within the body needs strengthen and what kind of treatment and lifestyle changes need to be put in place.
