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...

I think it's better that your husband quits totally or cut down on the number of cigarettes he smokes daily before trying any fertility treatment of sorts. Overall, it will be healthier for him and the quality of his sperm will improve as well. No point potentially spending all that money on treatments when there could possibly still be a hindrance. Also, once he quits smoking, it will be healthier for you and any future children as there will be no more secondhand smoke.
