hi sir,hair loss though appears as a minor problem,only the sufferers know its magnitude and the resultant distress.bio HGF forte is a combination of biotin,iron,l-cysteine,methionine(both are amino acids),calcium pantothenate.what i would like to impress upon you is all the above ingredients are essential for hair growth and also for various metabolisms in our body.so none of the above can cause decrease in sperm count as you heard.just relax and happily go on with bio HGF.i assure you that it doesnt cause any decrease in sperm count.go ahead.let me also throw some light on permanent cure for hair loss i.e;HAIR TRANSPLANTATION.of course only if all the other measures fail and hair loss is intense causing baldness then you can go for it.many of my patients and even junior colleagues got benefitted through hair transplant.first take bio HGF for atleast 3-5 months and then you can think of next step.hope my answer has cleared your doubt.other queries if any,please let me know.its my pleasure to be of any help to you.thank you.take care.i pray god to make your treatment a big success.bye.
