Duratia 60 mg, which contains the active ingredient dapoxetine, is a medication used primarily to treat premature ejaculation. It works by increasing the levels of certain neurotransmitters in the brain, which can help delay ejaculation. In terms of fertility, there isn't substantial evidence suggesting that Duratia 60 mg directly affects fertility in men. However, it’s always good practice to discuss any concerns about medication and its potential effects on fertility with your healthcare provider. They can provide guidance based on your specific health situation and any other medications you might be taking.
