I have been on oral duta for soon 8 months, I have reduced ejaculation force, which means my sperm no longer shoots out just mostly oozes out. It can shoot out but only if im lucky. But If I wait a few days without ejaculating my sperm shoots out twice and the rest just oozes out. This side effect sucks but it's not too problematic for me to quit oral. Also my sleep is affected so I sleep worse but still not bad enough for me to quit the pill. These two problems is my only side effects. Otherwise my libido and boners are great and I think dutasteride has made me even stronger. I got a reply from a guy yesterday he told me he use 0.5mg EOD dutasteride orally for 4 years he has no such side effects that I have. He don't have any side effects at all. We all respond differently to drugs. The only way to know is to try it my friend.
