I'm unaware of any physiological mechanism by which Yohimbine could help this other than reduction of bodyfat. But it you really have gotten to 8% (how did you determine this?) and it is still there, I don't see how it would help you. If there's no glandular enlargement, the option is to just get leaner. Yohimbine can help wit this, but I don't believe it will help spot reduce in that area. If they are wrong and it is glandular, there are surgical options and perhaps hormone management (but that should be approached very judiciously).
