I have gone for iui treatment for pregnancy with a gynecologist. when I am asked to provide sample of my semen it does not come out even after lot of efforts.in semen analysis test my motility is 30 percent. Gynae has prescribed me with medicines like Lineator .How can my semen come out easily so that I can provide it at time of test.i had wrong childhood habits of masturbation.my penis does not remain erect for long time so as to penetrate. I want to improve quantity and quality of my semen so as to get success in making my wife pregnant.
