###Human: Why does my ejaculate get stuck and not come out during orgasm? ###Assistant: Hi. I have gone through your query, I would like to know a few more details about your symptoms. How is your urinary flow, do you have to strain? Have you had any endoscopic procedure or catheterization done in your urethra? Are you only on Dutasteride or do you take alpha-blockers as well? Why were you prescribed Dutasteride at 35 years of age? The process of ejaculation requires a coordinated connection on the muscles surrounding the root of the urethra to expel the semen. Also, the quality of the erection needs to be evaluated in the clinic, because a fully rigid erection is required for a forceful expulsion of semen. I cannot be certain, but it appears that there is an issue in the same in your case. There is no specific name for the condition though.  Also, 35 is a very early age for you to have prostatic enlargement large enough to be on Dutasteride. Though ejaculation problems are not attributed to it, it may be worthwhile to withhold the drug for a few weeks. If it is still persistent, then further testing can be performed.
