I read and understand your concern. I am Chat Doctor answering your concern. Colin cancer can be metastatic to the epididymis and other location of the ejaculatory ducts. This is the reason why you have been ejaculated. I advise you should do the USG of the genital system. This will enable the clear picture of the metastasis and accordingly management can be planned.
