I am a 27-year-old male, and I feel a burning sensation during urination and need to urinate frequently sometimes. I feel difficulty in starting to urinate sometimes. After examination and many tests, the doctor advised me to take the tablet Urimax 4.0 for three months, and I have been taking it for the last 25 days. During this period, I also feel difficulty in ejaculation, and my semen does not come out from my penis. I also have difficulty with erections and feel less interested in sex. Is it prostate cancer? I am worried and cannot focus on my studies. Is ejaculation and erection problem due to side effects of the medicine, or is it something serious? Kindly help.
