<s>[INST] Hi, lately I've noticed that my urine is very, very dark, and my discharge of seamen is unregularily thick. Also, when I wake in the mornings, I'm very queezy n have been vomiting. And I've also noticed that the whited of my eyes have a yellow cast to them. This has all happened within the last three weeks. I am 36, 180 pounds with no past medical history. [/INST] Hello, SirWelcome to healthcaremagic.I can certainly understand your concern.I have worked through your query in detail.As per your symptoms the possibility of significant urinary tract infection is very high.This can cause significant change in seminal parameters causing thick or foul smelling semen with or without urinary disturbances.It's important to get few tests to determine further course of action-urine examination, scrotal ultrasound Doppler to look for any infection of the testicles or epidydimis.A short course of antibacterial antibiotics will help to clear the infection and improve the seminal parameters.Repeat testing after 2 weeks will help to assess the outcome.Please check with your physician if he shares my view and if can prescribe these medications to you.Post your further queries if any.Thank you </s>
