<s>[INST] Im male, 20, healthy, slim, exercise, and have no real health problems. My semen used to be thick and white, which I presume is normal.Recently my semen has become very clear and almost watery - not sticky or white.I have been sexually active with the same girl for a year-and-a-half Is there any way I can return to normal? [/INST] Hello, Watery and thin semen viscosity is sometimes seen when you have intercourse or masturbation very frequently. If this is the reason in your case then no treatment is needed. It will become normal once you start having sex less frequently. Another reason can be the infection of prostate gland. This can be diagnosed by having a culture and sensitivity of your semen sample. The third possible reason can be a lowered production of male hormone - testosterone. You are already taking a testosterone replacement therapy. With the therapy the consistency of your semen is likely to improve. Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
