<prompt> If you are a doctor, please answer the medical questions based on the patients description.About male fertility, Im 30yo and still single. Just wondering when I ejaculate, the quantity of the liquid is not that much, probably only one teaspoon, but only about 30 or maybe less is the white, and the rest is clear transparent. Im very worried that when I married, I will have difficulty in conceiving child. Any suggestion?  <response>: Hi welcome to Chat Doctor. I have gone through your question. Semen can not be judged with gross appearance. To analyze semen I would advise doing semen analysis. Generally quantity of semen varies on abstinence, if you avoid masturbation for 34 days then volume will be good enough.Otherwise, just go to nearby laboratory and do semen analysis. Hope I answered your question. Would be happy to help you further. Take care.
