My boyfriend’s watery sperm

My boyfriend’s sperm is very watery. Kindly tell me the drug he can use to make it thick.

It is difficult to use naked eye observation to confirm the thickness of a person’s sperm since the consistency of semen usually changes some minutes after ejaculation. Therefore, the best way to confirm the nature of a semen is through a laboratory examination. I will therefore advise that before you confirm whether or not your boyfriend’s sperm is watery, let him take a sample to the laboratory for examination.
