###Human: Semen and urine are yellow colored. Is it fine? ###Assistant: Hi. Yellow urine is usually due to less water intake, sweating, vitamin pills or certain foods or food color. Yellow semen is seen when you masturbate or have intercourse after a break of a few days. In both cases, there is no cause to worry if there are no other symptoms. This has no relation to masturbation. If you have persistently yellow urine or yellow eyes, contact your doctor. Take care.
