Hi. After masturbation the semen is not white; sometimes yellow, sometimes it comes as a dark yellow. What is the reason for this?
Semen is normally off-white. It might get tinted yellow from urine, either leftover in the urethra or that escapes from the bladder during the excitement of ejaculating. A dark yellow, gold, or even green color indicates a possible infection in your prostate. It would be advisable to see a doctor concerning this.
Thank you. I'll ask one more thing: Can this cause problems in the future? You said that in the excitement ejaculating some urine escapes. Is a problem?
No. It is considered normal.
