Sperm Color
An_248470 posted:

I have noticed that my sperm color has always been slightly yellow.
I'm wondering if there's any problems with that, and what are the causes.

Thanks so much for the help.

Unless you are looking with a microscope, it's not your sperm you are seeing, but rather the combination of sperm (less than 1%) and semen (99%). The semen is produced by the prostate gland, and its color, smell, taste, consistency are determined by your diet, age, frequency of ejaculation, etc. There could be cause for concern, as the normal color is milky-white. See the following website at the Mayo Clinic:

Doctor Todd B. Nippoldt, M.D. answers the question with this information:
Semen color and consistency can vary based on several factors, such as age, diet and frequency of ejaculation. However, yellowish-green semen may indicate a prostate infection. Semen is normally a whitish, cloudy fluid. It's usually quite thick just after ejaculation, but liquefies about 20 to 30 minutes later.
Changes in the appearance of semen are usually temporary and not a health concern. However, sometimes these changes can be a sign of an underlying medical condition that requires further evaluation. If these changes persist for longer than a week or two or if the color change is associated with other symptoms such as pain, fever, sexual dysfunction or blood in the urine, see your doctor for an evaluation.
