Appearance

Milk white
Clear, white, or slightly gray semen is usually considered healthy.
Yellow
A blockage can keep urine from completely leaving your urethra — the tube that drains urine out of your bladder — when you pee. This is known as urinary retention. Semen passing through the urethra can get mixed together with trapped or leftover urine, giving your semen a yellowish tint. This is most common if you ejaculate shortly after you pee. Some causes may require medical attention, including: urinary tract infection (UTI) / benign prostatic hyperplasia (enlarged prostate) / bladder obstruction. Yellow semen can also be caused by a prostate infection. This can happen when bacteria from your urinary tract gets into your prostate gland.
Black
Injuries to your spinal cord may result in dark brown- or black-colored semen. High levels of heavy metals — such as lead, manganese, and nickel — in the blood may cause dark-colored semen. This may result from exposure to contaminated food, water, or other environmental factors. Consult a healthcare professional if you think you’ve been exposed.

Semen is typically whitish-gray with a jelly-like texture, but it can fluctuate with different lifestyle changes. Unless you’re experiencing other symptoms, temporary changes in the color of your semen usually aren’t a cause for concern.

If your semen is a different color than usual, take a few moments to scan your body for other changes.

Semen that’s tinged with yellow, green, pink, red, orange, or brown isn’t ideal, but it may not be cause for concern unless it’s accompanied by other unusual symptoms.

Genital soreness, itching, or burning could point to an underlying infection or other condition. When it comes to consistency, semen that’s thicker than usual could be a sign of dehydration.

Your semen may show slight color changes throughout your life, even when you’re in good health.

If your semen changes significantly in color, consistency, amount, or smell, consult a healthcare professional. Likewise, if your ejaculate is accompanied by an itch or pelvic pain, it’s time to consult a clinician.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
