Blush: Ejaculate colours

Hello readers!

To continue the colour theme from two weeks ago, I decided to write about the colours of ejaculate!

The usual colour of semen is white-grey.

Its consistency can vary, but as long as it isn’t extremely sticky and viscous (a sign of possible inflammation), it’s completely normal. Some viscosity is perfectly fine!

If the semen is slightly brown, pink, or red, there is a possibility of blood in the semen. This could be because of inflammation or bleeding in the interior organs (prostate or seminal vesicle). This is only a worry if the colour persists for a week or two. Get it checked out at this time at the latest.

A yellow tinge to semen could be because of urine, a high white blood cell count, or jaundice. Again, if the colour continues to show up after a week or two, go and see a doctor.

If semen is yellow-green, this is a sign of a possible prostate infection. Again, something to keep an eye on over the next couple of weeks, and if the unusual colour continues to show up, go get it checked out.

If the above colour changes also happen at the same time as other symptoms, such as fever, pain, blood in urine, and/or sexual dysfunction, go see your doctor as soon as you can. Unusual colour changes (especially accompanied by other symptoms) can indicate a medical condition, and it’s best to catch the more serious ones early.

Blush: Sperm

You may have heard about the Texas bill that will fine men $100 USD for masturbatory emissions.

"All masturbatory emissions would be considered reckless abandonment." - Elle Woods in Legally Blonde.

But what exactly is sperm?

According to Merriam Webster, a sperm is a male* gamete, “a mature [cell …] usually possessing a haploid chromosome set and capable of initiating formation of a new diploid individual by fusion with a gamete of the opposite sex”.

But what people usually consider to be sperm (the entire ejaculate) is false. The ejaculate is semen; sperm only makes up about 2-5% of the fluid emitted. The rest of the semen is made up of energy (a sugar fluid) from the seminal vesicles that makes up ~65-70%, prostate secretions (enzymes, citric acid,, and acid phosphatase) that give semen its white colour make up ~25-30%, and a clear secretion from the bulbourethral glands helps with mobility after ejaculation only makes up less than 1%.

*male is used by the dictionary to identify the difference between a sperm (male) and an egg (female) gametes.
