The red color seen in beeturia is caused by the presence of unmetabolized betalain pigments such as betanin in beetroot passed through the body. [2] [3] The pigments are absorbed in the colon. [2] Betalains are oxidation-sensitive redox indicators that are decolorized by hydrochloric acid, ferric ions, and colonic bacteria preparations. [4]
Blood in the semen can cause a pink or reddish colour, known as hematospermia, and may indicate a medical problem which should be evaluated by a doctor if the symptom persists. [11] After ejaculation, the latter part of the ejaculated semen coagulates immediately, [12] forming globules, [13] while the earlier part of the ejaculate typically ...

Semen normally has a whitish-gray colour. It tends to get a yellowish tint as a man ages. Semen colour is also influenced by the food we eat: foods that are high in sulfur, such as garlic, may result in a man producing yellow semen. [19] Presence of blood in semen (hematospermia) leads to a brownish or red coloured ejaculate. Hematospermia is a ...
Semen displacement is an adaptation of the shape of the penis to draw foreign semen away from the cervix. This means that in the event of a rival male's sperm occupying the reproductive tract of a female, the human penis is able to displace the rival sperm, replacing it with his own. [42] Semen displacement has two main benefits for a male.
A mucous rectal discharge may be blood-streaked. With some conditions, the blood can be homogenously mixed with the mucus, creating a pink goo. An example of this could be the so-called "red currant jelly" stools in intussusception. This appearance refers to the mixture of sloughed mucosa, mucus, and blood. [12]
The semen is stored here until ejaculation occurs. Muscles at the base of the penis contract in order to propel the seminal fluid trapped in the prostatic urethra through the penile urethra and expel it through the urinary meatus. The ejaculate is expelled in spurts, due to the movement of the muscles propelling it.
