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 ...
The seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen. [5] The prostatic secretion, influenced by dihydrotestosterone, is a whitish (sometimes clear), thin fluid containing proteolytic enzymes, citric acid, acid phosphatase and lipids. [ 5 ]
Penile discharge is fluid that comes from the urethra at the end of the penis that is not urine, pre-ejaculate or semen. [2] [3] Common causes include infections due to gonorrhea, chlamydia, or trichomoniasis. [3] In gonorrhea the discharge may be white, yellow, or green. [4] [5] A swab of the discharge is usually performed. [5] Treatment ...
Laboratory examination of seminal vesicle fluid requires a semen sample, e.g. for semen culture or semen analysis. Fructose levels provide a measure of seminal vesicle function and, if absent, bilateral agenesis or obstruction is suspected. [13] Imaging of the vesicles is provided by medical imaging; either by transrectal ultrasound, CT or MRI ...
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.
Bulbourethral glands are located posterior and lateral to the membranous portion of the urethra at the base of the penis, between the two layers of the fascia of the urogenital diaphragm, in the deep perineal pouch.
Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and sclera due to high bilirubin levels. [3] [6] Jaundice in adults is typically a sign indicating the presence of underlying diseases involving abnormal heme metabolism, liver dysfunction, or biliary-tract obstruction. [7]
The discharge also changes in color and consistency during this time, becoming clear with an elastic consistency. [12] After ovulation the body's progesterone levels increase, which causes a decrease in the amount of vaginal discharge. [12] The consistency of the discharge once again becomes thick and sticky and opaque in color. [12]
