Hematospermia (also known as haematospermia, hemospermia, or haemospermia) is the presence of blood in the ejaculate. It is most often a benign symptom. [1] Among men age 40 or older, hematospermia is a slight predictor of cancer, typically prostate cancer. [2] No specific cause is found in up to 70% of cases.
Secretor status refers to the presence or absence of water-soluble ABO blood group antigens in a person's bodily fluids, such as saliva, tears, breast milk, urine, and semen. People who secrete these antigens in their bodily fluids are referred to as secretors, while people who do not are termed non-secretors.
Forensic serology is the detection, identification, classification, and study of various bodily fluids such as blood, semen, saliva, and urine, and their relationship to a crime scene. A forensic serologist may also be involved in DNA analysis and bloodstain pattern analysis .

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 ...
A urine specimen may be collected, and is likely to demonstrate blood within the urine. [9] 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]
Because the test pad reaction is dependent on pH, false positive results can occur if the urine is highly alkaline. [60] [62] Conventional test strips are not sensitive enough to reliably detect microalbuminuria, a condition in which urine albumin levels are slightly elevated, [64] although dipsticks specialized for this measurement exist. [62]
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 ...
