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.
Presence of blood in semen (hematospermia) leads to a brownish or red coloured ejaculate. Hematospermia is a rare condition. Semen that has a deep yellow colour or is greenish in appearance may be due to medication. Brown semen is mainly a result of infection and inflammation of the prostate gland, urethra, epididymis and seminal vesicles.
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 ...
Thus, a positive result for blood can represent the presence of red blood cells , free hemoglobin (hemoglobinuria), or myoglobin (myoglobinuria). [51] Red blood cells can sometimes be distinguished from free hemoglobin or myoglobin as the former causes a speckled pattern on the test pad while the latter results in a uniform color change.
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]
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 .
Wright's stain is a hematologic stain that facilitates the differentiation of blood cell types. It is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears, urine samples, and bone marrow aspirates, which are examined under a light microscope.
