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.
If the person is a secretor, the antibodies will bind to the antigens in their saliva rather than the red blood cells, and will not cause red blood cells to agglutinate. [ 5 ] : 25 Secretor status testing was historically used in forensic science , but this has been made obsolete by advances in DNA testing .

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]
Furthermore, when the semen volume is low, less than 1 ml, a urine specimen should be collected immediately after masturbation to search for sperm in the urine. [13] Two days before the urine sample is collected, one is required to drink an alkalinized water to allow the sperm cells to survive.
The p30/PSA test is an immunochromatographic test that detects the presence of the antigen p30 in semen samples. This test functions similar to a pregnancy test, where if the antigen p30 is present a band will appear at the test site and a control band will appear to confirm if the test is working properly. [ 4 ]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The semen is forced to exit via the urethra, the path of least resistance. When the bladder sphincter does not function properly, retrograde ejaculation may occur. It can also be induced deliberately by a male as a primitive form of male birth control (known as coitus saxonicus ) or as part of certain alternative medicine practices.
