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.
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]
Hypospermia is a condition in which a man has an unusually low ejaculate (or semen) volume, less than 1.5 mL.It is the opposite of hyperspermia, which is a semen volume of more than 5.5 mL. [1]
The ejaculate is expelled in spurts, due to the movement of the muscles propelling it. These muscle contractions are related to the sensations of orgasm for the male. [5] Sperm are produced in the testes and enter the ejaculatory ducts via the vas deferens. As they pass by the seminal vesicles, a fluid rich in fructose combines with the sperm.
Sperm cells are carried out of the male body in a fluid known as semen. Human sperm cells can survive within the female reproductive tract for more than 5 days post coitus. [15] Semen is produced in the seminal vesicles, prostate gland and urethral glands.

Usually, men will be able to observe a runny/fluid, low-volume semen by themselves during masturbation. Since the seminal vesicles contain a viscous, alkaline fluid rich in fructose, a chemical analysis of the semen of affected men will result in a low concentration of fructose and a low pH. A microscopic semen analysis will reveal aspermia ...
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 .
