Of this, around 1% by volume is sperm cells. The U.S.-based National Institutes of Health defines hypospermia as a semen volume lower than 2 mL on at least two semen analyses. [2] The presence of high levels of fructose (a sugar) is normal in the semen and originates almost entirely from the seminal vesicles.
Sperm count, or sperm concentration to avoid confusion with total sperm count, measures the concentration of sperm in ejaculate, distinguished from total sperm count, which is the sperm count multiplied with volume. Over 16 million sperm per milliliter is considered normal, according to the WHO in 2021. [8] Older definitions state 20 million.
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 ...
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml). This is the most common type of fertility testing.

It is the opposite of hypospermia, which is defined as a semen volume of less than 1.5 mL. Hyperspermia alone does not appear to influence sperm health. However, large volumes of ejaculate may have lower concentrations of sperm, leading to low fertility. [3] [1] In some cases, high semen volumes can be a symptom of male accessory gland ...
“This low circulating blood volume causes the release of the hormone vasopressin and when in high enough concentrations, vasopressin constricts blood vessels and causes higher blood pressure ...
People with high blood pressure who slept for shorter durations were more likely to show poor cognitive function and increased levels of markers of brain aging and injury, a new study has found.
