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] It should not be confused with oligospermia, which means low sperm count.
In medicine, hyperspermia is a condition in which a male has an abnormally large amount of semen or ejaculate volume [1] and is generally defined when the ejaculate is above 6 mL. [2] 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.
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.
A 2017 review and meta-analysis found sperm counts among Western men (i.e. men in Australia, Europe, New Zealand, and North America) declined 50–60% between 1973 and 2011, with an average decline of 1.4% per year. The meta-analysis found no indication the decline is leveling off.

[1] [2] Lecithins are mixtures of glycerophospholipids including phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, and phosphatidic acid. [3] Lecithin was first isolated in 1845 by the French chemist and pharmacist Théodore Gobley. [4] In 1850, he named the phosphatidylcholine lécithine. [5]
An animal study observed an increase in sperm production using celery leaf extract as a supplement. However, celery extract is much more concentrated than eating a stalk of celery or drinking ...
A 1992 World Health Organization report described normal human semen as having a volume of 2 mL or greater, pH of 7.2 to 8.0, sperm concentration of 20×10 6 spermatozoa/mL or more, sperm count of 40×10 6 spermatozoa per ejaculate or more, and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid ...
