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 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.
Terms oligospermia, oligozoospermia, and low sperm count refer to semen with a low concentration of sperm [1] and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically oligoasthenoteratozoospermia ).
The woman is over 35 years old. [80] The woman has a history of endometriosis. [81] The woman has infrequent or irregular menses. There is a male factor involved. A doctor or WHNP takes a medical history and gives a physical examination.
A man can have a total number of sperm far over the limit of >16 million sperm cells per milliliter, but still have bad quality because too few of them are motile. However, if the sperm count is very high, then a low motility (for example, less than 60%) might not matter, because the fraction might still be more than 8 million per millilitre.
Collecting the sperm at home gives a higher sperm concentration, sperm count and motility, particularly if the sperm is collected via sexual intercourse. [36] If the semen sample is to be collected by masturbation, a specimen from the early stages of the ejaculate should be into a clean, unused, sealed collection cup.
Various environmental and lifestyle factors have been proposed to explain the decline in semen quality observed over the last 50 years. Mobile phone use may affect semen quality, study suggests ...
Sperm motility describes the ability of sperm to move properly through the female reproductive tract (internal fertilization) or through water (external fertilization) to reach the egg. Sperm motility can also be thought of as the quality , which is a factor in successful conception ; sperm that do not "swim" properly will not reach the egg in ...
