Definition - What does Hyperspermia mean?
Hyperspermia is a condition that occurs when men expel abnormally large volumes of ejaculate fluid during ejaculation. The average amount of semen ejected per ejaculation is 2-6 mL. Ejaculations that expel more than 6.3 mL of fluid qualify as hyperspermia.
While a limited amount of scientific research exists on the topic, it has been theorized that this condition may create issues with low sperm count or low sperm quality.
FertilitySmarts explains Hyperspermia
In order to leave the male body and enter the female reproductive system, sperm is accompanied by a variety of fluids, all of which make up ejaculate, or semen.When produced in healthy quantities, ejaculate plays an essential role in conception. While sperm is made in the testes, they do not join the fluid known as ejaculate until shortly before ejaculation.
Ejaculate is comprised of fluid from several regions: the seminal glands, the prostate, and Cowper's gland. However, 80% is provided by the seminal glands. Ejaculate is responsible for facilitating the sperm's movement, nourishment, and navigation through the female cervix in search of the egg. Without ejaculate, sperm would be unable to survive the process.
Hypospermia may be caused by long periods of abstinence between ejaculations, causing a build-up of fluids. In this case, the ejaculate may contain an abnormally large number of dead or dysfunctional sperm, as it possible they expired in the body between ejaculations. This may complicate conception, as unhealthy or dead sperm are unable to fertilize an egg.
It is likely that seminal volume ejaculated during intercourse is higher than during masturbation.
