Hyperspermia is a condition that occurs when men ejaculate an excessive volume of semen during ejaculation. One study suggests that ejaculations that expel more than 6.3 mL of fluid qualify as hyperspermia. According to the World Health Organization (WHO), the lower limit is 1.5 mL. The average volume is about 3.7 mL.
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 the ejaculate, or semen. When produced in healthy quantities, ejaculate plays an essential role in conception.
Ejaculate is made of fluid from several regions: the seminal glands, the prostate, and Cowper's gland. While sperm is made in the testes, it does not join the fluid known as ejaculate until shortly before ejaculation.
Ejaculate is responsible for facilitating the sperm's movement, nourishment, and navigation through the female reproductive organs (cervix, uterus and fallopian tubes) in search of the egg. Without ejaculate, sperm would be unable to survive the process.
The cause of hyperspermia is not known, but it may be related to long periods of abstinence between ejaculations, causing a build-up of fluids. In this case, the ejaculate may be excessively diluted or may contain an increased number of dead or dysfunctional sperm, due to the time period between ejaculations. This may make conception more difficult, as fewer sperm per milliliter of ejaculate are available to fertilize an egg.
