Hyperspermia

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 7 mL.[2] It is the opposite of hypospermia, which is defined as a semen volume of less than 1.5 mL.

-spermia,
Further information: Testicular infertility factors
Aspermia—lack of semen; anejaculation
Asthenozoospermia—sperm motility below lower reference limit
Azoospermia—absence of sperm in the ejaculate
Hyperspermia—semen volume above upper reference limit
Hypospermia—semen volume below lower reference limit
Oligospermia—total sperm count below lower reference limit
Necrospermia—absence of living sperm in the ejaculate
Teratospermia—fraction of normally formed sperm below lower reference limit

Hyperspermia alone does not appear to influence sperm health. However, large volumes of ejaculate may have lower relative volumes of sperm, leading to low fertility.[3][1]

In some cases, high semen volumes can be a symptom of male accessory gland infection.[4]
