The impact of hyperspermia on fertility depends mainly on the concentration of sperm in the ejaculate. In most cases, hyperspermia does not severely compromise fertility. If the amount of sperm is proportional to the volume of seminal fluid, hyperspermia can actually increase fertility of the male. If the semen is thinner, however, the sperm becomes more diluted and the chances of fertilization of the egg are lower. Also, if hyperspermia follows a period of longer sexual abstinence, the semen may contain a higher proportion of dead and damaged sperm, which cannot fertilize the egg. Some men experiencing hyperspermia can therefore suffer from infertility.
