{{-spermia}}

In medicine, hyperspermia is a condition in which a male has an abnormally large amount of semen or ejaculate volume{{cite journal |first1=S. |last1=Cooke |first2=J. P. P. |last2=Tyler |first3=G. L. |last3=Driscoll |title=Andrology: Hyperspermia: the forgotten condition? |journal=Hum. Reprod. |year=1995 |volume=10 |issue=2 |pages=367–368 |doi=10.1093/oxfordjournals.humrep.a135944 |pmid=7769063}} and is generally defined when the ejaculate is above 5.5 mL.Kumar; Padubidri; Daftary (2022). Shaw's Textbook of Gynaecology, 18e. [https://books.google.com/books?id=dM-TEAAAQBAJ&pg=PA210 p. 210]. {{ISBN|9788131266311}} It is the opposite of hypospermia, which is defined as a semen volume of less than 1.5 mL.

Hyperspermia alone does not appear to influence sperm health. However, large volumes of ejaculate may have lower concentrations of sperm, leading to low fertility.{{cite journal|last1=Zhang|first1=Yue-juan|last2=Zhong|first2=Jian|last3=Zhu|first3=Wei-jie|date=2015-12-01|orig-date=2015-07-15|title=Evaluation on sperm parameters of ejaculates with hyperspermia|journal=Journal of Reproduction and Contraception|volume=26|issue=3|pages=131–134|doi=10.7669/j.issn.1001-7844.2015.03.0131|doi-broken-date=14 December 2024 }}

In some cases, high semen volumes can be a symptom of male accessory gland infection.{{cite journal|last1=Noweir|first1=Hosam A.|last2=Modgil|first2=Vaibhav|last3=Pearce|first3=Ian|year=2022|title=Male accessory gland inflammation (MAGI): an evolving entity|journal=Journal of Clinical Urology|volume=15|issue=5|pages=414–423|doi=10.1177/2051415820987687}}
