Editing Boxer shorts (section)

== Fertility ==
Some studies have suggested that tight underpants (like [[briefs]]) and high temperature are not optimally conducive for [[sperm]] production. The [[testicles]] are outside the body for cooling because they operate for sperm production at a slightly lower temperature than the rest of the body, and boxer shorts allow the testicles to operate within the required temperature range. The compression of the genitals in briefs, boxer briefs, or [[thong]]s may cause the temperature to rise and sperm production to fall. There is a similar theory regarding [[testicular cancer]] risk.<ref>{{cite journal|title=Diurnal scrotal skin temperature and semen quality|year=1990|journal=Reproductive Toxicology|volume=4|issue = 5|pages=229–232|publisher=Sanger & Friman|doi = 10.1046/j.1365-2605.2000.00245.x|pmid = 11012789|last1 = Hjollund|first1 = Niels Henrik I.|last2 = Bonde|first2 = Jens Peter E.|last3 = Jensen|first3 = Tina Kold|last4 = Olsen|first4 = Jorn|doi-access = free}}</ref> Other sources dispute this theory. A study in the October 1998 ''Journal of Urology'', for example, concluded that underwear type is unlikely to have a significant effect on [[male fertility]].<ref>{{cite web|url=http://www.brucegilbertmd.com/uploads/assets//Journal_Articles/boxersvbriefs.pdf |archive-url=https://web.archive.org/web/20080724172518/http://www.brucegilbertmd.com/uploads/assets//Journal_Articles/boxersvbriefs.pdf |url-status=dead |archive-date=2008-07-24 |title=A critical analysis of the role of underwear type in male subfertility |access-date=2019-06-11}}</ref>
