====Brain====
The [[hypothalamus]] is the most important part of the brain for sexual functioning. This is a small area at the base of the brain consisting of several groups of nerve cell bodies that receives input from the limbic system. Studies have shown that within lab animals, the destruction of certain areas of the hypothalamus causes the elimination of sexual behavior.<ref name="ReferenceA" /> The hypothalamus is important because of its relationship to the [[pituitary gland]], which lies beneath it. The pituitary gland secretes hormones that are produced in the hypothalamus and itself. The four important sexual hormones are [[oxytocin]], [[prolactin]], [[follicle-stimulating hormone]], and [[luteinizing hormone]].<ref name="ReferenceA"/>{{page needed|date=February 2016}}

Oxytocin, sometimes referred to as the "[[love]] hormone,"<ref name="Sigelman452" /> is released in both sexes during sexual intercourse when an [[orgasm]] is achieved.<ref name="Hornstein" /> Oxytocin has been suggested as critical to the thoughts and behaviors required to maintain close relationships.<ref name="Sigelman452">{{cite book| last1 = Sigelman |first1=Carol |last2= Rider |first2=Elizabeth | year = 2011 | title =Life-Span Human Development| location = Boston| publisher = [[Cengage Learning]] | page = 452 |isbn = 978-1-111-34273-9| url =https://books.google.com/books?id=8smBuRecmDsC&pg=PT480}}</ref><ref name="Hornstein">{{cite book| last1 = Hornstein |first1=Theresa |last2=Schwerin |first2=Jeri | year = 2012 | title = Biology of Women | location = Boston | publisher = [[Cengage Learning]] | page = 205 | isbn = 978-1-285-40102-7| url =https://books.google.com/books?id=ibgKAAAAQBAJ&pg=PA205}}</ref>{{verification needed|date=February 2016}} The hormone is also released in women when they give birth or are breastfeeding.<ref name="Smith">{{cite book | author = Smith, Linda J. | year = 2010 | title = Impact of Birthing Practices on Breastfeeding | location = Burlington, MA | publisher = [[Jones & Bartlett Learning|Jones & Bartlett]] | page = 158 | isbn = 978-0-7637-6374-9 | url =https://books.google.com/books?id=vUncnT6o4k4C&pg=PA158}}</ref> Both prolactin<!--RIGHT?--> and oxytocin stimulate milk production in women.{{citation needed|date=February 2016}} Follicle-stimulating hormone (FSH) is responsible for ovulation in women, which acts by triggering egg maturity; in men it stimulates sperm production.<ref>{{cite book| last1 = Hyde|first1=Janet|author-link1=Janet Shibley Hyde|last2=DeLamater|first2=John|author-link2=John DeLamater| last3=Byers|first3=Sandra | year = 2013 | title=Understanding Human Sexuality | edition = 5th Canadian | location = Whitby, ON, CAN | publisher = McGraw-Hill Ryerson | isbn=978-0-07-032972-0 | pages=100, 102ff }}</ref> Luteinizing hormone (LH) triggers ovulation, which is the release of a mature egg.<ref name="ReferenceA"/>{{page needed|date=February 2016}}
