Abstract

One of the consequences of sexual behavior is reproduction. Thus, this behavior is essential for the survival of the species. However, the individual engaged in sexual behavior is rarely aware of its reproductive consequences. In fact, the human is probably the only species in which sexual acts may be performed with the explicit purpose of reproduction. Most human sexual activities as well as sex in other animals is performed with the aim of obtaining a state of positive affect. This makes sexual behavior important for wellbeing as well as for reproduction. It is not surprising, then, that sexual health has become an increasingly important issue, and that knowledge of the basic mechanisms controlling that behavior are urgently needed. The endocrine control of sexual behavior has been extensively studied, and although it is established that gonadal hormones are necessary, some controversy still exists concerning which hormone does what in which species. The brain areas necessary for sexual behavior have been determined in almost all vertebrates except the human. The medial preoptic area is crucial in males of all non-human vertebrates, whereas the ventromedial nucleus of the hypothalamus is important in females. Modulatory functions have been ascribed to several other brain areas.
