Sexuality2What is human sexuality? Human sexuality refers to how men and women experience and express themselves as sexual beings. This includes the sexual attitudes, feelings, and behaviors of human beings (King, 2012). The development of human sexuality is influenced by several aspects which include biological, gender identity, gender roles, and sexual orientation. A biological aspect of human sexuality includes the reproductive system. The reproductive system is developed and maintained by hormones that influence our sexual behavior. The endocrine system is a network of ductless glands that secrete hormones into the bloodstream (King, 2012). The testicles of a male and the ovaries of a female are part of the endocrine system.The testicles of a male along with the adrenal glands manufacture and release androgens which are the masculinizing hormones. The androgens that are naturally occurring include testosterone, androstenedione, and dehydroepiandrosterone. A man’s bloodstream usually has a larger amount of these hormones compared to a woman (Regan, 1999).The ovaries of a female manufacture and release two primary hormones. These hormonesinclude estrogen and progesterone. The ovaries also produce small amounts of testosterone. The adrenal glands are also responsible for manufacturing testosterone in a female (King, 2012).The role of testosterone is a vital component of human sexuality. Men with high levels of testosterone seem to have a higher sexual desire compared to women. A low level of testosterone in both and women decreases the urge of sexual activities. The use of hormone replacement therapy with testosterone has been shown to increase sexual desire in both men and women (King, 2012).
