  Sexual Biology
Instead of being responses to a message sent by the brain along the nerve pathways, these changes and many others are responses to messages delivered in a kind of code by chemicals known as hormones.
They are responsible for the bursts of energy produced during emergencies for rapid growth infancy, a slower rate of growth during childhood and the final explosion of growth during adolescence.
Hormones are produced and released in response to instructions from the brain, by various organs and tissues but the chief producers are the endocrine glands.

Understanding the processes and underlying mechanisms of sexual arousal and orgasm is important to help people become more familiar with their bodies and their sexual responses and to assist in the diagnosis and treatment of sexual dysfunctions.
The excitement stage of sexual arousal is characterized by increased blood flow to blood vessels (vasocongestion), which causes tissues to swell.

Sexually transmitted diseases should be diagnosed and treated by qualified medical practitioners, and all sexual partners must be treated in order to avoid reinfection.
These dysfunctions may be caused by physical problems such as fatigue or illness; the use of prescription medications, other drugs, or alcohol; or psychological factors, including learned inhibition of sexual response, anxiety, interfering thoughts, spectatoring (observing and judging one's own sexual performance), lack of communication between partners, insufficient or ineffective sexual stimulation, and relationship conflicts.
The most noted scientific studies of sexuality in the 20th century are those of American biologist Alfred Charles Kinsey and his colleagues and those of William H. Masters and Virginia Johnson.

Although the study of animal sexual behavior by neuroendocrinologists has traditionally been concerned with mechanisms of copulatory responding, more recent use of conditioning and preference paradigms, and a focus on environmental circumstances and experience, has revealed behaviors and processes that resemble human sexual responses.
There is no human counterpart to lordosis (at least not as an unambiguous, estrogen-dependent postural display of sexual receptivity in females), and human sexual behavior is so shaped by experience and learning that it seems to defy hormone actions that are critical to the display of animal sexual behavior.

provided a simplified formulation of the neuropharmacology of normal human sexual response: the initial phase is libido, or desire, linked to satisfaction with sex; the second phase is arousal of genital tissues, resulting in erections in men and genital lubrication and swelling in women; and the final phase is orgasm, accompanied by ejaculation in men.
