hormones
adrenalin also known as epinephrine, the fight-or- flight hormone released by the adrenal glands during times of stress, fear, anger, or loud noise. The release of the hormone increases heart rate and boosts the supply of oxygen and glucose throughout the brain and body.
anabolic steroid a class of steroids involved in muscle and bone growth and development.
androgen one of various masculinizing steroid hormones, most notably testosterone, dihydrotestosterone, and DHEA. Androgens help build and maintain bone and muscle and contribute to overall energy levels, skin elasticity, sex drive, and cardiovascular health.
androgen dominance a too-high ratio of andro- gens to estrogen or progesterone, which causes acne, greater facial and body hair, and possible premature balding.
andropause in middle-aged males, the rough equivalent to female menopause, with falling testosterone and DHEA levels causing increasing fatigue, fat production, muscle loss, and sleep disturbances.
bioidentical hormone a hormone made from plants such as soy and synthesized to mimic those produced naturally in the human body.
catecholamine a class of hormones, including epi- nephrine, norepinephrine, and dopamine, produced in the adrenal glands and released in stressful situations, as in a fight-or-flight situation or when blood sugar levels are low. Dopamine is also involved in generating the pleasurable feelings that come with rewarding experiences, especially involving food, sex, or drugs.
cortisol produced by the adrenal cortex, a stress hormone that, among other things, raises blood pressure and blood sugar and is involved in the deposition of fat.
DHEA dehydroepiandrosterone, an adrenal gland hormone that is converted to androgens and estrogen and is involved in maintaining stamina and energy levels as well as mental well-being.
dihydrotestosterone a more powerful form of testosterone that acts as a masculinizing force and, among other things, is implicated in male pattern baldness and prostate trouble.
endocrine system collective term for all of the body's glands that produce and secrete hormones.
endocrinology the medical field that deals with the body's glands and the hormones they secrete.
estradiol a form of estrogen that is involved in sexual behavior, breast development, and bone growth. According to the latest scientific studies, women with the highest levels of estradiol tend to have hourglass figures, are more self-confident, and are more likely to cheat on their long-term partners.
estrogen in women, produced primarily in the ovaries, and which includes estradiol, estrsone, and estriol, primarily female hormones responsible for everything from breast development to regulation of the menstrual cycle.
finger length ratio the ratio of length between the ring finger and the index finger, a proven indicator of testosterone exposure during fetal development and the consequent masculinization or feminization of some traits throughout life. Men typically have longer ring than index fingers, while the finger lengths in women are the same or the index finger is slightly longer. Longer ring finger lengths have been strongly correlated with assertiveness, aggressiveness, success in sports and the stock market, along with a higher probability of bisexuality.
