	Sex steroid - Wikipedia, the free encyclopedia
		Sex steroids, also known as gonadal steroids, are steroid hormones which interact with vertebrate androgen or estrogen receptors.
		Natural sex steroids are made by the gonads (ovaries or testes), by adrenal glands, or by conversion from other sex steroids in other tissues such as liver or fat.
		The development of both primary and secondary sexual characteristics is controlled by sex hormones after the initial fetal stage where the presence or absence of the Y-chromosome and/or the SRY gene determine development.

	Hormone - Wikipedia, the free encyclopedia
		Hormone molecules are secreted (released) directly into the bloodstream; some hormones, called ectohormones, aren't secreted into the blood stream, they move by circulation or diffusion to their target cells, which may be nearby cells (paracrine action) in the same tissue or cells of a distant organ of the body.
		The function of hormones is to serve as a signal to the target cells; the action of hormones is determined by the pattern of secretion and the signal transduction of the receiving tissue.
		A recently-identified class of hormones is that of the "Hunger Hormones" - ghrelin, orexin and PYY 3-36 - and "Satiety hormones" - e.g., leptin, obestatin.

	Sex Hormones in the Male Brain: Is There an Effect on Cognition?
		Sex hormone concentrations were more often associated with measures of brain volume than with measures of cognitive task performance —results that have larger implications for current clinical practice in neurology, said Christina Lessov, PhD.
		Because of the different composition of sex hormones between women and men, one active hypothesis is that differences in sex hormone concentrations may help account for the differences seen in cognitive performance.
		As to why estrone emerged as the sex hormone of greatest significance in this study, the explanation is unclear, and Dr. Lessov and her colleagues are now pursuing this line of inquiry; a manuscript with updated and more thorough analysis is near completion.

		Hormones are the chemical messengers in the body that control many functions but especially those concerned with sexual development, reproduction and growth.
		Testosterone was soon recognized as a sex hormone that had muscle building properties and ever since body builders, weight lifters and athletes have used anabolic steroids to gain strength, weight and muscle mass.
		For example, progesterone is an important precursor in the biosynthesis of adrenal corticosteroids (hormones that protect against stress) and of all sex hormones (testosterone and estrogen).

	IJ TRANSGENDER - Effects of Cross-Sex Hormone Treatment on Emotionality in Transsexuals
		The aim of the study was to investigate whether cross-sex hormone treatment in transsexuals affected the intensity of negative and positive emotions in general, and aggressive and sexual feelings in particular.
		There are indications that, in addition to same-sex hormones, cross-sex hormones (testosterone in women, estrogens in men) contribute to the expression of sex-dimorphic behaviors in adulthood, for instance aggression and sexual motivation (Archer, 1991; Van de Poll and Van Goozen, 1992).
		After three months of hormone treatment, sex hormone levels of transsexuals are in the range of those of the opposite sex (Meyer et al., 1986).

	BodyBuilding4Life - Sex Hormone Binding Globulin (shbg)
		Sex hormone binding globulin (SHBG) is a ß-globulin that transports testosterone, dihydrotestosterone (DHT), and estradiol in plasma.
		Free testosterone is calculated using measurements for total testosterone and sex hormone-binding globulin, while the bioavailable testosterone is calculated using measured total testosterone, sex hormone-binding globulin, and albumin.
		Because SHBG levels are altered by medications, disease, aging, sex steroids, and insulin, measurement of free testosterone or bioavailable testosterone more accurately reflects the level of bioactive testosterone than does the measurement of total serum testosterone.

		In adults, elevated levels of sex hormones are associated with an increase in breast cancer risk.
		The researchers measured blood sex hormone levels at the start of the study and 1, 3, 5, and 7 years later.
		Although their study found that a low-fat diet resulted in reductions in estrogen hormone concentrations, the authors say that "whether these differences ultimately influence breast cancer risk is unknown." A parallel study was conducted in boys, and results will be reported separately.

	Sex hormone levels not linked to low sexual desire (Site not responding. Last check: 2007-10-31)
		No single androgen (sex hormone) level was found to be predictive of low sexual function in women, according to a study in the July 6 issue of JAMA.
		Rather, our data, taken together with what is already known about the intracrine [a type of hormone function] physiology, suggest that sex steroids influence female sexual function, but that there is no serum androgen level that defines female androgen insufficiency.
		The measurement of serum testosterone, free testosterone, or DHEAS in individuals presenting with low sexual function is not informative and levels of these hormones should not be used for the purpose of diagnosing androgen insufficiency in women," the researchers conclude.
