The sex hormones

There is a pervasive notion that men and women are quite different when it comes to behavior and temperament—and those extend way beyond the physical differences seen in our nether regions. In fact, neuroscientists have discovered that there are quite noticeable variances between male and female brains, in terms of both structure, volume, and function. And sex hormones, like estrogen and testosterone, can target regions of the brain, affecting many aspects of signaling and function at the epigenetic, cellular, and behavioral levels. Many of us think of hormones as the gender-specific molecules we learned about in middle school health class—the chemical messengers that arrive during puberty to govern our reproductive development. But sex steroids like testosterone and estrogen also play a critical role in brain development even before adolescence: shaping, activating, and fueling sexually dimorphic brain circuits. These circuits are not limited to those involved with romantic and sexual entanglements.

Sex Hormones and the Brain | Dana Foundation

The two main sex hormones — estrogen and testosterone — have wide-ranging effects in the body. Produced primarily by the ovaries estrogen and testes testosterone , these hormones affect not just your sexual function but also your bones, brain, and blood vessels, for example. As people age, the natural decline in sex hormone levels sometimes causes undesirable symptoms, such as hot flashes or a flagging sex drive. Doctors can prescribe pills, patches, gels, and creams containing estrogen or testosterone to ease those symptoms.

Sex hormones and your heart

Hormones are unique chemical messengers in the body. They are made by specialized tissues called glands — examples include the thyroid, pituitary, and adrenal glands, as well as the ovaries and testes. Although hormones are active in very small amounts, they regulate incredibly important aspects of human health, including mood, reproduction, metabolism, and development. Among the most important are the sex hormones.

Sex hormones , also known as sex steroids , gonadocorticoids and gonadal steroids , are steroid hormones that interact with vertebrate steroid hormone receptors. Their effects are mediated by slow genomic mechanisms through nuclear receptors as well as by fast nongenomic mechanisms through membrane-associated receptors and signaling cascades. Natural sex hormones are made by the gonads ovaries or testes , [3] by adrenal glands , or by conversion from other sex steroids in other tissue such as liver or fat. In many contexts, the two main classes of sex hormones are androgens and estrogens, of which the most important human derivatives are testosterone and estradiol , respectively.
