		Sex refers to the male and female duality of biology and reproduction, a process in biological DNA that dates back 4.6 - 3.5 billion years.
		The female sex is definitely defined as the one which produces the larger gamete (i.e., reproductive cell) and which typically bears the offspring.
		An example of this in the article pictogram shows the man with broader shoulders (sex dimorphism) and the woman in clothing that is, in the western world, rarely worn by men, and which functions as a gender signal.

		The gender of the internal sex organs of a fetus is determined by the presence or absence of hormones secreted by the testes.
		The external genitalia are the visible sex organs, including the penis and scrotum in males and the labia, clitoris and the outer part of the vagina in females.

		Sex differences are integrated into all aspects of the human person from one’s physiology and pscho-emotional structure, to his very soul.
		Masculine secondary sex characteristics all serve to facilitate the male’s “reaching out into the world and of overcoming and conquering space.” Female sex characteristics converge in a way in which the woman is more strongly directed toward the inside.
		While the sex characteristics serve a telos, a purpose, they do it in such a way that the masculine primary and secondary characteristics are eccentric, he initiates and goes outward.

	DHT and Hair Loss
		DHT is believed to be the key androgenic hormone, as its primary role is to develop a male’s primary sex characteristics during embryonic life.
		It is also responsible for the development majority of the secondary sex characteristics of males during their puberty stage and continues to play an important role in male sexual function in the latter years of life.
		Characteristically, it binds strongly to the androgen receptor and been shown to be five times more potent compared to testosterone.

		It is apparent that medical determination of sex can be exceptionally complex, and some sort of medical intervention may be needed during the individual’s life to somehow medically align the person’s physical structure to allow one of the binary social genders to be selected and applied.
		Identification of primary and secondary sex characteristics, hormonal balances, gonadal structure, and chromosome/genetic structure are all within the capability of current medical science to determine with relative ease on living individuals.
		This seems to occur independently of other medical sex characteristics, although it is plausible that it may be related to "brain sex" of the individual.

	Transsexualism - Psychology Wiki - A Wikia wiki
		To obtain sex reassignment therapy, transsexual people are usually required to receive psychological therapy and a diagnosis of gender identity disorder.
		The term currently in widest use for modification of primary sex characteristics is sex reassignment surgery (SRS), a term which reflects the belief that transsexual people do not consider themselves to be changing their sex, but to be correcting their bodies.
		However, since sex in humans is composed of many different attributes, such as genes, chromosomes, regulatory proteins, hormones, hormone receptors, body morphology, brain sex, and gender identity, any variation among any of those attributes falls under the rubric of "intersex." Transsexualism, in this view, simply becomes neurological intersexuality.

		Remembering your own discomfort on his behalf, recognize that the primary and more intense suffering was his alone; just as it is he who now bears the heaviest burdens of readjustment to a new life.

		The financial burdens of sex reassignment, the cost of surgery and other surgery, the loss of income during the period of recuperation, may present the transsexual with a difficult or insurmountable problem.

		In fact, the physical observation of the two sexes we call "men" and "women" in nature is the result of differences in the amounts of individual hormones in the body and differences in their patterns of secretion (first in utero and then again during puberty) rather than their presence or absence.
		Endocrinologists classify sex hormones as being in the family of "steroid hormones"--derivatives of cholesterol that are synthesized mainly by the gonads and, in smaller amounts, the adrenal gland.
		"Primary sex characteristics" refer to physical characteristics present in the human body that are directly involved in reproductive function: namely the gonads and their accessory structures.

		A dramatic rise in sex hormones and in the hormones that govern their release occur in early adolescence.
		Sex Hormones Males: Androgens->tissues that form the male reproductive organs are more sensitive to androgens Females: Estrogens-> tissues that form the male reproductive organs are more sensitive to estrogens.
		Gonads: are the sex glands-> Ovaries (females); Testes (males) A Feedback System->the level at which hormones circulate in the bloodstream is controlled by a delicate feedback system involving the hypothalamus, the anterior pituitary, and the gonads.
