Gender Taxonomy
The gender taxonomy is a classification of the range of different levels at which humans vary in sexual characteristics. It is mainly used by medical specialists working in the area of sex research. "A review of cross-gender taxonomies shows that previous observers have identified and labeled a homosexual type far more consistently than any other category of male gender dysphoric." Ray Blanchard,The classification and labeling of nonhomosexual gender dysphorias, ''Archives of Sexual Behavior'' 18/4 (1989): 315–334. John Money and Milton Diamond are probably the best known researchers in this field. Money earned his PhD for research into human hermaphroditism and pseudohermaphroditism, now known as intersex conditions. The taxonomy starts at the simplest, biological level and traces differentiations expressed at the increasingly complicated levels produced over the course of the human life cycle Life cycle, life-cycle, or lifecycle may refer to: Science and academia *Biologica ...

Taxonomic Classification
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolut ...

Human
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically moder ...

Sexual Characteristics
Sexual characteristics are physical traits of an organism (typically of a sexually dimorphic organism) which are indicative of its biological sex. These can include sex organs used for reproduction and secondary sex characteristics which distinguish the sexes of a species, but which are not directly part of the reproductive system. Humans In humans, sex organs or primary sexual characteristics, which are those a person is born with, can be distinguished from secondary sex characteristics, which develop later in life, usually during puberty. The development of both is controlled by sex hormones produced by the body after the initial fetal stage where the presence or absence of the Y-chromosome and/or the SRY gene determine development. Hormones that express sexual differentiation in humans include: * estrogens * progesterone * androgens such as testosterone Typical sexual characteristics The following table lists the typical sexual characteristics in humans: Invertebr ...

Sexology
Sexology is the scientific study of human sexuality, including human sexual interests, behaviors, and functions. The term ''sexology'' does not generally refer to the non-scientific study of sexuality, such as social criticism. Sexologists apply tools from several academic fields, such as anthropology, biology, medicine, psychology, epidemiology, sociology, and criminology. Topics of study include sexual development (puberty), sexual orientation, gender identity, sexual relationships, sexual activities, paraphilias, and atypical sexual interests. It also includes the study of sexuality across the lifespan, including child sexuality, puberty, adolescent sexuality, and sexuality among the elderly. Sexology also spans sexuality among those with mental or physical disabilities. The sexological study of sexual dysfunctions and disorders, including erectile dysfunction and anorgasmia, are also mainstays. History Early Sex manuals have existed since antiquity, such as Ovid's ''Ars ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray Blanchard
Ray Milton Blanchard ( ; born October 9, 1945) is an American-Canadian sexologist, best known for his research studies on transsexualism, pedophilia and sexual orientation. He found that men with more older brothers are more likely to be gay than men with fewer older brothers, a phenomenon he attributes to the reaction of the mother's immune system to male fetuses. Blanchard has also published research studies on phallometry and several paraphilias, including autoerotic asphyxia. Education and career Blanchard was born in Hammonton, New Jersey. He received his A.B. in Psychology from the University of Pennsylvania in 1967 and his Ph.D. from the University of Illinois in 1973. He conducted postdoctoral research at Dalhousie University until 1976, when he accepted a position as a clinical psychologist at the Ontario Correctional Institute in Brampton, Ontario, Canada (a suburb of Toronto). There, Blanchard met Kurt Freund, who became his mentor. Freund was conducting research in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Money
John William Money (8 July 1921 – 7 July 2006) was a New Zealand psychologist, sexologist and author known for his research into sexual identity and Sex determination and differentiation (human), biology of gender. He was one of the first researchers to publish theories on the influence of societal constructs of gender on individual formation of gender identity. Money introduced the terms ''gender role'' and ''sexual orientation'' and popularised the terms ''gender identity'' and ''paraphilia''. Working with endocrinologist Claude Migeon, Money established the Johns Hopkins Gender Identity Clinic, the first clinic in the United States to perform sexual reassignment surgeries on both infants and adults. He spent a considerable amount of his career in the United States. A 1997 academic study criticised Money's work in many respects, particularly in regard to the involuntary sex-reassignment of the child David Reimer. Reimer committed suicide at 38 and his brother died of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milton Diamond
Milton Diamond (born March 6, 1934) is an American Professor Emeritus of anatomy and reproductive biology at the University of Hawaiʻi at Mānoa. After a career in the study of human sexuality, Diamond retired from the university in December 2009 but continued with his research and writing until retiring fully in 2018. Early career Milton Diamond graduated from the City College of New York with a BS in biophysics in 1955, after which he spent three years in the Army as an engineering officer, stationed in Japan. On returning to the United States, he attended graduate school at University of Kansas from 1958–1962 and earned a PhD in anatomy and psychology from that University. His first job was teaching at the University of Louisville, School of Medicine where he simultaneously completed two years toward an MD, passing his Basic Medicine Boards, and in 1967 he moved to Hawaii to take up a post at the recently established John A.

Doctorate
A doctorate (from Latin ''docere'', "to teach"), doctor's degree (from Latin ''doctor'', "teacher"), or doctoral degree is an academic degree awarded by universities and some other educational institutions, derived from the ancient formalism ''licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. In the United States and some other countries, there are also some types of technical or professional degrees that include "doctor" in their name and are classified as a doctorate in some of those countries. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. Many universities also award honorary doctorates to individuals d ...

Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many Taxonomy (biology), taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicata, tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called Gonochorism, gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species ( ...

Pseudohermaphroditism
Pseudohermaphroditism is a condition in which an individual has a matching chromosomal and gonadal tissue (ovary or testis) sex, but mismatching external genitalia. Female pseudohermaphroditism refers to an individual with ovaries and external genitalia resembling those of a male. Male pseudohermaphroditism refers to an individual with testes and external genitalia resembling those of a female. In some cases, external sex organs associated with pseudohermaphroditism appear intermediate between a typical clitoris and penis. Thus, pseudohermaphroditism is sometimes not identified until puberty or adulthood. The term contrasts with true hermaphroditism, a condition describing an individual with both female and male reproductive organs. Associated conditions include 5-α-reductase deficiency and androgen insensitivity syndrome. Mechanism Sex is determined by chromosomes during fertilization. In the early stages of human development, a human embryo has the precursors of female (p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intersex
Intersex people are individuals born with any of several sex characteristics including chromosome patterns, gonads, or genitals that, according to the Office of the United Nations High Commissioner for Human Rights, "do not fit typical binary notions of male or female bodies". Sex assignment at birth usually aligns with a child's anatomical sex and phenotype. The number of births with ambiguous genitals is in the range of 1:2000–1:4500 (0.022%–0.05%). Other conditions involve atypical chromosomes, gonads, or hormones. Some persons may be assigned and raised as a girl or boy but then identify with another gender later in life, while most continue to identify with their assigned sex. The number of births where the baby is intersex has been reported differently depending on who reports and which definition of intersex is used. Anne Fausto-Sterling and her co-authors suggest that the prevalence of "nondimorphic sexual development" might be as high as 1.7%. A study publish ...
