Pregnancy, Birth and Abortion is a 1958 book about human pregnancy by the anthropologist Paul Gebhard, the sexologist Wardell Pomeroy, the sexologist Clyde Martin, and Cornelia Christenson.
 It was a publication of the Institute for Sex Research.
 The work was prepared and written with careful attention to sampling, methodology and date interpretation, to demonstrate the Institute for Sex Research's scientific competence despite the death of Alfred Kinsey and to answer the criticism that the Institute was interested only in popular, moneymaking books.
 Though it did not receive the public acceptance of "Sexual Behavior in the Human Male" and "Sexual Behavior in the Human Female", the work was well received in scientific circles, and demonstrated that the Institute could survive as a productive research organization.

The historical concept and definition of sexual orientation varies and has changed greatly over time; for example the word "gay" was not used to describe sexual orientation until the mid 20th century.
 A number of different classification schemes have been used to describe sexual orientation since the mid-19th century, and scholars have often defined the term "sexual orientation" in divergent ways.
 Indeed, several studies have found that much of the research about sexual orientation has failed to define the term at all, making it difficult to reconcile the results of different studies.
 However, most definitions include a psychological component (such as the direction of an individual's erotic desire) and/or a behavioural component (which focuses on the sex of the individual's sexual partner/s).
 Some prefer to simply follow an individual's self-definition or identity.
Alfred Charles Kinsey ( ; June 23, 1894 – August 25, 1956) was an American biologist, professor of entomology and zoology, and sexologist who in 1947 founded the Institute for Sex Research at Indiana University, now known as the Kinsey Institute for Research in Sex, Gender, and Reproduction.
 He is best known for writing "Sexual Behavior in the Human Male" (1948) and "Sexual Behavior in the Human Female" (1953), also known as the Kinsey Reports, as well as the Kinsey scale.
 Kinsey's research on human sexuality, foundational to the field of sexology, provoked controversy in the 1940s and 1950s.
 His work has influenced social and cultural values in the United States, as well as internationally.

 The sixth Director of The Kinsey Institute for Research in Sex, Gender, and Reproduction at Indiana University, she began on June 1, 2004.
 Dr. Heiman is also a professor in the Psychology Department at Indiana University with a joint appointment in the Psychiatry Department at the IU School of Medicine in Indianapolis.
The Kinsey scale, also called the Heterosexual–Homosexual Rating Scale, is used in research to describe a person's sexual orientation based on their experience or response at a given time.
 The scale typically ranges from 0, meaning exclusively heterosexual, to 6, meaning exclusively homosexual.
 In both the Male and Female volumes of the "Kinsey Reports", an additional grade, listed as "X", was used to mean "no socio-sexual contacts or reactions".
 The reports were first published in "Sexual Behavior in the Human Male" (1948) by Alfred Kinsey, Wardell Pomeroy and others, and were also prominent in the complementary work "Sexual Behavior in the Human Female" (1953).

Scales of sexual orientation are classification schemes of different sexual orientations. Definitions of the term "sexual orientation" normally include two components: the "psychological" and the "behavioral" component, but the definitions of the two components vary between researchers and across time.
 Those difficulties motivate researchers to define scales to measure and describe sexual orientation.
 Most sexual behavior and sexual orientation scales are motivated by the view that sexual orientation is a continuum.
 The Kinsey scale works from a continuum viewpoint and is the most prevalent sexual orientation scale.
The Kinsey Reports are two books on human sexual behavior, Sexual Behavior in the Human Male (1948) and Sexual Behavior in the Human Female (1953), written by Alfred Kinsey, Paul Gebhard, Wardell Pomeroy and others and published by Saunders.
 Kinsey was a zoologist at Indiana University and the founder of the Kinsey Institute for Research in Sex, Gender, and Reproduction (more widely known as the Kinsey Institute).
The Sex Orientation Scale (SOS) was Harry Benjamin's attempt to classify and understand various forms and subtypes of transvestism and transsexualism in biological males, published in 1966.
 It was a seven-point scale (with three types of transvestism, three types of transsexualism, and one category for typical males); it was analogous to the Kinsey Scale as it relates to sexual orientation, which also had seven categories.
 Much like Kinsey's understanding of sexual orientation, Benjamin understood the nature of gender identity and gender expression not as a discrete scale, but as a spectrum, a continuum with many variations.
 However the Benjamin scale does not reflect a modern understanding of gender identity and is not useful as a contemporary diagnostic tool, especially due to its conflation of gender identity with sexual orientation.
