In psychology, libido is psychic drive or energy, usually conceived as sexual in nature, but sometimes conceived as including other forms of desire. The term libido was originally used by the neurologist and pioneering psychoanalyst Sigmund Freud who began by employing it simply to denote sexual desire. Over time it came to signify the psychic energy of the sexual drive, and became a vital concept in psychoanalytic theory. Freud's later conception was broadened to include the fundamental energy of all expressions of love, pleasure, and self-preservation.
A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse. The cell receiving the signal, or target cell, may be another neuron, but could also be a gland or muscle cell.
Adolescence is a transitional stage of physical and psychological development that generally occurs during the period from puberty to adulthood. Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier or end later. Puberty typically begins during preadolescence, particularly in females. Physical growth and cognitive development can extend past the teens. Age provides only a rough marker of adolescence, and scholars have not agreed upon a precise definition. Some definitions start as early as 10 and end as late 30. The World Health Organization definition officially designates an adolescent as someone between the ages of 10 and 19.
Enjo kōsai, shortened to enkō (援交), is a type of transactional relationship similar to the Western sugar dating. It is the Japanese language term for the practice of older men giving money and/or luxury gifts to attractive young women for sexual favors. The female participants range from school girls to housewives. The term is often translated as "compensated dating" or "subsidized dating".
Sex differences in psychology are differences in the mental functions and behaviors of the sexes and are due to a complex interplay of biological, developmental, and cultural factors. Differences have been found in a variety of fields such as mental health, cognitive abilities, personality, emotion, sexuality, friendship, and tendency towards aggression. Such variation may be innate, learned, or both. Modern research attempts to distinguish between these causes and to analyze any ethical concerns raised. Since behavior is a result of interactions between nature and nurture, researchers are interested in investigating how biology and environment interact to produce such differences, although this is often not possible.
Neuropharmacology is the study of how drugs affect function in the nervous system, and the neural mechanisms through which they influence behavior. There are two main branches of neuropharmacology: behavioral and molecular. Behavioral neuropharmacology focuses on the study of how drugs affect human behavior (neuropsychopharmacology), including the study of how drug dependence and addiction affect the human brain. Molecular neuropharmacology involves the study of neurons and their neurochemical interactions, with the overall goal of developing drugs that have beneficial effects on neurological function. Both of these fields are closely connected, since both are concerned with the interactions of neurotransmitters, neuropeptides, neurohormones, neuromodulators, enzymes, second messengers, co-transporters, ion channels, and receptor proteins in the central and peripheral nervous systems. Studying these interactions, researchers are developing drugs to treat many different neurological disorders, including pain, neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease, psychological disorders, addiction, and many others.
A girl is a young female human, usually a child or an adolescent. When a girl becomes an adult, she is generally referred to as a woman. However, the term girl is also used for other meanings, including young woman, and is sometimes used as a synonym for daughter or girlfriend regardless of age. In certain contexts, the usage of the term girl for an adult woman may be considered derogatory. Girl may also be a term of endearment used by an adult, usually a woman, to designate adult female friends. Girl also appears in compounds like showgirl, cowgirl, and schoolgirl.

She is a biological anthropologist, is a senior research fellow, at The Kinsey Institute, Indiana University, and a member of the Center For Human Evolutionary Studies in the Department of Anthropology at Rutgers University. Prior to Rutgers University, she was a research associate at the American Museum of Natural History in New York City.
The Female Brain is a book written by the American neuropsychiatrist Louann Brizendine in 2006. The main thesis of the book is that women's behavior is different from that of men due, in large measure, to hormonal differences. Brizendine says that the human female brain is affected by the following hormones: estrogen, progesterone, testosterone, oxytocin, neurotransmitters, and that there are differences in the architecture of the brain that regulate such hormones and neurotransmitters.
Adolescent sexuality is a stage of human development in which adolescents experience and explore sexual feelings. Interest in sexuality intensifies during the onset of puberty, and sexuality is often a vital aspect of teenagers' lives. Sexual interest may be expressed in a number of ways, such as flirting, kissing, masturbation, or having sex with a partner. Sexual interest among adolescents, as among adults, can vary greatly, and is influenced by cultural norms and mores, sex education, as well as comprehensive sexuality education provided, sexual orientation, and social controls such as age-of-consent laws.
Leonard Sax is an American psychologist and family physician. He is the author of three books for parents: Boys Adrift, Girls on the Edge, and Why Gender Matters. According to his website, he is currently employed as a physician at a healthcare facility in Chester County, Pennsylvania, where he also resides.
The 5-HT2C receptor is a subtype of the 5-HT2 receptor that binds the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, it is a G protein-coupled receptor (GPCR) that is coupled to Gq/G11 and mediates excitatory neurotransmission. HTR2C denotes the human gene encoding for the receptor, that in humans is located on the X chromosome. As males have one copy of the gene and females have one of the two copies of the gene repressed, polymorphisms at this receptor can affect the two sexes to differing extent.
Sex differences in education are a type of sex discrimination in the education system affecting both men and women during and after their educational experiences. Men are more likely to be literate on a global average, although higher literacy scores for women are prevalent in many countries. Women are more likely to achieve a tertiary education degree compared to men of the same age. Men tended to receive more education than women in the past, but the gender gap in education has reversed in recent decades in most Western countries and many non-Western countries.
Feminist psychology is a form of psychology centered on social structures and gender. Feminist psychology critiques historical psychological research as done from a male perspective with the view that males are the norm. Feminist psychology is oriented on the values and principles of feminism.
Cordelia Fine is a Canadian-born British philosopher of science, psychologist, and writer. She is a full professor in the History and Philosophy of Science programme at the University of Melbourne, Australia.

Her latest book, Testosterone Rex, won the Royal Society Science Book Prize, 2017. She has authored several academic book chapters and numerous academic publications. Fine is also noted for coining the term 'neurosexism'.
The reward theory of attraction claims that people are attracted to individuals exhibiting behaviors that are rewarding to them or whom they associate with rewarding events. Individuals seek to develop strong relationships with those who provide positive and fulfilling interactions that require little to nothing in return.
Sex differences in human intelligence have long been a topic of debate among researchers and scholars. It is now recognized that there are no significant sex differences in general intelligence, though particular subtypes of intelligence vary somewhat between sexes.
Daphna Joel is an Israeli neuroscientist and advocate for "neurofeminism". She is best known for her research which claims that there is no such thing as a "male brain" or a "female brain". Joel's research has been criticized by other neuroscientists who argue that male and female brains, on average, show distinct differences and can be classified with a high level of accuracy. Joel is a member of The NeuroGenderings Network, an international group of researchers in gender studies and neuroscience. They are critical of what they call neurosexism in the scientific community. Joel has given lectures on her work in both scientific and lay conventions around the world.
Melissa Hines is a neuroscientist and Professor at the University of Cambridge. She studies the development of gender, with particular focus on how the interaction of prenatal and postnatal experience shape brain development and behavior.
Neurosexism is an alleged bias in the neuroscience of sex differences towards reinforcing harmful gender stereotypes. The term was coined by feminist scholar Cordelia Fine in a 2008 article and popularised by her 2010 book Delusions of Gender. The concept is now widely used by critics of the neuroscience of sex differences in neuroscience, neuroethics and philosophy.
