  2. Sex differences in human physiology - Wikipedia

    en.wikipedia.org/wiki/Sex_differences_in_human...

    Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These differences are caused by the effects of the different sex chromosome complement in males and females, and differential exposure to gonadal sex hormones during development.

    The human Y chromosome showing the SRY gene which codes for a protein regulating sexual differentiation. Sexual differentiation in humans is the process of development of sex differences in humans. It is defined as the development of phenotypic structures consequent to the action of hormones produced following gonadal determination. [1]

    Gender-based medicine, also called "gender medicine", is the field of medicine that studies the biological and physiological differences between the human sexes and how that affects differences in disease. Traditionally, medical research has mostly been conducted using the male body as the basis for clinical studies.

    Our society has convinced us that there are just two options for gender identity, "male" and "female," based on biological sex. But in reality, there's more fluidity. Gender identity is on a ...

    en.wikipedia.org/wiki/Sex–gender_distinction

    The authors differentiate between sex differences, caused by biological factors, and gender differences, which "reflect a complex interplay of psychological, environmental, cultural, and biological factors". [14] Gender identity is thus seen as a "psychological concept that refers to an individual's self-perception". [14] Other studies have ...

    en.wikipedia.org/wiki/XY_sex-determination_system

    In humans, most mammals, and some other species, two of the chromosomes, called the X chromosome and Y chromosome, code for sex. In these species, one or more genes are present on their Y chromosome that determine maleness.

  8. Sexual differentiation - Wikipedia

    en.wikipedia.org/wiki/Sexual_differentiation

    Sexual differentiation is the process of development of the sex differences between males and females from an undifferentiated zygote. [1] [2] Sex determination is often distinct from sex differentiation; sex determination is the designation for the development stage towards either male or female, while sex differentiation is the pathway towards the development of the phenotype.

  9. Sex-limited genes - Wikipedia

    en.wikipedia.org/wiki/Sex-limited_genes

    However, the resulting phenotypes caused by sex-limited genes are present in only one sex and can be seen prominently in various species that typically show high sexual dimorphism. [ 2 ] Sex-limited genes are responsible for sexual dimorphism , which is a phenotypic (directly observable) difference between males and females of the same species ...
