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.
Biological differentiation is a fundamental part of human reproduction. Generally, males have two different sex chromosomes, an X and a Y; females have two X chromosomes. The Y chromosome, or more precisely the SRY gene located on it, is what generally determines sexual differentiation. If a Y chromosome with an SRY gene is present, growth is ...
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.
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.
Looking into the genetic determinants of human sex can have wide-ranging consequences. Scientists have been studying different sex determination systems in fruit flies and animal models to attempt an understanding of how the genetics of sexual differentiation can influence biological processes like reproduction, ageing [24] and disease.
Biological sex is different and doesn't need to match one's gender. T.E.R.F.: T.E.R.F. is an acronym for trans-exclusionary radical feminist, which means someone who excludes trans women and non ...
Robert Stoller, whose work was the first to treat sex and gender as "two different orders of data", in his book Sex and Gender: The Development of Masculinity and Femininity, [47] uses the term 'sex' to refer to the "male or the female sex and the component biological parts that determine whether one is a male or a female".
