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.
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, [46] 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". [47]
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.
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 ...
Determination of sex is a process by which scientists and medical professionals determine the biological sex of a person or other animal using genetics and biological sexual traits. It is not to be confused with sex assignment which is a more recent colloquial term that allows for the use of non-sexual or non-genetic traits to define a person's ...
Sexual characteristics are physical traits of an organism (typically of a sexually dimorphic organism) which are indicative of or resultant from biological sexual factors. These include both primary sex characteristics, such as gonads, and secondary sex characteristics.
