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.
Many other genes found on other autosomes, including WT1, SOX9 and SF1 also play a role in gonadal development. [9] Females: Without testosterone and AMH, the mesonephric ducts degenerate and disappear. The paramesonephric ducts develop into the uterus, fallopian tubes, and upper vagina (the lower vagina develops from the urogenital sinus). [9]
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.
Gender, on the other hand, is the social and psychological sense one carries of being male, female or any of the multitude of gender identities said to exist outside of the conventional ...
A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. [1] Most organisms that create their offspring using sexual reproduction have two common sexes, males and females , and in other species, there are hermaphrodites , organisms that can function reproductively as either ...
Other influential academic works focused on the development of gender. In 1966, The Development of Sex Differences was published by Eleanor E Maccoby. [17] This book went into what factors influence a child's gender development, with contributors proposing the effects of hormones, social learning, and cognitive development in respective chapters.
Offspring have two sex chromosomes: an offspring with two X chromosomes (XX) will develop female characteristics, and an offspring with an X and a Y chromosome (XY) will develop male characteristics, except in various exceptions such as individuals with Swyer syndrome, that have XY chromosomes and a female phenotype, and de la Chapelle Syndrome ...
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.
