Are masculinization and Defeminization the same?
The process of masculinization is often coupled with a similar process, defeminization, which removes feminine behavioral and morphological characteristics of the brain and behavior.
What masculinization means?
Definition of masculinize transitive verb. : to give a chiefly masculine character to especially : to cause (a female) to take on male characteristics.
What is the process of Defeminization all about?
noun. (in a developing organism) the process in which full development into a female of the species is prevented because of a male developmental characteristic. there are separate components of the nervous system that control masculinization and defeminization. the removal of feminine qualities.
What does it mean to Masculinize the brain?
Masculinization is the organization of a neural substrate permissive to the adult expression of male sexual behavior. Defeminization is the loss of capacity as an adult to respond to the activational effects of estradiol and progesterone to induce female sex behavior.
What is it called when testosterone turns into estrogen?
Abstract. Estrogens are generated mainly by the action of aromatase, which converts testosterone to estradiol and androstenedione to estrone.
What is the difference between masculinization and virilization?
The noun form of “virilize” is “virilization.” “Virilize” and “virilization” are not to be confused with “masculinize” and “masculinization” which refer to the development of male characteristics in a male on a normal schedule during or on a precocious schedule in a younger boy.
What causes Virilism?
Virilization is typically caused by an imbalance in sex hormones. This may result from using male hormone supplements or anabolic steroids. It can also be caused by an underlying medical condition, like adrenal cancer.
What hormone influences the masculinization of the human brain?
Thus, testosterone appears to serve a dual role: it activates its receptor, the androgen receptor (AR), in neural circuits that control male behaviors, and it also serves as a precursor for estrogen, which in turn influences neural circuits via the estrogen receptors.
What hormone causes masculinization in females?
The masculinization of these neural pathways is independent of AR but can be induced in neonatal females by testosterone or estrogen, indicating that aromatase plays an important role in the sexual differentiation of these neurons.
