Virilization or masculinization is the biological development of adult male characteristics in young males or females. [1] Most of the changes of virilization are produced by androgens.
Dihydrotestosterone, also known as (DHT) will differentiate the remaining male characteristics of the external genitalia. [11] Further sex differentiation of the external genitalia occurs at puberty, when androgen levels again become disparate. Male levels of testosterone directly induce growth of the penis, and indirectly (via DHT) the prostate.
[14] [15] Although variations exist and there may be a degree of overlap between typically male or female traits, [14] [15] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex. [15] It differs both in overall shape and structure.

[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.
Most studies have also found testosterone to be associated with behaviors or personality traits linked with criminality such as antisocial behavior and alcoholism. [ 57 ] In species that have high levels of male physical competition and aggression over females, males tend to be larger and stronger than females.
Male primary sex characteristics are the penis, the scrotum and the ability to ejaculate when matured. Female primary sex characteristics are the vulva, vagina, uterus, fallopian tubes, cervix, and the ability to give birth and menstruate when matured. [1] Hormones that express sexual differentiation in humans include: estrogens such as estradiol
Research shows that male androgenetic alopecia is the most common form of hair loss in men, affecting as much as 30 to 50 percent of men by age 50. But age isn’t the only factor involved in ...
