Every genetically-male human has a female-like sex organ until about the seventh week of pregnancy1, then, in general, due to male chromosomes' effect → androgens would be produced and cause that organ to change into male sexual organs1.
Such a course may be "biased" (for lack of a better term) towards intersexuality, in each of these contexts:
- True hermaphoriditism
- Androgen insensitivity, partial or complete
- Non androgen insensitivity "feminization" in at least one aspect (for example gender dysphoria in the apparently genetically-male)
What are the types of human intersexuality (are these the only types)?
