Do people with AIS have periods?
A person with complete AIS appears to be female but has no uterus. They have very little armpit and pubic hair. At puberty, female sex characteristics (such as breasts) develop. However, the person does not menstruate and become fertile.
Can males be genetically female?
Indeed it can. A gene on the X chromosome (the chromosome one typically associates with “femaleness”) called DAX1 when present in double copy in a male (XY) mouse, turns it into a female.
How common is testicular feminization?
The incidence of testicular feminization syndrome is reported to range between one in 2,000 to one in 62,400 [2].
Do babies pee in the womb?
Do babies pee in the womb? While babies most often hold out on pooping until they’re born, they are certainly active urinators in the womb. In fact, your baby’s pee activity goes into overdrive between 13 and 16 weeks’ gestation, when their kidneys are fully formed.
How many sexes are there?
Based on the sole criterion of production of reproductive cells, there are two and only two sexes: the female sex, capable of producing large gametes (ovules), and the male sex, which produces small gametes (spermatozoa).
How many genders are there?

What is feminization syndrome?
AIS is a disorder of sex differentiation. It was previously called testicular feminization syndrome. It affects male fetuses as they develop in the womb, as well as sexual development during puberty. AIS prevents male genitals from developing as they should. It almost always results in infertility during adulthood.
How common is testicular feminisation?
The incidence of testicular feminization syndrome is reported to range between one in 2,000 to one in 62,400 [2].
Are men going extinct?
Men may not become extinct after all, according to a new study. Previous research has suggested the Y sex chromosome, which only men carry, is decaying genetically so fast that it will be extinct in five million years’ time.
Can female have testes?
Some women have testes, organs that produce testosterone, because they are trans women or they have an intersex state.
