As many as 1 person in 100 has some form of “DSD,” a difference/disorder of sex development.
The simple scenario many of us learned in school is that two X chromosomes make someone female, and an X and a Y chromosome make someone male.
According to the feature, true intersex disorders, such as those from divergent genes or the inability of cellular receptors to respond to hormones, yield conflicting chromosomal and anatomical sex.
Imagine being a forty-six-year-old woman pregnant with her third child, whose amniocentesis follow-up shows that half her cells carry male chromosomes.
Or a seventy-year-old father of three who learns during a hernia repair that he has a uterus. People can be sexed in a non-straightforward way and not even be aware of it; in fact, most probably aren’t.
An extremely common instance of mosaicism comes from cells passing over the placental barrier during pregnancy.
Men often carry female cells from their mothers, and women carry male cells from their sons.
(Alice Dreger explores this question in greater depth in her book Hermaphrodites and the Medical Invention of Sex.) Here’s what we do know: If you ask experts at medical centers how often a child is born so noticeably atypical in terms of genitalia that a specialist in sex differentiation is called in, the number comes out to about 1 in 1500 to 1 in 2000 births.
But a lot more people than that are born with subtler forms of sex anatomy variations, some of which won’t show up until later in life. We were recently asked to update these frequency figures, and a lively discussion arose between two staff members.These are simplistic ways of thinking about what is scientifically very complex.Anatomy, hormones, cells, and chromosomes (not to mention personal identity convictions) are actually not usually aligned with one binary classification. As quoted in the article, Eric Vilain, MD, Ph D, director of the Center for Gender-Based Biology at UCLA, explains that sex determination is a contest between two opposing networks of gene activity.Note that the frequency of some of these conditions, such as congenital adrenal hyperplasia, differs for different populations.
