XY complete gonadal dysgenesis, also known as Swyer syndrome, is a type of defect hypogonadism in a person whose karyotype is 46,XY. Though they typically have normal vulvas, [1] the person has underdeveloped gonads, fibrous tissue termed "streak gonads", and if left untreated, will not experience puberty. The cause is a lack or inactivation of ...
v. t. e. Disorders of sex development (DSDs), also known as differences in sex development or variations in sex characteristics (VSC), [2] [3] are congenital conditions affecting the reproductive system, in which development of chromosomal, gonadal, or anatomical sex is atypical. [4] DSDs is a clinical term used in some medical settings for ...
The XY sex-determination system is a sex-determination system present in many mammals, including humans, some insects (Drosophila), some snakes, some fish (guppies), and some plants (Ginkgo tree). In this system, the sex of an individual usually is determined by a pair of sex chromosomes. Typically, females have two of the same kind of sex ...
She told Good Morning Britain, "Genetically, I have XY chromosomes so the genetic makeup of a man, but physically I grew as a woman because the Y chromosome was faulty. I am a woman, I just didn't ...
These women would not have periods unless they are given sex hormones, he explained, adding that he has never encountered or heard of a woman with an XY chromosome who can have children. Show comments
Most mammals, including humans, have an XY sex-determination system: the Y chromosome carries factors responsible for triggering male development. In the absence of a Y chromosome, the fetus will undergo female development. This is because of the presence of the sex-determining region of the Y chromosome, also known as the SRY gene. [5]

Sex chromosomes (also referred to as allosomes, heterotypical chromosome, gonosomes, heterochromosomes, [1][2] or idiochromosomes[1]) are chromosomes that carry the genes that determine the sex of an individual. The human sex chromosomes are a typical pair of mammal allosomes. They differ from autosomes in form, size, and behavior.
