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 .
In humans, the presence of the Y chromosome is responsible for triggering male development; in the absence of the Y chromosome, the fetus will undergo female development, except with various exceptions such as individuals with Swyer syndrome, that have XY chromosomes and a female phenotype, and de la Chapelle Syndrome, that have XX chromosomes ...
The common pathway of sexual differentiation, where a productive human female has an XX chromosome pair, and a productive male has an XY pair, is relevant to the development of intersex conditions. During fertilization, the sperm adds either an X (female) or a Y (male) chromosome to the X in the ovum. This determines the genetic sex of the embryo.
Individuals can either have sex chromosomes generally linked with being female (XX chromosomes) or usually associated with being a man (XY chromosomes), yet have reproductive organs and genitals ...
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]
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 ...
However, IBA president Umar Kremlev told the Russian news agency Tass last year that the disqualifications were because “it was proven they have XY chromosomes.”
Women first competed at the Olympic Games in 1900, with an increased programme available for women to enter from 1924. [9] Prior to 1936, sex verification may have been done ad hoc, but there were no formal regulations; [2] the existence of intersex people was known about, though, and the Olympics began "dealing with" – acknowledged and sought to regulate [1] – intersex athletes ahead of ...
