In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. Hormone levels in the male parent affect the sex ratio of sperm in humans. [25]
This condition used to be called "male pseudohermaphroditism". This is defined as incomplete masculinization of the external genitalia. [206] Thus, the person has male chromosomes, but the external genitals are incompletely formed, ambiguous, or clearly female. [199] [207] This condition is also called 46, XY with undervirilization.
Intersex people are born with sex characteristics, such as genitals, gonads and chromosome patterns that, according to the UN Office of the High Commissioner for Human Rights, "do not fit the typical definitions for male or female bodies". [1] [2]
You may hear non-binary used as an umbrella term for various groups of people that don’t identify as male or female. 6. Intersex. A person born with either some combination of both biological ...
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.
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 ...
The pelvis is, in general, different between the human female and male skeleton. [12] [13] Although variations exist and there may be a degree of overlap between typically male or female traits, [12] [13] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex ...
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] Thus, male mammals typically have an X and a Y chromosome (XY), while female mammals typically have two X chromosomes (XX).
