Main outcome measures Age at diagnosis, risk of gonadal malignancy, bone mineral density, uterine size. absent uterus. Sexual development is usually determined by an individual's chromosomes; however, in Swyer syndrome, sexual development does not match the affected individual's chromosomal makeup. A patient with a 46,XY chromosome constitution showed the following main characteristics: eunuchoidal body habitus, lack of secondary sexual development, normal female external genitalia with absence of vagina, no gonadal structures, and complete lack of internal genitalia except for rudimentary ductal structures defined by histological examination. Swyer syndrome is a disorder where sex glands - ovaries or testes - fail to develop normally. Even more surprising, however, is the fact that the average age of girls being diagnosed with gonadal dysgenesis, previously known as Swyer syndrome, is 17 years." The reason for this high age at diagnosis is presumably that these women actually develop sexual organs that are almost normal.

Swyer syndrome (XY gonadal dysgenesis, XY female) Swyer syndrome is a condition affecting the sexual development of a chromosomally male foetus, resulting in a female child. Her condition is clearly different from that . Two of the 46 chromosomes, known as X and Y, are called . leads to no ovarian stimulation and no estradiol production. The lack of appearance of secondary sex characteristics in females and males by the age of 13 and 14, respectively, is described as delayed puberty.1 In 1955, Swyer first described two phenotypic women with gonadal dysgenesis without the stigma of Turner syndrome (46 XY pure gonadal dysgenesis, now known as Swyer syn- drome).1,2 The chance of .

Her parents were young, healthy and unrelated and there are no cases of genetic syndromes in the It is characterized by the failed development of the sex glands (i.e. This condition is due to a mutation which inhibits the function of the Y-borne determinant that would normally cause the indifferent embryonic gonad to differentiate into a testis. They typically have normal female external genitalia, and are female. Swyer's syndrome is a form of pure gonadal dysgenesis. A person with this disorder is typically raised as a female due to the normal appearance of female genitalia and the presence of a uterus and fallopian tubes. Sex development usually follows a particular path based on an individual's chromosomes; however, in Swyer syndrome, sex development is not typical for the affected individual's chromosomal pattern. Swyer syndrome is a disorder of sex development caused by a defect in the SRY gene on chromosome Y. It takes certain hormonal changes to make a fetus male. characteristics. The presentation of Swyer syndrome is that of a tall female with a normal childhood and . testicles or ovaries ). MacLeod's syndrome (Swyer-James' syndrome in the child) is a radiologic entity: hyperlucency of one or several lobes, or even of one lung, scarce hilar shadow on the same side as the abnormal transradiency, and barely visible arterial network on the abnormal side of the thorax. There are many forms of gonadal dysgenesis. 2 I think we need an article on gonadal dysgenesis.

In most individuals with Swyer syndrome, the cause is unknown. Swyer syndrome, turner syndrome and PURE GD. Swyer syndrome is a genetic condition affecting sexual organ development, classified as a disorder of sex development (DSD). The diagnosis of Swyer syndrome was made in our case because she was a normal-statured girl with primary amenorrhea with clinical features of sexual infantilism whose genotype was pure XY and the gonadal tissues are fibrous band [Figure 2].
