Gonadal Dysgenesis is an intersex bodily/corporeal variation of the atypical embryonic development of the gonads, with reproductive tissue replaced with dysfunctional, fibrous tissue, which is called streak gonads. Streak gonads are a form of aplasia, resulting in hormonal failure that manifests as sexual infantism and infertility, with no initiation of puberty and secondary sex characteristics.[1]
One with this variation cannot ovulate as their reproductive tissue is not formed and is instead replaced with simple tissue. This is usually seen with people who have 45,X/46,XY Mosaicism or Turners syndrome, however it can be a variation amongst itself.
This variation may also cause one to fall under the secondary sex agenesis spectrum.
Swyer Syndrome
Swyer Syndrome is a form of Gonadal Dysgenesis. It is typically affecting an AFAB otherwise or CTF individual with müllerian genitals and a müllerian reproductive system, that have their functionless gonads that are replaced with streak gonads. If left without HRT, they will not experience puberty.[2] This often causes one to also have AFAB Hypogonadism.
The name was chosen to be named after the endocrinologist who first discovered it, Gerald Swyer.[3]
History
Swyer syndrome was first described by G. I. M. Swyer in 1955 in a report of two cases.[3]
