Yes, people with Swyer syndrome have ovaries. Swyer syndrome, also known as 46,XY gonadal dysgenesis, is a condition in which individuals are born with the genetic makeup of a male (46,XY) but have no detectable levels of male hormones and female external organs. These individuals typically have a female phenotype (appearance) but do not have ovaries or other female reproductive organs.
However, in some cases, people with Swyer syndrome have been found to have non-functioning ovaries. This is due to the fact that, even though the individual has a 46,XY genetic makeup, the gonads, or reproductive organs, may develop as ovaries instead of testes. The ovaries, however, are not functional and do not produce hormones or eggs.
In addition, some individuals with Swyer syndrome may have a form of the disorder called Partial Gonadal Dysgenesis, which is characterized by the presence of both testicular and ovarian tissue in the same gonad. In this case, the ovarian tissue does not produce eggs, and the testicular tissue does not produce sperm.
Overall, individuals with Swyer syndrome can have ovaries, but they are typically non-functional. People with this condition require hormone therapy and careful medical monitoring in order to ensure they remain healthy.
