Sumario:Swyer syndrome is a hereditary condition seen in a few patients who present with primary amenorrhea, characterized by 46 XY and the presence of female internal genital tract and bilateral streak gonads in a female phenotype. A 25-year-old lady presented with primary amenorrhea. After the evaluation, she was diagnosed with Swyer syndrome due to a mutation in the SRY gene, leading to failure of testicular development. The clinical presentation was that of a female phenotype with no secondary sexual characteristics. On physical examination, she had a female phenotype with a short vagina and no secondary sexual characteristics. The MRI revealed a hypoplastic uterus with both fallopian tubes but with streak gonads. The patient's genotype was found to be 46 XY after genetic testing. The streak gonads were removed laparoscopically due to the future risk of gonadoblastoma, and the patient was given hormone replacement therapy (HRT). The patient started menstruating after six months of HRT and has been developing secondary sexual characteristics (Tanner stage II) till now.
