Premature ovarian failure-21 (POF21) is characterized by female infertility due to primary or secondary amenorrhea. Ovaries are small, atrophic, or nonvisualized on ultrasound (Tucker et al., 2019; Tucker et al., 2022).
For a general phenotypic description and a discussion of genetic heterogeneity of POF, see POF1 (311360). [from
