Comparative study of assisted reproductive outcomes between young patients with occult premature ovarian insufficiency and advanced-age patients.

ObjectiveThe purpose of this study was to compare the pregnancy outcomes among young patients with occult premature ovarian insufficiency (OPOI), advanced-age patients with diminished ovarian reserve (DOR), and advanced-age patients with normal ovarian reserve.MethodsWe retrospectively reviewed 324 women who underwent their first cycles of in vitro fertilization/intracytoplasmic sperm injection. The women were divided into the following groups: young women with OPOI, advanced-age women with DOR, and advanced-age women with normal ovarian reserve. The outcomes were compared among the different groups.ResultsThe rates of live birth and embryo implantation in the young OPOI group were significantly higher than in the advanced-age DOR group, but comparable to those in the advanced-age normal ovarian reserve group. Moreover, the abortion rate was significantly lower in young OPOI patients compared with advanced-age patients with or without DOR.ConclusionHigher embryo implantation and live birth rates and a lower abortion rate can be achieved in young patients with OPOI compared with older patients. The better outcomes in advanced-age patients with normal ovarian reserve compared with DOR may be related to egg quantity rather than quality.
