Pregnancy in a woman with Turner mosaicism following ovarian stimulation and in vitro fertilization.

We conclude that women with Turner mosaicism (46XX/45XO) and normal FSH levels may have an adequate ovarian reserve and undergo attempts at traditional assisted reproduction. At the time of retrieval an ovarian biopsy may be performed in order to evaluate directly the ovarian karyotype. A successful pregnancy resulted from oocytes retrieved from the gonad demonstrating a normal karyotype.
