[3][4] Women with Turner syndrome whose karyotype includes a Y chromosome (as in 45,X/46,XY mosaicism) are at increased risk for gonadoblastoma.
In a population-based study, the cumulative risk for women with Turner syndrome and Y chromosome material was 7.9 percent by age 25 years.
[5] Gonadoblastomas can contain elements of both germ cells and gonadal stroma.
If the diagnosis of gonadoblastoma is certain, a bilateral salpingo-oophorectomy (BSO) should be performed to remove both the primary tumor and the dysgenic contralateral ovary.
Modern reproductive endocrinology technology allows patients post BSO to achieve pregnancy via in-vitro fertilization (IVF) with a donor egg.
