Ovarian failure is a typical feature in Turner's syndrome. The majority of follicles disappears prematurely after a normal determination of the ovary. This results from an accelerated loss of oocytes from the ovaries after the 18th week of fetal life or over a few postnatal years, usually before the onset of puberty. The cause and mechanism of this loss are unknown. X chromosomal anomaly due to deletions or haploinsufficiency of genes can explain the various degrees of ovarian failure. Spontaneous puberty occurs in 20-30% of Turner syndrome patients and their fertility rates vary from 5 to 10%. This indicates the possible presence and maturation of follicles in their ovaries in adolescence. In ovarian failure, the hormone replacement therapy (HRT) is necessary to achieve the development of normal female sexual characteristics, the self image or social functioning and to prevent osteoporosis. Pregnancy is now possible with oocyte donation. A careful cardiovascular follow-up is necessary. Cryoconservation represents one way for preserving the future fertility, but the optimal age of ovarian biopsy has to be studied.
