Spontaneous pregnancy in women with Turner syndrome is rare (5%) and relatively high risk. A number of methods to preserve fertility in such women have been discussed. Careful follow-up is required during these pregnancies due to the high incidence rates of neonatal, obstetric, maternal, and cardiovascular complications. A 39-year-old multigravid woman (G5, P3, A2) with mosaic Turner syndrome with a history of three spontaneous pregnancies and two miscarriages was evaluated at our clinic. The analysis showed mos 45,X /46,XX  mosaic Turner syndrome. Her first and fourth pregnancies resulted in miscarriages during the first trimester. Here, we discuss a pregnant woman with mosaic Turner syndrome with unaffected fertility but with a history of spontaneous pregnancies/miscarriages, with reference to the current literature.Keywords: Mosaic turner syndrome, spontaneous pregnancy, turner syndrome.
