Fertility and pregnancy outcome in Danish women with Turner syndrome

Abstract

The aim of the investigation was to study fertility in Danish women diagnosed with Turner syndrome (TS), and to describe their offspring. In total, 410 women in the fertile age were registered in the Danish Cytogenetic Central Register with TS between January 1973 and December 1993. Their karyotype were as follows: 49% with 45,X, 23% with mosaicism and a structural abnormality of the second X, 19% with 45,X/46,XX mosaicism, and 9% with 46,XX and a structural abnormality of the second X. Thirty-three women, one with 45,X, 27 with mosaicism and 5 with 46,XX and a structural abnormality of the second X, gave birth to 64 children. Two women had become pregnant after in vitro fertilization, including a woman with 45,X after an egg donation. Thus, 31 women(7.6%) had achieved at least one spontaneous pregnancy, but 48% of the fertile women registered with 45,X/46,XX had 45,X in less than 10% of the analysed cells. Twenty-five of the 64 children had a chromosome analyzed. Six of the 25 examined children, including three siblings, had chromosomal aberrations. No case of Down's syndrome was present, and only two children had malformations. Fertility in women registered with TS is higher than earlier reported. However, only women with 45,X/46,XX mosaicism or 46,XX and structural abnormality of the second X, gave birth to live children after spontaneous pregnancies.

  • Due to ovarian insufficiency, most individuals with TS are infertile, with spontaneous pregnancies occurring in about 10%.

  • The key predictive factors associated with the probability of spontaneous conception are a history of spontaneous menarche and a 45,X/46,XX karyotype.

  • Data are inconsistent regarding the risk of birth anomalies, which are reported in 0%-24% of spontaneous TS pregnancies compared with ∼3% in the background population.

  • Reported anomalies in TS pregnancies include cerebral palsy, neuropsychological disorders, cleft lip and palate, coarctation of the aorta, ambiguous genitalia, hydrocephalus, and trisomy 21.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
