Abstract

Background: Turner syndrome (TS) is accompanied with premature ovarian insufficiency. Oocyte vitrification is an established method to preserve fertility. However, data on the oocyte yield in women with TS who vitrify their oocytes and the return rate to utilize the oocytes are scarce. Methods: Retrospective multicenter cohort study. Data was collected from medical records of women with TS who started oocyte vitrification between 2010 and 2021. Results: Thirty-three women were included. The median cumulative number of vitrified oocytes was 20 per woman. Complications occurred in 4% of the cycles. Significant correlations were found between the cumulative number of vitrified oocytes and AMH (r = 0.54 and p < 0.01), AFC (r = 0.49 and p < 0.01), percentage of 46,XX cells (r = 0.49 and p < 0.01), and FSH (r = −0.65 and p < 0.01). Spontaneous (n = 8) and IVF (n = 2) pregnancies occurred in 10 women ± three years after vitrification. So far, none of the women have returned to utilize their vitrified oocytes. Conclusions: Oocyte vitrification is a feasible fertility preservation option for women with TS, particularly in those with 46,XX cell lines or sufficient ovarian reserve. Multiple stimulation cycles are recommended to reach an adequate number of vitrified oocytes for pregnancy. It is too early to draw conclusions about the utilization of vitrified oocytes in women with TS.

  • Accurate characterization of even low-level chromosomal mosaicism by assessing two cell lines (lymphocytes and buccal cells) may help to more precisely estimate fertility potential.

  • The optimal number of oocytes required for a successful live birth in TS is still unknown.

    “Therefore, care should be taken in counselling individuals with TS and their families as the optimal number of oocytes required for a successful live birth is still unknown.578”
  • In the largest retrospective study to date, Nadesapillai et al. reported that the percentage of 46,XX cells, FSH, AMH, and antral follicle count had a significant correlation with the cumulative number of vitrified oocytes.

    “In one retrospective study Martel at al. found that age, karyotype and FSH had no correlation with the number of vitrified oocytes,599 while in the largest retrospective study to date Nadesapillai et al. reported that the percentage of 46, XX cells, FSH, AMH and antral follicle count had a significant correlation with the cumulative number of vitrified oocytes.578”
  • Published data regarding oocyte cryopreservation in individuals with TS entails six retrospective studies and eight case reports comprising a total of 80 individuals ranging in age from 7 to 30 years.

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.
