Abstract

CONTEXT: Many girls with Turner syndrome have follicles in their ovaries at adolescence. OBJECTIVE: Our objective was to study which girls might benefit from ovarian tissue freezing for fertility preservation. DESIGN: Clinical and laboratory parameters and ovarian follicle counts were analyzed among girls referred by 25 pediatric endocrinologists. SUBJECTS AND SETTING: Fifty-seven girls with Turner syndrome, aged 8-19.8 yr, were studied at a university hospital. INTERVENTIONS: Ovarian tissue was biopsied laparoscopically, studied for the presence of follicles, and cryopreserved. Blood samples were drawn for hormone measurements. MAIN OUTCOME MEASURES: Presence of follicles in the biopsied tissue related to age, signs of spontaneous puberty, karyotype, and serum concentrations of gonadotropins and anti-Müllerian hormone were assessed. RESULTS: Ovarian biopsy was feasible in 47 of the 57 girls. In 15 of the 57 girls (26%), there were follicles in the tissue piece analyzed histologically. Six of seven girls (86%) with mosaicism, six of 22 (27%) with structural chromosomal abnormalities, and three of 28 with karyotype 45X (10.7%) had follicles. Eight of the 13 girls (62%) with spontaneous menarche had follicles, and 11 of the 19 girls (58%) who had signs of spontaneous puberty had follicles. The age group 12-16 yr had the highest proportion of girls with follicles. Normal FSH and anti-Müllerian hormone concentrations for age and pubertal stage were more frequent in girls with follicles. CONCLUSIONS: Signs of spontaneous puberty, mosaicism, and normal hormone concentrations were positive and statistically significant but not exclusive prognostic factors as regards finding follicles.

  • More than one third of girls with Turner syndrome develop signs of puberty; in non-45,X patients this is twice as common.

    “More than one third of girls with TS develop signs of puberty, in non-45,X patients this is twice as common.”
  • The chance for spontaneous pregnancy in Turner syndrome is about 10%, and it is more common in women with mosaic karyotype.

    “the chance for spontaneous pregnancy is about 10%, again more common in women with mosaic karyotype.”
  • Only one in five girls with Turner syndrome has spontaneous menarche.

    “Only one in five girls has spontaneous menarche”
  • Findings associated with an increased likelihood of identifying follicles in the ovarian cortex include mosaic karyotype with a 46,XX cell line, spontaneous puberty, measurable AMH, or FSH <10 IU/L.

    “Findings that may be associated with an increased likelihood of identifying follicles in the ovarian cortex include (1) mosaic karyotype with a 46,XX cell line, (2) spontaneous puberty, (3) measurable AMH or (4) FSH <10 IU L−1.263,578,579”
  • In individuals with TS, AMH is associated with clinical features of ovarian reserve and has the strongest positive correlation with the presence of follicles in ovarian cortex tissue.

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.
