Reassessing fecundity in women with classical congenital adrenal hyperplasia (CAH): normal pregnancy rate but reduced fertility rate

Abstract

Summary: Objective Fertility in women with classical congenital adrenal hyperplasia (CAH) has been reported low; however, the true pregnancy rate for women trying to conceive with this condition is unknown. Our aim was to calculate pregnancy rate for women with CAH calculated as a proportion of those who had attempted conception. Fertility expressed as live birth rate is also calculated. Patients One hundred and six women with classical CAH followed in a multidisciplinary service [81 salt‐losing (SL) and 25 nonsalt‐losing (NSL) form]. Results Twenty‐five (23·6%) women with CAH women considered motherhood, 23 had actively tried conception of whom 21 (91·3%) achieved 34 pregnancies. Pregnancy rate is no different from that in the normal population (95%). Pregnancy rates were similar in the SL (88·9%) and NSL (92·9%) subgroups but those with NSL‐CAH were more likely to seek motherhood than those with SL‐CAH (16/25 vs. 9/81). Optimized glucocorticoid and mineralocorticoid regimes during fertility monitoring resulted spontaneous conception in nearly all recent cases. Fertility rate was 0·25 live births per woman compared with 1·8 in the UK population ( P < 0·001). Conclusion We report a normal pregnancy rate (91·3%) for women with classical CAH, similar in SL and NSL subgroups. Fertility rate, however, remains much lower than in general population.

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.
