A New Cause of Female Pseudohermaphroditism: Placental Aromatase Deficiency

Abstract

A description is presented of the first documented case of placental aromatase deficiency. The deficiency caused maternal virilization during pregnancy and pseudohermaphroditism of the female fetus. A 24-yr-old primigravida showed progressive virilization during the third trimester. Urinary excretion of estrogen was less than 14 mumol/day between 35-38 weeks of pregnancy, although nonstress tests showed reactive patterns and serum levels of human placental lactogen were above 460 nmol/L. Maternal serum levels of estrogens were low, and those of androgens were high in the third trimester. A dehydroepiandrosterone sulfate loading test induced a marked increase in maternal serum levels of androgens, whereas no such increase was observed in estrogens. The woman delivered vaginally a live full-term infant who exhibited female pseudohermaphroditism. Cord serum levels of estrogens were extremely low, while those of androgens were high. The aromatase activity of the placenta, determined by the conversion of [7-3H]androstenedione to 17 beta-[7-3H]estradiol and [7-3H]estrone, were less than 0.03 fmol/microgram protein.min (control, 9.6 +/- 2.2 fmol/microgram protein.min). The sulfatase activity of the placenta was 0.63 pmol/microgram protein.min compared to 0.46 +/- 0.16 pmol/microgram protein.min in controls. The rate of aromatization by normal control placentas was the same as that obtained during coincubation of samples of normal placentas and that of the patient. Thus, the presence of aromatase inhibitor in the patient's placenta was excluded.

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.
