Superovulation of habitual aborters with subtle luteal phase deficiency.
Five habitual aborters without a known organic cause of their pregnancy losses were studied in detail by serial blood sampling for immunoreactive estrogen, progesterone, follicle-stimulating hormone, luteinizing hormone, and the ratio of the two. All patients had premenstrual spotting regularly. Luteal phase progesterone levels on the 6th postovulatory day were significantly lower (11.8 +/- 1.2 ng/mL, mean +/- SEM) than in control patients (20.8 +/- 3.5 ng/mL, mean +/- SEM). Results of immunoreactive estrogen, FSH, and LH assays and the FSH/LH ratio did not reveal a discernible pattern of deviation from normal. Indirect immunofluorescence of blood samples from all habitual aborters showed evidence of autoimmunity in three of five patients without clinical symptoms of autoimmune disease. Treatment by superovulation produced at least one living child in each couple. The balance of pregnancy outcome changed from 100% abortion (N = 31) before treatment to 31% (N = 13) after treatment. These results suggest that treatment with superovulation may be the treatment of choice for habitual aborters with a subtle luteal phase deficiency.
