  • Title: Suppression of gonadotrophin secretion does not reverse premature ovarian failure.

    Abstract:
    The effect of prolonged inhibition of gonadotrophin secretion was studied in 12 women with premature ovarian failure. All the patients had plasma concentrations of follicle-stimulating hormone (FSH) greater than 20 i.u./l, and in six, primordial follicles had been seen on ovarian biopsy. Goserelin (Zoladex, ICI), a depot synthetic analogue of luteinizing hormone-releasing hormone (LHRH) was administered by three consecutive 4-weekly injections. Plasma concentrations of luteinizing hormone (LH) fell from 34 (SD 11) i.u./l to 2.4 (SD 1.9) i.u./l, and plasma concentrations of FSH fell from 106 (SD 29) i.u./l to 4.5 (SD 2.6) i.u./l 4 weeks after the first injection. Plasma concentrations of gonadotrophins returned to pretreatment values in every patient within 9 weeks of the final injection of goserelin. Regular ultrasonography during the period following the final injection failed to demonstrate the development of ovarian follicles in any patient, and plasma concentrations of oestradiol remained below 100 pmol/l. This study has failed to show that suppression of gonadotrophin secretion reverses premature ovarian failure.
