Spontaneous gonadotrophin pulsatility and ovarian morphology in girls with central precocious puberty treated with cyproterone acetate. 1985

R Stanhope, and P J Pringle, and J Adams, and S L Jeffcoate, and C G Brook

We have studied four girls with central precocious puberty treated with cyproterone acetate for a mean of 3.6 years (range 1.5-6.3 years). Pelvic ultrasound assessment demonstrated suppression of the ovarian morphology of central precocious puberty despite the presence of spontaneous pulsatile gonadotrophin secretion at night. We suggest that the previously reported effects on gonadotrophin secretion induced by cyproterone acetate therapy, administered in recommended doses, are minor and that the predominant effect of cyproterone acetate in the treatment of girls with central precocious puberty is direct inhibition of ovarian steroidogenesis.

UI MeSH Term Description Entries
D007223 Infant A child between 1 and 23 months of age. Infants
D007986 Luteinizing Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

D010053 Ovary The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE. Ovaries
D011629 Puberty, Precocious Development of SEXUAL MATURATION in boys and girls at a chronological age that is 2.5 standard deviations below the mean age at onset of PUBERTY in the population. This early maturation of the hypothalamic-pituitary-gonadal axis results in sexual precocity, elevated serum levels of GONADOTROPINS and GONADAL STEROID HORMONES such as ESTRADIOL and TESTOSTERONE.

D002648 Child A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL. Children

D003534 Cyproterone An anti-androgen that, in the form of its acetate (CYPROTERONE ACETATE), also has progestational properties. It is used in the treatment of hypersexuality in males, as a palliative in prostatic carcinoma, and, in combination with estrogen, for the therapy of severe acne and hirsutism in females. Cyproterone, 1alpha,2 alpha,9 beta,10 alpha-Isomer
D005260 Female Females
D005640 Follicle Stimulating Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.
