The effect of short term administration of flutamide on the hypothalamic-pituitary-gonadal axis was studied in six patients with advanced prostate cancer (C2 stage). Flutamide significantly increased LH pulse frequency in all patients (p less than 0.05 by Wilcoxon's test). The FSH pulse analysis disclosed a similar pattern of LH. Plasma IC-T clearly increased following flutamide therapy; mean IC-T values were 2.67 +/- 0.47 ng./ml. and 4.67 +/- 0.62 ng./ml. before and after flutamide administration, respectively (p less than 0.05 by paired Student's t test). Our study demonstrates that flutamide acts in humans as a selective and specific antiandrogen compound.

D007030 Hypothalamo-Hypophyseal System A collection of NEURONS, tracts of NERVE FIBERS, endocrine tissue, and blood vessels in the HYPOTHALAMUS and the PITUITARY GLAND. This hypothalamo-hypophyseal portal circulation provides the mechanism for hypothalamic neuroendocrine (HYPOTHALAMIC HORMONES) regulation of pituitary function and the release of various PITUITARY HORMONES into the systemic circulation to maintain HOMEOSTASIS.

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.

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.
