Objective: To study the relation between plasma gonadotropin pulsatility, androgen levels, and estrogen levels in patients with polycystic ovary syndrome (PCOS), in hirsute women with normal menstrual cycles, and in healthy women.
Design: Prospective study.
Setting: University medical center-based cellular and molecular endocrinology laboratory.
This study explored the effect of the anti-androgen spironolactone on sex-hormone binding globulin (SHBG) and the distribution of circulating testosterone (T) into various free and bound fractions in seven women with hirsutism assessed before and then monthly for three months on a regimen of spironolactone, 100 mg bid as the sole therapeutic agent. Blood samples were taken at each assessment time for a battery of androgen parameters and serum T fractions studies. None of the women were judged obese based upon body mass index values.

We examined the effect of a long-acting preparation of GnRHa in biodegradable microcapsules. D-Tryptophane6-GnRH, administered intramuscularly at 1 month intervals, for 12 consecutive months, on growth and skeletal maturation in 3 girls and 4 boys with neurogenic or idiopathic precocious puberty.

All of them were submitted to two tests: TRH stimulation and after the administration of dopamine receptor-blocking drug, Domperidone. The hypothyroid patients with basal TSH values less than or equal to 60 mU/L (4 cases--group 1) had lower PRL levels than the remaining 4 subjects with TSH greater than 60 mU/L (group 2) (p less than 0.
