OBJECTIVE The variable hypogonadism in Prader-Willi syndrome (PWS) has generally been attributed to hypothalamic dysfunction. Recent studies have documented primary testicular dysfunction in PWS males. Our aims were to characterize sexual development and reproductive hormones in PWS females and to investigate the etiology of hypogonadism. DESIGN A(More)
BACKGROUND/AIMS To investigate the etiology of hypogonadism in women with Prader-Willi Syndrome (PWS). METHODS Ten women aged 23 +/- 5.5 years with PWS and 10 age- and BMI-matched controls were included. Blood samples were drawn and abdominal ultrasounds were performed on days 2-4 of spontaneous cycles or at random from amenorrheic women. Anti-Mullerian(More)
BACKGROUND Recent studies challenge the assumption that hypogonadism in Prader-Willi syndrome (PWS) is due only to hypothalamic dysfunction. OBJECTIVES The aims of the study were to characterize sexual development and reproductive hormones in PWS males and investigate the etiology of hypogonadism. METHODS Physical examination and blood sampling were(More)
A comparison was made between the toxic effects of chronic chlorpromazine, haloperidol or atropine on the guinea pig intestinal tract. Chlorpromazine, administered at a dose of 30 mg/kg/day, IP for 7 days, produced marked pathologic changes in the guinea pig cecum, consisting of inflammation, edema and hemorrhage. None of these effects were noted when(More)
BACKGROUND Hypogonadism is a major feature of Prader-Willi syndrome (PWS), but clinical manifestations are variable. Sexual interests and behavior in this population have not been previously described. OBJECTIVES We studied PWS adolescents and young adults to assess 1) satisfaction with physical and sexual development, 2) frequency of romantic and sexual(More)
