Journal ArticleDOI
Prospective Study of Sex Hormone Levels and Risk of Prostate Cancer
TL;DR: High levels of circulating testosterone and low levels of SHBG-both within normal endogenous ranges-are associated with increased risks of prostate cancer, and circulating levels of DHT and AAG do not appear to be strongly related to prostate cancer risk.
Journal ArticleDOI
Alcohol, Height, and Adiposity in Relation to Estrogen and Prolactin Levels in Postmenopausal Women
Susan E. Hankinson,Walter C. Willett,JoAnn E. Manson,David J. Hunter,Graham A. Colditz,Meir J. Stampfer,Christopher Longcope,Frank E. Speizer +7 more
TL;DR: BMI and alcohol use were positively associated with postmenopausal plasma estrogen and estrone sulfate levels, respectively and additional studies are needed to further quantify the relationship between alcohol consumption and plasma hormone levels and to elucidate the physiologic basis for this association.
Journal ArticleDOI
Effects of Alcohol Consumption on Plasma and Urinary Hormone Concentrations in Premenopausal Women
Marsha E. Reichman,Joseph T. Judd,Christopher Longcope,Arthur Schatzkin,Beverly A. Clevidence,Padmanabhan P. Nair,William S. Campbell,Philip R. Taylor +7 more
TL;DR: This study has shown increases in total estrogen levels and amount of bioavailable estrogens in association with alcohol consumption in premenopausal women, and increased total estradiol levels in the peri-ovulatory phase suggest elevated absolute amounts of bio available estradio.
Journal Article
Reproducibility of plasma hormone levels in postmenopausal women over a 2-3-year period.
Susan E. Hankinson,JoAnn E. Manson,Donna Spiegelman,Walter C. Willett,Christopher Longcope,Frank E. Speizer +5 more
TL;DR: Data indicate that, for most of these plasma hormones, a single measurement can reliably categorize average levels over at least a 3-year period in postmenopausal women.
Journal ArticleDOI
Steroid and gonadotropin levels in women during the peri-menopausal years
TL;DR: There were significant correlations between FSH concentrations and the concentrations of E1, E2 and E1SO4 for women who were less than 3 mth from a menses as well as those whose last menses had occurred 3 or more mth previously and the correlations were generally not significant for LH in either groups of women.
