Estrogen loss after natural menopause is hypothesized to impair episodic memory. A total of 326 women aged 52 to 63 years participating in the Melbourne Women's Midlife Health Project completed a word list memory task. Estrogen exposures were inferred from menopausal status, time from final menstrual period, use of hormone therapy, serum estradiol(More)
BACKGROUND The reproductive hormone inhibin has been used as a diagnostic marker of ovarian mucinous and granulosa cell cancers. The aims of this study were to develop a new inhibin immunofluorometric assay (alphaC IFMA) to replace an inhibin RIA as a diagnostic marker of these ovarian cancers and to assess whether the alphaC IFMA in combination with CA125,(More)
The factors involved in the pathogenesis of ovarian cancers remain unclear, and the response of these tumors to hormonal therapy is limited. The identification of a second estrogen receptor gene (ERbeta), expressed predominantly in ovarian granulosa cells, led us to explore its possible role in ovarian cancer, particularly in granulosa cell tumors (GCT).(More)
OBJECTIVE To determine whether multiple ovulation in mothers of spontaneous dizygotic (DZ) twins is because of higher hypothalamic stimulation or is in response to lower serum levels of ovarian inhibin. DESIGN Serum hormone levels were measured at five times throughout the cycle in a sample of eight mothers of DZ twins and paired controls. On day 12,(More)
OBJECTIVE Across a woman's lifetime, variations in hormone levels are known to influence mood and well-being. Whether absolute or changes in hormone levels over time are associated with depression among postmenopausal women remains unclear. METHODS The Melbourne Women's Midlife Health Project is a longitudinal population-based study of women who were(More)
Dizygotic twinning is familial, suggesting that there may be an inherited abnormality of the control of ovulation that predisposes to double ovulation and, therefore, dizygotic twins. The present study examines 17 mothers of dizygotic twins (MODZT) and 8 control mothers of singletons by daily blood sampling throughout an entire menstrual cycle. Blood(More)
The molecular pathogenesis of granulosa cell tumors of the ovary is not understood, although recent studies have shown that immunoreactive inhibin secretion by these tumors may be used as a tumor marker. Granulosa cell tumors exhibit many features of normal granulosa cells, including a response to FSH and inhibin secretion. FSH levels are suppressed in(More)
In a previous study (see Ref.7), the molecular weight distribution of inhibin activity in fractionated human follicular fluid (hFF) and human male and female plasma/serum was determined by in vitro bioassay using ovine pituitary cells in culture and various specific inhibin A and inhibin alpha-subunit-directed immunoassays. It was shown, however, that the(More)
Human plasma inhibin was measured by radioimmunoassay in 26 women undergoing ovarian hyperstimulation for in-vitro fertilisation. Plasma inhibin rose in parallel with oestradiol during gonadotropin therapy (r = 0.79, p less than 0.001). Peak plasma inhibin levels correlated with follicle number as determined by ultrasonography (p less than 0.001) and with(More)
Sexual problems are often reported to clinicians by women in the midlife years. Yet few of the epidemiological studies of women in midlife have investigated the relationship of the menopause to sexual functioning. This paper reports the results of a cross-sectional telephone survey of 2001 randomly selected Australian-born women aged between 45 and 55(More)
