Filter by:This project is examining the reproductive effects of exposure to certain compounds that are suspected to act on the endocrine system, e.g. they may act like or interfere with hormones such as estrogen. The study is being conducted among Laotian women, as it is suspected that they may have higher exposures to the compounds of interest (pesticides and PCBs) from their homeland and from consumption of fish caught in the San Francisco Bay. Fifty Laotian immigrants were recruited by community workers to collect urine daily during 3 menstrual cycles for measurement of steroid hormones (estrogen and progesterone). Additionally, they provided a blood sample to measure exposure levels, and completed 2 interviews in their native language. These measured levels, as well as the self-reported data on a number of factors including fish consumption, will be examined for possible effects on hormone levels and menstrual function.
No proven therapy to restore ovarian function and fertility is available to patients with karyotypically normal spontaneous premature ovarian failure. We know that one-half of these patients have primordial follicles remaining in the ovary, and these follicles can function intermittently. This is a diagnostic omnibus protocol that permits baseline clinical evaluation of patients with prematurem ovarian failure. The findings will determine patients' suitability for specifically focused therapeutic research protocols.
