10 Clinical Trials for Various Conditions
This study will explore the influence of social and environmental factors, such as stress, nutrition, health status, etc., on women's reproductive function. Married Mayan women 16-42 years of age who live in the rural highlands of Guatemala and who have given birth to at least one child are eligible to participate in this study. Participants are interviewed about their demographic, social, family, personal, health, reproductive and economic situations. They have saliva and urine samples collected three times a week for up to 1 year. Their nutritional and health status is assessed monthly.
The rapidity with which progesterone slows LH (and by inference GnRH) pulse frequency in women is unclear. The investigators hypothesize that progesterone slows LH pulse frequency within 10 hours. The investigators propose to assess this further with a randomized, cross-over, placebo-controlled study. Regularly cycling women without hyperandrogenism will be admitted to the Clinical Research Unit on cycle day 5-9 (mid-follicular phase) for a 10 hour frequent sampling study to observe LH, FSH, estradiol, progesterone, and testosterone. Either oral micronized progesterone suspension or placebo will be administered at 0900 h. During a subsequent menstrual cycle, subjects will undergo another study identical to the first except that oral progesterone will be exchanged for placebo or vice versa in accordance with a crossover design.
This study will determine the effect of medication for bipolar disorder on the reproductive function and whether mood changes occur during the menstrual cycle in women with bipolar disorder.
This study seeks to understand how frailty, a term that describes people who are more vulnerable stressors such as a new medical problem, affects the outcomes and quality of life in adult patients with gynecologic cancer.
This randomized pilot clinical trial studies the feasibility of a pre-operative and/or post-operative scripted sexual health informational intervention and how well it works in improving sexual function in patients with gynecologic cancer. Discussing sexual outcomes and counseling options with patients may help improve sexual outcomes and/or anxiety after primary gynecologic cancer treatment.
The study is seeking to understand how being overweight and obese makes women less fertile. The studies the investigators have done so far indicate that there is a hormone or other substance produced by fat that goes into the blood and reduces reproductive hormones in women who are overweight and obese. The present study will try to find the most promising substances by studying small numbers of women and trying to remove the substances that are causing the problem. Hypothesis: A circulating factor or factors, either hormonal, inflammatory or metabolic, causes relative pituitary hypofunction and correction of this reproductive deficit will allow obese women with infertility who have failed to reduce their body weight to normal to conceive, and may also prevent the horizontal passage of an adverse metabolic phenotype to the offspring.
One aim of this study is to determine changes in body composition and hormones that differentiate athletes who stop getting their periods versus those who continue to get their periods and non-athletes. The second aim of this study is to determine whether transdermal or oral estrogen (versus no estrogen) is effective in increasing bone density and improving bone microarchitecture in adolescent athletes who are not getting their periods and are thus estrogen deficient. The investigators hypothesize that transdermal estrogen will be more effective than oral estrogen or no estrogen in improving bone health in amenorrheic adolescent athletes.
The proposed study involves experimentally manipulating reproductive hormones in nonpregnant, euthymic women to create a scaled down version of the changes that occur during pregnancy and the postpartum period. This endocrine manipulation paradigm, which the investigators have shown provokes irritability in past studies, will be used to examine the neurocircuitry underlying irritability under baseline and hormone challenge conditions among women who are hormone sensitive (HS+; n=15) and non-hormone sensitive (HS-; n=15). The long-term goal of this research is to advance understanding of the neural systems underlying both the triggering of and susceptibility to irritability in women. The objective of the current project is to examine whether HS+ show differences in the behavioral activation system relative to HS- under baseline and hormone challenge conditions using functional magnetic resonance imaging (fMRI) and behavioral tests.
RATIONALE: Studying quality of life in breast cancer survivors may help determine the long-term effects of breast cancer and may help improve the quality of life for future breast cancer survivors. PURPOSE: This clinical trial is studying quality of life in female breast cancer survivors and their spouse, partner, or acquaintance.
Postmenarchal female cancer patients scheduled to undergo cancer therapy may enroll in this study to assess changes in existing and novel surrogate measures of fertility potential before, during and after chemotherapy. Measures of fertility potential to be tested include ultrasound imaging for antral follicle counts and ovarian volumes, endocrine evaluation, and assessment of oxidative stress.
