Effect of Exercise and Phytoestrogen on Bone, Metabolic Syndrome Criteria and Complaints of the...

Bone DiseasesMetabolic Syndrome X1 more

The aim of the study is to compare the effect of a progressive, periodized exercise training designed to impact bone, CHD-risk-factors and menopausal complaints versus the combined effect of exercise and "phytoestrogen" (cimicifuga racemosa; CR). After randomization, 84 females 1-3 year postmenopausal with no medication or illness affecting bone metabolism exercise over 12 months (EG; 42 with, 42 without CR), 42 women serve as wellness-control. Three group training sessions/week will be performed in the EG. Both groups will be individually supplemented with calcium and Vit-D (cholecalciferol).

Estrogen Dosing in Turner Syndrome: Pharmacology and Metabolism

Turner SyndromeHypogonadism1 more

Estrogen is necessary for feminization during puberty and to decrease bone resorption, the latter critical for the achievement of peak bone mass and normal bone health in the female. The practicing pediatric endocrinologist often faces the dilemma of how to best feminize girls with hypogonadism (lack of estrogen), manifested as delayed or arrested puberty, due to disorders of the brain or the ovaries. We propose a series of studies to address which type, dose, and route of delivery of estrogen are suitable choices in feminizing and sustaining estrogen concentrations in adolescent girls with Turner syndrome. To accomplish this we will study girls/young woman between the ages of 13 to 20 with Turner Syndrome in 2 protocols. In Protocol # 1 we will study 24 girls with TS, they will receive 3 different estrogen preparations, either by mouth or via a patch for a total of 6 weeks. They will come to the clinical research center for blood draws after 2 wks of taking the estrogen. With this study, we hope to learn how the body responds to estrogen differently, depending on the form estrogen is given and how high, estrogen levels gets in the blood in these girls with Turner Syndrome. We will be comparing these patients estrogen levels to girls that menstruate normally and do not have Turner Syndrome. In Protocol #2, 40 patients with TS will be recruited; these patients will take estrogen for 1 year, either by mouth or via a patch. Patients will come to the lab for blood drawn in 7 occasions and we will measure estrogen levels as well as other hormones and lipid levels. We will also perform a Dual-energy X-ray absorptiometry (DXA) study (like an X ray) to assess body composition and bone mineralization. We will adjust doses based on the estrogen levels we find. With this study we hope to learn how estrogen affects body composition, i.e., the amount of fat vs. muscle, and how different forms of estrogen affect blood cholesterol and other hormones. This study will allow us to understand better how to best replace young woman with Turner Syndrome with estrogen.

Is There A Role For Mechanical Stimulation In Ovarian Follicular Activation?

InfertilityFemale2 more

Premature ovarian failure (POI) is a loss of normal function before age 40, leading to infertility and hypoestrogenism. About 1% of women younger than 40 years old and 0.1% before 30 are affected. Most patients already had impaired or complete loss of fecundity when diagnosed. Hence, the treatment of POI is particularly tough. Currently, no optimal regimen exists to ameliorate ovarian function.

Hormone Replacement in Young Women With Premature Ovarian Failure

HealthyOsteoporosis1 more

The human ovary produces male sex hormones (androgen) and female sex hormones (estrogen). Currently, androgen is not included in hormone replacement therapy for women with premature ovarian failure. Present hormone replacement therapy (HRT) was designed to treat women who experience ovarian failure at menopause (around the age of 50). However, 1% of women will experience premature failure of the ovaries before the age of 40. There have been no studies conducted to determine proper hormone replacement therapies for these younger women. Some research suggests that the usual menopausal hormone replacement therapy is not adequate to protect young women with premature ovarian failure from developing osteoporosis. Women with premature ovarian failure have abnormally low levels of androgens circulating in their blood. This may contribute to the increase risk for osteoporosis. This study will compare two treatment plans for women with premature ovarian failure. Treatment plan one will be physiological estrogen hormone replacement. Treatment plan two will be physiological estrogen hormone replacement plus androgen. The study will attempt to determine which plan is more beneficial to women in relation to osteoporosis and heart disease. The hormones will be contained in patches and given by placing the patches against the patient's skin. The patches were designed to deliver the same amount of hormone as would be normally produced by the ovary in young women. The success of the treatment will be measured by periodically checking the density of patient's bone in the leg (femoral neck bone) . Researchers will take an initial (baseline) measurement of bone density before beginning treatment and then once a year, for 3 additional years, during treatment. The study will also consider bone density of the spine, bone turnover, heart disease risk factors, and psychological state.

Filgrastim for Premature Ovarian Insufficiency

Premature Ovarian Failure

Filgrastim is a Granulocyte-Colony Stimulating factor (G-CSF). It is an FDA approved drug. Very small embryonic-like stem cells (VSELs) are found in the ovary. Animal studies showed that these cells are able to regenerate the affected ovary. Studies on mice have shown that Filgrastim result in recovery of oogenesis after chemotherapy-induced gonadal failure (in 2013, 2014, and 2015).

Flexible GnRH Antagonist vs Flare up GnRH Agonist Protocol in Poor Responders

InfertilityPremature Ovarian Failure

The purpose of this study is to compare ovulation induction using a flexible GnRH antagonist protocol and flare up GnRH agonist protocol in IVF patients with poor response to ovarian stimulation. Our hypothesis is that the antagonist protocol provides better IVF outcomes compared to the flare up protocol in this group of patients.
