NCT00194207
The purpose of this study is to identify elements of a patient's demographics, history, and clinical presentation that may aid in differentiating between patients with an ectopic pregnancy, miscarriage, or normal intrauterine pregnancy. This study will also evaluate serial levels of human chorionic gonadotropin in the serum of these patients, as another way to make the diagnosis.
NCT00419510
The objectives of this study are to develop a Culturally Tailored Genetic (CTGC) protocol for African American women and evaluate its impact on decision making and satisfaction about BRCA1/2 testing, quality of life, and cancer control practices compared to Standard Genetic Counseling (SGC). A secondary objective of this study is to identify African American women who are most and least likely to benefit from CTGC vs. SGC.
NCT00596739
A correlation between obesity and male fertility has been observed in a few clinical studies. Normal weight men appear to have higher sperm concentrations and sperm motility when compared to obese men, suggesting that weight loss might improve sperm function. However, there also are reported cases of severe male factor infertility following weight loss surgery in previously fertile men. The aim of this study is to determine if there are differences in the semen analyses and hormone levels of men obtained before and after undergoing weight loss (bariatric) surgery. This will direct future research and treatment.
