We examined the published relationship between uterine fibroids and reproductive outcomes. Submucosal fibroids had the strongest association with lower ongoing pregnancy rates, odds ratio, 0.5; 95% confidence interval, 0.3-0.8, primarily through decreased implantation. Cumulative pregnancy rates appeared slightly lower in patients with intramural fibroids(More)
OBJECTIVE To determine whether success rates were similar in Asian and Caucasian women undergoing infertility treatment. DESIGN Secondary data analysis and multivariate modeling. SETTING Clinics reporting to the national Society for Assisted Reproductive Technology registry and a university-based clinic. PATIENT(S) Caucasian and self-identified Asian(More)
BACKGROUND High-density lipoprotein (HDL) is the sole lipoprotein present in follicular fluid (FF). The objectives of this study were to examine HDL lipid composition and associated enzyme activities in FF and serum and to relate these levels to embryo morphology parameters in women undergoing in vitro fertilization (IVF). METHODS Serum and FF were(More)
OBJECTIVE To evaluate ethnic differences in assisted reproductive technology (ART) outcomes in the United States. DESIGN Historical cohort study. SETTING Clinic-based data. PATIENT(S) A total of 139,027 ART cycles from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System online database for 2004-2006, limited to white,(More)
Studies of human trisomies indicate a remarkable relationship between abnormal meiotic recombination and subsequent nondisjunction at maternal meiosis I or II. Specifically, failure to recombine or recombination events located either too near to or too far from the centromere have been linked to the origin of human trisomies. It should be possible to(More)
Women experience a decline in fertility that precedes the menopause by several years. Previous studies have demonstrated a monotropic rise in FSH associated with reproductive aging: however, the mechanism of this rise and its role in the aging process are poorly understood. The purpose of this study was to characterize ovarian follicular development and(More)
BACKGROUND Obesity has risen among women in the USA, including those seeking infertility treatments. In 2007, height and weight were added to the Society for Assisted Reproductive Technology Clinic Online Reporting System (SART CORS), permitting calculation of BMI (weight/height(2)) for the first time using this national dataset. METHODS The SART CORS was(More)
OBJECTIVE To estimate the incidence of endometriosis in an operative cohort of women seeking clinical care and in a matched population cohort to delineate more fully the scope and magnitude of endometriosis in the context of and beyond clinical care. DESIGN Matched-exposure cohort design. SETTING Surgical centers in the Salt Lake City, Utah, and San(More)
OBJECTIVE To systematically review the reporting of race/ethnicity in Society for Assisted Reproductive Technology (SART) Clinic Outcome Reporting System (CORS) publications. DESIGN Systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology of literature published in PubMed on race/ethnicity that(More)
OBJECTIVE To develop a noninvasive method for treatment of uterine fibroid tumors using high-intensity focused ultrasound. Optimal high-intensity focused ultrasound treatment would be dependent on quantitative information about ultrasonic tissue characteristics. METHODS Ultrasonic attenuation and the sound speed of fresh human fibroid tumors and(More)
