BACKGROUND To compare luteal phase bleeding and pregnancy outcomes in normogonadotropic patients receiving progesterone vaginal gel (PVG) or intramuscular progesterone (IMP) injections. METHODS In this retrospective cohort study, data from 270 patients (292 cycles) undergoing day-3 fresh embryo transfer were analyzed. PVG, 90 mg daily (170 cycles) or IMP, 50 mg daily (122 cycles) began at egg...

CONTEXT Many pregnancies are unintended, particularly in certain population groups. Determining whether unintended pregnancy rates and disparities in rates between subgroups are changing may help policymakers target reproductive health services to those women most in need. METHODS To calculate rates of unintended pregnancy and related outcomes, data on pregnancy intendedness from the 2002 Nat...

We compared school-based abstinence-only programs with those including contraceptive information (abstinence-plus) to determine which has the greatest impact on teen pregnancy. The United States has one of the highest rates of teen pregnancy in the industrialized world. Programs aimed at reducing the rate of teen pregnancy include a myriad of approaches including encouraging abstinence, providi...

This study aimed to evaluate if single medium is better than sequential medium at improving ongoing pregnancy rates in patients undergoing assisted reproductive technology (ART) procedures. The data featured in this meta-analysis were extracted from four randomized controlled trials yielded from a systematic search carried out on electronic databases. The primary endpoint was ongoing pregnancy ...

objective: polycystic ovary syndrome (pcos) is highly associated with anovulatory infertility, features of the metabolic syndrome, including obesity, insulin resistance and dyslipidemia. serum concentrations of high sensitive c- reactive protein (hs-crp) were significantly higher in obese than in non-obese pcos patients at baseline suggesting that the relationship between elevated hs-crp levels...

objective: the aim of this study is to examine the effect of the embryo transfer (et) day on clinical pregnancy success rates in in vitro fertilization-et (ivf-et) cycles. materials and methods: in this retrospective study, we divided patients with infertility who underwent ivf-et with fresh embryos into two groups depending on whether the et was performed on weekdays or weekends. the main outc...

background: intrauterine insemination (iui) is the first therapeutic step in assisted reproductive techniques and many factors, including male and female infertility and technique-dependent factors, have been reported to influence pregnancy rates after iui. methods: we carried out this retrospective study on 1201 couples undergoing 3012 intrauterine insemination cycles during 2002 to 2009. preg...
