CONTEXT Substantial concern surrounds the potential health effects of the anthrax vaccine, particularly the potential adverse effects on reproductive processes. OBJECTIVE To determine whether receipt of anthrax vaccination by reproductive-aged women has an effect on pregnancy rates. DESIGN, SETTING, AND PATIENTS Cohort study, based on information from a computer database, of women aged 17 t...

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...

Embryo evaluation and selection is fundamental in clinical IVF. Time-lapse follow-up of embryo development comprises undisturbed culture and the application of the visual information to support embryo evaluation. A meta-analysis of randomized controlled trials was carried out to study whether time-lapse monitoring with the prospective use of a morphokinetic algorithm for selection of embryos im...

background: there is no doubt that luteal phase support is essential to enhance the reproductive outcome in ivf cycles. in addition to progesterone and human chorionic gonadotropin, several studies have described gnrh agonists as luteal phase support to improve implantation rate, pregnancy rate and live birth rate, whereas other studies showed dissimilar conclusions. all of these studies have b...

Background: The objective of this study is to evaluate the progesterone level (P Level) on the day of HCG triggering in GnRh agonist and antagonist protocols, and its correlation with clinical pregnancy rate and miscarriage rate. Premature luteinization during in vitro fertilization (IVF) was commonly happened before the introduction of GnRh analogues. High level of unwanted progesterone that i...

background: premature luteinization during in vitro fertilization was commonly happened before the introduction of gnrh analogues. high level of unwanted progesterone is associated with adverse pregnancy outcome and is thought to be induced by inappropriate lh elevation.objective: to evaluate the progesterone level on the day of human chorionic gonadotropin (hcg) triggering in gnrh agonist and ...

background: general concern is that the pregnancy rate is higher with gnrh-agonist as a protocol of pituitary suppression. gnrh-antagonist protocol provides a shorter period of administration and an easy flexible protocol. objective: in this study, the outcomes of gnrh agonist and antagonist in icsi cycles are compared in normo responder patients. materials and methods: in this randomized clini...

background: the direct effect of hcg on the human endometrium was studied several times. objective: the objectives of this study were to evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhcg) before embryo transfer (et). materials and methods: in this randomized placebo-controlled clinical trial, a total number of 182 infertile patients undergoin...

The pregnancy rate for U.S. women in 2009 was 102.1 per 1,000 women aged 15-44, the lowest level in 12 years; only the 1997 rate of 101.6 has been lower in the last 30 years. Rates for women under age 30 fell during 1990-2009, while rates for women aged 30 and over increased. Rates for teenagers reached historic lows in 2009, including rates for the three major race and Hispanic origin groups. ...
