background: recent studies of uterine contractility in ivf�embryo transfer led us to consider an alternative, and possibly complementary, explanation for the high implantation rates of blastocysts. it has been demonstrated that myometrial contractile activity influences embryo implantation, possibly through mechanical displacement of embryos. objective: the aim of this study was to examine the ...

Background The endometrial echopattern on the day of human chorionic gonadotropin (HCG) administration and its relationship to the outcome of pregnancy after assisted reproductive treatment (ART) cycles was analyzed, prospectively. MaterialsAndMethods This study conducted between 2013 to 2014. The endometrial pattern was evaluated prospectively on the day of administration of HCG in 280 ART cyc...

Background One of the important complications of assisted reproductive technologies is multiple pregnancy, the aim of the present study was to indentify the risk factors of multiple pregnancy independent of number of transfred embryos. MaterialsAndMethods This retrospective study reviewed the medical records of patients underwent intracytoplasmic sperm injection (ICSI) cycle in Royan Institute ...

BACKGROUND Identifying risk factors that affect excess weight gain during pregnancy is critical, especially among women who are at a higher risk for obesity. The goal of this study was to determine if acculturation, a possible risk factor, was associated with gestational weight gain in a predominantly Puerto Rican population. METHODS We utilized data from Proyecto Buena Salud, a prospective c...

BACKGROUND Maternal smoking during pregnancy is associated with offspring obesity. However, little is known about whether maternal smoking in pregnancy predicts other offspring cardiovascular risk factors including waist circumference (WC), waist-hip-ratio (WHR), pulse rate (PR), systolic (SBP), and diastolic blood pressure (DBP). METHODS We studied a sub-sample of 2038 (50% males) young adul...

The neonatal lupus syndrome consists of transient cutaneous lupus lesions or permanent congenital complete heart block (or hepatic fibrosis), or both, in infants born to mothers with systemic lupus erythematosus (SLE). The frequency of conduction abnormalities was examined in 86 offspring of 53 women affected by SLE. Electrocardiograms from the offspring demonstrated normal sinus rhythm in 84 o...

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...

Objective: In order to evaluate the endometrium by ultrasound in patients undergoing controlled ovarian hyperstimulation (COH) with clomiphene citrate (CC) and human menopausal gonadotropin (HMG) with intrauterine insemination (IUI) to determine the relationship between endometrial pattern and thickness on pregnancy rate (PR). Methods: In this prospective study, 108 infertile couples under...

Ovulation induction (OI) or ovulation enhancement (OE) with gonadotrophins can be a reasonable treatment option for patients with a variety of infertility diagnoses. It must be used with extensive monitoring and management given the risk of multiple pregnancy,especially high-order multiples. This retrospective study evaluated per cycle outcomes of a large cohort of 1452 gonadotrophin OI/OE cycl...

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. 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 clinical trial, ...
