abstract background: for infertile women aged over 35 years, failure of the zp (zona pellucida) to rupture is believed to be associated with a decreased implantation rate in in vitro fertilization (ivf) or intra cytoplasmic sperm injection (icsi). objective: in this research, laser assisted hatching (lah) was offered to patients with advanced maternal age to evaluate a possible benefit. materia...

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...

was definitely established. This shows the grave prognosis of the condition and the importance of recognizing early in preg¬ nancy an underlying nephritis so that the patient may be given the proper treatment. Dr. Stander regards nephritis complicated by pregnancy as a distinct and separate entity or disease process from eclampsia and preeclampsia. Blood studies, the subse¬ quent history of the...

The use of drugs during pregnancy and breast-feeding is a long-lasting debate among scientists. Many of them support the view that the risks are minimal, since the anomalies in fetuses due to chemical compounds are approximately 1%, while others argue that the effects of drug delivery in this special period of life has largely unknown delayed consequences. In clinical practice the dilemma is to...

Background: To assess whether Bromocriptine Rebound Method (BRM), can improve pregnancy outcomes after intracytoplasmic sperm injection (ICSI) cycles. Materials and Methods: In this prospective study, we analyzed data from a total of 117 women who underwent ICSI cycles. Pregnancy outcomes and hormonal data were compared between long protocol and BRM groups. Ovulatory women with normal serum pro...

BACKGROUND Gonadotropin-releasing hormone (GnRH) plays essential roles in embryo implantation, invasion of trophoblastic tissue, and steroid synthesis in the placenta. OBJECTIVE The aim of this study was to evaluate the effect of GnRH antagonist administration on pregnancy outcomes in early implantation period. MATERIALS AND METHODS In this retrospective study, 94 infertile women undergoing...

Aims. To analyze the pregnancy outcomes of circumvallate placenta retrospectively and to predict circumvallate placenta during pregnancy based on its clinical features. Methods. The pregnancy outcomes of 92 women with circumvallate placenta who delivered live singletons at a tertiary care center between January 2000 and September 2012 were compared with those of 9057 controls. Results. Women wi...

background: embryo selection is a vital part of in vitro fertilization (ivf) programs, with morphology-based grading systems having been widely used for decades. time-lapse imaging combined with embryo morph kinetics may proffer a non-invasive means for improving embryo selection. we report the first ongoing and chemical pregnancies using time-lapse embryo scope to select best embryos for trans...

Male mouse urine contains a pregnancy-blocking chemosignal that causes pre-implantation pregnancy failure in recently mated female mice. However, females are able to recognize the chemosignal of the male with which they mated, preventing it from aborting his own offspring. The individuality of the pregnancy-blocking chemosignal is influenced by genes of the major histocompatibility complex (MHC...

Background: Regarding the develops of treatment and management of infertility during recent three decades, success of these methods is limited. Therefore, this study tried to show how corticosteroid therapy improves the results of ICSI. Materials and Methods: This semi clinical trail studywithout control group, including infertile women were candidate to ICSI of Kosar infertility center in urmi...
