High implantation success following in vitro fertilization cycles are achieved via the transfer of embryos with the highest developmental competence. Multiple pregnancies as a result of the transfer of several embryos per cycle accompany with various complication. Thus, single-embryo transfer (SET) is the preferred practice in assisted reproductive technique (ART) treatment. In order to improve...

OBJECTIVE To determine follicular-fluid neurotrophin levels in women undergoing assisted reproductive techniques for different etiologies of infertility. DESIGN Prospective observational study. SETTING Academically affiliated assisted reproductive techniques unit. PATIENT(S) One hundred six patients undergoing an IVF cycle for different etiologies of infertility. INTERVENTION(S) Assessm...

BACKGROUND This study compares the microdose flare-up protocol to the ultrashort gonadotropinreleasing hormone (GnRH) agonist flare combined with the fixed multidose GnRH antagonist protocol in poor responders undergoing ovarian stimulation. MATERIALS AND METHODS In this randomized clinical trial, 120 women who were candidates for assisted reproductive techniques (ART) and had histories of on...

BACKGROUND Although heterotopic gestation is common in assisted reproductive techniques, it is very rare in natural conception and clomiphene induced pregnancy. Diagnosis and appropriate intervention of heterotopic pregnancy requires a high index of suspicious. CASE In this paper a case of heterotopic pregnancy in a 30-year old woman with hemoperitoneum from ruptured tubal pregnancy with live...

OBJECTIVE To conduct a systematic evaluation of clinical practice guidelines (CPGs) on the use of assisted reproductive technologies. METHODS We searched Medline, the Turning Research into Practice database, and guidelines-specific databases from December 2006 to November 2011. Three reviewers independently assessed each Guideline using the Appraisal of Guidelines for Research Evaluation (AGR...

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...
