Introduction Smoking is a serious problem for the health care system. Many of the compounds identified in cigarette smoke have toxic effects on the fertility of both females and males. The purpose of this study was to determine whether smoking affects clinical factors during IVF/ICSI therapy in a single-center reproductive unit. Material and Methods In a retrospective study of 200 IVF/ICSI cy...
INTRODUCTION Ovarian Hyperstimulation Syndrome is a complication of controlled ovarian hyperstimulation during cycles of Assisted Medical Reproduction. The objective of this work was to analyze those cycles to achieve a better knowledge of this pathology, namely risk factors and strategies for prevention and treatment of Ovarian Hyperstimulation Syndrome. MATERIALS AND METHODS Retrospective a...
OBJECTIVE To compare the pregnancy outcome in patients undergoing in vitro fertilization-embryo transfer (IVF-ET) cycles, using human derived follicle-stimulating hormone (FSH) or recombinant FSH for ovarian stimulation protocols. DESIGN Prospective, multi-centre, randomized controlled trial. PATIENTS 115 infertile patients undergoing a first attempt of in vitro fertilization and embryo tra...
A Higher Ovarian Response after Stimulation for IVF Is Related to a Higher Number of Euploid Embryos
This study has analysed the relationship between ovarian response and the number of euploid embryos. This is a post hoc analysis of a subset of data generated during a prospective cohort study previously published. Forty-six oocyte donors were subjected to ovarian stimulation with 150 IU of rFSH and 75 IU of hp-hMG in a GnRH agonist long protocol. Preimplantation genetic screening was performed...
INTRODUCTION Obtaining an adequate number of high-quality oocytes is a major challenge in controlled ovarian hyperstimulation (COH). To date, a range of hormonal and clinical parameters have been used to optimize COH but none have significant predictive value. This variability could be due to the genetic predispositions of single-nucleotide polymorphisms (SNPs). Here, we assessed the individual...
Background Since the success rate in older poor-responder (POR) infertile women is expected to be extremely low irrespective of the treatment protocol, clinicians continue the search for biomarkers which may predict cases in which proceeding with follicle aspiration may be appropriate. Experimental studies on murine model suggest that SCF(Stem- Cell-Factor) produced by ovarian cumulus granulosa...
سابقه و هدف: القای رشد و تکامل اووسیت نارس در محیط آزمایشگاهی یکی از روش هایی است که اخیراً در فن آوری های کمک باروری توجه بسیاری از محققین را به خود جلب نموده است. این روش برای زنان مبتلا به سرطان و تخمدان پلی کیستیک حایز اهمیت است. علی رغم استفاده از محیط های کشت مختلف، تاکنون یک محیط مناسب ایده آل جهت کشت اووسیت های نارس گزارش نشده است. با توجه به گزارش مواردی از موفقیت و به منظور تعین تأثیر ...
