background: approximately one percent of current live births of the world are conceived via assisted reproductive technologies (art). objective:  the purpose of this study was to compare the developmental status of children born through assisted and natural conceptions at the age of five years. materials and methods:  in a retrospective cohort study, developmental status of 5 years old children...

cumulative embryo score (ces) is one of the many embryo scoring methods which have been developed to help clinicians to transfer high quality embryos and predict pregnancy rate in assisted reproductive techniques (art) cycles. regarding the existing difference in ces calculation this study was done to compare two methods in order to determine the more practical and preferable one. in a retrospe...

The use of assisted reproductive technology is increasing rapidly. Research, although sparse, has resulted in inconsistent findings as to the developmental prognosis for infants conceived by assisted reproductive techniques such as in vitro fertilization and the use of fertility drugs. In the present study, the authors compared twins who were spontaneously conceived with those who were conceive...

For many years, the management of male-factor infertility has been empirical rather than evidence-based. In current clinical practice, assisted reproductive techniques are the most successful methods of alleviating male-factor infertility. To date, it remains unclear what adjuvant actions can be taken to improve the outcome of assisted reproductive techniques for male-factor infertility. Eviden...

Cryopreservation of embryos and gametes has become an indispensible service for infertility treatment. Vitrification is now a prevalent technique for cryopreservation in assisted reproductive technology (ART) replacing, in many cases, conventional slow cooling methodology. Fertility preservation in female patients has become a very topical issue. Various malignant and nonmalignant diseases have...

BACKGROUND Extended in vitro embryo culture and blastocyst transfer have emerged as essential components of the advanced reproductive technology armamentarium, permitting selection of more advanced embryos considered best suited for transfer. AIM OF STUDY The aim of this study was to compare between cleavage stage and blastocyst stage embryo transfer in patients undergoing intracytoplasmic sp...
