نویسندگان
چکیده مقاله:
Background: Infertility is one of the most devastating diagnoses for any woman or man to face, and assisted reproductive technology (ART) is a great gift of life given to these people. There are many factors influencing success rate of ART but quality of embryos is believed to improve this rate and therefore is a major challenge. This paper will focus on examining factors affecting the number of grade A embryos retrieved from infertile patients. Materials and Methods: This was a retrospective study using the data of all ART patients who underwent ART in Royan institute during 9 months in 2010. As many patients had no grade A embryo, Zero Inflated Poisson (ZIP) regression model was fitted using STATA version 11 software to find the factors affecting the number of grade A embryos. Results: Maternal age (b=0.066, p value=0.015) and cleavages day (b = -0.756, p value = 0.002) were significant in ZIP regression model. Conclusion: The most important factors affecting the number of grade A embryos retrieved are maternal age and cleavages day.
