Background: The aim of this study was to determine the outcome of IVF/ ICSI by modification of embryo transfer technique following embryo transfer. Materials and Methods: In this randomized trial study, two groups of infertile women (n = 55) aged %40 years underwent in vitro fertilization or intracytoplasmic sperm injection treatment cycles with or without 0.2 mL of air pushed into the catheter...

Background: One of the main problems in ART is low pregnancy rates. The factors involved in successful pregnancy include; 1. mother related factors such as the status of endometrial receptivity and hormonal status of the mother. 2. embryo related factors such as; number of transferred embryo, embryo scores including: number and size of the blastomeres, and their fragmentation. The aim of the pr...

Background: Controlled ovarian stimulation (COS) has been shown to advance endometrial maturation and affect adversely implantation in assisted reproduction technology (ART) cycles. It has been reported that there is a better embryo-endometrium synchrony in frozenthawed embryo transfer (FET) cycles than fresh embryo transfer (ET) cycles. The Background of this study was to compare ongoing pregn...

OBJECTIVE To determine the relative efficacy of ultrasound-guided embryo transfer and embryo transfer by clinical touch alone. DESIGN Systematic review and meta-analysis of randomized, controlled trials comparing ultrasound-guided embryo transfer with embryo transfer by clinical touch alone. SETTING Infertility centers providing treatment with in vitro fertilization/embryo transfer. PATIE...

background: improvement of assisted reproductive technique (art) results in higher pregnancy rates from positive beta hcg to take home baby statistics. despite developments in culture media allowing blastocyst stage transfer, some centers apply second, third and sometimes fourth day post injection for embryo transfer. this study aimed to compare their reproductive outcomes.   methods : this pro...

background: frozen- thawed embryo transfer is an essential part of art treatment and outcomes of this procedure are associated with several clinical factors. several studies have showed an increase level of ivf outcomes in women with sufficient vitamin d. objective: whether treatment of vitamin d insufficiency can improve pregnancy rates in frozen-thawed embryo transfer cycles. materials and me...

background: the role of embryo transfer (et) in the success of in vitro fertilization/intra cytoplasmic sperm injection treatment is not well understood. in the present study we classified et technique as difficult and easy types according to certain strict criteria, and compared the pregnancy outcome of the two et types.   methods: this study was performed retrospectively on 295 infertile pati...

background: recent reports have suggested that ultrasound-guided embryo transfer (ug-et) might improve pregnancy rates. objective: to determine whether transabdominal ug-et is a useful tool for increasing pregnancy and implantation rates in patients undergoing ivf or icsi. materials and methods: a prospective randomized clinical trial was conducted in 180 patients in order to compare embryo tra...
