OBJECTIVE To evaluate if the outcomes of IVF/ICSI in frozen-thawed embryo transfer and fresh embryo transfer cycles differ in relation to cleavage and blastocyst stages. METHODS Retrospective cohort study to compare IVF/ICSI outcomes between fresh embryo transfer and frozen-thawed embryo transfer cycles, according to the stage of embryo development. Analysis was carried out on 443 consecutive...
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...
the main factors affecting pregnancy and implantation rates are uterine receptivity, embryo quality, and transfer efficiency. embryo transfer (et) is the last step of critically important procedure of in vitro fertilization (ivf) and probably the least successful step in assisted reproductive technology (art) treatment cascade; though simple in most of the cases, it may pose to be the most diff...
OBJECTIVE To determine some major characteristic differences between two consecutive successful and unsuccessful intracytoplasmic sperm injection (ICSI) cycles in poor responders. MATERIALS AND METHODS Sixty women with poor ovarian response as determined using the Bologna criteria underwent ICSI cycles following an unsuccessful trial. Some parameters of both cycles including age, body mass in...
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...
clinical reproductive centers produce large amounts of surplus poor-quality embryos annually, how to maximize the use of these embryos, and which of them have the potential to develop into blastocyst stage and influencing factors were lack of systematic research. objective: to investigate the fate of surplus poor-quality embryos which were cultured to obtain blastocyst, determine the factors wh...
Background: C-reactive protein (CRP) can be increased after hormonal stimulations. The changes of CRP might affect the success of in-vitro fertilization (IVF). Objective: The aim of this study was to determine the possible relationship between the serum CRP level and outcome of controlled ovarian stimulation, and pregnancy rate in patients undergoing IVF or intra cytoplasmic sperm injection (IC...
Background & Aims: Serum progesterone level (as early as 4 weeks gestation) reflects the relation between embryo and corpus luteum. The purpose of the present study was to compare serum progesterone level on day 14 after embryo transfer among 3 groups of patients undergoing intracytoplasmic sperm injection (ICSI) cycles; normal pregnancy (viable intrauterine pregnancy), abnormal pregnancy (misc...
BACKGROUND Sperm of poor quality can negatively affect embryo development to the blastocyst stage. The aim of this comparative prospective randomized study was to evaluate the role of an intracytoplasmic morphologically selected sperm injection (IMSI) in the same infertile couples included in the programme of intracytoplasmic sperm injection (ICSI) due to their indications of male infertility w...
Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and f...
