AIM The aim of the study was to investigate the association between follicle-stimulating hormone receptor (FSHR) gene polymorphism at Position 680 and the outcomes of controlled ovarian hyperstimulation for in vitro fertilization and embryo transfer (IVF-ET) in infertile women. MATERIALS AND METHODS One hundred and eight patients under 35 years of age who(More)
BACKGROUND We often see patients with a thin endometrium in ART cycles, in spite of standard and adjuvant treatments. Improving endometrial growth in patients with a thin endometrium is very difficult. Without adequate endometrial thickness these patients, likely, would not have reached embryo transfer. OBJECTIVE We planned this study to investigate the(More)
BACKGROUND The transfer of cryopreserved embryos can be timed with ovulation in a natural cycle or after artificially preparing the endometrium with exogenous hormones. Progesterone is essential for the secretory transformation of the endometrium that permits implantation as well as maintenance of early pregnancy. The purpose of this study is to assess the(More)
BACKGROUND Fertilization failure is one of the most problems in assisted reproduction technology (ART). OBJECTIVE The aim of this study was the evaluation of oocytes activation by addition of calcium ionophore in unfertilized oocytes in ICSI cycles. MATERIALS AND METHODS This study was done on 15 ICSI cycles (stimulated with standard long protocol).(More)
15 % of oocytes collected from Assisted Reproductive Technology (ART) cycles are immature. These oocytes may be matured following in vitro maturation (IVM) program. It is possible to cryopreserve the immature oocytes for further use in ART after application of IVM. The aim was to determine the maturation rate and viability of human oocytes that were matured(More)
BACKGROUND Cryopreservation of embryos has been an usual component of clinic in assisted reproductive technology (ART) programs. Recently the dramatic increase in cryobiology activity in the clinical centers has enhanced methods of freezing and improved vitrification protocols are being developed. OBJECTIVE The aim of our study was to assess the effect of(More)
In-vitro fertilization (IVF) relies heavily on controlled ovarian stimulation to increase the number of available oocytes and embryos, and therefore the pregnancy rate. However, the side effects, such as nausea, mood swings, menopausal symptoms, ovarian hyperstimulation syndrome (OHSS), and potential cancer risk of ovarian stimulation may not be avoided.(More)
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(More)
BACKGROUND Human chorionic gonadotropin (HCG), one of the initial embryonic signals, is probably a major regulator of the embryo-endometrial relationship. This study aims to assess the advantage of HCG supplementation during the secretory phase of hormonally prepared cycles for the transfer of cryopreserved-thawed embryos. MATERIALS AND METHODS This study(More)
The incidence of poor ovarian response in controlled ovarian stimulation (COH) has been reported in 9–24 % of IVF-ET cycles. Growth hormone augments the effect of gonadotropin on granulosa and theca cells, and plays an essential role in ovarian function, including follicular development, estrogen synthesis and oocyte maturation. The aim of this study was to(More)
