Background: Currently, frozen embryo transfers contribute an increasing rate of births from assisted reproductive technologies such as in vitro fertilization (IVF). However, very few studies evaluated the neonatal outcomes from frozen embryo transfer. This study aimed to investigate and compare the neonatal outcomes from frozen embryo transfer versus fresh embryo transfers. Materials and Method...

The presence of hydrosalpinx has been reported to negatively affect the pregnancy and implantation rate after in-vitro fertilization (IVF) with embryo transfer. Hydrosalpinges are able to enlarge during ovarian stimulation with a possible increased passage of tubal fluid into the endometrial cavity. We report the effect of hydrosalpinges during the transfer of previously cryopreserved/thawed em...

BACKGROUND The risks of premature birth and perinatal death are increased after in vitro fertilization. These risks are mainly due to the high incidence of multiple births, which relates to the number of embryos transferred. METHODS We performed a randomized, multicenter trial to assess the equivalence of two approaches to in vitro fertilization with respect to the rates of pregnancy that res...

Objective Women undergoing IVF cycles should go successfully through multiple points during the procedure (i.e., implantation, clinical pregnancy, no spontaneous abortion and delivery) to achieve live births. On the other there is a need to consider previous reproductive outcomes and as well as the current cycle. In this study, data on multiple cycles and multiple points during the IVF cycle ar...

Objectives: To compare the clinical outcomes of single fresh and frozen-thawed superior blastocyst transfer in patients for the first transfer. Methods: This study included 770 single fresh blastocyst and 639 single frozenthawed blastocyst transfers from January 2013 to January 2016. All the fresh and frozen-thawed embryo transfer was first transfer for the patients. The patients were divided i...

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 effect of luteal phase supplementation...

Background: Progesterone (PG) is an essential hormone in the process of implantation and pregnancy maintenance. Frozen-thawed embryo transfer (FET) being performed worldwide. This study was designed to investigate whether serum progesterone levels on day prior 5 frozen-thawed hormonally prepared endometrium correlates with outcomes. Materials Methods: A single center longitudinal observational ...

OBJECTIVE To evaluate the effect of hyaluronan-rich transfer medium on pregnancy and implantation rates in fresh and frozen-thawed embryo transfers in Korean women with previous implantation failure. METHODS This retrospective study included 283 blastocyst transfers in patients with previous embryo transfer failure at a private fertility clinic. In the study group (n=88), blastocyst transfers...

BACKGROUND Infertility is a common problem affecting up to ten per cent of married couples. A systematic evaluation of aetiologic factors forms the basis for choice of treatment and future fertility. On the global perspective, Assisted Reproductive Technologies (ART) has become internationally recognised treatment option for some infertile couples. A report on the current outcomes of ART practi...
