Filter by:The aim of this randomized controlled trial is to compare the efficacy of oral dydrogesterone vs. micronized vaginal progesterone for luteal phase support in frozen-thawed embryo transfer cycles.
This study evaluates clinical pregnancy rates, obstetrical outcome parameters, costs and patient preferences in natural cycle versus artificial cycle frozen embryo transfers (FET).
In recent years, frozen-thawed embryo transfer procedure (FET) has been widely used to increase the cumulative pregnancy rate per IVF-cycle: which is the best preparation protocol remains a matter of debate. A retrospective analysis was conducted between 2012-2017. The aim was comparing clinical pregnancy rate (CPR) of pure natural cycle frozen-thawed embryo transfer (NC-FET) versus natural cycle frozen-thawed embryo transfer with hCG-triggered ovulation (mNC-FET).
The purpose of this study is to compare pregnancy outcomes of frozen-thawed embryo transfer after endometrial preparation with vaginal estradiol or transdermal estradiol and to evaluate women's satisfaction
The objective of this study is to determine the impact on clinical pregnancy rate of withholding routine prophylactic antibiotic therapy during IVF. The hypothesis is that withholding antibiotic prophylaxis will be non-inferior to routine administration. To test this hypothesis, the investigators will conduct a randomized controlled non inferiority trial. Additionally an exploratory study will be conducted among the first 30 patients undergoing their first cycle enrolled to evaluate the microbiome across the IVF cycle, in addition to the human virome
Despite these revolutionary changes in the laboratory, little has changed with the process of embryo transfer (ET). A study to prospectively evaluate the role of cervical mucus removal prior to embryo transfer on pregnancy rates in ART will be undertaken.
Information regarding the optimal timing for frozen-thawed embryo transfer (FET) following a stimulated in vitro fertilization (IVF) is lacking. One option is to perform FET in the first cycle following the stimulated IVF cycle, i.e. immediate transfer. Another option is to postpone FET for at least one menstrual cycle, i.e. delayed transfer. This randomized study aims to compare the ongoing pregnancy rate of immediate versus delayed FET following a stimulated IVF cycle.
It has been previously shown that although the activation of the embryonic genome can begin as early as two days of initiation of the embryonic development (D2), it is expressed on day 3 (D3). Without this activation, the embryo can not continue its development. Therefore, it has been suggested that extended culture to blastocyst stage could be an option to identify and better select embryos that have been able to carry out this activation. The purpose of this study is to compare cumulative pregnancy and live birth rates following transfer of cleavage embryos or blastocysts.
The study aims to know whether starting progesterone luteal support in intra cytoplasmic sperm injection (ICSI) cycles on the day of ovum pickup affects the degree of difficulty of embryo transfer compared with starting luteal support on day of embryo transfer
This study evaluates the outcomes of frozen-thawed embryo transfer (FET) success rate with modified luteal support - addition of a single injection of HCG and GnRH-agonist, on day of ET and 4 days later, respectively vs. traditional luteal support with vaginal progesterone only in ovulating women.
