56 Clinical Trials for Various Conditions
This prospective randomized trial will assess the relevance, if any, of a corpus luteum induced by hCG in transfers of thawed embryos.
The GETSET trial is a prospective randomized trial designed to evaluate the clinical outcomes of incorporating preimplantation genetic testing for aneuploidies (PGT-A) in elective single embryo transfer in women between 35 and 40 years of age.
Sleep is a critical component of daily life that significantly influences health and well-being. Despite the integral role sleep plays in life, its effect on women's reproductive health, and its subsequent impact on fertility, is largely understudied. The purpose of the SLEEP Study is to investigate the link between sleep and fertility. Participants will use a wireless wearable device mounted on the finger to measure sleep in the weeks preceding and following an embryo transfer during treatment with in vitro fertilization. The investigators hope that these findings will inform future therapies that improve sleep and fertility outcomes.
The goal of this randomized clinical trial is to compare frozen embryo transfer protocols in patients undergoing a second frozen embryo transfer (FET) after a unsuccessful first programmed FET cycle as a possible treatment for people undergoing infertility treatment. The purpose of this research study is to: * Determine if there is a difference between FET protocols in patients who require a second FET cycle. * Investigate if switching the FET protocol after a failed programmed cycle is beneficial for patients undergoing a second FET cycle. * Examine pregnancy outcomes including obstetrical and neonatal outcomes (if applicable) * Obtain uterine flexibility/stiffness measurements via transvaginal ultrasound prior to the embryo transfer procedure. This is called shear wave elastography. Participants will be randomized in their second FET transfer attempt to either another programmed protocol or a modified natural protocol.
To determine if the mean elasticity value (measured in kilopascals, kPa) of a patient's endometrium, myometrium and cervix in a sonographically normal appearing uterus predict frozen embryo transfer (FET) success and long term reproductive outcomes when measured the day prior to FET.
NatPro is a two-arm, parallel-group, multi-center, randomized trial in which women undergoing frozen embryo transfer (FET) will be randomized to receive either a modified natural cycle (corpus luteum present) or a programmed cycle (corpus luteum absent).
The proposed study is a single-blind randomized controlled trial which seeks to characterize implantation rates following embryo vitrification and subsequent warming with both slush nitrogen and liquid nitrogen. After warming, implantation rates and pregnancy outcomes will be assessed.
This research is a prospective study in which the purpose is to investigate the clinical outcomes following the transfer of a mosaic embryo (presence of both chromosomally normal and abnormal cells) that has been screened for preimplantation genetic testing (PGT).
Patients who have been previously surgically diagnosed with endometriosis and have embryos predicted to be euploid after in vitro fertilization will be divided into 2 groups via randomization. The test group will receive Elagolix for 60 days prior to starting frozen embryo transfer preparation. The control group will be given leuprolide acetate every 28 days x 2 prior to starting the frozen embryo transfer preparation. Comparative implantation rates between two groups of patients will be evaluated
The purpose of this pilot study is to evaluate whether a decrease in endometrial thickness (compaction) prior to progesterone exposure (endogenous or exogenous) to the day before a single frozen embryo transfer has an impact on the clinical pregnancy rate with euploid embryos in exogenous hormone and modified natural thaw cycles. Information derived from this study may give insight on ways to improve pregnancy rates in cryo-thaw cycles.
This will be a randomized controlled trial to compare if physician contact within the period from embryo transfer to serum pregnancy test decreases anxiety levels for first-time IVF patients.
Pregnancy is a unique period which requires alterations in the immune system to allow for tolerance of a haploidentical fetus. The goal of this study is to measure maternal blood levels of proteins known to promote immune tolerance in early implantation and pregnancy to look for associations between tolerance, miscarriage and failed embryo transfer. Establishing predictive factors of miscarriage and failed in vitro fertilization could have implications for a large portion of couples and serve to guide current and future family planning efforts.
The purpose of this small-scale pilot study (10 patients) is to test the study protocol for an RCT comparing IVF outcomes between day 3 and day 5 embryo transfer in patients with five or fewer embryos in a fresh embryo transfer in vitro fertilization (IVF) cycle. Information derived from this RCT would allow us to maximize the chances of success for these patients undergoing IVF.
In ART (assisted reproductive technology) cycles, embryos are transferred to a woman's uterus after in-vitro fertilization (IVF) in a laboratory. Usually, hormones (progesterone) are given to the patient after transferring the embryo, as a supplement, in order to mimic the natural hormones that would normally be secreted in an unassisted pregnancy. This study will identify whether additional gonadotropin-releasing hormone (GnRH-agonist) administration, a natural hormone secreted from the hypothalamus, will improve the clinical pregnancy and live birth rates when using IVF.
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
This study evaluated whether laser acupuncture at the time of embryo transfer (following in vitro fertilization) improves implantation rates. Patients were randomized to one of 4 groups at the time of embryo transfer: 1) laser acupuncture, 2) needle acupuncture, 3) sham laser acupuncture, 4) no treatment.
The purpose of the current study is to evaluate the effect of preimplantation genetic screening (PGS) by next generation sequencing (NGS) compared to standard morphological assessment of embryos on pregnancy rates through a randomized controlled trial (RCT). All embryos will be vitrified and a single embryo transfer (SET) will be performed with either screened or unscreened embryos depending on randomization.
To determine whether the of vaginal progesterone replacement for frozen embryo transfer results in equivalent live birth rates to intramuscular injection progesterone replacement.
The investigators propose to perform a clinical randomized trial to evaluate the effect of a frozen-thawed embryo transfer and a fresh embryo transfer on pregnancy and implantation rates; with the added benefit of a blastocyst biopsy and whole chromosome analysis by Next Generation Sequencing (NGS).
The endometrium is deprived of signals form the embryo in IVF conditions. Studies suggest that placing HCG into the uterus prior to embryo transfer can enhance implantation.
Techniques to improve pregnancy and delivery rates in IVF cycles have focused not only on the embryos transferred, but also the conditions in the uterus at the time of transfer and implantation. Prior studies have shown that embryos secrete human chorionic gonadotropin (hCG) prior to implantation. However, in IVF cycles, the embryos have limited time to secrete hCG before implantation must occur because embryos are placed into the uterus rather than traveling there from the fallopian tubes. Recent studies have shown that the introduction of hCG into the uterus prior to embryo transfer may make the uterus more receptive to implantation. These studies involved day 3 embryos and the investigators are seeking to evaluate the potential benefits of hCG on implantation rates of blastocysts (day 5 or day 6 embryos). The purpose of this study is to determine whether infusion of human chorionic gonadotropin (hCG) into the uterus immediately prior to embryo transfer results in increased implantation rates. The entire IVF cycle, fresh or frozen, will be conducted per routine. All laboratory culture conditions will be per routine. In fresh and frozen IVF cycles, an embryo transfer will be performed per routine. At the time of embryo transfer, participants will be randomly assigned to either the control group or the hCG group. Patients in the hCG group will have a mock embryo transfer with 20µL of transfer media including 500IU of hCG. Patients in the control group will have a mock embryo transfer with 20µL of transfer media. All post-transfer care and pregnancy monitoring will be identical and per routine protocol.
This study seeks to compare the pregnancy and delivery rates of patients who undergo a single embryo transfer, when the embryo has been tested and determined to be chromosomally normal, with pregnancy and delivery rates of patients who undergo a two (2) embryo transfer of untested embryos.
This study seeks to determine if patients with a history of failed fresh embryo transfer(s) will have increased success rates with embryo cryopreservation and subsequent thawed embryo transfer when compared to fresh embryo transfer.
Evaluation of embryo quality in the fresh cycle as a predictor of outcome from frozen embryo transfer.
We are examining whether pregnancy rates differ based on day of embryo transfer in patients who replace all available embryos after an In vitro Fertilization (IVF) cycle. Patients must be undergoing IVF treatment at Stanford University and patients will not receive compensation for their participation (no medical costs covered or patient payment for participation).
26% of all ART cycles performed in the USA in 2003 (CDC data) are frozen embryo transfers (FET) and transfer of embryos resulting from egg donation (ED) to recipients. The typical protocol used to prepare a recipient for ET involves GnRH agonist (Lupron, Tap Pharmaceuticals) to down regulate the patient. A GnRH antagonist, such as Cetrotide (EMD Serono), is comparable to GnRH agonist and FDA approved to prevent spontaneous ovulation with ART treatment, and its usage decreases significantly the number of injections that the patient receives with treatment. The working hypothesis for this study is that the GnRH antagonist (Cetrotide) can be used instead of an agonist to achieve effective down regulation in FET and ED cycles. Presumably, patients will prefer Cetrotide over Lupron because of the markedly fewer injections required.
This is a retrospective review of treatment outcomes from fertility clinics in The Prelude Network who have used Igenomix for PGT-A and have transferred embryos with initial chaotic results, regardless if re-biopsy was performed.
