Filter by:The purpose of this research study protocol is to collect imaging data on embryos followed to blastocyst stage (Day 5-6) and correlate Eeva parameters with array - Comparative Genomic Hybridization (aCGH) results and ongoing pregnancy rates.
This observational study aims the potential role of serum progesterone levels on the day of oocyte pick-up on the probability of pregnancy, in patients undergoing antagonist IVF cycles. There has been evidence, that increased serum levels of progesterone on triggering day are associated with a decreased probability of pregnancy after IVF. There is no study that investigate assocation between serum progesterone levels on the day of oocyte pick-up and IVF outcomes. This study will be the first in this case.
Infertility is a common problem, affecting perhaps one couple in six, the majority of whom now seek medical care. It is becoming a social challenge because it is responsible for personal and interpersonal discomfort and anxiety. A major obstacle to meaningful study of the epidemiology of male infertility is the difficulty in accurate diagnosis of the presence or absence of a problem. Traditionally, the diagnosis of male infertility is facilitated by the conventional assessment of the semen profile - constructed according to recognized guidelines (i.e. WHO) and including pH, cell count and motility - but no specific biomarkers are available. We sought to determine the oxysterol and fatty acid lipidome with the ai of finding a lipid biomarker useful for the diagnosis of male infertility.
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).
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of childbearing age. However, the optimal infertility treatment for PCOS patients is still a matter of controversy. Despite producing more follicles and more oocytes than other women undergoing controlled ovarian hyperstimulation during an IVF cycle, women with PCOS have comparable or lower pregnancy rates. Additionally women with PCOS patients undergoing IVF have a higher risk of developing ovarian hyperstimulation syndrome (OHSS), which may be aggravated by pregnancy after an embryo transfer in a fresh cycle. Further women with PCOS are thought to have higher rates of later pregnancy complications including spontaneous abortion, pre-eclampsia, and preterm labor that may be related to impaired implantation in the superovulated endometrium. We propose a randomized clinical trial of elective embryo cryopreservation followed by a programmed cycle of endometrial preparation and frozen embryo transfer (FET) compared to fresh embryo transfer in women with PCOS undergoing in vitro fertilization (IVF).
The purpose of this study is to record and evaluate the use of traditional morphology grading combined with Eeva in the treatment of in vitro fertilization.
Worldwide, 1 in 12 couples experience difficulty in getting pregnant and seek the help of assisted reproductive technologies (ART) such as in vitro fertilization (IVF-egg is fertilized by sperm outside the body), ovarian stimulation (medications are used to stimulate egg development) and intra-cytoplasmic injection (ICSI-single sperm is injected directly into the egg). Regardless of the ART procedure being performed, the newly fertilized embryo must still implant into the mothers endometrium (inner lining of uterus). This implantation process in humans is surprisingly inefficient and accounts for up to 50% of ART failures. Intrauterine infusion of hCG prior to embryo transfer has recently been shown to increase pregnancy rates but the cellular mechanism for this increase is unknown. Successful implantation requires the newly fertilized embryo and the endometrium develop in a synchronized manner. This coordinated development is accomplished, in part, by proteins secreted by the embryo which circulate throughout the maternal bloodstream and alert the maternal body organs (i.e. ovary, endometrium, breast, ect) that fertilization has occurred. One of the earliest of these secreted proteins is human chorionic gonadotropin (hCG), which is the molecule detected in over-the-counter pregnancy tests. From previous studies, we know that hCG production by the embryo alerts the ovary to continue producing progesterone, a hormone required for pregnancy. However, very little is known about the direct effect of hCG on the endometrium during early pregnancy in humans. Using animal models, hCG has been shown to induce specific changes in the endometrium, suggesting that embryo-derived hCG may be "priming" the endometrium in anticipation of implantation. The goal of this research study is to examine the direct effect of hCG on the human endometrium and see if this "priming effect" is also present in humans. Findings from this research may reveal whether pre-treatment with hCG can enhance ART outcomes, especially pregnancy rates.
The objective of this study is to explore the effects of weight loss on body composition, metabolic status, reproductive hormones, and ovarian follicle development in obese women with regular menstrual cycles versus obese women with irregular menstrual cycles and/or polycystic ovary syndrome (PCOS).
The purpose of this study is to find out more about tests used to estimate the number of eggs a woman has remaining in her ovaries (her 'ovarian reserve'). It is thought that women who have a greater number of eggs or ovarian reserve may have a better chance of successful in vitro Fertilisation (IVF) treatment than those who have a smaller number of eggs. Accurately predicting the likely outcomes of IVF would be of great benefit for counselling patients before they go through expensive and demanding treatments such as IVF and IVF with Intracytoplasmic sperm injection (IVFICSI). Over the past two decades, many endocrine and ultrasound markers have been designed and are now used as indicators of ovarian reserve. A number of screening tests are utilized to measure these markers, either by ultrasound scanning techniques or taking blood samples. However it is not yet known which, if any, best predict the outcome of IVF treatment. We would like to investigate these various measures of ovarian reserve to determine which are most accurate, particularly for predicting live birth rates, as up to now only poor to moderate quality evidence has been available for this outcome. This will be a prospective cohort study of 300 women who already intend to undergo IVF/IVF-ICSI treatment. Study participants will have one extra blood sample and ultrasound examination, for the purposes of measuring markers of their ovarian reserve, at the start of their IVF/IVFICSI treatment cycle. No other interventions will be required and their treatment cycle will not be affected by their participation in the study.
In order to learn more about women's health issues that occur over the lifespan, the Women's Health Study: from Adolescence to Adulthood is building a biorepository and database. The biorepository collects, processes and stores samples (such as urine, saliva, blood, cells, tissue and peritoneal fluid) until they are needed for research. The database contains de-identified information about our study participants. The biorepository and database are being created to serve as a resource for researchers from Boston Children's Hospital, Brigham and Women's Hospital and outside institutions.
