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.
Since preimplantation genetic testing (PGT) is being more frequently requested from patients as women pursue infertility treatments at an advanced age with a poorer prognosis, sometimes physicians are compelled to perform several stimulation cycles to obtain more eggs and, consequently, a greater number of biopsied embryos. Hence, the idea of carrying out this study arises as an attempt to optimize each menstrual cycle to the maximum. It is believed that the double stimulation (DuoStim) protocol could be an alternative for this group of patients, allowing to obtain a larger number of oocytes in a shorter period, thus, increasing the number of biopsied embryos and possibly decreasing the interval to achieve a successful pregnancy. The investigators aim to evaluate the potential usefulness of the DuoStim protocol for patients desiring to obtain oocytes as soon as possible. Using PGT, the investigators will compare the rate of euploid embryos per cycle in patients undergoing DuoStim protocol versus patients undergoing two conventional controlled ovarian hyperstimulation in consecutive cycles. Patients will include women with advanced age and poor response. This is a unicentric, prospective, randomized, non-blind, parallel-group controlled phase IV clinical study. The investigators hypothesize that the rate of euploid embryos per cycle is similar in the DuoStim group compared to the group undergoing two conventional controlled ovarian hyperstimulation in consecutive cycles. Furthermore the investigators will evaluate if there are differences regarding the number of total oocytes obtained, the number of mature oocytes, the number of biopsied blastocysts and the MitoScore index of the available euploid embryos.
The main objective of this study is to analyze management of Controlled Ovarian Stimulation (COS) protocols in low prognosis patients, secondly to observe the clinical outcomes (Fertilization Rate, Pregnancy Rate, the Ongoing Pregnancy Rate and the Live birth Rate) and the total units of gonadotrophins consume per M2 oocyte retrieved in this subgroup.
The aim of the work is to determine whether the use of immunomodulatory drugs could improve the reproductive of outcome of infertile patients who have autoimmune thyroiditis with positive autoimmune antibodies undergoing IVF-ET.
The GAVI® closed vitrification system is a CE labelled device licensed for use in human IVF. It has been developed to standardize the process of vitrification and to increase the safety of the procedure. It has been demonstrated that the novel semiautomated, closed vitrification system providing standardized equilibration prior to cryopreservation can produce similar results in terms of recovery rate and Embryo development up to the blastocyst stage as compared to the commonly used Manual Cryotop® open vitrifcation system when applied in a mouse model. Furthermore, its application has resulted in first pregnancies after transfer of vitrifiedwarmed biopsied human blastocyts. Due to limitations of the preliminary studies (application in mouse model; absence of a larger clinical Trial assessing pregnancy and live birth rates in human model etc.) it is of paramount importance to compare the GAVI® vitrification method to the routinely used Cryotop® method in a human IVF setting employing randomization and a-priori sample size definitions. The primary objective of this study is to demonstrate non-inferiority of vitrification using the semi-automated GAVI® closed system over the so-far routinely used manual Cryotop® open system in terms of post-thawing survival rate of 2PN oocytes. The secondary objective of this trial is to study differences in embryo development, clinical pregnancy rate, ongoing pregnancy rate and live birth rate. Furthermore, differences in procedure duration and convenience will be evaluated.
Infertility is defined as a couple's inability to become pregnant after one year of unprotected intercourse in women 35 years old and younger, and for six months in women over age 35 years. In any given year, about 15 percent of couples in North America and Europe who are trying to conceive are infertile
Subfertility is the inability to conceive after 12 months of regular unprotected sexual intercourse. Around 15% of couples suffer from subfertility. As a treatment for subfertility, Assisted Reproductive Techniques (ART) have been a choice for subfertile couples. In Egypt in 2010, Pregnancy Rate was calculated to be 36.2%, Live Birth Rate to be 25.7%. Implantation is the process by which the embryo adheres to the wall of the uterus. Endometrial receptivity plays the most important role for successful implantation after embryo quality. It is estimated that up to 70% of early pregnancy losses are due to failure of implantation. Despite extensive research, the embryo-maternal dialogue that orchestrates the implantation process is still not fully understood. Much effort has been done in the last decades to detect factors affecting Implantation and improve endometrial receptivity. Human Chorionic Gonadotropin (hCG) is a placental glycoprotein hormone that required to maintain pregnancy. Recent research data demonstrates that hCG is secreted very early by the embryo before implantation to facilitate it. hCG has been proved to cause attraction of inflammatory cells, promote angiogenesis, regulate chemical mediators at the endometrium. These effects proceed the classical role of hCG during pregnancy and could be a directly involved in and facilitating the implantation process. Studies have been conducted to study the effect of injection of different concentrations of hCG inside the uterine cavity before Embryo Transfer (ET) to improve endometrial receptivity and outcomes of In-Vitro Fertilization (IVF) or Intra-Cytoplasmic Sperm Injection (ICSI) cycles. A recent systematic review was conducted on 12 studies performing intrauterine injection of different doses of hCG before ET. Results of this study showed that there is increased pregnancy outcome after injection of intrauterine 500 IU of hCG. The study recommended a definitive large clinical trial with live birth as the primary outcome. There was no evidence that miscarriage was influenced by intrauterine hCG administration, irrespective of embryo stage at transfer or dose of intrauterine hCG. Aim of the study: To detect whether intrauterine injection of hCG before ET improves clinical outcomes in IVF/ICSI cycles.
This pilot study is a collaborative effort between Northwell Health's Departments of Fertility and Radiology.The aim of this study is to evaluate the feasibility of the Sonohysterosalpingography (sonoHSG) for it to be determined as the standard of care. Additionally, it aims to improve the work up of infertility by integrating the examination of structural abnormalities of the Fallopian tubes and uterus into a single radiation free ultrasound guided procedure, the sonoHSG.
Infertility affects many people in Ontario and carries a significant amount of emotional, physical and financial burden to those who experience it. Knowing when a woman ovulates is important for improving a couple's chance to become pregnant naturally and for learning about fertility problems, such as infertility, irregular menses, and hormonal disorders. Currently, there are two reliable methods to confirm ovulation: a trans-vaginal ultrasound or a blood test for progesterone, which is a hormone that only rises sharply after ovulation. However, both are time consuming and expensive. Recently, an inexpensive, home-based urine test strip has been developed to confirm ovulation. The test strip works by measuring urine for a marker of Progesterone, called pregnanediol-3a-glucuronide (PDG). The purpose of this feasibility study is to follow the use of this home-based PDG urinary test strip over the course of one menstrual cycle in 25 female participants. The results of the urine test strip will then be compared to a Progesterone blood test. Participants will be recruited from the general Ottawa, Ontario area The ultimate aim of this study is to provide information for the design of a larger study to determine the accuracy of the PDG urinary test strip. If shown to be as effective in confirming ovulation, this test would provide substantial cost saving to the Ontario health care system and a much more convenient way for women and clinicians to confirm ovulation and determine if women are fertile.
