Filter by:The goal of this clinical trial is to test the effect of modulated specialised immune cells isolated from the patients' own blood when administered to the uterus before embryo transfer on the IVF outcome (implantation, pregnancy and live birth rates). To achieve this, blood will be obtained from eligible participants. Target cells will be isolated and incubated with the tested modulator for 24h, and returned to the uterine cavity 1 day prior to embryo transfer. Researchers will compare the reproductive outcome of the tested intervention to that of a control group who will not receive the investigated cell treatment prior to embryo transfer.
Patients undergoing their first course of in vitro fertilisation receive either gynaecologist guided propofol only sedation or anaesthetist guided full anaesthesia. Patient satisfaction and clinical outcome will be evaluated afterwards.
The goal of this clinical trial is to evaluate the importance of differential O2 tension to the developing embryos. As a secondary aim, we investigate the levels of reactive oxygen species (ROS) in spent media from the developing blastocysts. This is a prospective, interventional multicenter study using sibling embryos. Woman (age 18-41 and normal weight) undergoing assisted reproductive technology (ART) can be included in the study. Patients included in the project will follow standard IVF protocol and treatment. By retrieving ≥ 8 oocytes after pickup and upon prior acceptance by the patient, she/the couple can be included in the study. According to standard treatment, both groups of oocytes will be placed in an incubator with 5% O2.After 3 days of cultivation, the dishes with the study-embryos will be transferred to an incubator with 2% O2. The control embryos will remain in the conventional 5% O2 incubator. On the fifth day, the embryos will be evaluated, and the blastocyst with expected greatest implantation potential will be transferred to the patients uterus. Surplus embryos with expected implantation potential will be cryopreserved. After transfer or cryopreservation, the media from the wells with used blastocysts will be collected and stored for ROS analysis. Value for public Health: If our hypothesis is confirmed, we will be able to optimize the developmental conditions and decreased ROS levels for the embryo in vitro. From a clinical perspective, this could affect the implantation rate of the blastocyst and thus the success of pregnancies for infertile couples while reducing the number of treatments to obtain a viable pregnancy.
GM508 CultActive is a bicarbonate buffered reagent and ready-to-use designed to investigate oocytes of patients with failed fertilization after previous Intracytoplasmatic Sperm Injection cycles. The investigators hypothesize that GM508 CultActive will improve the fertilization rate and embryo development of such IVF patients (a history of poor fertilization, a history of poor embryo quality, and over 40 years old expected challenging to conceive).
The aim of the study is to investigate the confounding factors of chronic endometritis and therapeutic benefits of antibodies targeting plasma cells in women with reproductive failure.
There are various known parameters for assessing ovarian reserve, including ovarian volume, antral follicle count, follicle stimulating hormone (FSH) and Inhibin B at the beginning of the menstrual cycle, as well as anti-Mullerian hormone (AMH). Anti-müllerian hormone is a dimeric glycoprotein and a member of the transforming growth factor β family that plays a role in the regulation of follicular development. AMH is produced by granulosa cells of the early developing follicles in the ovary, and continues to be expressed in the growing follicles until these follicles have reached a size of 4-6 mm and a differentiation state at which AMH becomes receptive for exogenous FSH, and may be selected for dominance.It exerts its biological effects through the receptor AMHR2, which is present on granulosa and theca cells. Considering the important role of the AMH signalling pathway in regulating FSH sensitivity in the ovary and follicular recruitment and selection, it is appropriate to consider that variation in the genes encoding key proteins in the pathway may influence ovarian response. The aim of this study is to investigate the effect of the distribution of single gene polymorphisms of the AMHR2 receptor gene A-482G/rs200255 in patients with unexplained infertility and to compare this distribution with the distribution in women without infertility.
The aim of the study is to investigate the role of oxidative stress in female infertility and the relationship between the stress as it is illustrated by questionnaires, serum markers, follicular fluid markers, and ovarian response in assisted reproduction.
This study aims to demonstrate a reliable method of selecting gender specific sperm. X-bearing spermatozoa and Y-bearing spermatozoa will be identified from the density gradient layers. The selected gender specimen will then be utilized for assisted reproductive fertilization- in vitro fertilization or intrauterine insemination which are routine standard of care procedures.
This is a multicenter, randomised controlled trial. The investigators plan to randomise 836 participants to the immediate FET or the postponed FET from the day of oocyte retrieval to the last day of that menstrual cycle in a 1:1 rate. Primary outcome will be the live birth rate after the embryo transfer.
Thanks to recent advances in clinical practice and laboratory, embryo cryopreservation has become the first-line procedure in assisted reproductive technology. Improved laboratory techniques have increased the number of available embryos derived from an in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycle. Implementation of a single embryo transfer policy to improve vitrification, improve postwarm embryo survival rates, and reduce multiple pregnancies without reducing cumulative birth rates has contributed to an increase in the number of frozen-warms (1,2) Embryo freezing; It is becoming an adopted practice for an increasing number of indications, including prevention of ovarian hyperstimulation syndrome, preimplantation genetic testing (PGT), late follicular phase progesterone elevation, and embryo-endometrial asynchrony. In our study, we are investigating the effect of pre-transfer serum progesterone levels on pregnancy outcomes in patients who underwent frozen-thawed embryo transfer.Supplementary progesterone preparations can be used to prevent luteal phase defect and to provide progesterone support in cycle preparations for frozen-thawed embryo transfer(3). The aim in this study is to show the effect of serum progesterone level on the pregnancy results on the day of embryo transfer in natural cycles.
