Filter by:This study is focused on analysing the application of ultrasound scanning techniques as new biomarkers in reproductive medicine. Those biomarkers are based on the analysis of ultrasound texture in different areas of uterine tissue, using 2D/3D ultrasound scanning. Investigators will use the algorithm Text® to analyse the ultrasound texture of the endometrium and myometrium. The aim of the project is to study if it is possible to obtain measurable, objective and reproducible data in healthy volunteers which can be used to predict pregnancy and determine the best moment to perform embryo transfer in assisted reproductive technology (ART) cycles
This study intends to solve the following problems: whether use dexamethasone can obviously decrease transplant cancelling probability in fresh embryo transplant cycle or not, reduce time and frequency going to hospital repeatedly for patients need frozen embryo transplant or not, and reduce the economic burden for patients or not; By comparing pregnancy rate of single transplant, hope to make clear in IVF-ET treatment for patients progesterone increases to a certain level whether it is a good choice to transfer fresh embryo after dexamethasone treatment, or frozen embryo transplant is better.
This study is designed to generate a comprehensive survey of the use on the market of the Anecova device within its intended indications according to the Instructions For Use. The Anecova Registry is part of the Anecova quality system, to enable the Post Marketing Surveillance and the Post Market Clinical Follow-up.
To study the effect of coenzyme Q10 on semen parameters in men with idiopathic infertility
In polycystic ovary syndrome (PCOS) patients, both in vitro maturation (IVM) and intra-cytoplasmic sperm injection (ICSI) are indicated as optional treatments. Although recently ICSI techniques have been reported as more successful the IVM in achieving pregnancy, they have also become much more expensive for the couples involved. Whilst most high-income countries offer Assisted Reproductive Technology (ART) procedures fully or partially paid by the government, the patients in low or middle-income countries have to cover self-fund infertility treatments. With limited resource, a study conducting based on the prevalence - based cost - effectiveness analysis is necessary for health managers, policy makers and especially to assist patients' decision making in these countries. However, there are still limited published studies that have evaluated the cost-effectiveness of these strategies are available in the literature. This study is conducted based on the prevalence - based cost - effectiveness analysis from the patient's perspective. Activity - based costing method is used to cost in all levels of the healthcare system, which the patients have to pay directly or indirectly. It also analyses incremental cost - effectiveness to evaluate the cost - effectiveness of IVM and ICSI in PCOS women.
Repeated implantation failure（RIF） is a insurmountable bottleneck in assisted reproductive technology, many studies have considered that the cause of two-thirds of implant failure is the decreased endometrial receptivity. Human chorionic gonadotropin (hCG) is an early pre-plant signal molecule secreted by the embryo, it can promote endometrial proliferation, increase blood flow and promote embryonic adhesion and inhibit self-regulate apoptosis of trophoblast cells. Previous studies showed that: intrauterine injection of HCG before embryo transfer can improve clinical outcomes in IVF/Intracytoplasmic sperm injection(ICSI). But some studies found that the intrauterine injection of HCG can not significantly improve the success rate of blastocyst transfer, and the reason may be the intrauterine injection of HCG time is too late to significantly increase the implantation rate. Would ahead of intrauterine injection of HCG be more effective? Thus, the patients of repeated implantation frozen embryo cycle according to the random principle accepted two kinds of transplants ways: ①intrauterine injection of HCG before blastocyst transfer; ②blastocyst transfer. Try to understand whether intrauterine injection of HCG can significantly improve the clinical pregnancy rate of blastocyst transfer in repeated implantation failure patients.
The purpose of this study is to determine if elevations in oxidative stress, as measured by oxidation-reduction potential (ORP), can distinguish between semen samples from men with abnormal semen parameters from those with normal semen parameters. Static ORP (sORP) results, measured by the MiOXSYS System- a novel technology, will be compared to the current World Health Organization (WHO) semen analysis parameters (5th Edition WHO Laboratory Manual for the Examination and Processing of Human Semen [2010]).
The aim of this study is to test the hypothesis that the pregnancy rates of women (ages 18-50 years) undergoing transfer of vitrified-warmed blastocysts (frozen at less than 41 years of age) as part of their IVF treatment are not different with respect to the administration of progesterone (Crinone® 8% vaginal gel versus intramuscular progesterone).
Polyps are fleshy outgrowths of the inner lining of the womb which may hinder implantation of embryo and lead to subfertility.This study evaluates whether removal of endometrial polyps in womb affects chances of pregnancy in women in whom no other causes of subfertility can be found. Half of the women would have these polyps removed after their consent and the other half who would not consent would not undergo any such intervention
Currently, controlled ovarian stimulation (COS) in oocyte donors is performed by daily injections of gonadotropins( recombinant FSH) plus a GnRH Antagonist usually form 5th-6th stimulation day until ovulation induction with a bolus of another injection of a gonadotropin-releasing hormone (GnRH) Agonist. Injections of the GnRH Antagonist avoid untimely luteinizing hormone (LH) surge and spontaneous ovulation prior to follicular aspiration. There is a preparation of long-acting recombinant follicle stimulating hormone (rFSH= (corifollitropin alfa (FSH-CTP), Elonva®, MSD), that allows that a single subcutaneous injection substitutes the first 7 days of daily gonadotropin injections. On the other hand, a contraceptive oral progesterone only( Desogestrel, DSG) is available for contraception, avoiding the LH surge. It has been described the usefulness of orally administered medroxyprogesterone acetate, 10 mg to inhibit the endogenous LH surge in IVF patients during COS. In donors, by administering a single injection of FSH-CTP and oral desogestrel since the first menstruation day, the total number of injections administered is reduced and less discomfort is experienced without adverse impact on ovarian response. No description of the hormonal and ovarian response under this protocol has been published
