Filter by:Progesterone levels measured in blood/serum of patients on the day of ovulation induction following controlled ovarian stimulation for in vitro fertilization may be associated with pregnancy outcome. The hypothesis is that higher progesterone levels are associated with lower implantation rates due to changes in the endometrial receptivity.
This observational study will examine the safety and efficacy profile of Elonva (corifollitropin alfa) when administered in Korean women undergoing controlled ovarian stimulation (COS) in combination with a gonadotropin-releasing hormone (GnRH) antagonist for the development of multiple follicles in an assisted reproductive technology (ART) program.
Environmental pollutants might be jointly responsible for increase of infertility among women. Especially endocrin active substances seem to be of particular importance. These substances are chemicals which interfere with the physiological system of humans and animals. They have a negative impact on the endocrine system and disturb the functions of organs whose hormones regulate the male and female reproductive system. It is known that exposition to these chemicals lead to subfertility, infertility, raised abortions, birth defects and ovarian malfunction. Additionally it was shown that human embryos have a decreased cleavage rate after IVF when developing from oocytes with elevated concentrations of environmental pollutants. In this study the main focus concentrates on Nonylphenols (NP). Follicular fluids of women with subfertility will be analyzed by a newly developed principle including HPLC and NMR-Spectroscopy. This enables quantitative and qualitative analysis of enantiomers of NP. The results will allow risk estimations for several endocrine active substances, especially NP. Additionally conclusions concerning the correlation between thes substances and subfertility can be drawn.
The aim of the current study was the pharmacokinetic and pharmacodynamic characterization of a single dose administration of four doses of FSH-GEX™ in healthy pituitary-suppressed female volunteers, in comparison with two marketed comparator products.
The object of this study is to determine the benefit of follicular flushing with a double channel needle in a poor responder population for a maximum number of oocytes to be retrieved. The investigators compare two methods of oocyte retrieval with or without flushing. 220 patients undergoing an in vitro fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) have to be included. All patients with less than 5 follicles of 14 mm and more the day of ovulation induction will be included, following a randomized protocol in two groups, Group A: Oocyte retrieval is performed with a single lumen aspiration needle 17G. Group B: Oocyte retrieval is performed with a double lumen aspiration needle 17G. all follicles are flushed with flushing solution in addition to direct aspiration of the follicular fluid, 20CC of flushing medium is provided for all the procedure and flushing medium is collected separately from direct fluid aspiration in order to follow up each oocyte one by one. First criterion of our comparison is the number of oocyte retrieved. Second criteria are: oocyte quality, fertilization rate, number and quality of embryos obtained, clinical pregnancy rate. In Group B the investigators will compare two subgroups: oocytes collected in flush medium and oocytes from direct follicle fluid. Then the investigators will know the capability of oocyte collected after follicular flushing to be fertilized and to increase the success chance of pregnancy for poor responder patients.
Dr. Roseff and his colleagues are conducting a study to evaluate the effectiveness of a novel substance (Inofolic Plus®) in improving oocyte (egg) parameters in subfertile female patients, as measured through Anti-Mullerian Hormone (AMH) blood levels.
This a trial designed to test whether granulocyte colony stimulating factor (G-CSF, Neupogen) can increase the rate of embryo implantation following IVF and embryo transfer. Preliminary data at the Center for Human Reproduction(CHR) and elsewhere suggest that intrauterine infusion of G-CSF can improve endometrial development and can increase implantation rates of embryos.
The main purpose of this clinical research study is to investigate if degarelix can synchronise the growth of the egg sacs in the ovaries and if degarelix has any effect on the lining of the womb.
The success of cancer treatment combined with the trend to delay childbearing is increasing the numbers of women survivors whose childbearing has been interrupted by cancer. For some, treatment has resulted in infertility. Others have been advised to delay pregnancy until a certain follow-up interval or have new fears that pregnancy could be a risk to maternal health. Not least is the concern that children born after a mother's cancer would face increased risks for birth defects or cancer. The specific aims of this project are as follows: 1. To measure the impact of cancer-related interruption of childbearing on women's long-term emotional well-being and health-related quality of life, over and above other demographic and cancer-related factors 2. To find out if becoming a biological or social mother after cancer treatment decreases the long-term psychosocial impact of interrupted childbearing compared to remaining childless 3. To refine the psychometric properties of questionnaires for female cancer survivors measuring Distress about Cancer-Related Childbearing Issues and Attitudes towards Parenthood after Cancer 4. To define targets for a future intervention to improve female survivors' knowledge about childbearing after cancer, decrease distress associated with interrupted childbearing, and promote peer support.
Background: The number of multiple pregnancies is considered to be the most important adverse effect of in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI). IVF or ICSI with transferring only one embryo, elective single embryo transfer (eSET), will reduce this incidence remarkably. Unfortunately, former research has documented that cycles with SET maintain lower pregnancy rates compared to double embryo transfer (DET). Implementation of eSET will require a carefully chosen and thoroughly defined implementation strategy focussed on the couple undergoing the subfertility treatment. This trial will investigate the (cost)effectiveness of a combined patient centred implementation strategy. Objective: The main aim is to compare the effectiveness and costs of implementation of elective single embryo transfer (eSET) in in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), between usual care and a combined patient-centred strategy. Study design: A randomised controlled trial Study population: Couples with a female age less than 40 years ongoing an IVF/ICSI treatment in 2 of the 13 Dutch IVF centres and their 4 satellite/transport centres. Intervention A combined patient centred implementation strategy for eSET in IVF/ICSI. The strategy consists of counselling through an evidence based decision aid and reimbursement of a 4th cycle if couples have chosen for eSET in the first 2 cycles. Primary study parameters/outcome of the study: the eSET occurrence rate, pregnancy outcomes and cost-effectiveness of the combined strategy. Secondary study parameters/outcome of the study: - patient knowledge - patient decisional conflict - patient satisfaction - IVF/ICSI treatment outcome.
