Filter by:The purpose of this trial is to study whether addition of different doses of human chorionic gonadotropins during controlled ovarian stimulation for patients undergoing IVF will improve the number of top-quality embryos.
Frozen Embryo Replacement (FER)is a fertility treatment by which stored embryos from a fresh IVF treatment cycle are thawed and transferred into the uterus. Frozen embryos can be replaced either in the middle of a natural menstrual cycle (Natural FER) or in a cycle where the woman takes drugs to suppress her own hormones, and then takes Hormone Replacement Therapy (HRT) to prepare her uterus for the transfer of embryos(HRT − FER). Both are widely used methods of fertility treatment. However, to date no well designed studies have been reported in which the two methods have been compared. This study aims to compare the two treatments in order to establish the best treatment protocol. The study design is a single centre open randomized controlled trial funded by the Oxford Fertility Unit. 100 women who are considering FER treatment at the Oxford Fertility Unit and are eligible for the study will be recruited. After giving their written consent they will be randomised to one of 2 groups: Natural FER and HRT FER. Patients in both groups will be asked to attend one initial visit, which is additional to patients not taking part in the study. Subsequent visits will depend on the treatment group but will not be additional for study participants. All visits requiring ultrasound will involve recording 3−D measurements, which increases the length of each visit by approximately 10 minutes. A patient satisfaction questionnaire would be completed at the end of the cycle. A urinary pregnancy test is performed at home 2 weeks following the embryo transfer visit. If this is positive then further visits to the unit are arranged to confirm the clinical pregnancy. Inclusion in the study would not increase the length of time of either treatment cycle. Follow up would extend to obtaining pregnancy outcome information.
University Reproductive Associates is conducting a pilot study to study the technique of egg freezing. Your participation in this study will provide us with important information to allow us to offer this technology for women wishing to freeze their eggs before cancer treatments. Your participation will include a standard IVF cycle with your eggs being frozen for a brief period of time and then transferred back to you as usual. You will receive a significant reduction in your IVF cycle cost.
The purpose of this study is to evaluate the influence of endometrial biopsy on increasing implantation rate in patients with recurrent implantation failures, 93 women with at least two implantation failures were evaluated. In case group endometrial biopsy was obtained from 48 patients in the luteal phase of previous cycle and implantation and clinical pregnancy rate were compared with 45 patients in control group. The results suggest that in vitro fertilization or intracytoplasmic sperm injection after endometrial biopsy increase pregnancy outcome.
The purpose of the present study is to analyse prospectively if highly purified hMG compared with increased dose of clomiphene citrate has different outcomes in folliculogenesis in ovulation induction cycles.
The overall objective of this trial is to compare the ovarian response in assisted reproductive technology (ART) subjects administered GONAL f® according to the 'Consistency in recombinant follicle stimulating hormone [r-FSH] starting doses for individualized treatment' (CONSORT) calculator versus given a standard GONAL f® dose of 150 International Unit (IU) per day.
30,000 individuals living in Aarhus County, Denmark by Oct 1997 were randomized into two groups. The intervention group received an invitation to be tested for urogenital Chlamydia trachomatis by use of home-obtained and mailed sample (9,000 individuals). The control group received no intervention (21,000 individuals). Outcome measures: Number of tested individuals, number of detected infections, number of women developing PID, ectopic pregnancy or infertility, number of women giving birth to a child, number of women receiving IVF treatment and number of men developing epididymitis. The hypothesis was that more individuals would be tested and treated for infections and that number of long term fertility complications would decline in the intervention group compared to control group.
The purpose of this study is to evaluate two types of embryo transfer procedure. The investigators will compare direct embryo transfer against afterloading embryo transfer.
This study will examine the feasibility, practicality, utility and usability of a semi-quantitative urine pregnancy test (dBest One Step hCG Panel Test Kit) recently approved by the food and drug administration (FDA) for both Professional (physician office) and over-the-counter (consumer) use. The study seeks to: 1. Assess the correlation of this pregnancy test results with serum values (as distinct from urine) hCG. 2. Assess whether or not time of day of urine collection has any impact on the outcome of the dBest test. 3. Assess user comprehension of the pregnancy test, especially assessment of the result.
The rational of the study is to assess the implantation, pregnancy and live birth rates after the transfer of frozen- thawed embryos in natural cycles with spontaneous Luteinizing Hormone (LH)/Progesterone rise or in natural cycles controlled by human chorionic gonadotropin (hCG) for final oocyte maturation and ovulation.
