Filter by:For an efficient "egg banking" system, an equally efficient cryopreservation strategy that ensures the viability of the oocytes is required. Very recently, improved and new methods are yielding satisfactory results. In particular, vitrification is providing excellent results for both survival and clinical outcomes. However, to evaluate the over all out come there are other parameters to be considered. In this sense, capacity development of embryos generated after oocyte vitrification is a major factor when assessing the viability of vitrified oocytes. Accordingly, the evaluation of the capacity of vitrified oocytes to reach the blastocyst stage will be highly valuable to fully assess the effectiveness of the "egg banking" and its contribution to ovum donation programs. The aim of this study is to evaluate the developmental capacity of vitrified oocytes by their ability to reach the blastocyst stage. The study includes oocyte donation cycles conducted with vitrified versus fresh oocytes.
The purpose of the present study is to assess the influence of the administration of low dose hCG on the endometrium. The study is a randomised trial where 2 groups of patients, undergoing a gonadotropin-releasing hormone antagonist protocol for in vitro fertilization, are studied. In addition to the histological findings, by analysing the correlation of the morphological pattern and gene expression profile of human endometrium on the day of oocyte retrieval in patients of both treatment groups, the investigators want to study the implantation potential.
The purpose of this study is to determine whether the administration of the dietary supplement Spermotrend improves spermatogenesis parameters in subjects with male infertility unrelated to major testicular conditions. The duration of this double-blind placebo controlled phase 3 clinical trial will be 24 weeks. The estimated number of males with infertility to be recruited and randomized for the study is 86.
The current study aims to explore and analyse the decision making process of couples in regards to continuing or discontinuing infertility treatment. A longitudinal, prospective cohort design is used which allows the monitoring of patients over a longer period of time. Data will be collected quantitatively (questionnaires) as well as qualitatively (in-depth interviews) to allow for a more specific and in depth experience than can be obtained by using a questionnaire study. Innovative aspects of the study include: 1. exploration of determinants of continuing and discontinuing infertility treatment by using a comprehensive psychological theory (both surface and in-depth) 2. exploration of gender differences in the decision making process in continuing or discontinuing treatment 3. longitudinal and prospective arm of the study will allow to gain insight into the 'process' 4. prediction of continuing/discontinuing treatment based on psychological variables.
This study tests the hypothesis that controlled ovarian stimulation impairs endometrial receptivity in normal responders.
This study tests the hypothesis that controlled ovarian stimulation impairs endometrial receptivity in high responders.
The aim of this study is to compare the three commonly used hysterosalpingography (HSG) injection devices on the basis of patient pain perception, total fluoroscopic and procedural time, and side effects in a prospective, randomized study. An important and novel secondary outcome is the comparison of the quality of images obtained with these three devices. The investigators hypothesize that the balloon catheter and cervical vacuum cup will be less painful than the acorn tipped cannula and that there will be no difference in image quality between the three groups.
The purpose of this study is to investigate any potential advantages of replacing human chorionic gonadotropin (uhCG) with recombinant human chorionic gonadotropin (recHCG) for final oocyte maturation with regard to Ovarian hyperstimulation syndrome (OHSS)pathophysiology, endometrium receptivity and embryo quality and clinical pregnancy.
The purpose of the study is to compare the pain experience between the patients that have had their transvaginal oocytes retrieval with ultrasound guidance performed with reduced single lumen needle (Vitrolife Sweden AB, Gothenburg) with the patients that have had follicle aspiration needle, 1.4 outer diameter (Vitrolife Sweden AB, Gothenburg), during the procedure.
During IVF treatment, acupuncture at the time of embryo transfer may improve the pregnancy rate. This study aims to compare IVF pregnancy between two groups of patients that received either acupuncture or sham acupuncture (placebo)around embryo transfer
