Active clinical trials for "Infertility"

The investigators would like to assess whether selecting mature sperm using PICSI (selecting for sperm that bind hyaluronan) can optimize the IVF outcome of ICSI . Aim Primary outcome: To compare routine sperm selection using ICSI with sperm selection using PICSI plates in terms of implantation and fertilization rates for couples with male factor fertility Secondary outcome : To compare live birth rates ,ongoing pregnancies and miscarriage rates for couples with male factor infertility using routine sperm selection with ICSI compared to using PICSI plates for sperm selection Hypothesis: Sperm selected for ICSI using (PICSI) will reveal increased implantation rates in comparison to sperm selected for conventional ICSI

Uterus transplantation, as a possible future treatment for uterine factor infertility, has been developed in animal species during the last decade. The study protocol includes transplantation of the uterus from a live donor (mother, relative, friend) into women with absolute uterine factor infertility (lack of uterus from birth or due to life saving hysterectomy).The recipient will be treated by standard immunosuppression and transfer of embryos (acquired by IVF before surgery) will be attempted when at least 12 months have passed from transplantation. Approval for a case series including up to 10 patients has been acquired.

Saline infusion sonohysterography and other intrauterine investigations methods may cause uterine cramping, pain and vasovagal reactions. According to few of previous studies the position of catheter placement can affect the magnitude of pain and amount of saline required during the sonohysterography. The purpose of this double blind control trial study is to assess whether the location of the balloon catheter either the uterus or cervix during sonohysterography can affect the magnitude of pain and the rate of vasovagal reaction.

The purpose of this research study is to evaluate a newly developed embryo culture media system for human clinical use in ART.

Ovulation disorders are a common cause of infertility in women. Most of these women can be classified as World Health Organization (WHO) Group II anovulatory patients as they have irregular or absent menstrual cycles but normal serum concentrations of follicle stimulation hormone (FSH) and estradiol. The purpose of this study is to optimize the low-dose-step-up protocol traditionally used for ovulation induction with follicle-stimulating hormone (FSH) in women with anovulatory infertility WHO Group II. Previous studies have established that menstrual cycle history, mean ovarian volume and BMI are significant predictors of FSH threshold dose in women with anovulatory infertility WHO Group II undergoing ovulation induction (Nyboe Andersen et al., 2008). A FSH dosage nomogram has been constructed based on these variables. The aim of this study is to evaluate the clinical use of the nomogram in order to test the use of the variables to determine whether an individualized starting dose of FSH can be used for ovulation induction in anovulatory patients. It is the hypothesis that an individualized starting dose of gonadotrophin will minimize the disadvantages of the treatment and that the stimulation period of the individualized nomogram-based treatment will be 25% shorter than observed in the standard protocol. The primary endpoint is the proportion of patients who reach the criteria for hCG-administration within 14 days of Menopur stimulation. The results of the study will be compared with the data obtained in the Menopur Ovulation Induction Trial (Platteau et al., 2006).

The recent controversy regarding the use of pill for cycle planning in GnRH antagonists IVF cycle has driven the search for new ways to plan IVF cycles in order to avoid weekends or to equally distribute the workload. Recently, mid-late luteal phase oral estrogens seem to be as good as the pill. The investigators will compare OCP vs oral estrogens to plan the initiation of IVF cycles.

The purpose of this study is to determine if using microdots of hyaluronan (PICSI) to select sperm for ICSI will result in increased pregnancies especially with men that have a low hyaluronan binding score (HBA).

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.

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 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.
