Active clinical trials for "Infertility"

This is a Phase 2, interventional, prospective, multi-center, randomized, assessor-blind, active-comparator, dose-finding study to evaluate a new investigational long-acting follicle stimulating hormone (FSH) in infertile women who are undergoing an assisted reproductive technology (ART) procedure (In vitro fertilization/Intra cytoplasmic sperm injection [IVF/ICSI]). This study will compare 3 doses of the investigational drug versus a currently marketed drug follitropin alfa (Gonal-f® revised formulation female [RFF] Pen) in regards to the number of fertilized oocytes.

In programmes of IVF, normal women undergo controlled ovarian stimulation using exogenous FSH injections to obtain multiple eggs. The process results in eggs of mixed quality with a broad range of developmental and implantation potential. The aim of the study was to determine whether, treatment with recombinant human LH prior to the FSH injections can improve outcome for women undergoing IVF. High grade embryos implant with a higher frequency and baby delivery rate than poor quality embryos. The mature oocyte is the most important determinant of embryo quality. Early follicles, containing immature eggs, have LH receptors in the theca cells that surround the follicle, and LH stimulates these cells to produce factors essential for normal follicular development. The intent of the study was to use recLH treatment prior to recFSH to treat a cohort of follicles, so that they can all mature together, thus increasing the proportion of high grade oocytes and their subsequent embryos

26% of all ART cycles performed in the USA in 2003 (CDC data) are frozen embryo transfers (FET) and transfer of embryos resulting from egg donation (ED) to recipients. The typical protocol used to prepare a recipient for ET involves GnRH agonist (Lupron, Tap Pharmaceuticals) to down regulate the patient. A GnRH antagonist, such as Cetrotide (EMD Serono), is comparable to GnRH agonist and FDA approved to prevent spontaneous ovulation with ART treatment, and its usage decreases significantly the number of injections that the patient receives with treatment. The working hypothesis for this study is that the GnRH antagonist (Cetrotide) can be used instead of an agonist to achieve effective down regulation in FET and ED cycles. Presumably, patients will prefer Cetrotide over Lupron because of the markedly fewer injections required.

Our goal was to investigate whether early follicular supplementation of the GnRH antagonist to the flexible GnRH antagonist protocol, has a potential to improve IVF-ET clinical results

Purpose of the study is the evaluation of the tolerability (both local and systemic) and the clinical efficacy (in terms oocytes recovered) of subcutaneously versus intramuscularly administered Merional® (IBSA, Lugano - CH) in patients undergoing controlled ovarian hyperstimulation (COH) in an ART programme (IVF).

The primary objective of the study was to provide further clinical and statistical evidence of the efficacy of r-hLIF, in comparison with placebo, administered during the luteal phase after IVF and ET for improving embryo implantation in infertile women with a history of at least 2 implantation failures following transfer of fresh embryos. The secondary objective of the study was to assess the safety profile of r-hLIF in the proposed indication.

Primary Aim Evaluate whether human embryo exposure to physiologic levels of oxygen during culture improves the percentage of women who deliver a baby following in vitro fertilization and embryo transfer. Hypothesis to be tested: Physiologic oxygen tension during embryo culture, which approximates the oxygen tension in the fallopian tube and uterus, improves live birth rate in clinical In Vitro Fertilization Embryo Transfer (IVF-ET). Secondary Aims Evaluate whether human embryo exposure to physiologic levels of oxygen during culture during in vitro fertilization and embryo transfer improves embryo cleavage improves clinical pregnancy rate reduces multiple pregnancy rate reduces miscarriage rate Hypothesis to be tested: Physiologic oxygen tension during embryo culture, which approximates the oxygen tension in the fallopian tube and uterus, improves embryo cleavage and clinical pregnancy rates and reduces miscarriage rates in clinical IVF-ET.

The purpose of this study is to assess the effect of luteal phase supplement (LPS) on pregnancy rate in IUI cycles stimulated with clomiphene citrate.

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.

Placebo-controlled study. Application of nasal oxytocin (8 IU) during intrauterine insemination in 86 patients.
