Active clinical trials for "Infertility"

The primary objective of this study is to determine the safety and efficacy of pulsatile GnRH delivered from a iontophoretic patch (Lutrepatch) for induction of ovulation in women with anovulatory/ oligoovulatory infertility, compared to placebo and to a reference treatment with clomiphene citrate.

Marcelle Cedars, M.D., Victor Fujimoto, M.D., Mitch Rosen, M.D., Heather Huddleston, M.D., Paolo Rinaudo, M.D., Anthony Dobson, M.D., and Shehua Shen, M.D. from the UCSF Department of Obstetrics and Gynecology and Reproductive Sciences are conducting a study to learn about ovarian stimulation and oocyte maturation to improve fertilization, embryo quality, implantation and clinical pregnancy rates in patients undergoing in vitro fertilization (IVF). Two hormones, follicle stimulating hormone and human chorionic gonadotropin (FSH/hCG) will be compared to the standard one hormone, hCG, for the ovulation trigger. Over the past two decades, the success rate of assisted reproductive technology (ART) has dramatically increased. This increase has largely been attributed to improvements in the laboratory conditions and improvements in ovarian stimulation protocols (those medications used to increase the number of eggs maturing each cycle). Less work has been done on different ways to cause the final maturation of the eggs and the release of the egg from the ovary. The investigators propose to change the final injection prior to the egg retrieval (the ovulation trigger) so that it looks more like what happens in a normal menstrual cycle, where two hormones (both luteinizing hormone (LH) and FSH) increase. The investigators want to find out if this will improve egg quality and increase chances for pregnancy.

This study is to assess whether addition of 2 ng/ml GM-CSF into a specific culture medium will increase the chance of a pregnancy after in vitro fertilisation.

Clinical trial objectives are to investigate the efficacy and safety of a single injection of 100 μg Org 36286 in women weighing 60 kg or less to induce multifollicular development for controlled ovarian stimulation (COS), using daily recFSH as a reference.

The potentially damaging effect of free O2 radicals to cultured embryos may be reduced by adding scavengers to the culture media or by reducing the incubator O2 levels. However, lowering the O2 in the culture environment can be expensive, troublesome and may not be justifiable. The objective of this study is to evaluate the effect of lowered incubator O2 tension on live birth rates in a predominately day-5 embryo transfer program. The hypothesis of this study is that a lowered (more physiological)oxygen concentration in embryo culture incubators will increase live birth rates for in vitro fertilization patients. 230 first-cycle women undergoing routine IVF or ICSI with ejaculated sperm will be randomized in a prospective clinical trial and stratified for patient age and physician. Embryos of patients will be randomly assigned for culture in either a 21% O2 (atmospheric) or 5% O2 (reduced) environment. Clinical endpoints monitored will be rates of implantation, clinical pregnancy, live birth and blastocyst cryopreservation.

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.

Pregnancy rate may be affected by multiple factors such as embryo transfer techniques. Even small differences in embryo transfer methods may affect pregnancy rates. There is an inconsistency about the effect of the removal of cervical discharge on embryo transfer outcomes. Some studies showed that cervical mucus removal before embryo transfer can increase pregnancy rate, however the others could not find any significant effect about the removal of cervical mucus on pregnancy or live birth rates. Given to the conflicting evidences, our study aimed to determine whether the cervical discharge removal has positive effect on pregnancy rate.

In a prospective interventional study, 44 Clomiphene resistant infertile patients were selected from Abolfazl Infertility Clinic of Bushehr University of Medical Sciences. Letrozole was given orally in a dose of 2.5mg, 5mg and 7.5mg, respectively. If the patient displayed no response, the dosage was increased. The size of follicle, endometrial thickness, estradiol, complications and clinical pregnancy rate were evaluated as the final outcome.

The purpose of this study is to determine whether expressive writing can be effective in improving the well-being and sperm quality in patients with male infertility.

This was an open, randomized, comparative study using rhCG (Ovidrel) in the induction of final follicle maturation and early luteinization in Chinese female subjects undergoing IVF or ET.
