Active clinical trials for "Infertility"

In this prospective study, the investigators would like to show whether ovarian stimulation with pretreatment of a GnRH antagonist during 3 consecutive days at initiation of the cycle, is possible.

In-vitro fertilization (IVF) of human oocytes followed by the replacement of embryo in the uterine cavity has become a well established treatment for female infertility attributable to damaged fallopian tubes, endometriosis or unexplained causes where alternative forms of therapy have failed. The most commonly used protocols of follicular stimulation now employs follicle stimulating hormone (FSH) and long-acting agonists of gonadotropin releasing hormone (GnRH) to prevent the occurrence of a mid-cycle luteinizing hormone (LH) surge and to ensure the induction of well-synchronized larger cohort of ovarian follicles. The results of a number of studies have demonstrated that in the majority of clinical situations, FSH administration alone is sufficient to achieve successful follicular development. A study had shown that in subjects receiving recombinant human-follicle stimulating hormone (r-hFSH) and recombinant human-luteinizing hormone (r-hLH), pregnancy rates were similar in the younger and older age groups, however, in women receiving r-hFSH alone, there was a significant decline in pregnancy rates for women 35 and older. This particular study also went on to show that the subgroup of women 35 and older, may benefit from supplementary r-hLH. A number of studies have been conducted to assess the safety and efficacy of r-hLH administered concomitantly with r-hFSH in the presence of developing follicles to reduce the rate of growth of intermediate and small follicles while allowing the dominant follicle to continue to progress. This was a Phase III, open-label, multicentre study to evaluate safety and efficacy of addition of Recombinant Human-Luteinizing Hormone (Luveris) to a standard assisted reproductive technologies (ART) protocol.

Stress is a primary reason why in vitro fertilization (IVF) patients drop out of treatment, and it may have a detrimental impact on pregnancy rates, yet there is minimal published research on the efficacy of structured skills-based psychological interventions with assisted reproductive technology (ART) patients. The objective of this study is to determine if women who are randomized to a mind/body (MB) program prior to starting their first IVF cycle will have higher pregnancy rates than controls (C). This is a randomized, controlled prospective study conducted at a private academically-affiliated infertility clinic and includes 143 women ages 40 and below scheduled to undergo their first IVF cycle. Subjects are randomized via computer generated random numbers table to a 10 session mind/body program or a control group and followed for two IVF cycles. The primary outcome measure is clinical pregnancy rate.

This study will be a 6-month intervention that is examining how different dietary approached may be useful for women with Polycystic Ovarian Syndrome (PCOS) who are attempting pregnancy, particularly by measuring changes in weight. Participants will be randomly assigned to following one of two dietary approaches for weight loss: 1) a low-calorie approach to weight loss (reducing caloric intake by approximately 500 calories per day) or 2) a low-fat, low-glycemic index vegan diet. A vegan diet is one that does not contain any animal products (no meat, fish, poultry, eggs, or dairy) but emphasizes plant-based foods, such as fruits, vegetables, whole grains, and legumes/beans. In addition, this diet will be low-glycemic index, which means you will be asked to favor foods that don't cause a quick rise in blood sugar (for example, favoring oatmeal over cornflakes for breakfast). Participants will receive counseling and supporting materials on the dietary approach you are assigned to follow. Both diets are safe and have shown to be effective ways to assist with achieving a healthy weight. The investigators hypothesize that both groups will see improvements in weight and fertility with possible greater improvements seen among participants in the vegan group.

The hypothesis of this randomized double blind study is that the live birth rates are significantly higher after the use of atosiban prior to the embryo transfer in patients undergoing in vitro fertilization (IVF) treatment. This study aims to compare the live birth rates of IVF treatment between patients receiving atosiban and placebo prior to the transfer.

Forty-five infertile women undergoing in vitro fertilization treatment were managed by uterine cavity injection of day 2 embryo culture supernatant before day 3 embryo transfer. No statistically significant differences were found in implantation and pregnancy rates when compared with control group.

The purpose of this study is to determine if the pre-operative levels of sex-hormones can be used to identify the varicocele patients who can expect improvements in their semen parameters following varicocelectomy.

Purpose: Comparing a GnRH agonist and an antagonist protocol for IVF/ICSI with regard to frequency of ovarian hyperstimulation syndrome (OHSS) (1. outcome measure) quality of life (2. outcome measure) live birth rate (2. outcome measure) gene expression profiles of granulosa and cumulus cells, and concentrations of estradiol and vascular endothelial growth factor in follicular fluid(not only compared between GnRH agonist and antagonist protocol, but also between patients with OHSS and no OHSS and patients becoming pregnant and not becoming pregnant (2. outcome measure), and number of oocytes removed per treatment, number of embryo transfers per treatment and number of spontaneous abortions per treatment (these three parameters are tertiary outcome measures). In addition to the above mentioned efficacy outcome measures the safety outcome measure "frequency of known side-effects" will be compared between the two protocols.

The goal of this study is to determine the effect of Healing Touch (HT) on the stress, anxiety, and self-efficacy experiences of women undergoing in vitro fertilization (IVF) in a randomized, controlled design. HT is a gentle, non-invasive form of energy-balancing work that promotes relaxation.

To compare the efficacy and safety of highly purified menotropin (Menopur®) with that of follitropin beta (FOLLISTIM®) in patients who are undergoing gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization (IVF) cycles
