Active clinical trials for "Infertility"

Approximately 10% of all couples will be diagnosed as infertile. The most efficient infertility treatment is In-Vitro Fertilization (IVF). One major determinant for success is production of an adequate number of oocytes (eggs) from the female in order to finally have good-quality embryos and finally acceptable pregnancy and delivery rates. Some women will not respond adequately to hormonal stimulation and will only a small number of oocytes. Therefore, the chances of finally having a successful delivery are significantly reduced. Although the specific definition of this situation is controversial, these patients are diagnosed as having "low ovarian response". This condition is more prevalent in older IVF patients as part of the reproductive aging process; it is possible at any age. Currently, the understanding of "low ovarian response" is limited, and although many therapeutic approaches have been suggested, no treatment has been proven significantly efficient. DHEA is a pro-hormone produced by the adrenal gland and the ovary. DHEA serum levels become lower with age and in some chronic diseases. Therefore, some believe it may be beneficial as an 'anti-aging' factor. DHEA pills are available as a food-supplement, without need for prescription in the US. DHEA is involved in the regulation of follicular growth in the ovaries. In a 2000 report, five IVF patients who had low ovarian response were treated with oral DHEA (Casson et al, Hum Reprod 2000;15:2129). A small increase in the ovarian response to hormonal stimulation was noticed. Barad and Gleicher reported their relatively extensive experience, summarizing treatment outcome in 25 IVF low-responders treated with oral DHEA pills (Barad and Gleicher, Hum Reprod 2006; 21, 2845). They observed increased increases in fertilized oocytes, normal day 3 embryos, and number of embryos transferred after DHEA treatment compared with a previous treatment outcome before DHEA. Based on this observation, DHEA may appear useful for improving IVF outcome in some patients. However, a prospective randomized study on DHEA supplementation for IVF patients was not yet published. Our aim is to conduct such a study, focusing on IVF patient with low ovarian response.

The purpose of this study is to compare the efficacy of two controlled ovarian stimulation protocols, the GnRH agonist protocol, widely known as the "long" protocol, and the flexible GnRH antagonist protocol, in terms of pregnancy rates and embryological data, in infertile patients receiving IVF treatment.

Successful embryo implantation needs an optimum embryonic development with a receptive endometrium. Endometrial thickness is an independant factor for endometrial receiptivity. The aim of that trial is to assess the benefecial effect of platelt rich plasma in copmarison with standard hormonal therapy.

Comparison between effect of enoxaparin and clopidogrel on improving pregnancy rate in ICSI

The supplementation of Dehydroepiandrosterone (DHEA) has been used in some centers for patients with previous poor ovarian reserve and response in an attempt to improve pregnancy outcomes. However, there still has controversy on the clinical effect on the 75mg/d for the use,especially in Asian people. Whether the double dosage of DHEA in patients with poor ovarian reserve and response in China can improve the IVF outcome with little side effect is unknown. The aim of this randomized controlled study is to compare the effect of a higher dose (150mg daily) and a standard dose (75mg daily) of DHEA on the number of oocytes obtained in poor ovarian responders. The effect of DHEA action on the cumulus cells will be examined.

Acupuncture is one of the traditional Chinese practices widely used in China for more than 3000 years. In recent years, the use of acupuncture within infertility has gained popularity all over the world, but there is no research describing the use of acupuncture in infertility of incompletely obstructive fallopian tube. In this paper, we present a research design evaluating the effects of acupuncture on incomplete fallopian tube obstructive infertility. This is a randomized, control acupuncture and signal-blind trial. A total of 120 patients will be enrolled in this study and will be randomized into two groups. True acupuncture plus hydrotubation or control acupuncture plus hydrotubation will be performed for 12 weeks. The purpose of this paper is to evaluate the additional value of acupuncture on the tubal patency rate and pregnancy rate beyond Hydrotubation ,therefore to guide clinical.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of childbearing age. However, the optimal infertility treatment for PCOS patients is still a matter of controversy. Despite producing more follicles and more oocytes than other women undergoing controlled ovarian hyperstimulation during an IVF cycle, women with PCOS have comparable or lower pregnancy rates. Additionally women with PCOS patients undergoing IVF have a higher risk of developing ovarian hyperstimulation syndrome (OHSS), which may be aggravated by pregnancy after an embryo transfer in a fresh cycle. Further women with PCOS are thought to have higher rates of later pregnancy complications including spontaneous abortion, pre-eclampsia, and preterm labor that may be related to impaired implantation in the superovulated endometrium. We propose a randomized clinical trial of elective embryo cryopreservation followed by a programmed cycle of endometrial preparation and frozen embryo transfer (FET) compared to fresh embryo transfer in women with PCOS undergoing in vitro fertilization (IVF).

This study will examine the impact of manual physical therapy on endocrine function in women diagnosed as being infertile due to elevated follicle stimulating hormone (FSH) levels (10 mIU/mL or higher) on days 2-5 of their menstrual cycle. It is hypothesized that the manual physical therapy will decrease FSH levels.

The purpose of this study is to determine whether edometrial local injury improves the outcome of embryo transfer,and to find out more evidence about the time of trauma,the way of intervention,and the possible mechanism.

Poor ovarian response (POR) is one of the major therapeutic challenges in in vitro fertilization. Several therapeutic approaches for POR have been explored; yet, a single effective strategy has not yet been established. Recently, a live birth was reported after ovarian cortex fragmentation and in vitro disruption of the Hippo signaling pathway and activation of Akt signaling. During IVM procedure increased mechanical stimulation of the ovarian cortex takes place. , with the consequent disruption of the Hippo signaling pathway. Our aim is to investigate whether the mechanical manipulation and triggering of ovarian cortex caused by IVM can cause ovarian follicular activation and recruitment by the mechanisms mentioned above. Thus stimulation in the following regular IVF cycle will result in improved ovarian response and increased oocytes yield
