Active clinical trials for "Infertility"

The aim of the present study is to determine the effect of follicular flushing on the ongoing pregnancy rate in patients who developed four or fewer follicles of 14mm following standard ovarian stimulation for IVF.

A randomised, crossover, multicentre, national, clinical trial comparing the efficacy of corifollitropin alfa versus daily recombinant FSH and HMG in the controlled ovarian stimulation of women with a poor ovarian response undergoing IVF treatments. The main objective of this study is comparing the number of oocytes obtained after the follicle puncture when using each of these two stimulation protocols. Only poor responders according to the Bologna criteria will be recruited for this trial. All participants will undergo two stimulation cycles to obtain and accumulate oocytes by vitrification. One of the cycles will be done with the corifollitropin alfa protocol and the other with daily rFSH and HMG, the order of application of these protocols will be randomised (crossover clinical trial) in each patient.

This is a randomized controlled trial to evaluate the effect of ramipril in stimulating and promoting sperm production in men with low sperm count. Ramipril is an Angiotensin Converting Enzyme Inhibitor (ACEI) currently used to treat high blood pressure. However, previous studies have shown that this class of medications can improve sperm parameters. The purpose of this study is to evaluate the efficacy of ramipril compared to placebo (Substance That is not known to have treatment effect), in improving sperm density in infertile men with documented low sperm count. This study will help us identify subjects that might benefit from treatment with this medication, and the effect it will have on sperm count, shape, and motility.

Nimodipine (Nimotop® Bayer Pharmaceuticals Corporation), unlike other calcium channel blockers is fat soluble and therefore is able to cross the blood-brain barrier1. Gonadotropin releasing hormone (GnRH) neurons are clustered in the hypothalamus and are dependent on calcium flux to release GnRH responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. In a natural menstrual cycle a spontaneous LH surge occurs mid-cycle which triggers ovulation. The investigators hypothesized that nimodipine, by blocking calcium channels, may effectively suppress the release of GnRH and consequently the natural LH surge. In this prospective double-blinded randomized study the investigators will evaluate the efficacy of nimodipine to inhibit the natural LH surge in women undergoing controlled ovarian stimulation (COS) and intrauterine insemination (IUI). Nimodipine, if successful, may represent an inexpensive oral medication as an alternative to the currently used GnRH agonists or GnRH antagonists in assisted reproductive technologies like IVF.

The purpose of this study is to evaluate the efficacy of intracutaneous sterile water injections (ISWI) for treatment of acute low back pain in patients presenting to the emergency department. The primary aim is to determine if ISWI provides pain relief for acute low back pain in the ED. The secondary aim is to evaluate whether ISWI provides improved patient satisfaction in the ED setting. The hypothesis is that ISWI will improve pain amongst patients presenting with acute low back pain to the ED.

This study evaluates the effect of single embryo transfer (SET) with and without array CGH for the evaluation of the complete chromosome complement of the blastocyst. Patients will be allocated at random into two groups. The control group will consist of patients in which one embryo will be replaced on day 5 based on morphological and developmental characteristics, and the other embryos reaching blastocyst stage will be vitrified. The test group will consist of patients undergoing embryo biopsy at the blastocyst stage (day 5 of development, embryo freezing, and analysis of the biopsied cells with a comprehensive chromosome analysis technique (array Comparative Genome hybridization or aCGH). Only a chromosomally normal blastocyst will be replaced in a thawed cycle. Inclusion and exclusion criteria are described in the study population section.

Sperm DNA fragmentation (SDF) serves as a marker for chromatin and DNA damage in sperm. Assessing sperm DNA integrity is crucial in male fertility evaluation since high levels of SDF are associated with a greater number of adverse reproductive outcomes, including an increased risk of miscarriage and birth defects. Recent research suggests that advanced paternal age (APA) may lead to DNA damage in sperm, however the precise age at which this risk becomes apparent has not yet been clearly defined, necessitating the identification of the point in time at which high SDF levels occur. With the help of this knowledge, male infertility can be diagnosed with greater accuracy, and infertile couples can receive appropriate care.

The use of machine learning techniques using an artificial intelligence tool is proposed to analyze clinical data to predict best possible IVF/ART outcomes. This tool has been utilized to accurately predict embryo quality here at Cornell. Utilizing this tool to assess objective clinical findings and predict outcomes of assisted reproductive techniques is sought, with the ultimate goal of an automated tool to reduce implicit physician bias. Within this goal, using this tool to objectively and accurately assess baseline ovarian reserve at the start of an ART cycle is proposed, using 3D sonography to image the ovary and artificial intelligence tool to objectively identify baseline antral follicle counts.

To evaluate the response of the endometrial lining after subcutaneous administration of the medication AMD3100. This medication mobilizes stem cells and will be used in a population of infertile women with a thin endometrium who are undergoing frozen-thawed embryo transfer. The investigators will assess associations between response to stem cell mobilization and pregnancy outcomes.

This exploratory study investigates fasting as a potential supportive therapy for infertility treatment in women undergoing in-vitro-fertilization (IVF) / intracystoplamsatic sperm injection (ICSI)
