Active clinical trials for "Infertility"

The Reproductive Medicine Network (RMN) is a nationwide cooperative network of 7 clinical sites and a data coordination center, and is sponsored in 5 year increments by The Eunice Kennedy Shriver National Institute for Child Health and Human Development (NICHD). The RMN is charged with designing, implementing and publishing high quality clinical research in reproductive medicine. It has been in existence for over 15 years and has performed several seminal clinical trials that have fundamentally changed clinical practice in this field. In addition, many worthy ancillary protocols have been generated and published. It is this latter fact, as well as the continued interest by investigators both inside and outside the RMN for access to DNA or serum samples from the previously performed trials, that has motivated the present investigators to proactively begin a biologic samples repository from the ongoing and pending RMN clinical trials. Ideally, this repository would allow investigators to seamlessly access trial samples for many years into the future, and thus greatly amplify the use of resources and the impact of the RMN.

The purpose of this study is to demonstrate that the Eeva System may be used to identify embryos on Day 2 that are most likely to form blastocysts.

The study will involve up to 30 pairs of male and female sexually intimate partners who are carriers for a genetic disease (e.g Sickle Cell Disease or Thalassemia) and at high risk of transmitting the gene. The female partner will be superovulated to mature multiple oocytes which can be fertilized, inseminated with her partner's sperm through intra-uterine insemination (IUI). Four to six days after IUI, the female partner will undergo a non-surgical uterine lavage procedure to recover preimplantation embryos.

Records of women who had in vitro fertilization (IVF) or intra-cytoplasmic sperm injection (ICSI) in Dar AlTeb sub-fertility center will be reviewed and the follicular sensitivity index (FSI) will be calculated and correlated with pregnancy.

Chronic endometritis is a persistent inflammation of the endometrium. Chronic endometritis is asymptomatic or little symptomatic. Sometimes, patient with chronic endometritis can have genital bleeding, pelvic chronic pain, pain during sexual relations, persistent vaginal white loosing. The hysteroscopy can detect the presence or absence of chronic endometritis. Some studies showed that the endometritis could have an impact on the embryo implantation and could explain recurrent miscarriages or repeated embryo implantation failures. The goal of this study is to evaluate the frequency of the chronic endometritis in patients with recurrent miscarriages or repeated embryo implantation failures

This post-marketing, multi-center prospective study will be conducted in a open-label, non-interventional setting, for women seeking fertility treatment and will describe morphokinetic de-selection parameters in human embryos.

To determine in women undergoing IVF who are at high risk of multiple births (>35%), as calculated by the application of a predictive model - IVFsingleTM, if single embryo transfer will lead to both comparable clinical pregnancy rate (CPR) and other secondary outcomes such as live birth rate (LBR) and cumulative live birth rate (cLBR) in comparison to DET while reducing the incidence of multiple births (a secondary outcome measure).

The aim of this study was to assess meiotic recombination in primary spermatocytes, synaptonemal complex length and the correlation with chromosomal abnormalities in testicular spermatozoa from infertile men with idiopathic non-obstructive azoospermia (NOA).

Evaluation of ovarian function by a questionnaire and by medical file analysis of women and girls who underwent ovarian cortex cryopreservation for fertility preservation between 1997 an 2013 in the investigators' institution in order to evaluate their residual ovarian function. A second part of the questionnaire concerns these women's satisfaction regarding the procedure.

100 patients aged 21-40 years old, diagnosed as primary or secondary infertility . These patients are then assigned to receive fertility treatment (ovulation induction, ICSI, intrauterine insemination and IVF). They undergo a 3D vaginal ultrasound before treatment to measure the junctional zone thickness and followed up after treatment to determine the rate of implantation.
