Active clinical trials for "Infertility"

This study is designed to generate a comprehensive survey of the use on the market of the Anecova device within its intended indications according to the Instructions For Use. The Anecova Registry is part of the Anecova quality system, to enable the Post Marketing Surveillance and the Post Market Clinical Follow-up.

Objectives: Male factor infertility is poorly understood and our ability to evaluate the male contribution to a couple's infertility is very limited. The overarching goal of this project is to understand at the molecular level what functional activities in human sperm are required for successful fertilization leading to full term development. These findings will allow us to develop new methods to determine the impact of environmental exposures on sperm quality and male fertility. A sperm protein known as phospholipase C zeta (PLC zeta) initiates embryo development at fertilization. The primary objective of this study is to test the hypothesis that human PLC zeta activity correlates directly with the proportion of fertilized eggs that undergo early cleavage during an in vitro fertilization (IVF) cycle. Secondary objectives for the study are to generate preliminary data regarding the variability in sperm PLC zeta activity within and between individuals and to determine if there are clinical or laboratory correlates for sperm PLC zeta activity. Study population: The study population will consist of 178 infertile couples undergoing IVF procedures at Duke Fertility Center (DFC) from which we will obtain 154 evaluable couples for the study. Overall Design: An observational cohort study design will be used to assess the association of PLC zeta activity in the residual sperm from the sample used for an IVF cycle with the proportion of eggs per couple that undergo early cleavage during the same cycle. Infertile couples enrolling in an IVF treatment cycle at DFC will be approached for inclusion in the study. Consent will be obtained from both male and female partners, and historical medical information and information about their IVF cycle will be collected by chart review. Blood for isolation of serum and DNA will be collected only from the male partner for evaluation of hormone levels and genetic analyses related to infertility. On the day of the egg retrieval, residual sperm not needed for clinical purposes will be transported via courier to NIEHS. Sperm PLC zeta activity will be measured in the investigator's laboratory using an experimental bioassay. Sperm PLC zeta protein will be analyzed at the University of Massachusetts. Outcome Parameters: The primary outcome will be the proportion of embryos that undergo early cleavage. Secondary outcomes will include proportion of eggs fertilized, embryo development parameters, and p...

The investigators are going to compare embryo developmental rates of human eggs following freezing in two different freezing methods. The investigators are going to compare the pregnancy rates following transfer to patients as well. Null Hypothesis: The type of vitrification methodology used will not have an impact on the following: Survival rates Embryonic developmental rates Pregnancy and implantation rates.

This is a prospective, randomized clinical trial to compare the Global commercial single step media to 1) G-TL (Vitrolife), 2) Weill Cornell's single step and sequential steps media, which all support human embryo development in the laboratory using the Vitrolife Time-Lapse system. The main goal of the study is to identify the best culture medium for optimal embryo development.

The purpose of this retrospective observational study is to describe the treatment patterns with MENOPUR and to understand the clinical impact for patients that underwent infertility treatment under real-world setting. The primary objective is to describe the treatment patterns for the general population and for selected patient profiles.

Identify, by Lipidomics approaches, biochemical markers of fertility / infertility in sperm and seminal plasma linking the success or failure of the artificial insemination (IUI)

The main objective of this study is to describe the level of expression of the biological factors involved in the formation of adhesions (Transforming growth factor beta, Activin A, inhibin) at the time of a first diagnostic hysteroscopy among women with synechia, another intracavitary disease or no intracavitary disease.

One of the main repercussions of POI is infertility. When the diagnosis of POI is announced, the question of fertility is addressed and the patient is often directed towards egg donation or adoption when she has a parental project. However, there are cases of spontaneous pregnancies after diagnosis. This study was conducted to determine the proportion of patients with POI who were able to realize a parental project after diagnosis in the long term and by what means.

Retrospective study designed to evaluate outcomes in patients undergoing assisted reproduction. Some of them had thrombophilia, and part of them was treated with enoxaparin, started on the day of embryo transfer, and the other part not. Women without thrombophilia formed the control group.

To explore the relationship between maternal age and embryo implantation rate in patients undergoing assisted reproductive technology.
