Active clinical trials for "Infertility"

Comparative study to determine whether several fertility monitoring products - the DuoFertility monitor, the LadyComp/Babycomp monitor and Clearblue Ovulation tests - are substantially equivalent in performance, and secondarily to determine the appropriateness of labeling information for the DuoFertility monitor.

The purpose of this study is to assess the feasibility of conducting an Internet-based prospective pregnancy study with preconception enrollment with women completing daily journals for up to 12 months while trying to conceive and weekly through pregnancy if it occurs.

In men presenting sperm alterations, the selection of genetically undamaged spermatozoa need to be improved in order to increase the success of assisted reproduction treatments. The aim of this study is to determine whether the presence of sperm head vacuoles is associated with sperm DNA alterations.

This is a prospective randomized trial comparing the outcome in women undergoing IVF/ICSI when taking their gonadotropin dosage in the morning (am) or evening (pm).

Evaluation of embryo quality in the fresh cycle as a predictor of outcome from frozen embryo transfer.

Ultrasound (US) guided embryo transfer (ET) appears to improve pregnancy outcomes in IVF-ET. Most reports are done using a transabdominal (TAS) approach, in contrast to a transvaginal ultrasound (TVS) which does not require a full bladder. We sought to determine if either approach was better with respect to clinical outcomes.

The overall hypothesis to be tested is: women with the molecular phenotype of highly skewed X chromosome inactivation are at increased risk of spontaneous abortion.

Recent evidence suggests a decline in fertility of persons living with HIV (PLWH) (delayed pregnancies, sponteanous abortions, especially when patients receive an antiretroviral therapy, early menopause, amenorrhea and anovulatory cycles) with a possible decrease in ovarian reserve. However, indications of fertility preservation by freezing oocytes are nevertheless not clearly identified. The objective of this study is to evaluate the ovarian reserve before and after the implementation of antiretroviral treatment in PLWH for whom the diagnosis of HIV has just been made.

The purpose of this research project is to determine whether or not the directional movement of spermatozoa is influenced by a pH gradient by examining spermatozoa in vitro.

To investigate prospectively whether embryos with abnormal cleaving pattern have different oxidative parameters from normally cleaving embryos, and to analyze whether these parameters have an association with demographic, laboratory and clinical parameters including treatment outcome.
