Active clinical trials for "Infertility"

This goal of this study is to evaluate the outcomes from in vitro fertilization cycles where a 450 IU daily dose of gonadotropins is administered compared to those where a 600 IU daily dose is administered for women who are at risk of a poor ovarian response in order to determine if one dose or the other results in improved cycle outcomes.

This is a comparison of pregnancy achievement between two GnRH antagonist protocols which differ in the timing of GnRH antagonist initiation.

The goal of this research study is to compare the pregnancy rates for two different types of progesterone supplementation after in-vitro fertilization (IVF).

During IVF treatment, acupuncture at the time of embryo transfer may improve the pregnancy rate. This study aims to compare IVF pregnancy between two groups of patients that received either acupuncture or sham acupuncture (placebo)around embryo transfer

The purpose of the present study is to analyse prospectively if highly purified hMG compared with increased dose of clomiphene citrate has different outcomes in folliculogenesis in ovulation induction cycles.

The purpose of this study is to determine whether the administration of an analogue of gonadotropin-releasing hormone (GnRH) during the three months prior to the performing of an IVF may improve the response to ovarian stimulation, implantation rate and clinical pregnancy rate in patients with endometriosis/ endometriomas.

Clinical validation of the assisted reproductive technology (ART) treatment guidelines, which determine the optimal dose of recombinant human follicle stimulating hormone (r-hFSH) based on subject baseline characteristics/predictors of ovarian response.

The primary objective of this study is to determine if the use of frozen surgical testicular sperm specimens for ICSI lead to different IVF outcomes when compared with the use of fresh surgical testicular sperm for ICSI.

Endometrial injury performed in a cycle preceding the one for embryo transfer is associated with an increased implantation and pregnancy rate when carried out during the month preceding that of ovulation induction and fresh embryo transfer. However, there is no evidence about the effect of this intervention on the transfer of cryopreserved embryos.

The objective is to evaluate the influence of chemotherapy, either for auto-immune disease, either for carcinologic disease, on clinical and biological markers of ovarian reserve, for young patients, with normal reproductive functions.
