Active clinical trials for "Infertility"

This study evaluates the addition of clomid to letrozole for the treatment of infertility in women with polycystic ovary syndrome. Half of the participants will receive letrozole and clomid in combination, while the other half will receive letrozole alone.

We would like to propose that it may be possible to use a solitary dose of Elonva (corifollitrophin alpha) as the sole gonadotrophin (FSH) stimulant for the vast majority of women undergoing IVF, assuming that it is possible that "coasting" (withholding short acting rFSH) from day 8 of the stimulation until trigger/ oocyte retrieval will still result in a significant number of mature oocytes being produced and an acceptable pregnancy rate.

To compare the effectiveness of freeze-all and subsequent frozen embryo transfer (freeze all protocol) with fresh embryo transfer (fresh ET).

The aim of the current study is to evaluate to effectiveness of sperm selection by using fertile chip in unexplained infertile couples on intracytoplasmic sperm injection (ICSI) cycles.

The effect of use of the growth hormone with antagonist protocol on the outcome of the IVF/ICSI cycles in poor responders.

Study if supporting luteal phase of high responder (high egg production or high Estradiol level) long Gn_Rh agonist protocol ICSI/IVF cycle by combined Estradiol and progesterone impairs or improves outcome in terms of pregnancy and implanation rates.

To test the hypothesis that adding estradiol (E2) to progesterone supplementation later in the luteal phase of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles, rather than earlier in the luteal phase, improves clinical pregnancy rates (PRs).

The purpose of the non-inferiority study is to evaluate the clinical efficacy and the safety of two different subcutaneous FSH preparations (Fostimon versus Gonal-F) for controlled ovarian hyperstimulation in a GnRH-antagonist cycle.

The chances to achieve pregnancy after retrieving >15 oocytes are not good, probably because of bad effect on the endometrium (uterine inner lining). Therefore, in most such cases the investigators prefer to freeze all embryos, and transfer in a thaw cycle. With the introduction of oocyte vitrification (very fast cooling) technology, a new option emerged: to freeze un-fertilized eggs, to be fertilized and used later in a thaw cycle. The purpose of this study is to compare the outcome of these two approaches.

Study of the treatment of infertility caused by recurrent intrauterine adhesions (IUA) by collagen scaffold loaded with umbilical cord derived mesenchymal stem cells (UC-MSCs) to provide clinical evidence of safety and effectiveness for the treatment of uterine infertility.
