Active clinical trials for "Infertility"

The purpose of this study is to evaluate whether the addition of follicular flushing to the initial aspiration during oocyte retrieval increases the number of oocytes retrieved in women undergoing ovarian stimulation.

Women´s period comprises different hormonal stages, being one of them the stage for maximum receptivity and proper embryo implantation. This stage is named window of implantation (WOI), and is characterized by a specific molecular pattern than can be assessed by the Endometrial Receptivity Analysis (ERA® test), developed by Igenomix. Determining the WOI allows to schedule a personalized embryo transfer (pET) when the endometrium is most receptive for the implantation. The main objective of the present study is to improve our knowledge on the endometrial factor in an infertile population with previous implantation failures. To do so, a diagnosis of the endometrial receptivity to determine the WOI (ERA®) and the microbiome (EMMA®) of each participant will be performed, assessing its impact on deferred embryo transfers in terms of reproductive outcomes. Participants will follow their previously programmed IVF/ICSI treatment and, only when one embryo with no major anomalies is reported by PGT-A (Preimplantation Genetic Testing for Aneuploidies), they will be asked to attend to the specific study visit for endometrial fluid and biopsy samples collection. These samples will be used to determine the patient's WOI (ERA®) and endometrial microbiome (EMMA®). The results of neither of the tests will be disclosed to the patient or the doctor, being only used for the study purpose. After this visit, the patient will follow the pre-established schedule for an embryo transfer and pregnancy assessment.

The aim of this RCT is to compare differences in the efficacy and safety between cleavage-stage embryo transfer and blastocyst-stage embryo transfer in IVF/ICSI treatment cycle, taking into account of subsequent vitrified embryo transfers. Subjects with 3 or more transferrable cleavage embryos will be randomized to the cleavage-stage or blastocyst-stage embryos transfer group. The primary outcome is cumulative live birth rate (CLBR) per patient until the first live birth from one initiated oocyte retrieval cycle, calculated using outcomes from the first three embryo transfers within 1 year after randomization.

The study compares in a randomized controlled way two stimulation methods. One of these stimulation methods implements a new insight in ovarian follicular growth. If this novel method of stimulation proves to be as efficient as the classical stimulation protocols, there might be a dramatic reduction of the costs of the medical therapy in IVF, thus reducing also the overall IVf costs significantly.

Pregnancy rates fall dramatically in women after 35 years undergoing to IVF or ICSI. While ovarian aging obviously plays the major role in this phenomenon, over suppression of endogenous LH concentrations with GnRH agonists or antagonists-an integral part of standard IVF/ ICSI protocols-may also play a pivotal role. Assisted reproduction technology protocols using GnRH agonists have been considered as the standard protocol during the last two decades, but the use of GnRH antagonists offers the opportunity to control the endogenous LH surge in a rapid and more convenient way. LH plays a key role in the intermediate-late phases of folliculogenesis. The presence of receptors for LH in cumulus granulosa cells and its correlation with oocyte maturation has been demonstrated. Although ovarian stimulation is efficiently achieved in most cases by the administration of exogenous FSH alone, specific subgroups of women may benefit from LH activity supplementation during ovarian stimulation. Some authors have found improved outcome with LH activity supplementation in advanced reproductive age women. LH has a number of roles in follicular development, induction of ovulation, completion of meiosis I, early luteinization and the production of progesterone. The efficacy of recombinant human follicle-stimulating hormone (r-hFSH) for ovarian stimulation is well established however, the role of supplementary recombinant human luteinizing hormone (r-hLH) is less clear. Aim of the present study is to evaluate If adding rLH in the late phase of stimulation can benefit in some patient awith repeated implantation failure.

This study evaluated the effects of preoperative anxiety and dosage of anesthesia on IVF success. Half of participants according to the recorded Beck's Anxiety Inventory (BAI) score: a low-anxiety group, while the other half high-anxiety group.

The purpose of this study is to compare the effect of pre-IVF cycles treatment with and without DHEA(Dehydroepiandrosterone) on the ovarian reserve markers, the number of oocytes obtained and IVF(in vitro fertilization) outcomes of DOR(diminished ovarian reserve) patients and the expression of BMP-15(bone morphogenetic protein 15),GDF-9（growth differentiation factor 9) and IGF-I(insulin-like growth factors-1) in follicular fluid.

The Inovium Ovarian Rejuvenation Treatment is a PRP-based autologous treatment used in combination with a stimulated IVF sequence and Pre-Implantation Genetic Screening to treat infertility in women experiencing menopause, perimenopause, and premature ovarian failure.

the aim of the study is to compare between the step-up and conventional protocols in ovulation induction in infertile women with PCOS

This study evaluates the addition of collagen scaffold loaded with autologous bone marrow mononuclear cells(ABMNC) to Foley catheter balloon after hysteroscopic adhesiolysis in the treatment of severe asherman syndrome. Half of participants will receive collagen/ABMNC scaffold after hysteroscopic adhesiolysis, while the other half will receive Foley catheter balloon.
