Study for Obtaining Mature Oocytes by in Vitro Maturation in Oocyte-donor Women
Female InfertilityIn vitro maturation (IVM) is a technique for obtaining potentially fertilizable oocytes from immature oocytes. An oocyte must be mature both nuclearly and cytoplasmically in order to be competent in the reproductive process. Nuclear maturation involves an oocyte in metaphase II stage and is easily evaluated for its morphology. However, cytoplasmic maturation can only be evaluated by in vitro fertilization of that oocyte A mature nuclear and cytoplasmic oocyte is one capable of producing a viable embryo. This study aims to fine-tune the in vitro maturation (IVM) technique to achieve nuclear mature oocytes, i.e., to mature the oocytes up to the metaphase II stage. In addition, an artificial oocyte activation (AOA) will be carried out to check the cytoplasmic maturation of the oocytes, avoiding the generation of potentially viable embryos. The aim of this study is to evaluate the response to the strategy stimulation with highly purified human menopausal gonadotropin (hMG-HP) administered for three days, in association with a standard methodology of in vitro oocyte maturation (IVM), to be performed on oocyte donors. The correct functioning of this IVM technique would mean a reduction in the costs of ovarian stimulation treatments, as lower doses and shorter stimulation times are required, which implies lower risks for women derived from the medication and less stress for them.
Intrauterine Insemination Predictor Factors
InfertilityMultiple studies have reported on the impact of factors such as female age, duration of infertility, type of infertility, hormone levels (i.e. AMH, FSH, estradiol, progesterone), use of different ovarian stimulation protocols, timing/induction of ovulation, number of pre-ovulatory follicles, endometrial thickness by the time of ovulation, sperm parameters (i.e. concentration, progressive motility, morphology, total motile sperm count [TMSC], inseminating motile count [IMC]) and sperm washing procedures. Also the influence of body mass index and smoking on IUI outcome have been studied before. However, results on the predictive value of these parameters remain highly contradictory. The aim of the study is to examine the value of different variables in the prediction of IUI success to develop a clinically useful predictive model of pregnancy and live birth.

A Lifestyle Intervention to Improve in Vitro Fertilization Results
SterilityPlacenta; Implantation3 moreEmbryo adhesion and placentation depend on tissue plasminogen activator (tPA)-mediated activation of brain-derived neurotrophic factor, vascular endothelial growth factor and other growth factors, formation of hemidesmosomes, and degradation of extracellular matrix and basement membrane, either directly or by activating matrix metalloproteinases. Since glucose and insulin stimulate release of a major tPA inhibitor by endothelial cells - plasminogen activator inhibitor (PAI)-1 - the investigators hypothesized that lifestyle interventions proven effective in maintaining glucose and insulin levels within the normal range would increase the take home baby rate in women undergoing assisted reproduction.
Psychosocial Intervention in Assisted Reproduction Treatments
Infertility PrimaryPsychosocial Stressor1 moreThe aim of the study was to evaluate and compare different strategies of psychosocial intervention for patients undergoing IVF treatment in a private fertility clinic. Recruited patients were assigned to one of three groups: group intervention, couple intervention or no intervention (control group). Three main variables were assessed: depression, anxiety and life quality.

RCT to Assess the Clinical Benefit of the ERA Test in Infertile Women at Their First IVF/ICSI Cycle...
InfertilityFemale1 moreEndometrial receptivity takes place in a self-limited period of time during the endometrial mid-secretory stage. This period, named as window of implantation (WOI), is modulated by molecular changes allowing embryo implantation to take place. It has been already demonstrated the existence of transcriptomic profiles that are characteristics of each endometrial phase: pre-receptive, receptive and post-receptive. 'Igenomix' group developed a molecular tool able to classify the endometrium based on its transcriptomic profile, the Endometrial Receptivity Analysis (ERA). This molecular tool analyses, by next generation sequencing (NGS), the expression of 248 genes related to implantation coupled to a computational predictor to identify the specific transcriptomic profile for each endometrial stage. This test has been applied at clinical level from 2010, helping to synchronize a viable embryo with a receptive endometrium through the personalized embryo transfer (pET). It aims to improve clinical implantation by personalizing, diagnosing, and synchronizing the endometrial factor. Our goal in this project is to investigate at what extent, if any, the analysis of the endometrial factor, at receptivity level, in patients at their first in vitro fertilization (IVF) cycle improves their clinical outcome through a personalized embryo transfer by the ERA test in comparison to embryo transfer(FET).
Progesterone Levels During Ovulation and Luteal Phase
InfertilityFemaleNatural cycles are evaluated during fertility treatments for different therapeutic options, like insemination (IUI), time intercourse (TI) or frozen-thawed embryo transfers (FET). Two possible protocols can be used for natural cycles, with or without hCG trigger. Usually, studies including natural cycles consider both options as equivalent, not considering the possible bias that the exogenous hCG (human chorionic gonadotrophin) might have. In this prospective study, Investigators aim to evaluate the differences in the hormonal profile during the ovulation when it occurs spontaneously vs triggered with a bolus of hCG.
