Active clinical trials for "Infertility"

Infertility has important repercussions for couples in their emotional and sexual lives; the same is true of Assisted Procreation, which has an impact on the daily life of couples and a cost to society. Thus, fertility disorders are frequently associated with sexual dysfunction in both women and men (Khademi et al., 2008). In couples with male infertility, men have higher sexual dysfunction scores than couples with infertility without male aetiology (Smith et al., 2009). To study the evolution of the sexual quality of life of infertile men before and after knowing their spermatic parameters

to determine the most suitable time for administration of (human chorionic gonadotropin )hCG prior to intrauterine insemination (IUI) to optimize pregnancy outcome and to have the best success rates so the cases divided in to four groups according to the time of hCG administration .

This is a prospective study comparing vaginal and endometrial biomarkers and the trophoblast spheroid attachment rate in women with fertility problems before and after taking Vitamin D for 8 weeks.

With the development of assisted reproductive technology (ART), more and more infertile women are obtaining their offspring through assisted reproductive technology. However, a growing number of national and international studies have shown that infertility patients are prone to negative emotions such as anxiety and depression during ART treatment, which not only affects their physical and mental health, but also affects the embryo implantation rate and pregnancy rate of ART. The purpose of this study is to investigate the stress faced by participants undergoing ART with different cycles and to further investigate its impact on pregnancy outcomes.

All patients will undergo in vitro fertilization. Serum 25 (OH) D samples will be collected within1 week before oocyte retrieval. Whole blood specimens will be collected in serum separator tubes using acceptable medical techniques to avoid hemolysis. Ultrasound guided fresh embryo transfer will be performed on day 5 after fertilization. clinical pregnancy will be confirmed by observation of intrauterine sac visible on ultrasound performed 4-5 weeks after embryo transfer.

Normal testicular hormonal and spermatogenic function depends not only on the testis itself, but also on the integrity of the hypothalamus and anterior pituitary. Systemic diseases has been shown to influence male gonadal function in variety of ways, leading to reduced libido, erectile impotence, infertility, osteoporosis, and decreased physical stamina and muscle mass. The effect of systemic diseases may occur directly at the testicular level: reduced Leydig cell function will lead to androgen deficiency, while diseases affecting Spermatogenesis may lead to infertility. Alternatively, acute and chronic illness may interfere with the hypothalamic-pituitary axis and lead to reduced testicular function.

Infertility or infertility affects about 15% of couples of reproductive age. It is estimated that 80 million people around the world suffer from this problem. Assisted reproduction techniques (ART) use culture media (during in vitro fertilization or early embryo development) with protein sources that are very different from natural sources. This media could produce an added stress to the gametes and embryos that could cause epigenetic alterations and health effects during adult life. Our working hypothesis is based on studies in animal models (pig and cow), in which it was observed that the culture media with reproductive fluids used as additives instead of conventional sources of proteins (such as serum albumin) , produce embryos with an epigenetic profile closer to that of embryos generated in the maternal oviduct. Moreover, with these fluids, blastocysts obtained have a greater number of cells and hatchability than those produced with serum albumin alone. Therefore, the University of Murcia, with an extensive experience in this area, and the IVI Murcia (Valencian Infertility Institute) research team have come together to launch this research project in order to determine the advantages of the use of human reproductive fluids as additives in embryonic culture media. To do this, 2 specific objectives are proposed,: Creation of the first collection of human uterine fluid samples for Assisted Reproduction use. To evaluate the use of uterine fluid as a media supplement in the culture media for assisted reproduction techniques, by evaluating embryo quality cultured with autologous fluid from voluntary patients (autologous culture) This achievement would allow us the development of protocols in the nearest ART physiological conditions which represent not only a technical challenge but a biomedical responsibility that must be addressed to prevent future diseases of the offspring.

Basic and clinical research is revealing that various noncoding and small RNAs play important and diverse roles in germ cell development and quality, including X/Y silencing during meiosis, gene regulation, DNA damage responses, and protection of the genome against transposable elements. Indeed, mammalian germ cells are known to harbor multiple small RNA species, including small interfering RNAs (siRNA), microRNAs (miRNA), and germline- specific PIWI- interacting RNAs (piRNA). However, their mechanistic roles in gametogenesis and human infertility are largely uncharacterized. The goal of this study is to elucidate the role of small RNA pathways in the events that give rise to viable euploid gametes. Four projects and three cores are included in this study.

Our infertility unit has started a clinic for women with rheumatological diseases. those women are prone to infertility problems and it might be due to their illness or cytotoxic treatment . In our study we are going to observe the effect of their disease on ovarian reserve. we will assess it by using intravaginal sonography and blood test such as hormonal profile and anti-mullerian hormone (AMH).

The study will collect the clinical and biological data of the patients, the investigators could further analyse and identify the risk factors and optimize clinical treatment method. Besides, population-based healthy people with informed consent are also collected.
