Active clinical trials for "Infertility"

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.

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 .

The investigators will study the immune cell subpopulations in follicular fluid of patients undergoing In-Vitro Fertilization (IVF) treatment in our clinic. The investigators will corelate the presence of immature myeloid cells to the ovarian stimulation response as indicated by follicle stimulating hormone (FSH) and number of follicles or estradiol level developed on the day of human chorionic gonadotropin (hCG) administration.

Infertility affects approximately one in six couples1. In approximately one third of cases, there is no cause found as to why a couple are unable to conceive2. In order for natural pregnancy to occur, sperm must pass through the cervix (neck of the womb) and swim to the woman's Fallopian tubes so that fertilisation of one of the woman's eggs can occur. It is known that mid-cycle mucus at the cervix is essential for sperm to gain access to the uterus and tubes. There is evidence that the composition of this mucus in women may affect fertility but this area has not been studied well in recent years, partly because fertility treatments such as IVF bypass the cervix. Research in sheep and cows in UCD has shown interesting differences in the cervical mucus of fertile and infertile animals. It appears that the mucus not only helps sperm to get to the uterus but may also help the sperm to mature and be ready to fertilise an egg. This mucus may also help prevent bacteria and infection reaching the womb. In conjunction with colleagues in UCD, under the leadership of Professor S Carrington, the investigators would like to investigate some of the properties of human cervical mucus.The investigators propose to do this by taking samples of cervical mucus around the time of ovulation and also approximately one week later in fertile women and sub-fertile women. Then to monitor ovulation with an ultrasound scan (follicle tracking) of the woman's ovaries and urinary ovulation kits and take blood for oestrogen, progesterone, LH and FSH levels. The investigators wish to determine if there are differences between the mucus of these women and how it may impact on sperm function and on fertility.

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).

Male infertility is a multifactorial disease process with a number of potential contributive causes. Considering the majority of male infertility cases are due to deficient sperm production of unknown origin, environmental and nutritional factors must be evaluated. The purpose of this study is to evaluate the effects of 6 months antioxidant dietary complement (Conceptio) on sperm parameters (sperm count, motility and DNA fragmentation) in infertile men with oligoasthenozoospermia.

The importance of glucose in culture media on fertilization and embryo development is still controversial. Although it has been reported that glucose is essential for fertilization process and biosynthesis of membrane lipid and nucleic acids, comparatively high levels of glucose in culture media may cause developmental arrest of cleavage stage embryos. The aim of this retrospective study is to examine whether exposure of sibling oocytes to different concentrations of glucose in culture media has any further effect on IVF outcome.

Does group culture using micro-well group culture dishes improve human blastocyst development compared to single embryo culture?
