Active clinical trials for "Infertility"

In vitro fertilization (IVF) is an assisted reproductive technique to achieve pregnancy in subfertile couples of which the average success rate is only 25%. Mild ovarian stimulation treatment yields less oocytes, has less adverse effects but has a comparable clinical outcome compared to conventional stimulation treatment. There is high inter- and intra person variability in ovarian response and fertility outcome parameters after stimulation treatment and little is known about explanatory variables herefore. Nutrition and in particular folate, or its synthetic derivative folic acid, is a B-vitamin which has been widely asssociated with reproductive outcome and subfertility. Therefore, in this study we aim to investigate the influence of preconception nutrition and folic acid use on ovarian response after mild/conventional stimulation treatment and to identify biomarkers in the follicular fluid which can indicate oocyte quality and other fertility outcomes.

For an efficient "egg banking" system, an equally efficient cryopreservation strategy that ensures the viability of the oocytes is required. Very recently, improved and new methods are yielding satisfactory results. In particular, vitrification is providing excellent results for both survival and clinical outcomes. However, to evaluate the over all out come there are other parameters to be considered. In this sense, capacity development of embryos generated after oocyte vitrification is a major factor when assessing the viability of vitrified oocytes. Accordingly, the evaluation of the capacity of vitrified oocytes to reach the blastocyst stage will be highly valuable to fully assess the effectiveness of the "egg banking" and its contribution to ovum donation programs. The aim of this study is to evaluate the developmental capacity of vitrified oocytes by their ability to reach the blastocyst stage. The study includes oocyte donation cycles conducted with vitrified versus fresh oocytes.

The purpose of this follow-up study is to collect the outcome and safety of FTET cycles after the embryos are cryopreserved in P06029 (NCT01144416). P06029 was a study in which a single injection of corifollitropin alfa (SCH 900962) was compared with daily recombinant follicle stimulating hormone (recFSH) injections in women aged 35 to 42 years undergoing controlled ovarian stimulation (COS) prior to in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).

The purpose of this study is to determine the best way to freeze eggs in order to preserve the fertility potential of young women.

Tobacco is a male infertility risk factor. Many studies comparing smokers to non-smokers have shown effects on spermatogenesis and the quality of the male gamete. In vitro fertilization success rates are decreased in smokers and in natural procreation the time required to conceive (excellent fertility indicator) seems to be lengthened in the smoker. The prospective study that the investigators propose to carry out would make it possible to know the time required for the repair of the sperm abnormalities and in particular the DNA of the gametes generated by the smoking.

Any drift in extracellular pH (pHe) from the intercellular pH (pHi) could alter the mechanism regulating transporters and exchangers through the plasma membrane. This could lead to difficulty in restoring the physiological level of pHi. The critical stages that lack robust mechanism of regulating the pHi are the denuded oocyte, early stage of fertilization or a thawed embryo. This, in turn, could lead to a significant effect of the perturbations on embryo development. Convincing evidence regarding the optimal pHe for culturing human embryo is, so far, scanty and mostly anecdotal. The embryo has been reported to have a compensatory mechanism to grow at pHe between 7.0-7.4. Others have recommended that embryo need a sequential pH to viably grow suggesting that the post-genomic activation stage needs a slightly alkaline range of pH. However, whether this holds true remains to be examined.

Involuntary childlessness is experienced as emotionally stressful, however psychosocial counseling is not always available on the spot. Aim of this RCT study is to examine the efficacy and acceptance of a psychological low-dose online intervention for couples in reproductive treatment.

The purpose of the study is to evaluate the safety and efficacy of nasal gonadotropins (Menopur) in women undergoing IVF. The purpose of this study is also to report and monitor any and all side effects of the nasal Menopur.

The purpose of this study is to determine if the utilization of the SPIKES protocol for delivering bad news is perceived to be more compassionate and effective than the current standard of care for IVF patients receiving negative pregnancy test results.

Ampoules (EIPICO PHARMA, EGYPT) and Treatment B REFERENCE Product Pregnyl 5000 I.U. Ampoules (Baxter Pharmaceutical Solutions for Organon, USA)
