Active clinical trials for "Infertility"

At present, there is no agreement on the effect of vitamin D level in serum and follicular fluid on the outcome of IVF-ET pregnancy. Most of these studies were based on the research of total 25 (OH) D, which have ignored that the biological activity of vitamin D molecule is not total 25 (OH) D, but free vitamin D or vitamin D bioavailable, and have flaws in methodology. This project intends to make a prospective cohort study with large sample, based on a complete methodology of total vitamin D and free vitamin D to measure maternal vitamin D levels in blood,to systematically study the effect of maternal vitamin D status on IVF - ET pregnancy outcome. This study is also the first to study the relationship between maternal vitamin D status and the outcome of IVF-ET pregnancy using a complete methodology.

The COVID-19 pandemic brought new challenges to our nationwide healthcare system, with rapid escalation of the number of affected individuals over a handful of weeks. From March 13, a first set of measures was taken to minimise the spread of the virus, which largely impacted societal and economical daily life. A view days later, on March 17, the country was put in "lockdown" and all non-urgent medical treatments were cancelled or postponed. As recommended by the major scientific fertility societies, all non-ivf fertility treatments were discontinued abruptly, whereas started ivf stimulations were continued until oocyte aspiration, where after a freeze-all strategy was applied. There is little information available for women aiming for pregnancy or embarking on assisted conception. Given the modelling of the pandemic, including the time to peak and subsequent tail, considerable delays in conception to substantially attenuate risk may be required, which will inevitably impact patients wellbeing and overall success rates. A questionnaire was developed to explore patients perspectives on different aspects of their fertility treatment during the COVID-19 pandemic. The questionnaire contains the following sections: demographic variables; questions regarding the fertility history of the respondent; questions regarding the impact of fertility treatment cancellation / postponing fertility treatment during COVID-19 on their life, psychological wellbeing and relationship; questions regarding continuing medical treatment on their own, or seeking treatment elsewhere; questions regarding the satisfaction of measures taken by their fertility center regarding the COVID-19 pandemic; questions regarding expectations of further treatments, with focus on safety issues related to the COVID-19 pandemic. Eligible patients will be selected electronically from our database and digital agenda. After selection, patients will be contacted via email to participate. Two reminders will be send in case the questionnaire is not filled out: a first reminder after one week, a second reminder after two weeks.

Evaluation of endometrial receptivity is a crucial step in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) programs. Using "Omic technologies", such as transcriptomic and proteomic analyses, the investigators previously identified a specific molecular signature of human endometrial receptivity during the embryo implantation window. After validation of this signature in fertile women and in an ex vivo model (i.e., stromal and epithelial endometrium cells),the investigatorsdeveloped a diagnostic tool called Win-Test (Window Implantation Test) to evaluate the expression level of a set of endometrial receptivity-specific genes during the implantation window by quantitative RT-PCR. Based on their expression, each endometrial biopsy sample can be classified as receptive, partially receptive or non-receptive. Then, after the identification of the right cycle day within the implantation window where endometrium is considered as receptive, a customized timing for embryo transfer with respect of the synchronization of the embryo-maternal dialogue must be performed. A prospective study to validate the relevance of the Win-Test, is a necessary step to gauge its effectiveness. In this objective, patients with multiple implantation failures will be recruited. Embryo transfers were performed in double-arm: the intervention group had a customized timing of embryo transfer according to the Win-Test strategy and recommendation, the control group had their embryos transferred in a classical timing. Pregnancy and live birth rates (LBR) were compared between groups.

The association between serum progesterone (P) levels, measured on the day of ovulation trigger, and the outcome of in vitro fertilization cycles, has been one of the major controversies in the field of ovarian stimulation endocrinology. This is a single-center retrospective cohort study. Study duration period is from January 2012 to December 2016. All fresh embryo transfer (ET) both at cleavage stage and blastocyst stage, performed in Humanitas Fertility Center during the study period, were included.

This is a prospective study to assess the long term benefits and outcomes of the existing oocyte cryopreservation methods for fertility preservation in women with a potential medical or non medical risk of loss of fertility

French, non-interventional, retrospective, multicentric analysis of patients who have undergone a controlled ovarian stimulation (COS) for in-vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI). The main objective is to determine the cumulative live birth rate with highly purified menotropin (HP-hMG) which is defined as the occurrence of live birth per started COS, further to transfer of fresh and frozen embryos generated from the same COS.
