Active clinical trials for "Infertility"

The purpose of the study is to determine whether or not stressful conditions such as ovum pick and awaiting Embryo Transfer is associated with significant increase in serum Prolactin (PRL) concentration in some normo-prolactinemic patients undergoing intracytoplasmatic sperm injection (ICSI) & possible effect on implantation & pregnancy rate.

IVF (in vitro fertilization) cycles fails more often than they succeed. Surprisingly very little effort is invested in defining the reasons for failure and possibly finding ways to improve the success on the next cycle. The investigators believe that the main reasons for failure are related to oocyte quality and indirectly to the follicle response for a particular patient. The investigators have developed a panel of biomarkers to assess the faulty follicular conditions leading to lower oocyte quality. Using these markers would indicate if a given cycle was characterized by over growth, over-luteinization, early or late trigger. Indeed our transcriptomics analysis has identified biomarkers of follicles still in their growth phase at trigger or follicles that have already begun luteinisation compare to follicle that are at the optimal level of differentiation. Measuring these biomarkers would allow making a better diagnostic for a given patient and potentially explaining reasons for failure. The system would also become adjustable to variable COS (control ovarian stimulation) and individual clinical practices. It is important to realize that this is applicable to almost all cycle failure and can be done on a pool of follicular cells when none of the oocytes obtained has led to a pregnancy. This does not resolve uterine problems but often these are caused by hormonal conditions established by the ovary or the ovarian treatment. This technology can be applied in all IVF clinics as no special equipment is required. It would be particularly valuable in clinics where a number of cycles is limited due to funding, or in clinic where a package of 3 cycles is proposed to the patient. The patient interest to have a custom treatment increases at each failing cycle as well as the doctors' interest to succeed. This technology is not clinically validated yet and would require a period of testing where participating clinics will collect the samples for a retrospective analysis (presence of biomarkers of follicular problems vs outcome) then in a prospective analysis where the diagnostic is used in a sub-set of patient to modulate the second/third cycle compared the outcome to patient with no diagnostic. The increase in pregnancy rate or cumulative pregnancy rate should reach a minimum of 10 and 25 % respectively to indicate a significant value.

This observational study aims the potential role of serum progesterone levels on the day of oocyte pick-up on the probability of pregnancy, in patients undergoing antagonist IVF cycles. There has been evidence, that increased serum levels of progesterone on triggering day are associated with a decreased probability of pregnancy after IVF. There is no study that investigate assocation between serum progesterone levels on the day of oocyte pick-up and IVF outcomes. This study will be the first in this case.

To collect data of clinical, biochemical and 3D-ultrasonographic parameters of a population of fertile women aged 18-55 in order to design a new algorithm able to predict ovarian age and to evaluate the reliability of a multimodal diagnostic evaluation of ovarian age in term of both reproductive prognosis and distance to menopause following the guidelines of the Standards for Reporting of Diagnostic Accuracy initiative (STARD)

Periodontal diseases and dental caries are initiated by a pathogenic biofilm, in a susceptible host, affecting the tooth periodontium and hard tissues. Its possible association with many biologic systems has been studied. In this study, researchers investigated association between oral health and female infertility, and what is the biological rationale for such relationship.

This study is focused on analysing the application of ultrasound scanning techniques as new biomarkers in reproductive medicine. Those biomarkers are based on the analysis of ultrasound texture in different areas of uterine tissue, using 2D/3D ultrasound scanning. Investigators will use the algorithm Text® to analyse the ultrasound texture of the endometrium and myometrium. The aim of the project is to study if it is possible to obtain measurable, objective and reproducible data in healthy volunteers which can be used to predict pregnancy and determine the best moment to perform embryo transfer in assisted reproductive technology (ART) cycles

Analysis of embryonic cell-free DNA (cfDNA) present in the spent culture media (SCM) is a non-invasive alternative for preimplantation genetic testing for aneuploidies (PGT-A) that avoids the technical challenges and limitations of biopsy. Initial studies investigating this non-invasive PGT-A (niPGT-A) method reported variable concordance between cfDNA in SCM and the trophectoderm sample (~ 30%-86%) and indicated a contribution from both the inner cell mass and trophectoderm to the cfDNA in SCM. This study aims to evaluate the use of the embryo culture medium as a source of genetic material for PGT-A and validate a niPGT-A protocol using cfDNA in SCM.

Many chemotherapy and radiation-containing regimens for cancer or prior to bone marrow transplantation can cause sterility in children and young adults. In addition, some human disease conditions (e.g., Klinefelter's) are associated with infertility. Semen cryopreservation is available as a fertility-preserving option for post pubertal boys and adult men, but many do not take advantage of this option due in part to lack of information, illness, and/or time constraints relative to their treatment plan. Currently, no fertility-preserving options are available for prepubescent boys who are not yet producing sperm. The primary objective of the proposed study is to 1) Optimize techniques for cryopreserving testicular tissue, 2) Assess malignant contamination in testicular tissues and 3) develop methods to enrich spermatogonial stem cells and remove malignant contamination from testicular tissue. In addition, this study will process and cryopreserve tissue and/or cells for participating patients as a resource for future elective procedures to attempt fertility restoration.

The woman fertility decrease with the age and there is a closely link with the ovarian reserve, the number of available eggs in the ovaries. Therefore, it is important to evaluate the ovarian reserve with specific marker to have a better prediction of the response of the in vitro fertilization treatment and to have a better rate of pregnancy. Until now, a lot of clinical criteria (age, duration of the infertility, number of antral follicles) and biological (FSH, Oestradiol, Inhibin B, EFFORT test, number of the eggs at the retrieval day) was suggested to help for the estimation of the ovarian reserve. Since couple of years, the anti-müllerian hormone (AMH) is recognize to be one of the best ovarian reserve marker, it corresponding the number of antral follicles, it is more sensitive and predictive. Moreover, during the In-Vitro Fertilization, the anti-müllerian hormone can provide the weak responds at the stimulation and the reverse, the risk of excessive responds (hyperstimulation). To choose the gonadotropin doses to administrate (stimulation ovarian hormone) during an In-Vitro Fertilization protocol, we need to know the anti-müllerian hormone dosage. However, if the anti-müllerian hormone is recognize to evaluate the quantity of available eggs in the ovaries, his role to determine the quality of these eggs still discussed. The goal of this study is to verify if the serum anti-müllerian hormone (blood) is a good indicator for the quality of the reserve ovarian evaluating the impact of anti-müllerian hormone rate on the pregnancy rate and implantation rate, during stimulate In-Vitro Fertilization protocol.

The aim of this project is to study the physiological role of the KiSS-1/GPR54 system in the granulosa cells of the human ovary.
