Filter by:Prospective, non-comparative, multi-centre, multi-country, observational post-authorization study, to correlate predictive factors with number of oocytes in relation to the gonadotropin dose administered using a new r-hFSH product (Bemfola®) for ovarian stimulation and GnRH-antagonists for pituitary suppression
Non-comparative, observational, ambispective post-authorisation study (EPA-SP).
The goal of this project is to identify autocrine, paracrine and endocrine factors which are associated with intercycle variation in cyclical follicle recruitment. Patients will be monitored in a natural cycle, a stimulated cycle and a follow up. In the stimulated cycle patients will be randomized to co-treatment with aromatase inhibitor or placebo during ovarian stimulation.
Corticosteroids have been indicated to treat men with ASAs. Although many studies have confirmed the clinical therapeutic significance of corticosteroids in the treatment of men with ASAs, other studies have not found a therapeutic significance for corticosteroids in the treatment of men with ASAs. Moreover, although some reports have shown high fertilization and conception rates in couples when husbands did not have ASAs, other reports have shown that ASAs do not have a negative effect on fertilization and conception rates. These contradictory results have left the therapeutic effect of corticosteroids in men with ASA in continuing controversy. This controversy is also extended to include the usefulness of assisted reproductive technology (ART) in the treatment of patients with ASAs. In this regard, although some studies have shown that the pregnancy rate following in vitro fertilization (IVF) or intracellular sperm injection (ICSI) were similar in men with or without ASA or did not associate with ASA, others reported the superiority of ICSI over IVF and intrauterine insemination over natural intercourse in men with ASAs. It is possible that some patients with ASAs also have an additional problem(s) related to sperm binding to the oolemma and fusion into the ovum as well as sperm head decondensation. The latter condition may negatively influence or mask the clinical significance of corticosteroids on pregnancy rates in patients with ASAs. Some patients might not have benefited from corticosteroids and conventional IVF treatments due to the impaired sperm fusogenic capacity in addition to ASAs. Human sperm penetration assay (SPA), of the hamster oocyte free from zona pellucida, is a sensitive tool that can address such potential impairment of sperm binding with the oolemma and fusion into the oocyte as well as sperm head decondensation. Males with poor SPA results benefit from ICSI whereas those with good SPA results can still benefit from conventional IVF. The present study was therefore conducted to address the therapeutic usefulness of a corticosteroid named prednisolone in the treatment of immunologically infertile men undergoing IVF or ICSI determined by SPA.
AME is a non-interventional, prospective, longitudinal and multicenter study. This study aims to measure the relationship between antimüllerian hormone serum level (AMH), as measured by a fully automated assay and the initial dose of Menopur® HP-hMG 600 IU/mL prescribed for infertile women undergoing their first IVF/ICSI cycle in the current practice.
Men are recruited to collect seminal plasma samples and serum samples from men with azoospermia, men receiving medical treatment of infertility and men attending semen analysis. MicroRNA (miRNA) and PiWi-interacting RNA (piRNA) are analyzed for all of the groups to find potential differences. Steroid hormones are analyzed by liquid chromatography-tandem mass spectrometry.
Testes of men with non-obstructive azoospermia (NOA) are imaged using MRI to find potential differences depending on the outcome, ie. sperm recovery in consequent microdissection testicular sperm extraction (MD-TESE).
This study involves research, and the purpose of this study is to evaluate live birth rates among couples who are treated by Natural procreative technology, (NPT) for infertility and miscarriage. Comparisons will be made to those declining NPT treatment, waiting for NPT treatment, receiving other treatment, or stopping treatment. The investigator seeks to document specific pregnancy rates for different factors such as age and type of infertility diagnosis. Investigators will also assess characteristics of environmental exposures that may be associated with infertility. Couples will be followed for up to three years, regardless of when they begin NPT treatment, or whether they continue treatment. Data from all couples will be useful for this study, regardless of their individual circumstances or actual treatment.
During this study, patients will undergo a routine in vitro fertilization cycle as they would otherwise if not participating in the study. After eggs have been fertilized they will be cultured as usual until day 3 of embryo development. On day 3 of development, the embryologist will randomize half of the embryos to be cultured in 2% oxygen concentration and the other half at 5%, which is currently the standard of care. All other embryological care procedures will remain the same. On day 5 or 6 of embryo development, the embryos will be evaluated and each blastocyst stage embryo will be recorded. The primary outcome will be the blastulation rate (or percentage of embryos that reach the blastocyst stage).
During in vitro fertilisation (IVF) treatment, women receive hormone stimulation with gonadotropins to induce growth of several ovarian follicles. Selecting the optimal dosage of gonadotropin is important to avoid maturation of too few or too many follicles, which may impair the chances of treatment success, lead to treatment cancellation, or serious side effects. Motivated by the lack of standardised procedures to estimate the optimal dosage of gonadotropins, a patient-specific test has been developed to predict the optimal hormone dosage. By measuring internalisation of gonadotropin by the patient's monocytes isolated form the peripheral blood ex vivo, the Gonadotropin Removal Test determines whether a patient needs increased or reduced hormon doses. In this clinical study the investigators compare deviation from optimal outcome at oocyte pick-up day in two patient groups. Optimal outcome of stimulation is defined as 10 oocytes collected in the group of patients matching the inclusion criteria of the study. The control group receives starting hormone dosage assigned by the clinician according to standard clinical procedures. The intervention group receives starting hormone dosage adjusted according to the results of the Gonadotropin Removal Test.
