Active clinical trials for "Infertility"

In this study, we aimed to assess the cervicovaginal environment (pH, Nugent score, soluble immune factors and bacterial profile) in women with reproductive failure because of either repetitive abortion or infertility of unknown origin and compare it to that of healthy fertile women. The second objective was to evaluate the ability of Lactobacillus salivarius CECT5713 to modulate such parameters and to increase pregnancy rates in women with reproductive failure. The administration of L. salivarius CECT5713 (~9 log10 colony-forming units (CFU)/day) for 6 months or until a diagnosis of pregnancy to women with reproductive failure resulted in an overall successful (term) pregnancy rate of 56%.

The study evaluated the effect of serum relaxin and follicular fluid levels on the number and quality of oocytes, fertilization, the number and quality of the embryos in IVF protocols.

Vienna Consensus has identified 10% damage rate after ICSI as a competency value. Despite the highest quality embryologists doing ICSI, degeneration sometimes occurs due to oocyte factors such as the fragile membrane, etc. Cytochalasin D serves to facilitate spindle or pronuclear transfer procedures helping to reduce the damage rate with no harm reported. Using Cytochalasin D during ICSI could serve to rescue some oocytes from the degeneration allowing for more chances of viable zygotes.

The cumulus-corona-oocyte complex (COCs) surrounds each oocyte and must be removed prior to intracytoplasmic sperm injection (ICSI). This is traditionally achieved with a bovine-derived hyaluronidase followed by mechanical denudation through pipetting. A human recombinant hyaluronidase (Cumulase) has been developed to circumvent the problems and concerns associated with the animal origin and lack of purity of the bovine-derived form of the enzyme. whether cumulase offers a higher chance for success after ICSI for women with 8 COCs or lower remains an open question.

The pH stability during human gamete handling for intracytoplasmic sperm injection (ICSI) is physiologically sound. As the pH change for bicarbonate-buffered medium, scientists assumed whether the use of HEPES or MOPS buffered medium would provide more stable pH, thereby better outcomes. However, the oil use and time frame outside the incubators have not been accounted for. This study is to evaluate the use of HEPES buffered medium compared with the bicarbonate-buffered medium on ICSI outcomes.

Background: In women, unexplained infertility has been associated with a range of cellular and molecular defects in the endometrium, adverse immune responses and immunological factors. Natural killer (NK) cells are included as they constitute the most abundant leukocyte population in the decidua. While decidua NK cells were extensively investigated, the study of endometrial eNK cells still lacks comprehensive researches. The reduction in eNK frequency has been associated with infertility status, in particular in the presence of a concomitant herpesvirus viremia. Since herpesviruses use as immune-escape HLA-G and HLA-E molecules, that are immune-inhibitory and important for a correct placentation, they could represent infertility co-factors. Aims: Since lack of an accurate diagnosis in reproductive medicine leads to treatment failure, this proposal focuses on eNK cell characterization as a diagnostic factor for unexplained women infertility. We will evaluate also co-factors, taking into consideration herpesvirus infection and HLA-G and HLA-E expression. Methods: Peripheral blood and endometrial NK cells will be immune-phenotyped and cell count and activation status (CD107a, IL-6, IL-10, IL-17) will be correlated with infertility condition. The implication of herpesvirus will be evaluated by DNA from peripheral blood and endometrial flushing samples analysis by HSV-1, HSV-2, EBV, CMV, HHV-6, HHV-7, VZV and HHV-8 specific primers an PCR technique. HLA-G and HLA-E expression will be analyzed in peripheral blood and endometrial environment by flow cytometry and ELISA tests and correlated by NK cell expression of their receptors (KIRs, LILRB1/2, NKG2A). Expected results: On the basis of our preliminary results, we expect to identify NK cells as prognostic marker for primary unexplained infertility, with herpesvirus infection and HLA-G and HLA-E expression as co-factors. These data will be of importance in the management of infertile women.

As Israel is the first country to widely vaccinate its population using the mRNA vaccine against COVID-19, evaluating its influence on ovarian reserve is essential .

The purpose of this study is to determine if embryo culture under a single CO2 setting improves blastocyst formation rate.
