Filter by: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.
Non-urgent medical care, such as fertility treatments, has been massively postponed during the past weeks due to the COVID19 pandemic. The lockdown and the closure of IVF centers might cause anxiety and depression among infertile couples, who are already exposed to the distressing experience of infertility and for whom the wait for a baby already appears unending. Few data are available regarding the impact of SARS-CoV-2 on pregnant women and foetus, or on fertility. This study aims to assess the views of infertile couple regarding the potential risks of COVID during their fertility treatment and their personal experience of the COVID pandemic and their expectation for further treatment .
The major goal of controlled ovarian stimulation (COS) is to increase the number of oocytes harvested in order to result in the generation of a higher number of available embryos, extended embryo culture, embryo selection and finally providing higher cumulative live birth rates in infertile patients. Moreover, with the idea of the multiple waves of follicular production, we could start to take full advantage of the whole follicular cohort, and not only of the follicular wave. In the context of low prognosis women such as women with poor ovarian response where, the success rates are very low due to the low number of oocytes retrieved and consequently of viable embryos), Dual stimulation may be of great value as a tool to improve outcomes. The reported advantage of DuoStim is retrieved of more oocytes within a shorter time span, resulting in an increase in the probability of having transferable embryos increases, and theoretically reducing time to live birth as well as cycle cancellation.
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%.
This study is a comparison between the current standard practice of performing a diagnostic hysteroscopy and a relatively recently developed technology that is added to the standard diagnostic hysteroscopy. The aim of the study is to find out whether this newer technology has an advantage for the patient, in the form of anxiety and pain reduction.
Recently, the world was shaken awake by a pandemic caused by a novel coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). In most nations drastic isolation measures were taken to minimize the further spread of the Coronavirus Disease 2019 (COVID-19). Being the first pandemic sparked by a Coronavirus, little was known on COVID-19 and its implications on general health. Our understanding on the virus and its potential effects on health is growing. In Belgium, the situation is stabilizing, and doctors and healthcare workers are slowly recommencing routine work and consultations. As also fertility treatments were abruptly interrupted, many patients are in need to resume their treatment. The limited evidence of SARS-CoV-2 on pregnancy seems to be rather satisfying1, but practically nothing is known about the possible impact of an active SARS-CoV-2 infection on female gametes. Viral transmission occurs predominantly through respiratory droplets, but transmission to gametes cannot be ruled out. Since the onset of the pandemic, knowledge about the molecular details of SARS-CoV-2 infection rapidly grew. Coronaviruses are enveloped RNA viruses. For a virus to deliver their genome into the host cell, attachment and entrance into that cell is a crucial step. The coronavirus surface protein spike (S) mediates entry into target cells by binding to a cellular receptor and subsequent fusing of the viral envelope with a host cell membrane. The SARS-CoV-2-S protein (SARS-S) utilizes angiotensin-converting enzyme 2 (ACE2) as a receptor for host cell entry. Host proteases such as transmembrane serine protease 2 (TMPRSS2) are then needed to cleave the viral S protein, allow-ing permanent fusion of the viral and host cell membranes2. Expression of ACE2 and TMPRSS2 has been shown in testicular, uterine and placental cells. Based on available transcriptomic data, co-expression of ACE2 and TMPRSS2 is also seen on oocyte level, but the possible impact on reproduction is unknown. The BSG (basigin or CD147), a receptor on host cells, was also identified as a possible route for viral invasion.

This study will determine the rise of progesterone levels after human chorionic gonadotrophin (hCG) trigger in stimulated cycles IVF/ICSI
Objective: To study whether an administration of corifollitropin alpha modifies the follicular cohort, measured by Follicular Output Rate (FORT), compared to human menopausal gonadotropin (HMG), in infertile patients undergoing in vitro fertilisation (IVF). M/M: 306 infertile patients undergoing in vitro fertilisation (IVF). Ovarian stimulation protocol will be performed with a single dose of 100 μg (<60kg) or 150 μg (≥60kg) corifollitropin alpha in group 1 (n=147), and 150-300 IU/day human menopausal gonadotropin (HMG) according to age, antimullerian hormone (AMH) level and antral follicle count (AFC) in group 2 (n=150). Moreover, FORT will be calculated as the ratio of pre-ovulatory follicle (16-22 mm in diameter) count on day of HCG×100/small antral follicle (3-8 mm) count at baseline.
Saline infusion sonography (SIS) and hysteroscopy are commonly employed methods for uterine cavity evaluation. While hysteroscopy is regarded as the gold standard for diagnosis of intra-uterine pathology, it is not often used as an initial screening tool because of provider concerns about in-office tolerability, operating room costs, and use of anesthesia. The investigators aim to compare SIS and office hysteroscopy with respect to patient and provider satisfaction. Additionally, the investigators aim to assess the capability of office-based hysteroscopy to manage intra-uterine pathology at the time of diagnosis and reduce delays and supernumerary procedures.
