Double Stimulation Followed by a Fresh Embryo Transfer

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.

Evaluation of Matrix Metalloproteinase 8 Salivary Test for Diagnosis of Periodontitis

Despite the great progress in understanding the causes of infertility, the reason for the failure of pregnancy has not been discovered among 25% of infertile couples. Some studies have shown the negative impact of periodontal disease on the reproductive potential of women. It is known that there is an elevated level of matrix metalloproteinase 8 (MMP8) in the gingival fluid of patients with periodontitis. It is possible to establish a fast diagnosis of periodontitis by using a non-invasive assay based on monoclonal antibodies to two epitopes of MMP-8. The goal of the research is to use the above described assay in order to compare the level of MMP8 in the gingival fluid of infertile patients with the control group of fertile women, depending on the existence of periodontal disease. It is expected to find significantly higher values of MMP8 in infertile patients in relation to the fertile patient with/without periodontitis. The prompt treatment of periodontitis in preconception care of this group of women could have a significant impact on the improvement of fertility and ability to achieve pregnancy.

SU Versus GD for Sperm Preparation in IUI

Intrauterine insemination (IUI) is the first-line treatment for couples with unexplained and mild male factor infertility. The result of IUI depends on many factors including the sperm preparation techniques. Swim-up (SU) and Density Gradient (DG) are the two most commonly used techniques in sperm preparation for IUI. There is discussion about the effectiveness of these two techniques for IUI outcomes. The effectiveness of SU and DG methods on IUI success rate is not clearly understood and is controversial. This multicenter, randomized controlled trial will be conducted to determine which method (DG or SU) is better for IUI treatment.

The LUTEAL Trial: Luteal Stimulation vs. Estrogen Priming Protocol

Ovarian reserve defines the quantity and quality of the ovarian primordial follicular pool. Diminished ovarian reserve (DOR) indicates a reduction in the quantity of ovarian follicular pool to less than expected for age. It is an important cause of infertility in many couples. To date, there is no clear consensus in the literature on the definition of diminished ovarian reserve, and it is unclear whether low oocyte yield results from an abnormal atresia rate of the follicle pool, or from a lower follicle pool at birth or whether it can just occur as a normal variation in the population. The ovarian response to controlled ovarian stimulation with gonadotropins (for example, for in vitro fertilization) is largely determined by the ovarian reserve, and there are numerous different ovarian stimulation protocols that are employed to try and increase the oocyte yield of a particular cycle. There is no consensus on which, if any, of these protocols are superior and preferred for patient with DOR. Luteal gonadotropin stimulation is a protocol of controlled ovarian stimulation (COS) for use in assisted reproductive technologies (ART) that has emerged over the past decade as an acceptable alternative to the classic follicular gonadotropin stimulation. The luteal estradiol patch protocol was introduced in 2005 in patients with poor response to controlled ovarian stimulation (COS) and to address the phenomenon of early follicle recruitment in patients with diminished ovarian reserve (DOR). Luteal gonadotropin stimulation can potentially achieve the same effect by initiating follicular recruitment for IVF prior to the body's own premature recruitment. Our hypothesis is that the luteal stimulation protocol and estradiol priming protocol are equivalent with regard to the outcome of number of mature oocytes retrieved. Patients who will be undergoing controlled ovarian stimulation and who have a diagnosis of diminished ovarian reserve will be considered for this trial, and enrolled if meeting all inclusion and no exclusion criteria.

Detection of SARS-CoV-2 in Follicular Fluid and Cumulus-oocyte-complexes in COVID-19 Patients

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.
