We present an overview of the current status of the European collaborative project PAEON. The challenge of PAEON is to provide specialists in reproductive medicine with a computerised model of the menstrual cycle under normal and various pathological conditions, which will allow them to get further insight in fertility dynamics. This model also enables the simulation of treatment protocols, whi...
background: determination of oocyte and embryo quality are one of the most important goals in ivf. anti-mullerian hormone (amh) is secreted by the ovarian granulosa cells into blood flow and follicular fluid. follicular fluid anti-mullerian hormone level is probably a marker of activity of granulose cells. objective: to evaluate whether high level of follicular fluid anti-mullerian hormone leve...
Background: Failed fertilization post ICSI has been mainly attributed to the sperm’s inability to induce oocyte activation. Phospholipase C Zeta (PLCζ) is considered to be a primary factor for the induction of oocyte activation. The aim of this study was to quantitatively assess the expression of PLCζ in globozoospermic or individuals with previous low or failed fertilization in comparison to f...
To investigate the mechanisms that account for the voltage dependence of fertilization and provide an electrical block to polyspermy, we studied cross-fertilizations between three species of amphibians having different degrees of voltage dependence. Anurans, such as the toad Bufo japonicus, as well as the primitive urodele Hynobius nebulosus, have voltage-dependent fertilization; other urodeles...
the use of vermicompost and fall fertilization in soilless culture on strawberry cv. camarosa quality characteristics was evaluated in a factorial based on completely randomized design pot experiment with 5 replicates. experimental treatments were four chemical fertilization timings (no fertilizer, using fertilizer at fall, spring, fall + spring) and three levels of vermicompost (10, 20 and 40%...
Randomized clinical trials (RCTs) demonstrated the equal efficacy of urinary human chorionic gonadotropin (uhCG) and recombinant hCG (rhCG) products in in vitro fertilisation (IVF). However, limitations inherent with RCTs necessitate the reinforcement of RCT results in real-life. We retrospectively analyzed pregnancies after treatment with rhCG and uhCG products (n = 391, and 96, resp.). We fou...
Assisted reproductive technology (ART) has been recognized for its success in treating infertility, a condition that affects 15 percent of couples in the United States. The most popular option is in vitro fertilization (IVF), which relies on embryo culture, selection, and transfer for implantation, with the ultimate aim of pregnancy. Previous embryo selection methods relied on morphological fac...
Fertilization in Fucus serratus is directly proportional to the number of sperm added, saturating at approximately 250 sperm per egg with an apparent Km of 120 sperm per egg. The effect of a range of lectins on fertilization has been tested. Preincubation of gametes with Con A and fucose-binding protein (FBP) inhibited fertilization. At low concentrations this was by specifically binding to egg...
We present a nulliparous woman with mild to moderate ulcerative colitis (UC) and multiple failed cycles of in vitro fertilization (IVF) in whom we achieved a successful, viable pregnancy following clinical and endoscopic UC remission. Infertile patients with inflammatory bowel disease who have failed multiple cycles of IVF should try to achieve clinical remission and mucosal healing (absence of...
BACKGROUND Aspirin is believed to improve the outcome of IVF, but previous conventional meta-analyses on the subject are conflicting. Therefore, we performed a meta-analysis with individual patient data (IPD MA) of randomized clinical trials (RCTs) on the subject. METHODS A systematic literature search was conducted to identify RCTs assessing the effectiveness of aspirin in IVF. Authors were ...
