One of the parameters potentially affecting in vitro growth preimplantation embryos is oxygen concentration culture environment. An increased causes generation ROS which turn can cause damage to cells and seriously disrupt embryonic development. Previous studies have assessed concentrations fallopian tubes several mammals between 5 8%, while levels uterus were found be even lower; similar measurements been confirmed humans. In addition, mammalian showed that low improve embryo Multiple on...
This study investigated the serum levels of resistin, adiponectin and leptin during physiological menstrual cycle. Sixteen women (age: 19-30 years; body mass index: 19.46-24.9) with regular cycles participated. Fasting blood samples were collected on alternate days throughout a full Mean resistin concentrations slightly higher luteal phase (5.30+/-0.23 ng/ml) compared to follicular (4.68+/-0.07 midcycle (4.86+/-0.09 phases (p=0.032). (18.14+/-0.28 significantly lower (21.79+/-0.29 ng/ml,...
Several studies have demonstrated interesting results considering the implication of three growth factors (GFs), namely nerve factor (NGF), erythropoietin (EPO), and insulin-like factor-I (IGF-1) in physiology male reproductive functions. This review provides insights into effects NGF, EPO, IGF-1 on system, emphasizing mainly their sperm motility vitality. In expression pattern NGF system varies according to species testicular development, playing a crucial role morphogenesis...
Background Reproduction ability requires a certain amount of body fat that is necessary for ovulation, menstruation and pregnancy. Fat tissue represents an endocrine organ with high metabolic activity as it produces adipokines such leptin adiponectin. Our aim to examine potential associations between women reproductive age’s ovarian reserves their levels Method 74 19 40 years age consented take part. Based on the patterns reserves, were divided into three main groups: adequate (AOR - Group...
Due to the limitations of conventional semen analysis in predicting a man's fertility potential, sperm DNA fragmentation was recently introduced as novel marker quality. This prospective study undertaken investigate associations between seminal parameters and Greek men. A total 669 subject data were evaluated two groups, normozoospermic (n = 184) non-normozoospermic 485), according WHO 2010 (WHO Laboratory Manual for Examination Processing Human Semen, 5th edn. World Health Organization),...
Erythropoietin (EPO), a hormone secreted mainly by the kidney, exerts its biological function binding to cell-surface receptor (EpoR). The presence of EPO and EpoR in male female reproductive system has been verified. Therefore, some key properties EPO, such as antioxidant antiapoptotic effects, could improve fertilizing capacity spermatozoa. In present study, effect two different concentrations (10 mIU/μL 100 mIU/μL) on bovine sperm-quality parameters was evaluated during post-thawing 4-h...
Cytokines play a critical and multifarious role in follicular maturation. Consequently, they may influence the pregnancy outcome cycles of assisted reproduction. The aim this study was to measure levels tumor necrosis factor-alpha (TNFalpha), vascular endothelial growth factor (VEGF) leptin serum fluids (FFs) from women undergoing controlled ovarian hyperstimulation (COH) for intracytoplasmic sperm injection (ICSI). We tried investigate their interrelationships evaluate them as predictive...
The aim of this study was to investigate and evaluate the frequency antigens classifying ABO Rh blood groups in Greek population. In 3.5% were first generation immigrants with both their parents from countries USSR, while 1.2% had only one immigrant parent, other Greek. We compared distribution previous studies conducted at a time before Greece became destination for refugees East Northeast countries. Blood samples collected year medical students. slightly differentiated comparison relevant...
Preimplantation genetic testing (PGT) for chromosomal screening, based on embryo biopsy, has significant limitations. Cell-free DNA (cf-DNA) been detected in spent culture medium (SCM), opening new horizons the development of non-invasive PGT (ni-PGT). In this study, we evaluated diagnostic performance ni-PGT aneuploidy (niPGT-A), comparing results trophectoderm biopsies (TE) and respective SCM from individually cultured embryos via Next Generation Sequencing (NGS).Forty fresh were analyzed....
