PURPOSE: To assess the safety of reimplantation of cryopreserved ovarian tissue from advanced-stage breast cancer patients. METHODS: Cryopreserved ovarian cortical fragments were obtained from 13 advanced-stage breast cancer patients aged …

PURPOSE: This study uses linked cycles of assisted reproductive technology (ART) to examine cumulative live birth rates, birthweight, and length of gestation by diagnostic category. METHODS: We studied 145,660 women with 235,985 ART cycles…

PURPOSE: Previous studies reported that patients with endometriosis had excess nitric oxide (NO) in the reproductive tract and poor embryo development in IVF cycles. This study aims to elucidate the effects of NO on early embryo development…

PURPOSE: To determine embryo and cycle-specific parameters associated with twin live birth in day 3 cryopreserved double embryo transfer (DET) cycles, and to propose a new prediction model for external validation. METHODS: All cycles with …

PURPOSE: To examine the relationship between serum total oxidant (TOS) and antioxidant (TAS) levels and clinical pregnancy in assisted reproductive technology (ART) cycles. METHODS: Prior to and after oocyte pick-up (OPU) and embryo transf…

PURPOSE: To evaluate whether psychological stress, as well as changes in hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) at different time points during a first in vitro fertilization (IVF) cycle, correlates w…

PURPOSE: The aim of this study was to analyze the outcomes of IVF/ICSI cycles in women aged 43 and beyond. METHODS: Retrospective analysis of clinical pregnancy and live birth rates in 168 fresh, non donor, ART cycles performed in two Conn…

PURPOSE: In IVF procedures, endometrial function is a limiting factor of the pregnancy rate and the aims of this study is to determine whether seminal plasma insemination at ovum pick-up in IVF has any effect on pregnancy rate. METHODS: We…

PURPOSE: To investigate whether androgen conversion rates after supplementation with dehydroepiandrosterone (DHEA) differ, and whether differences between patients with diminished ovarian reserve (DOR) are predictive of pregnancy chances in…

PURPOSE: To generate novel, objective variables that resemble embryo quality and relate them to ongoing implantation, using multilevel imaging of single-transferred embryos. METHODS: Retrospective analysis of multilevel images of 659 day 3…

PURPOSE: This prospective randomized study used sibling oocytes of 258 women with ≥8 oocytes to compare the effect of 5 % O(2) versus 20 % O(2) concentrations on embryo development and clinical outcome. METHODS: Oocytes of each case were d…

PURPOSE: The objective of this study was to investigate the predictive value of anti-Mullerian hormone (AMH) on fertilization rate (FR), blastocyst development, embryo quality, the outcome of the pregnancy and the live birth rate (LBR) foll…

PURPOSE: Although studies of serum anti-Müllerian hormone (AMH) in predicting ovarian reserve are numerous, many studies utilized patients under age 40. However, the assessment of ovarian reserve is especially critical in older infertile wo…

PURPOSE: Embryo kinetics analysis is an emerging tool for selecting embryo(s) for transfer. The aim of the present study was to determine morphokinetic parameters easily usable in the laboratory and predictive of embryo development and, mos…

PURPOSE: The goal of this study was to determine whether high E2 levels after controlled ovarian hyperstimulation affect TSH. METHODS: Patients completing ART cycles between April-October 2010 were eligible for this cohort study. 180 patie…

BACKGROUND: Tumor Necrosis Factor Alpha (TNF-α), is a proinflammatory cytokine in the pathogenesis of Polycystic Ovary Syndrome (PCOS). In order to investigate the role of rs1800629 and rs1799964 polymorphisms in relation to anthropometric …

PURPOSE: Fibroids are the most common smooth muscle overgrowth in women. This study determined the expression and the effect of hypoxia on two potent antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT) on human fibroid cells.…

PURPOSE: The aim of this study is to determine whether vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) could increase the survival of xenografted human ovarian tissue in an experimental rabbit model. MET…

PURPOSE: To summarise the causes of decreased fecundity with age and review chronological vs biological ovarian ageing. To explore the clinician's means of assessing a woman's ovarian reserve. To review the recent literature on the effectiv…

BACKGROUND: Identification of a non-invasive technique to assess embryo implantation potential in assisted reproduction would greatly increase success rates and lead more efficiently to single embryo transfer. Early studies suggested metabo…

PURPOSE: To evaluate if several genetic loci that are associated with variation in normal menopause age and early menopause can account for a poor response to controlled ovarian stimulation. METHODS: A total of 71 patients age ≤35 years ol…

OBJECTIVE: To determine whether concentrations of oxidative stress markers of follicular fluid and serum are different in GnRH agonist protocol from GnRH antagonist protocol. MATERIAL AND METHOD: This was a cross-sectional study. Eighty-fo…
