This study has analysed the relationship between ovarian response and the number of euploid embryos. This is a post hoc analysis of a subset of data generated during a prospective cohort study previously published. Forty-six oocyte donors were subjected to ovarian stimulation with 150 IU of rFSH and 75 IU of hp-hMG in a GnRH agonist long protocol. Preimplantation genetic screening was performed in all viable embryos. We observed a positive relationship between ovarian response and the number of euploid embryos...

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is the most serious complication of controlled ovarian stimulation (COH) during assisted reproductive technology (ART) protocols. This syndrome is a result of ovarian expression of vascular endothelial growth factor (VEGF), which increases vascular permeability. OBJECTIVES: To evaluate the efficiency of prophylactic and therapeutic use of cabergoline in women with higher risk of developing OHSS. MATERIALS AND METHODS: In this prospective randomized study, 146 women undergoing in vitro fertilization (IVF) cycles with GnRH agonist protocols with a higher risk of OHSS diagnosed during the HCG day administration (more than 18 follicles observed larger than 12mm in diameter during COH and/or estradiol levels of 3000-3500pg/ml, previous episodes of OHSS)...

This study investigated the effects of early induction of autophagy on embryonic development in pigs. For this, oocytes or embryos were treated with an autophagy inducer, rapamycin (RP), during post-activation (Pa), in vitro fertilization (IVF) and/or in vitro culture (IVC). When parthenogenesis (PA) embryos were untreated (control) or treated with various concentrations of RP for 4 hr during Pa, 100 nm RP showed a higher blastocyst formation (48.8 ± 2.7%) than the control (34.6 ± 3.0%). When PA embryos were treated during the first 24 hr of IVC, blastocyst formation was increased (p < ...

Soluble receptor for advanced glycation end products (sRAGE) can decoy the toxic AGEs and is considered to be a protective factor. This study aimed to evaluate the correlation between intrafollicular sRAGE levels and clinical outcomes in infertile women of young or advanced maternal age (AMA) undergoing in vitro fertilization (IVF). A total of 62 young women and 62 AMA women who would undergo IVF were included in this prospective study. The intrafollicular sRAGE concentration was measured to determine its association with the number of retrieved oocytes, fertilized oocytes, high-quality embryos or achievement of clinical pregnancy in young and AMA women, respectively...

The aim of this review is to analyse the effectiveness of exogenous kisspeptin administration as a novel alternative of triggering oocyte maturation, instead of currently used triggers such as human chorionic gonadotropin (hCG) or gonadotropin releasing hormone (GnRH) agonist, in women undergoing in vitro fertilisation (IVF) treatment. Kisspeptin has been considered a master regulator of two modes of GnRH and hence gonadotropin secretion, pulses and surges. Administration of kisspeptin-10 and kisspeptin-54 induces the luteinising hormone (LH) surge required for egg maturation and ovulation in animal investigations and LH release during the preovulatory phase of the menstrual cycle and hypothalamic amenorrhoea in humans...

INTRODUCTION: Oocyte Culture of Germinal Vesicle (GV) and its growth improves Assisted Reproductive Technology (ART) invitro and infertility. Inappropriate culture medium environment, low quality of oocytes, increase in Oxidative Stress (OS) events, Reactive Oxygen Species (ROS) and free radicals production are the main factors that result in unsuccessful Invitro Maturation (IVM) and decrease in reproduction. AIM: The present study was conducted with the aim to evaluate the effect of β-mercaptoethanol (BME) and Cysteamine (CYS) on IVM improvement, embryo fertilization and development of blastocyst of mouse immature oocyte...

BACKGROUND: Research supports that in vitro fertilization causes anxiety and that anxiety can continue into the resulting pregnancy. Most women who have IVF will have a less invasive treatment for infertility prior to IVF; however, it is unclear if specific less invasive treatment cycles impact anxiety that is experienced in the pregnancy resulting from IVF. METHODS: A prospective study was conducted for women who became pregnant via IVF, and data was collected about reported previous non-IVF treatment cycles as well as Pregnancy Related Anxiety Measure...

BACKGROUND: The variability of published acupuncture protocols for patients undergoing In-Vitro Fertilization (IVF) complicates the interpretation of data and hinders our understanding of acupuncture's impact. In 2012, an acupuncture treatment protocol developed by a Delphi consensus process was published to describe the parameters of best practice acupuncture for Assisted Reproductive Technology and future research. However, there has been no clinical trial utilizing this protocol to assess the effects of acupuncture...

The recent discovery of ovarian stem cells in postnatal mammalian ovaries, also referred to as putative stem cells (PSCs), and their roles in mammalian fertility has challenged the long-existing theory that women are endowed with a certain number of germ cells. The rare amount of PSCs is the major limitation for utilizing them through different applications. Therefore, this study was conducted in six phases to find a way to increase the number of Fragilis- and mouse vasa homolog (MVH)-positive sorted cells from 14-day-old NMRI strain mice...

After the introduction of IVF, dietary advice receded into the small print of fertility care. However in recent years, the role of diet as a remediable determinant of reproductive outcomes has garnered increasing interest. Why this resurgence? The acceptance into scientific orthodoxy of the Development origins of Health and Disease (DoHAD) concept has led to the establishment of many large prospective cohort studies designed to discern the impact of various early life exposures on health later in life. The rise in interest on the effects of diet on infertility in part reflects this, but it also derives from another stark reality...

PROBLEM: Implantation failure (IF) even after the good-quality embryo transfer (ET) is main obstacle in in vitro fertilization (IVF). We aim to study the genomics of endometrial receptivity in IF patients under controlled ovarian stimulation (COS) during which ET is generally practised in IVF. METHOD OF STUDY: Endometrial gene expression profiling in IF patients (n=10) and oocyte donors (n=8) were compared during window of implantation under COS by microarray. Enrichment analysis of microarray data was performed to determine dysregulated pathways...

Recent advances in embryo freezing technology together with growing concerns over multiple births have shifted the paradigm of appropriate IVF. This has led to the adoption of new performance indicators for ART clinics by national reporting schemes, such as those curated by the Society for Assisted Reproductive Technology (SART) and the Human Fertilization and Embryology Authority (HFEA). Using these organizations as case studies, we review several outcome measures from a statistical perspective. We describe several denominators that are used to calculate live birth rates...
