INTRODUCTION: Assisted Reproductive Technologies (ART) is increasingly used to help infertile couples to have children around the world. A number of studies have been published reporting an increased risk of major malformations in children born following ART, especially an increased incidence of epigenetic diseases (ED). This study aimed to assess the incidence of epigenetic diseases with affected imprinting genes in infants or children from pregnancies obtained through IVF/ICSI compared to infants or children from pregnancies obtained spontaneously...

STUDY QUESTION: Are the concentrations of five criteria air pollutants associated with probabilities of biochemical pregnancy loss and intrauterine pregnancy in women? SUMMARY ANSWER: Increased concentrations of ambient particulate matter (PM10), nitrogen dioxide (NO2), carbon monoxide (CO) during controlled ovarian stimulation (COS) and after embryo transfer were associated with a decreased probability of intrauterine pregnancy. WHAT IS KNOWN ALREADY: Exposure to high ambient air pollution was suggested to be associated with low fertility and high early pregnancy loss in women...

OBJECTIVE: To compare frozen-thawed embryo transfer (FET) outcomes in natural cycles according to ovulation induction: spontaneous versus recombinant human chorionic gonadotrophin (r-hCG) triggering. METHODS: This retrospective study included all patients monitored for natural cycle FET during one year. When serial monitoring were performed until spontaneous LH rise, patients were included in group A (n=38) whereas those receiving r-hCG for ovulation triggering formed group B (n=43)...

Objective: To compare human chorionic gonadotropin (HCG)-administered natural cycle with spontaneous ovulatory cycle in patients undergoing frozen-thawed embryo transfer (FTET) in natural cycles. Methods: In this retrospective cohort study, we analyzed the clinical outcome of a total of 166 consecutive FTET cycles that were performed in either natural cycle controlled by HCG for ovulation triggering (HCG group, n=110) or natural cycle with spontaneous ovulation (control group, n=56) in 166 infertile patients between January 2009 and November 2013...

BACKGROUND: The initiation of primate embryo invasion into the endometrium and the formation of the placenta from trophoblasts, fetal mesenchyme, and vascular components are essential for the establishment of a successful pregnancy. The mechanisms which direct morphogenesis of the chorionic villi, and the interactions between trophectoderm-derived trophoblasts and the fetal mesenchyme to direct these processes during placentation are not well understood due to a dearth of systems to examine and manipulate real-time primate implantation...

OBJECTIVE: To analyze progesterone and prolactin plasma levels nine days after oocyte retrieval and evaluate their correlation with pregnancy rates in in vitro fertilization cycles. To achieve pregnancy, several factors are analyzed before and during the in vitro fertilization cycle. Progesterone supplementation for adequate luteal phase support is indicated despite the presence of multiple corpus luteum in IVF stimulation cycles because of blockage caused by hypothalamic agonists and antagonists...

Oxidative stress plays a major role in critical biological processes in human reproduction. However, a reliable and biologically accurate indicator of this condition does not yet exist. On these bases, the aim of this study was to assess and compare the blood and follicular fluid (FF) redox status of 45 infertile subjects (and 45 age-matched controls) undergoing in vitro fertilization (IVF), and explore possible relationships between the assessed redox parameters and IVF outcomes. Reactive Oxygen Species (ROS) production, assessed by flow cytometry analysis in blood leukocytes and granulosa cells, significantly increased (p < 0...

Infertility affects ~7% of couples of reproductive age with little change in incidence in the last two decades. ART, as well as other interventions, have made major strides in correcting this condition. However, and in spite of advancements in the field, the age of the female partner remains a main factor for a successful outcome. A better understanding of the final stages of gamete maturation yielding an egg that can sustain embryo development and a pregnancy to term remains a major area for improvement in the field...

PURPOSE: In human oocytes, sERCs are one of the dysmorphic phenotypes that have been reported. Significantly reduced pregnancy rates and a comparatively higher number of abnormities in live births appear to be associated with the presence of sERCs in oocytes. However, some reports have shown that healthy babies can be born, without any reduced pregnancy rates, from oocytes observed to contain sERCs. Thus, the clinical and scientific significance of oocytes that harbor sERCs remains controversial...

Advances in reproductive medicine have significantly increased the success of fertility treatments. Nevertheless, some women experience recurrent implantation failure (RIF) after in-vitro fertilization (IVF) or recurrent pregnancy loss (RPL). Imbalances in the immune system and failure to achieve immune tolerance to the foetus have been implicated as potentially modifiable causes of idiopathic RIF and RPL. As such, women are increasingly being treated with immunomodulatory agents in an attempt to achieve a successful pregnancy...

STUDY QUESTION: Are there any changes in the treatments involving ART and IUI initiated in Europe during 2013 compared with previous years? SUMMARY ANSWER: An increase in the overall number of ART cycles resulting from a higher number of countries reporting data was evident, the pregnancy rates (PRs) in 2013 remained stable compared with those reported in 2012, the number of transfers with multiple embryos (3+) was lower than ever before yet the multiple delivery rates (DRs) remained unchanged, and IUI activity and success rates were similar to those of last years...

Sperm DNA fragmentation (SDF) testing has been emerging as a valuable tool for male fertility evaluation. While the essential role of sperm DNA integrity in human reproduction was extensively studied, the clinical indication of SDF testing is less clear. This clinical practice guideline provides recommendations of clinical utility of the test supported by evidence. It is intended to serve as a reference for fertility specialists in identifying the circumstances in which SDF testing should be of greatest clinical value...

OBJECTIVES: The use of sonography-based Automated Volume Count (SonoAVC; GE Healthcare, Kretz, Zipf, Austria) leads to substantially lower intraobserver and interobserver variability with a considerable advantage in time gain for both the physician and patient. It offers the possibility of continuous training and standardization of follicular monitoring. Manual and automated follicular measurements during in vitro fertilization (IVF) are reported to be comparable during gonadotropin-releasing hormone (GnRH) agonist treatment...

OBJECTIVE: To assess early embryo development via time-lapse in smokers and non-smokers. METHODS: The retrospective study was conducted at Novafertil IVF centers in Konya, Turkey and comprised oocytes of both smoker and non-smoker couples subjected to in vitro fertilisation / introcytoplasmic sperm injection from 2012 to 2015. Age, basal follicle-stimulating hormone, number of stimulation days, amount of gonadotropin used, number of metaphase II oocytes, number of embryos transferred and pregnancy, abortus and clinical pregnancy rates were noted...

BACKGROUND: Pregnancies achieved through in-vitro fertilisation (IVF) are associated with adverse first trimester outcomes in comparison to spontaneously achieved pregnancies. In view of this, it is imperative to predict the success as well as prognosticate the pregnancy outcome of an IVF cycle not only for the clinicians but also the couples undergoing IVF. Serum beta-human chorionic gonadotropin (β-hCG) value has, thus, been used as a biomarker for pregnancy outcome after IVF and also an aid in counselling and management of the patient...
