Despite the purported advantages of ultrasound guidance during embryo transfer, and the large number of clinical trials published on this topic, recommendations for the use of this technique in daily clinical practice are still under debate. We designed a meta-analysis based exclusively on evidence from published randomized controlled trials, with the aim of analysing the effect of trans-abdominal ultrasound guidance during embryo transfer versus clinical touch and of transvaginal ultrasound guidance (TV-US) versus the trans-abdominal approach on IVF outcomes...

BACKGROUND: In order to overcome the low effectiveness of assisted reproductive technologies (ART) and the high incidence of multiple births, metabolomics is proposed as a non-invasive method to assess oocyte quality, embryo viability, and endometrial receptivity, and facilitate a targeted subfertility treatment. OBJECTIVES: To evaluate the effectiveness and safety of metabolomic assessment of oocyte quality, embryo viability, and endometrial receptivity for improving live birth or ongoing pregnancy rates in women undergoing ART, compared to conventional methods of assessment...

BACKGROUND: The female genital tract is not exposed to seminal plasma during standard assisted reproductive technology (ART) cycles. However, it is thought that the inflammatory reaction triggered by seminal plasma may be beneficial by inducing maternal tolerance to paternal antigens expressed by the products of conception, and may increase the chance of successful implantation and live birth. OBJECTIVES: To assess the effectiveness and safety of application of seminal plasma to the female genital tract prior to embryo transfer in ART cycles...

OBJECTIVE: To investigate the effect of low and high oxygen concentration on embryo development, pregnancy outcome and birth defects of in vitro fertilization-embryo transfer (IVF-ET). METHODS: According to the oxygen concentration of in vitro culture environment, the IVF-ET performed in the Women's Hospital, Zhejiang University School of Medicine during 2013 and 2015 were divided into low oxygen concentration group (n=2036, 5% O2) and high oxygen concentration group (n=4617, 20% O2)...

This study aimed to evaluate the impact of a short insemination procedure on embryo development, assess the reliability of a fertilization check prior to the appearance of pronuclei and elucidate the role of rescue intracytoplasmic sperm injection (R-ICSI). Patients who had ≥9 eggs, were aged <38 years and had normal semen samples were included. The sibling eggs of each patient were divided into two groups; one half for conventional in vitro fertilization (IVF; insemination time, 20 h) and the other half for short insemination (insemination time, 5 h)...

BACKGROUND: Embryo transfer (ET) was traditionally performed two days after oocyte retrieval; however, developments in culture media have allowed embryos to be maintained in culture for longer periods. Delaying transfer from Day two to Day three would allow for further development of the embryo and might have a positive effect on pregnancy outcomes. OBJECTIVES: To determine if there are any differences in live birth and pregnancy rates when embryo transfer is performed on day three after oocyte retrieval, compared with day two, in infertile couples undergoing treatment with in vitro fertilisation (IVF), including intracytoplasmic sperm injection (ICSI)...

BACKGROUND: Subfertility affects 15% of couples and represents the inability to conceive naturally following 12 months of regular unprotected sexual intercourse. Assisted reproduction refers to procedures involving the in vitro handling of both human gametes and represents a key option for many subfertile couples. Most women undergoing assisted reproduction treatment will reach the stage of embryo transfer (ET) but the proportion of embryos that successfully implant following ET has remained small since the mid-1990s...

REVIEW
Julie Brown, Karen Buckingham, William Buckett, Ahmed M Abou-Setta
BACKGROUND: Many women undergoing an assisted reproductive technology (ART) cycle will not achieve a live birth. Failure at the embryo transfer stage may be due to lack of good-quality embryo/s, lack of uterine receptivity, or the transfer technique itself. Numerous methods, including the use of ultrasound guidance for proper catheter placement in the endometrial cavity, have been suggested as more effective techniques of embryo transfer. This review evaluates the efficacy of ultrasound-guided embryo transfer (UGET) compared with 'clinical touch' (CTET), which is the traditional method of embryo transfer and relies on the clinician's tactile senses to judge when the transfer catheter is in the correct position...

Sub-endometrial junctional zone peristalsis is increased by ovarian stimulation and traumatic embryo transfer, and is linked with decreased implantation and pregnancy rates in assisted reproduction treatments. Various agents have been used to inhibit uterine hyper-peristalsis at the time of embryo transfer with conflicting results. This systematic review aimed to identify if uterine relaxants administered in the peri-implantation period during assisted reproduction treatments could improve pregnancy outcomes through literature search with no language restrictions...

There are currently various protocols for in vitro fertilization (IVF). For patients with polycystic ovarian syndrome (PCOS), an optimized protocol for the downregulation of pituitary follicle stimulating hormone and luteinizing hormone via gonadotropin-releasing hormone agonist (GnRHa) remains a challenge. In the present study, the primary endpoint of an ultra-long and a conventional long GnRHa protocol for intracytoplasmic sperm injection/IVF treatments of patients with PCOS was retrospectively compared. In the modified ultra-long protocol group, endometrial thickness, morphology, and blood flow were significantly improved, as compared with in the conventional long protocol group...

STUDY QUESTION: What type of transferred embryo is associated with a lower rate of ectopic pregnancy? SUMMARY ANSWER: The lowest risk of ectopic pregnancy was associated with the transfer of blastocyst, frozen and single embryo compared with cleavage stage, fresh and multiple embryos. WHAT IS KNOWN ALREADY: Ectopic pregnancy is a recognized complication following assisted reproductive technology (ART) treatment. It has been estimated that the rate of ectopic pregnancy is doubled in pregnancies following ART treatment compared with spontaneous pregnancies...

OBJECTIVE: Components of the insulin-like growth factor (IGF) system enhance in vitro embryo quality and implantation rates in both animal models and human in vitro fertilization (IVF). We evaluated whether differences in serum levels of these components in women prior to initiation of an IVF cycle would be predictive of subsequent outcome. STUDY DESIGN: In this retrospective study sera from women obtained at day 2 of their IVF cycle (at baseline before stimulation) were assayed for IGF-I, IGF-II, and IGF binding protein (BP)-1 by enzyme-linked immunosorbent assay...

PURPOSE: Morphological evaluation is currently considered the single most important predictive measure for assessing embryo quality. The aim of this study was to investigate whether cycles with at least one non-cleaved embryo (i.e., a 1-cell embryo on day 3) have different outcomes compared with cycles in which all embryos had cleaved by day 3. METHODS: All autologous IVF/ICSI cycles with a fresh day 3 transfer and without using a gestational carrier performed at our center between 1/1/2010 and 12/31/2011 were analyzed retrospectively...

Sperm morphology is the best predictor of fertilization potential, and the critical predictive information for supporting assisted reproductive methods selection. Given its important predictive value and the declining reality of semen quality in recent years, the threshold of normal sperm morphology rate (NSMR) is being constantly corrected and controversial, from the 4th edition (14%) to the 5th version (4%). We retrospectively analyzed 4756 cases of infertility patients treated with conventional-IVF(c-IVF) or ICSI, which were divided into three groups according to NSMR: ≥14%, 4%-14% and <4%...

BACKGROUND: Since 1978, when Patrick Steptoe and Robert Edwards achieved the birth of the first test tube baby, assisted reproductive techniques have been refined and improved. However, the rate of successful pregnancies brought to term has barely increased. Therefore closer evaluation of the interventions is needed along with working towards improving uterus receptivity. Vasodilators have been proposed to increase endometrial receptivity, thicken the endometrium and favour uterine relaxation, all of which could improve uterine receptivity and enhance the chances for successful assisted pregnancies...
