One of the most critical steps in the process of in vitro fertilization (IVF) is the embryo transfer. Studies have consistently demonstrated that embryo transfer pregnancy rates differ depending upon the clinician performing the procedure (1–3).

2016年9月5日 · Traditionally, embryo transfer has been performed using tactile senses and judgment to determine when the transfer catheter is in the correct position, this being referred to as ‘clinical touch’. Alternatively, ultrasound imaging can be used to guide placement of the catheter during embryo transfer.

1 天前 · Recurrent implantation failure (RIF) is a common issue in frozen-thawed embryo transfer (FET). Prior to transfer, uterine endometrial receptivity of FET patients can be assessed using multimodal transvaginal ultrasound indicators to predict the success rate of the current FET cycle. Endometrial blood flow is a crucial element in evaluating endometrial receptivity. MV-FLOW™ is an advanced two ...

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.

In this review, we aimed to advise on the best practice for the ultrasound-guided embryo transfer (US-GET) procedure based on the available evidence (both published articles and expert opinion). As the final step in assisted reproduction, expertise and precision in use of this technique is critical for success of the treatment, i.e. achieving a ...

2023年6月7日 · Different types of ultrasound scanning for infertility include: Baseline or screening ultrasound to assess the pelvic anatomy of the uterus, including uterine lining and bilateral ovaries. All abnormal findings are measured and characterized, such as fibroids, uterine malformations, hydrosalpinges, and ovarian cysts.

2018年5月1日 · 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.

2016年10月8日 · Using a cross-sectional ultrasound scan, we can we can identify the position of the cervix in the vagina, facilitating the correct placement of the vaginal speculum (Video 11.1); a longitudinal view is better to assess whether the uterus can be correctly identified (Fig. 11.2 ).

2023年9月8日 · We aimed to determine whether four-dimensional ultrasound guided embryo transfers (4D UGET) could improve pregnancy rates when compared with clinical touch technique (CTT). This was a single...

Traditionally, embryo transfer has been performed using tactile senses and judgment to determine when the transfer catheter is in the correct position, this being referred to as ‘clinical touch’. Alternatively, ultrasound imaging can be used to guide placement of …
