“…[17] Ultrasound guidance helps in depositing embryos a-traumatically to the mid-portion of the uterus without touching the fundus. A meta-analysis of 17 Randomized controlled trials (RCT) studies conducted by Cochrane[18] comparing ultrasound vs. clinical touch showed increased pregnancy rate with ultrasound guidance. In the present study, all ETs were done under ultrasound guidance.…”

AIM:To correlate the ease or difficulty of embryo transfer and blood at catheter tip with pregnancy rate when embryo transfer (ET) was performed by the same operator using soft catheter.MATERIALS AND METHODS:A retrospective analysis of 342 patients who underwent in vitro fertilization or ICSI cycle from January 2008 to December 2010 in a single centre was done. The type of transfer was divided into two groups: ‘easy’ or ‘difficult’. Transfer was considered difficult when additional instrumentation was required or firmer catheter was used or required changing of catheter. Patients undergoing cryo-preserved ET were excluded from the study.RESULTS:On the day of transfer in 284 (83%) patients, ET was easy and difficulty was encountered in 58 (17%) patients. Blood at catheter was seen in 101 (29.53%) patients. In the group of 58 difficult transfers, 10 pregnancies resulted with a clinical pregnancy rate of 17.2%, while 67 pregnancies resulted in 284 cycles of easy transfer with clinical pregnancy rate of 23.6% (P value = 0.045). While no significant difference was seen in pregnancies with blood on outer catheter and blood less transfer, there was significant reduction in pregnancy rate when blood was present on catheter tip compared to bloodless transfer (13.3% v/s 24.1; P value = 0.032).CONCLUSION:Reduction in clinical pregnancy rate is seen with difficult ETs, more when blood is present at the catheter tip.

“…Successful embryo transfer (ET) is arguably one of the most crucial steps of an assisted reproductive technology (ART) cycle. Several factors have been reported to affect pregnancy rates, including the ease of ET, use of ultrasound guidance, type of transfer catheters and crucially the position of embryo deposition. The latter has been the focus of several studies that have investigated both the position of the ET catheter tips and the position of the air bubbles deposited along with the embryo following ET.…”

“…Systematic reviews have shown that US guidance improves the clinical pregnancy, ongoing pregnancy, and live-birth rates in women when compared with the standard clinical touch method [1]- [4]. Ultrasound helps in confirming the position of the catheter tip within the uterine cavity, properly determining the site of embryo deposition, and decreasing the frequency of "difficult" ETs [2].…”

Objectives: To facilitate embryo transfer technique in cases with previous failed or difficult transfer using office hysteroscopy. Study Design: Case report of 3 cases of previous difficult embryo transfer (ET). Methods: Hysteroscopic assisted insertion of cervical stent at the end of withdrawal bleeding in the stimulation cycle. This stent was used as a track for embryo transfer catheter. Results: One case cancelled before (embryo transfer) ET and the other 2 cases didn't get pregnant in spite of easy embryo transfer. Conclusion: This hysteroscopic assisted ET technique may facilitate ET technique in cases with difficult embryo transfer due to deformed cervix.
