One of the problems of in vitro fertilization (IVF) cycles is recurrent failure of implantation. The present study aimed to investigate the effect of intrauterine saline infusion in luteal phase of previous menstrual cycle on occurrence of pregnancy in infertile patients undergoing frozen-thawed embryo transfer.

This clinical trial was conducted in 70 infertile women attending the infertility center in Sari Imam Khomeini Hospital who were undergoing frozen-thawed embryo transfer in 2020. The participants were randomly divided into an intervention group and a control group (n= 35 per group) using random number table. In intervention group, intrauterine injection of saline with ultrasound guidance was performed on day 21 of previous menstrual cycle, while the control group received no intervention. Pregnancy outcomes were compared between the two groups. Data analysis was performed using Chi-square and t-test.

The intervention group and control group were found to be significantly different in rate of clinical pregnancy (6.5%, 28.1%) (P=0.003) and live birth (6.5%, 28.1%), respectively (P=0.02).

In this study, saline infusion sonohysterography did not have positive effect on clinical pregnancy and live birth, which could be due to small sample size, performing the procedure on day 21 of cycle, or ineffectiveness of this method in causing inflammation following scratches compared to conventional methods. Further molecular and cellular studies are needed to compare the effect of these methods on increasing the level of inflammatory factors.

Tamoxifen may have secondary adverse effects on the endometrium. The aim of this study was to investigate the endometrial evaluation in women with breast cancer under tamoxifen therapy with Saline infusion Sonohysterography (SIS).

This cross-sectional study was performed on 40 breast cancer patients under adjutant tamoxifen (20 mg/day for at least 6 months) therapy referred to Amir-al-Momenin hospital in Semnan, Iran, gynecological clinic, by oncologist during 2018 to 2019. Requested data including individual characteristics and results of vaginal sonography, Sonohysterography, Pathology and   hysteroscopy were recorded in checklist.

The mean±SD age of patients was 46.0 ± 6.4 years.  39 patients (97.5%) had amenorrhea. The mean±SD duration of breast cancer was 3.1±1.3 years and the duration of tamoxifen use was 26.3 ± 13.7 months. Sonohysterography was performed without any complication in all patients.  The most important findings in the Sonohysterography were endometrial thickness ≥ 5 mm in 6(15%), echogenic lesion in uterine cavity in 4(10%) and subendometrial cysts in 13 (32.5%) patients. Notably, vaginal sonography found endometrial thickness ≥5 in 16 cases, while Sonohysterography had abnormal findings just in 8 (50%) patients. Overall agreement of Sonohysterography with pathology, hysteroscopy and vaginal sonography was 80%, 80% and 75% respectively.

The findings showed that patients under adjutant tamoxifen therapy are at risk for endometrial pathologies such as polyps and hyperplasia. Sonohysterography is well tolerated and has a good overall agreement with pathologic findings and in comparison with vaginal sonography reduces unnecessary invasive interventions.
