In recent years increasing evidence proposed that local immune cells at implantation site have largely contributed to embryo implantation. The intrauterine infusion of activated peripheral blood mononuclear cells culture 2 days before embryo transfer can enhance the implantation. One of the methods used to evaluate the endometrial receptivity is by assessing the sub endometrial blood flow. A total of 67 infertile women (30) women receives intrauterine non-invasive insemination of peripheral blood mononuclear cells (PBMC) culture 2 days before embryo transfer representing the PBMC test group, and (37) women without receiving any cell as Non-PBMC group. The cultured PBMC are administered into the uterine cavity of the patients. 2 days later, embryos are transferred into the uterine cavity. Endometrial thickness and sub-endometrial blood flow measurements are taken for all cases on trigger and embryo transfer days. On embryo transfer day there was no significant difference (p = 0.770) in mean endometrial thickness between the PBMC group and Non-PBMC group. There was a significant difference (p< 0.001) in the mean resistive index; the level being lower in the PBMC group. Moreover, there was a significant difference (p< 0.001) in the mean pulsatility index. Regarding all enrolled women, the pregnancy rate of 25.4 %, the rate was higher in the PBMC group in comparison with the Non-PBMC group, 43.3 % versus 10.8 %, respectively and the difference was significant (p = 0.002). The use of PBMC culture can improve sub-endometrial. Endometrial Receptivity, ICSI, Fresh Embryo Transfer, Peripheral
For successful implantation, a high-quality embryo, receptive endometrium, and tight communication between the two are required. The lack of uterine contractions during embryo transfer is one of the characteristics that greatly affects endometrial receptivity. This is because it has been observed that ET may cause uterine contractions, which may be harmful to embryonic apposition and endometrial blood flow .The aim of this study was to assess how magnesium sulfate administration on the day of embryo transfer improve sub endometrial blood flow, endometrial receptivity, and increase implantation rate and clinical pregnancy rate . Eighty infertile women undergoing ART cycles participated in this prospective. Recombinant FSH (Gonal-F) was used in a controlled ovarian hyperstimulation technique. The first group A (n=40) got a 4gm infusion of magnesium sulfate, while the second placebo control group B (n=40) received 200ml of 5% glucose water as a placebo, respectively. While there were no significant changes in body mass index (BMI), endometrial thickness, number of transferred embryos, or embryo transfer day, significant variations were seen in patient mean age (p<0.001) and mean number of grades I embryo (P=0.003). It was significantly different after magnesium sulfate administration with the lowest value in magnesium sulfate group (P=0.024; P <0.001 and P <0.001 respectively). Implantation rate and clinical pregnancy rate both increased after drugs administration although it was non-significant (P= 0.106 and P= 0.348 respectively). It appears that magnesium sulfate injection before to embryo transfer can significantly increase sub endometrial vascularity and endometrial receptivity and improving implantation rate and clinical pregnancy rate non significantly in ICSI cycles by lowering uterine muscular
