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
Granulocyte colony-stimulating factor (G-CSF), traditionally utilized in hematopoietic disorders, has garnered attention in reproductive medicine for its potential to enhance endometrial receptivity and improve pregnancy outcomes in assisted reproductive technology (ART). This study aimed to compare the effect of G-CSF administration via intrauterine infusion versus subcutaneous injection on pregnancy outcomes in infertile women undergoing IUI, 75 infertile women aged 18–40 years were enrolled and randomly assigned into three groups (n=25 each): Group 1 received 300 µg G-CSF via intrauterine infusion, Group 2 received 300 µg G-CSF via subcutaneous injection, and Group 3 served as the control with no G-CSF treatment. All participants underwent controlled ovarian stimulation followed by IUI. Endometrial thickness and sub-endometrial blood flow indices (PI, RI, V1/V2) were evaluated using Doppler ultrasound. Serum levels of TNF-α, IL-10, and VEGF were measured before and after G-CSF administration. Clinical pregnancy was confirmed by β-hCG testing two weeks after IUI and confirmation by transvaginal ultrasound. Both G-CSF intervention groups demonstrated significant improvements in sub-endometrial blood flow parameters compared to controls, with intrauterine infusion showing the most favorable Doppler indices (p<0.05). Additionally, intrauterine G-CSF administration resulted in upregulation of VEGF and IL-10 and a reduction in TNF-α levels, though differences did not reach statistical significance. Clinical pregnancy rates were higher in the intrauterine group compared to the subcutaneous and control groups, though differences did not reach statistical significance. Intrauterine infusion of G-CSF appears to offer superior benefits in enhancing endometrial receptivity, modulating inflammatory and angiogenic biomarkers, and improving pregnancy outcomes in IUI cycles compared to subcutaneous injection or no treatment. Further large-scale studies are warranted to validate these findings.
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
Successful implantation needs a receptive endometrium, a functional and normal embryo at the stage of blastocyst developmental and a synchronized dialogue between embryonic tissues and maternal tissues. The current study was planned and conducted to investigate the potential role of vaginal pessary of hyaluronic acid on intracytoplasmic sperm injection (ICSI) outcome. This study included 63 infertile women (32 women as study group receiving hyaluronic acid and 31 control group) who were subjected to ovulation induction programs with gonadotropin releasing hormone (GnRH) antagonist protocols for in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI) procedures. Blood samples were taken by Vacutainer tubes and centrifuged according to the manufacturer’s instructions for the preparation of serum samples. Serum samples for Lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1) were obtained from each patient when the basal hormonal status was determined. The second time point is when the samples were obtained on the day of ova pickup, after that the G1 embryos will be transferred inside the uterine cavity. Then performance of endometrial receptivity parameters or patterns evaluation and patients were followed up to do pregnancy test after14 days after embryo transfer. On the day of human chorionic gonadotropin (hCG), there was no significant difference in mean serum Lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1) between hyaluronic acid group and reference group, respectively (p = 0.824). There was no significant difference in mean follicular fluid Lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1) between the hyaluronic acid group and reference group, 0.92 ±0.36 pg/ml versus 0.82 ±0.22 pg/ml, respectively (p = 0.223). Treatment with the hyaluronic acid resulted in non-significant increase in serum and follicular fluid Lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1), and this increment is not related to Lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1) improvement in local blood endometrial blood flow as reflected by reduction in resistive index and pulsatility index with eventual improvement in pregnancy outcome.
Failure to conceive may be deeply upsetting and stressful, eventually leading to social, physical, and psychological implications. This study aimed to evaluate the impact of dual trigger on endometrial receptivity and the role of uterine biophysical profile in estimating the conception rate in women with primary or secondary infertility. A comparative prospective randomized clinical study was conducted at the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies/ Al-Nahrain University, from October 2019 to April 2020. 90 infertile women who were attending the infertility diagnosis clinic of the institute was included in the study, receiving stimulated intrauterine insemination. Vaginal ultrasound was done for all women at the early and mid-follicular phase. The uterine scoring system for reproduction was assessed and total score of 20 was calculated and subsequently correlated to conception rate. A uterine scoring system for reproduction cut-off of 16 showed a sensitivity of 86.4% and a specificity of 75%. Patients with total score of 18, pulsatility index of lower than 1.79, and three or more endometrial contractions had the highest prevalence of successful pregnancy. Individual variables of endometrium (thickness, pattern, blood flow in zone 3, and myometrium features) had no statistical significance Applebaum's uterine score system for reproduction is a simple and non-invasive ultrasonic assessment. Low pulsatility index, endometrial contraction ≥3, and total score of 18 can point to the appropriate endometrial environment for implantation as well as the rate of conception.
Pregnancy cannot develop without a coordinated stability between an invading trophoblast and a receptive maternal decidua. Both the maternal decidua and the trophoblast, which is embryonic, must incessantly regulate and change one another during the processes of implantation, trophoblast invasion, and placentation. The goal of this study was to determine whether intrauterine infusion of hCG at various doses on the day of ovum pick-up would affect endometrial receptivity markers, biochemical markers, and ICSI outcome. To this end, measurements of serum levels of TNF and IL-10, endometrial thickness using ultrasound, and sub-endometrial blood flow indices using Doppler ultrasound were used.Ninety infertile women were randomly assigned to one of three groups: the research group (n = 60) was given intrauterine administration of either 700 IU or 500 IU of hCG on the day of ova pickup. The control group (n = 30) without hCG. On cycle days 2- 3, a plasma hormone level assessment was performed on each patient.In the 700 hCG group, the pregnancy rate was statistically higher (53.3% and 40%in the 500IU group respectively) as compared with the control group C (26.7%), no significant difference in ICSI outcome between group A &B. The RI and PI were significantly lower in group A (700IU) compared to group B and C. The biochemical marker TNA and ratio of TNF/IL-10 also lower in group A confirming role of Hcg in enhancement of implantation. Intrauterine injection of hCG at day of ova pickup significantly improved the endometrial receptivity marker and this effect occur in dose dependent manner
In human-assisted reproduction both partners need to be evaluated during counseling because causes of infertility are due to male factors and female factors. some body hormones play important role in fertile women and cortisol one of these hormones which is essential for normal ovulation, cortisol usually increases during the follicular phase of the menstrual cycle, play a role in the early stages of follicular development by their interaction with aromatase activity and granulose cell functions. To investigate the correlation of cortisol hormonal level in serum and in follicular fluid that relationship with age in women under Intracytoplasmic sperm injection outcome. Its randomized prospective clinical trial study performance conducting in the Higher Institute for Infertility Diagnosis and Assisted Reproductive Technologies / Al-Nahrain University, Baghdad-Iraq, during the period from November2021to June 2022. a total of Sixty-three Infertile Iraqi women, who planned to inter intrasytoplasmic sperm injection program. The blood sample and follicular fluid sample obtained from all infertile women inter intracytoplasmic sperm injection program to measure cortisol hormonal level at specific days of this study. There was increase in cortisol level in women aged between (30-40) years, So there was significant finding between cortisol level and this age group and there was increase in cortisol level in women aged < 30 years at the same day and no significant difference in cortisol level in women age more than 40. Significant differences in cortisol level appear in group of women age between (30-40) years, also the same result appears in group of women age more than > 40 years and no significant differences in cortisol level in women aged < 30. No significant differences in cortisol level in all age women group (30-40) years, <30 years ,and the women age > 40 years.
