Improvement of endometrial thickness and in vitro fertilization outcomes in patients with Asherman's refractory endometrium using autologous mesenchymal stem cells from the stromal vascular fraction.
Objective: Patients with Asherman's Syndrome (AS) and an endometrial thickness (EMT) less than 7 mm are infertile women with suboptimal endometrium due to uterine scarring or endometrial atrophy. This study aimed to examine the effect of intrauterine injections of adipose-derived mesenchymal stem cells (ADMSC) from the Stromal Vascular Fraction (SVF) of adipose tissue on EMT and in vitro fertilization (IVF) outcomes: which are improvements in EMT and pregnancy rates.
Methods: This double-arm retrospective study included 41 AS patients with hysteroscopic adhesiolysis. Twenty-one patients with AS refractory endometrium (Group 2) were given ADMSC to improve EMT, and 20 non-treated, age-matched patients served as controls (Group 1). For Group 2, SVF was isolated from 15 ml of adipose tissue and transmyometrial injected into the patient's uterine cavity. For all patients, EMT was examined using ultrasound before embryo transfer.
Results: In Group 2, after ADMSC treatment, EMT significantly improved (3.2 ± 1.8 mm, P<0.001). Afterward, three patients spontaneously became pregnant, and eighteen underwent frozen embryo transfer. A significant increase in implantation (66.7% vs. 4.8%, P = 0.002) and live birth rates (0.0% vs. 47.6%, P = 0.001) were recorded. No significant difference was observed in EMT, cycle implantation, or clinical pregnancy between the two groups, but the live birth rate in Group 2 after ADMSC treatment was higher than in Group 1.
Conclusion: The results demonstrate that autologous intrauterine ADMSC injection can improve EMT, implantation, and pregnancy rates in AS patients with refractory endometrium. This research underscores the life-changing potential of autologous ADMSC treatment for patients with refractory endometrium, providing a promising avenue for future treatments.
