Objective: The aim of our study was to measure and compare the serum hormone level of transplant group with blank control and castrated control groups after heterotopic autotransplantation of cryopreserved-thawed ovarian tissues into back muscles. Methods: A total of 40 SPF-SD female rats(5–6 week-old) were randomly divided into three groups: blank control group(group A), castration control group(group B) and transplant group(group C). Ovaries were removed by surgical procedure, then after cryopreservation and thawing procedures the ovarian tissues were implanted into the back muscles of mice in group C. After 4 weeks of ovarian tissues transplantation, all rats blood sampling were measured for E2, LH and FSH hormone levels by ELISA. Results: E2 level was significantly higher in group C and group A than group B [(38.98 ± 5.66) pg/mL,(8.14 ± 3.24) pg/mL; P < 0.05) and [(36.30 ± 6.90) pg/mL,(8.14 ± 3.24) pg/mL; P < 0.05)]. However, E2 level in group C and group A had no significant difference. FSH level in group B, group A and group C was(18.87 ± 2.54) nmol/L,(7.77 ± 0.87) nmol/L and(9.39 ± 2.12) nmol/L respectively. FSH level increased significantly in group B compared with group A, and the difference had statistical significance(P < 0.05). FSH level was slightly increased in group C compared with group A, and the difference was not statistically significant(P > 0.05), but compared with group B, FSH level was significantly reduced and being statistically significant(P < 0.05). Conclusion: Autotransplantation of cryopreserved-thawed ovarian tissue into back muscles can sustain follicular development and re-establish endogenous hormone production by restoring the factors such as angiogenesis and innervations at the graft site.
