Abstract

Purpose

Our previous study demonstrated that heterotopic autotransplantation of fresh ovarian tissue followed by transfer of blastocysts supported full-term pregnancy in the mouse. In the present study, to address whether vitrified-warmed ovarian tissue has the potential to support uterine preparation for implantation and subsequent pregnancy to full term, we examined vitrified-warmed ovarian tissue autotransplantation (VOAT) in mice.

Methods

VOAT into kidney capsules was performed for sexual cycle-ceased mice after 7 days of ovariectomy. Uterine potential of decidualization was examined by oil infusion on day 4 of pseudopregnancy. Immunohistochemical analysis was performed to examine the potential in VOAT ovarian tissues. Blastocysts were transferred into uteri on day 4 of pseudopregnancy.

Results

In VOAT mice, uterine decidualization on day 8 of pseudopregnancy was the same as that in intact mice. Blastocyst transfer into the pseudopregnant VOAT mice showed the same rates of pregnancy and live birth pups as intact mice, while less steroidogenesis in the corpus luteum was detected in VOAT mice.

Conclusions

The autotransplantation of vitrified-warmed ovarian tissues after 7 days of ovariectomy restored their sexual cycle and then supported their pregnancy and production of offspring.
