Abstract

BACKGROUND:

The problem of post-cancer infertility is of significant concern. The cryopreservation of ovarian tissue before cancer therapy with retransplantation after convalescence is the key to solving this problem.

METHODS:

Cryopreservation of ovarian tissue was performed in 2005 after surgical operation, post-operative low-temperature 22 hour transportation, and freezing using a special, original design block constructed for the initiation of ice formation (ice-seeding). We present the construction and function of this block.

RESULTS:

In 2011, it was noted that a baby was born after thawing and re-transplantation of ovarian tissue. The technical and biological aspects of initiated crystals formation in the process of cryopreservation are emphasised and discussed.

CONCLUSIONS:

The first live birth in Germany after re-transplantation of cryopreserved ovarian tissue was noted. This cryopreservation was performed using the protocol described here. Block for auto-seeding of principally new construction recommended.
