1. The aim of this study was to evaluate the ability of frozen-thawed testicular cells transplanted into infertile cocks to restore spermatogenesis and to compare two cryoprotectants (CPA) (dimethylsulfoxide (DMSO) and Biofreeze). 2. A total of 24 infertile White Leghorn (WL) cocks were transplanted with cryopreserved testicular cells from fertile adult donor cocks. Both genetically close and phylogenetically distant chicken breeds were used as donor cocks. 3. Twelve out of 24 WL recipient cocks with cryopreserved testicular cells restored spermatogenesis within 2 months after the transplantation. Six out of 12 recipient cocks with restored spermatogenesis successfully produced progeny expressing the donor phenotype. 4. There was no difference between the CPA in cell viability after thawing or in the number of offspring produced from cryopreserved testicular tissue. 5. The present work represents the first report of production of a donor-derived healthy progeny following frozen-thawed testicular cell transplantation in adult birds. The described results may contribute to preservation of endangered avian species and to maintaining their genetic variability.
