Description	The aim the study was to investigate the possibility of preparing adult fowl testes for the production of exogenous germ-lines by eradication of recipient spermatogenesis using gammaradiation A comparison between several radiation theraphy treatments (based on Co-60 isotope) of male testes was conducted using gamma-rays of 18, 22 and 26 Gy in a single dose or repeated doses of 5 x 8Gy over a 15-d period. Sperm concetration and motility were determined after each treatment Altered spermatogenesis was observed after a single treatment dose of 18 Gy, while single doses of 26 Gy were followed by reduced sperm numbers (from 22 x 10(9) to 31 x 10(6) sperm/ml) within 60 to 100 d after treatment. After a single treatment of 26 Gy sperm motility was reduced by 50 %. In contrast, a fractionated treatment (5 x 8 Gy) with gamma- razs halted spermatogenesis 39 d after the distribution of the first 8 Gy dose Observations of the seminiferous tubules by electron microscopy performed 12 months after this treatment The aim the study was to investigate the possibility of preparing adult fowl testes for the production of exogenous germ-lines by eradication of recipient spermatogenesis using gammaradiation A comparison between several radiation theraphy treatments (based on Co-60 isotope) of male testes was conducted using gamma-rays of 18, 22 and 26 Gy in a single dose or repeated doses of 5 x 8Gy over a 15-d period.
