Preparation of fowl testes as recipient organs to germ-line chimeras by means of gamma-radiation
Original language 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 by50 %. 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 th
