[Establishment of spermatogenesis in guinea-pigs at puberty].
The establishment of spermatogenesis in the guinea-pig was studied by a microscopic method. The spermatogenesis starts before day 16 and the first spermatozoa appear on day 55. Spermatozoa are seen in the tail of the epididymis on day 60 and in the ductus deferens between day 70 and day 80. Relations exist between increase of testicular testosterone and setting of spermatogenesis in the guinea-pig.
