Sinopsis
Excerpt from The Spermatogenesis of Amphiuma: Submitted in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy, in the Faculty of Pure Science, Columbia University
Along the line of attachment of the testis to the mesorchium is a deep groove or hilum. The surface of the entire organ is finely lobulated, the minute lobules being the outer ends of the seminal tubules, which have the form of long cones radially arranged around the linear center of the testis. The blood ves sels pass out, between the tubules, to the surface, which is netted with rosettes of very fine vessels, which are much more conspicuous during the period of actual spermatogenesis. In testes shortly after the breeding season and in those of imma ture animals the blood supply is much less, as is also the case in those portions of adult testes which are distended with ripe spermatozoa.
