To date, a large amount of conclusive evidence has been submitted which demonstrates that adrenalin is antagonistic to spermatogenesis. In general though, very little work has been done concerning the possibilities of recovery of the reproductive system after it has been subjected to adrenalin treatment. More specifically, in the slight amount of work concerned with the possibilities of recovery of the reproductive system of the male frog, adequate conclusions have been hindered by the presence of "residual spermatozoa" i.e., spermatozoa formed during the period preceeding treatment. These sperm are not generally eliminated from the testes, and remain in the tubules. Two important problems arise to which answers are necessary before any conclusive experiments with respect to recovery could be attempted with male frogs. They can be stated as follows: 1) Can the "residual spermatozoa" be moved from the testes of the frog, and 2) If the first question is in the affirmative, what are the conditions under which experiments on the possible recovery of the reproductive system might be successfully carried out after impairment of spermatogenesis? This thesis will be concerned with these two problems.
