Lifetime studies were made of the functional state of the sex glands of animals chronically exposed to small doses of radioactive strontium. Spermatogenesis was studied in eight dogs, who were fed Sr/sup 90/, 0.2 or 0.02 mu curie/kg per day for 24 to 40 months. The studies were made by determining the ejaculation volume, total spermatozoa in the ejaculant, percentage of atypical forms, and activity of the spermatozoa. The general systemic condition of the dogs throughout the experiment is discussed, e.g., worsening of dispositions after two or three years, absence of significant weight changes, increased functioning of various organs and systems in the early part of the study. Changes in spermatogenesis were observed in 5 to 1; months and included fluctuations in the functional activity of the glands and increased number of atypical forms of spermatozoa. A persistent depression in spermatogenesis was observed 14 months after the experiment started. The disturbance in spermatogenesis developed earlier than that in the blood-producing system. Two or more years after cessation of administration of Sr/sup 90/, recovery of spermatogenesis was not noted. (TTT)
