As a result of vasectomy, spermatozoa are confined to the epididymis and vas deferens, where they degenerate, releasing antigens that enter the circulation or are engulfed by macrophages. Multiple antigens of the sperm can elicit production of autoantibodies; circulating anti-sperm antibodies are found in a large percentage of vasectomized men, indicating the immunogenicity of the sperm. The increased prevalence of macrophages in the liomen of the rhesus monkey testicular efferent ducts after vasectomy led to further study of this region. Frozen sections were used for evaluation of immunopathological status by fluorescence microscopy with fluorescein-conjugated antibody. Subsequent granular deposits of immune complexes were revealed by positive immunofluorescence staining for complement. The immune complex deposition in the basement membrane surrounding the efferent ducts implies that this region is involved in antigen leakage (Fig. 1).

In seven male monkeys, Macaca mulatta, the infusion of nutrients into the stomach just prior to or 20 h before a 4-h feeding period reduced the feeding by an amount comparable to the calories infused. Pure carbohydrates, fat, protein, and mixtures were employed as infusions and given in a random fashion over a caloric range of 75-300 kcal. In a second series of experiments, monkeys were partially fasted on 1 day and in this way deprived of 75, 150, 300, or 450 kcal. On successive days, they overate to compensate for this deprivation. The smaller deprivations (75 and 150 kcal) were corrected on the first recovery day. The 300-kcal deprivation required 2 days to be corrected while the 450-kcal deficit was only partially restored. These experiments demonstrate the capacities of the monkey to respond with precision to caloric supply and deprivation so as to maintain a constant caloric intake.
