title: Effect of testosterone oenanthate on spermatogenesis and serum testosterone concentrations in adult mice.
abstract: Administration of 80 or 160 micrograms testosterone oenanthate s.c. three times per week for 8 or 12 weeks reduced testis weight and increased seminal vesicle weight in mice. Radioimmunoassay indicated that treatment increased serum testosterone concentrations. Treatment with testosterone oenanthate decreased the number of step 16 and step 7 spermatids, pachytene spermatocytes and type A spermatogonia, and particularly reduced the proportion of step 7 spermatids which matured to form step 16 spermatids.
