Abstract:
Maintenance of adult male marmosets in continuous light for 60 days had no effect on the circadian rhythmicity of plasma testosterone levels, spermatogenesis or fertility. The results indicate that photoperiodicity is not the environmental determinant that regulates reproduction in male marmosets.
