Summary

Under the conditions prevailing at the Station de Zoologie expérimentale (University of Geneva), the fertility of males ofXenopus laevis decreases every year in the autumn (Figure). ‘Long-day’ treatment significantly increases the fertility and leads to the conclusion that the decrease is due to photoperiodic influences. Treatment with Antex (Leo) (i.e. a follicle-ripening hormone) for 3 weeks highly activates spermatogenesis at a time when the gonads normally remain inactive.
