As a result, mating activity is seasonally restricted in many lemur species including mouse lemurs. Male patterns testicular volume (tv: tv increased and remained ~1200-2500mm3 in september-november but highest in. October: high tv for 6 months, highest volume ~2500m3, tv increased and remained high only in september and october, highest in september 2159 mm3. In oestrus in november, first detected gestating in december.
