Photoperiod modulates oestrogen status, insulin interposed glucose uptake and connexin-43 in testes of golden hamster, Mesocricetus auratus

The environmental photoperiod plays an important role in regulation of seasonal reproductive events. However, with reference tooestrogen status the exact mechanism involved in testicular seasonality is still unclear in general and especially in long-day breeder golden hamster, Mesocricetus auratus. Therefore, in the present study we explored the effect of day length (long day, LD and short day, SD) in modulation of oestrogen level, metabolic and...
