Rats on 22.5-hr light:dark cycles had vaginal opening significantly earlier than rats on 26-hr light:dark cycles. This finding might explain the early menarche in blind girls: Their circadian rhythms, like those of rats on 22.5-hr cycles, might be more rapid than normal. Thus a set number of cycles can occur in a shorter time than usual, allowing puberty to take place early.
处于22.5小时光照：黑暗周期的大鼠阴道开口明显早于处于26小时光照：黑暗周期的大鼠。这一发现可能解释了盲女初潮过早的现象：她们的昼夜节律，就像处于22.5小时周期的大鼠一样，可能比正常情况更快。因此，在比平常更短的时间内就可以出现一定数量的周期，从而使青春期提前到来。
