使用超声波技术检测了6只雌性四眼斑水龟的卵黄卵泡(包括生长卵泡和排卵前卵泡)、闭锁卵泡和输卵管卵的大小和数量.结果表明:四眼斑水龟卵巢卵黄卵泡数目和大小呈明显的周期性变化,检测到的卵黄卵泡长径范围为4～24 mm(n=186).8月份卵泡数目开始增多,卵泡长径逐渐增大,至12月份排卵前期卵泡数量达最大值,卵巢发育成熟.排卵前期卵泡长径范围为19～24 mm(n=56),最大排卵前期卵泡出现于12月.排卵时间是1月至3月.闭锁卵泡长径范围在10～20 mm(n=14)之间,仅在10月至次年3月能检测到少数的闭锁卵泡.

Ultrasound investigations on vitellogenic follicles and atretic follicles and oviductal eggs were performed on 6 adult female four eye-spotted turtles (Sacalia quadriocellata). The results showed the periodic changes of number and size of ovarian follicles were significant. The diameter of the vitellogenic follicles ranged between 4 mm to 24 mm (n=186). In August, the number of follicles began to increase along with the fall in temperature, and preovulatory follicles reached the maximum number and the ovary was mature in December. Size of preovulatory follicles ranged between 19 mm to 24 mm (n=56) and the largest one was detected in December. Follicles reached ovulatory size from January to March. Atretic follicles, whose diameter ranged between 10 mm to 20 mm (n=14), were only detected from October to the following March.
