Abstract:Observation and dissection of the urogenital system of an adult Lacerta vivipara was conducted. The results showed that: the excretory system was composed of kidney, ureter and cloaca, the kidney on the left side of the body was bigger than the one on the right side; the reproductive system of adult male L. vivipara was composed ofthe testis, spermaduct, epididymis, and hemipenis; the left spermary of the male was bigger and slightly closer to the head than the right spermary. The reproductive system of the adult femalewas composed of an ovary and oviduct. The size of the ovary on the left side of thr body was the as same as the one on the right side, whereas the left ovary was higher than the right one. During the reproductive period, the L. vivipara’s sex gland became obviously larger than the same sex gland after the reproductive period. Besides, the reproductive system of L. vivipara was similar to these of other oviparous and ovoviviparous lizards.
