摘　　要：目的:探讨超声动态观测胎儿睾丸下降时间、测量睾丸径线,在及时发现胎儿睾丸发育畸形的意义。方法:对孕龄18～40周的胎儿,采用超声诊断仪(探头频率3～5MHz)动态观测胎儿睾丸下降情况,并测量其大小。结果:正常男性胎儿于孕18周时可见阴茎反射,3%的胎儿于孕18周阴囊内可探及睾丸反射,18%胎儿于孕20周时阴囊内可见睾丸反射,85%胎儿于孕24周时阴囊内可探及双侧睾丸回声及有无鞘膜积液。结论:超声观测有利于了解胎儿睾丸降入阴囊和发育的状况。Objective：To observe the time of male fetus＇s descensus, testiculorum and detect the malformation of fetus＇s testiculus in time by ultrasound. Methods：Study subjectes were the fetuses with gestational age ranging from 18 weeks to 40 weeks. Ultrasonoscope were used , and transducer frequency were 3-5 MHz. Fetus＇s descensus testiculorum were observed periodly, and testiculus＇s diameter line were measured. Results： Penis reflex were observed in the normal male fetuses of gestational 18 weeks. Testiculus reflex were detected in scrotum in 3% fetus after gestational 18 weeks. Testiculus reflex were detected in scrotum in 18% of them after gestational 290 weeks. Both-side testiculus resonance with or without hydrocele were detected in scrotum in 85% after gestational 24 weeks. Conclusions：Observation of ultrasound profits for comprehending state of dropping in scrotum and developing to Fetus＇s testiculuses.
