The Safety of Sino-implant——3-year Clinical Observation
摘要
A total of 315 women who had Sino implant Ⅱ implantation and 302 healthy women were recruited and followed-up for 3 years in order to observe the effect of Sino implant Ⅱ on myoma of uterus and ovarian cysts.The blood pressure,bodyweight,vaginal ultrasonic examination and smear of cervix were measured once a year.The results show that Sino implant Ⅱ does not influence the blood pressure and body weight obviously.There are more ovarian cysts in Sino-implant group than in the control group,but they are all found to disappear when reexamined after menstrua-tion.These ovarian cysts may be follicular cysts.There are fewer myomas of uterus in Sino-implant group than in the control group,and these myomas develop slowly.The results suggest that Sino-implant is a safe contraceptive method.
