目前,威胁女性生殖健康的2大原因分别是意外妊娠和包括HIV在内的性传播感染(sexually transmitted infections,STIs)。现存的很多避孕方法无法达到预防性传播感染的目的。近年来,研制女性自主使用的、兼具避孕和抗STIs双重功能的外用避孕药具已成为国际发展趋势和热点。处于研究中的双功能避孕药具主要是将杀微生物剂与女用避孕套、SILCS隔膜和阴道环联合使用,前者发挥预防HIV/STIs作用,后者则用于避孕,以此达到双重目的。
At present, the two main causes of female reproductive health are unwanted pregnancies and sexually transmitted infections including sexually transmitted infections (STIs). Many existing contraceptive methods do not achieve the purpose of preventing STIs. In recent years, the development of women’s self-employed, both contraceptive and anti-STIs dual function topical contraceptives has become an international trend and hot spots. The dual-purpose contraceptives under study are mainly used in combination with female condoms, SILCS septum and vaginal ring, the former to prevent HIV / STIs and the latter to contraception, for the dual purpose.
