Compared to the free ring and the self-paid ring, of course the self-paid ring is better. Because our country is in the stage of development, it is not possible for us to provide free services to all women who plan to use contraception, so the free IUD is relatively cheaper and the self-paid IUD is relatively more expensive. Moreover, the contraceptive effect of self-funded ring will be better, like the current clinical self-funded ring, Gongxi ring, Memory ring, Zhimei ring, and Gini ring, are all better birth control rings, especially Gongxi ring, the contraceptive effect can be as high as 99.5% in clinical practice. Therefore, if you have the condition, it is recommended to use the self-funded IUD. In addition, the validity of the self-funded ring can be up to 15 years, it is recommended to go to the hospital within 3-7 days after menstruation.
