Problems solved by technology

[0004] Nonoxynol (NP-9) is the only topical spermicidal contraceptive promoted by the World Health Organization in the world. Although it has a strong spermicidal effect, many studies in recent years have proved that it has hepatic-enteric circulation in the body. , has the ability to accumulate in the body, is toxic to the liver and kidney, and does not have the effect of preventing and treating reproductive tract infections

In 2002, the Cochrane Library published a meta-analysis of all available studies, which concluded that NP-9 may be harmful because it increases the incidence of reproductive tract damage and thus may increase the likelihood of transmission of STDs

[0005] In addition, although there are many other reports on external use of spermicidal contraceptives at home and abroad, such as Chinese herbal medicine pokeweed saponin, achyranthes saponin, pig bile (ZDZ), black plum, cnidium, matrine and western medicine phenylmercuric acetate, chloride Benzethoxyamine, dextropropranolol, sodium morrhuate, phytohemagglutinin, phenolic, phenolic ketones, phenolic acid compounds, benzalkonium chloride (BZN), chlorhexidine (CH), sulfonated polystyrene and miconazole, etc., but they are all in experimental research, and because of their relatively high toxicity and low spermicidal efficacy, they have not been reported to be used in clinical practice.
