Condoms are familiar to everyone, but the liquid condom for women is rarely known. It is not a “condom”, but a colorless and transparent gel-like liquid, also known as the “invisible condom”. It can be placed in the vagina before lovemaking to safely kill sperm, antibacterial and poison, thus playing a certain contraceptive effect. Some people think that liquid condoms for women are simply “perfect” as they are not only condom-free, but also antibacterial and lubricating. So, is the female liquid condom really so good? 1, from the point of view of the contraceptive effect female liquid condoms mainly by reducing or killing the activity of sperm to play the effect of contraception, compared to other forms of contraception, its effect is still not stable. Some studies have concluded that the annual failure rate of liquid condoms is as high as 20%, while condoms are only 2%. In addition, according to the authoritative work “contraceptive technology” shows that the liquid condom in the use of alone, the effectiveness of contraception is only 72%. 2, from the point of view of the use of female liquid condoms, generally to be placed in the vagina about 5 to 10 minutes before love, and to wait for a specific period of time before sex; if the effective time after placement did not occur within the “substantial” sexual life, but also need to be placed again; some before sex with a time, after also need to Some of them are used once before and once after sex to ensure the effectiveness of contraception; usually 1 minute after the end to wash in time. And the use of male condoms is much simpler and more convenient, but also do not have to be a specific time limit, as long as the process does not break the set, the contraceptive effect can be guaranteed. 3, from the point of view of safety In general, the use of liquid condoms is safer, but pay attention to the amount of use and the validity of liquid condoms, so as not to affect the contraceptive effect. Compared to other condoms, liquid condoms not only can contraception, but also can kill viruses, clean and stop itching, help lubricate the vagina, etc., especially for the care of gynecological diseases. However, it has been argued that there is no evidence that liquid condoms for women are as effective as condoms in reducing the risk of STD transmission. Also, it is clinically believed that the liquid is alkaline in nature and that its frequent use may cause changes in the vaginal environment, leading to the growth of pathogenic bacteria due to dysbiosis, which can lead to gynecological inflammatory diseases such as vaginitis. Also, some women may experience allergies in the vulva after using it (if this happens, stop using it). Therefore, the female liquid condom is not as safe and convenient as the (male) condom, both in terms of contraceptive effect and method of use. In particular, long-term use is not recommended to avoid damaging the internal environment of the vagina or causing other discomfort. References: [1] Zhou Xiaobo.” Liquid condom” “Invisible condom”?
