A liquid condom is a water-soluble, odorless, clear gel-like liquid that is placed in the woman’s vagina or applied to the man’s urethra before lovemaking, mainly to prevent pregnancy by killing or reducing the activity of sperm. So, are liquid condoms harmful to the body? Will it affect future fertility? Generally speaking, liquid condoms are not harmful to the body and are relatively safe, but long-term use may have the following effects on the body: 1, vaginal inflammation in women or urinary tract infections in men Clinically, the long-term use of liquid condoms may cause changes in the vaginal environment, resulting in an imbalance in the female vaginal flora, leading to vaginitis and other gynecological inflammatory diseases. In the case of men, it is likely to lead to an imbalance of acid-base in the urethra, which in turn may induce urinary tract infections, etc. Some researchers also said that the current liquid condoms not only can not block the spread of STDs, but also produce some damage to the epithelial cells, thus increasing the risk of pathogenic infections. 2, prone to allergy symptoms Liquid condoms are a chemical class of agents, some people may be used repeatedly after the irritation of the vagina and allergic symptoms. If there is an allergic reaction, you should stop using it immediately. If there are residues of liquid condoms, will it affect my body? Even if there are residues after using liquid condoms, there is no need to be nervous, most of them will be gradually eliminated from the body, just like the medication inserted in the vagina, it cannot be absorbed 100%, so some of them will be gradually eliminated outside the vagina. Pay attention to keep your vulva clean, just wash it with water every day. Will the use of liquid condoms affect future fertility? The use of liquid condoms does not affect future fertility. However, if long-term use causes gynecological inflammation such as vaginitis, and the infection is not intervened in time, it may affect the normal conception. More attention should be paid to the hygiene and health status of the reproductive tract in general. References: [1] Zhou Xiaobo.” Liquid condom” “Invisible condom”? [J].
