In a questionnaire survey called “How much do you know about STD” conducted by a website for 500 female netizens, more than half of the respondents had little understanding of STD, and some respondents who thought they knew about STD had a fragmented understanding of STD. Due to the lack of basic knowledge about STDs, many women see STDs as a flooding beast, and more often associate it with moral quality. In fact, STD and other infectious diseases, is only a contagious disease, but is only related to sexual activity. We should not take it lightly, paralyzed; nor should we be overly nervous, and we should not think that having an STD means a death sentence. From the medical point of view, STDs and other diseases are not essentially different, as long as there is sexual activity, it is inevitable that pathogens will be infected. The more open the society, the more frequent the human interaction, the greater the chance of suffering from STDs. In recent years, the number of STD patients in China has increased at a rate of about 15% per year. Although STD infections are predominantly male, women are more likely to contract STDs than men in terms of their physiological structure. Foreign research found that healthy women and male STD patients sexual contact, the female contact 1 infection rate of up to 80% to 90%; healthy men and female STD patients sexual contact, male contact 1 infection rate of only 20% to 50%. Researchers believe that this is related to the female reproductive organs are more complex and physiological functions are more special. 1, the female internal and external genitalia have more glands, crypt, folds and a more humid environment, which is conducive to the survival of gonococci and other STD pathogens; 2, estrogen in the female body has the effect of promoting bacterial growth and reproduction; 3, the more widespread use of intrauterine devices in women increases the possibility of gonococcal infection; 4, the contraction of the uterus during female sexual excitement can cause gonococci to travel up to the uterine cavity and fallopian tubes; 5. The breakage of the endometrium during menstruation makes it easier to infect gonococci and other germs during sexual intercourse; 6. Abortion often damages the cervix and endometrium and reduces systemic resistance, thus providing an opportunity for gonococci and other germs to infect. Obviously, the biological structure of the female reproductive organs is much more complex than that of men, and the female reproductive organs have more unique physiological functions than men, before and after sexual intercourse are more difficult to clean than men, so that women are often more susceptible to STDs than men. Therefore, avoiding unclean sexual contact is the most crucial part of STD prevention. Have absolute knowledge of your sexual partner and do not have sex with someone you do not know. If you find any abnormalities in your sexual partner’s reproductive organs before you start having sex, it is best to avoid this sex. The only way to avoid STDs is to ensure that your sexual partner is free of STDs to the greatest extent possible. Take protective measures during sex, such as using male condoms and female condoms. In fact, condoms were originally invented to prevent syphilis. These methods are encouraged whether or not contraception is needed. However, it is important to emphasize that condoms are not 100% safe and have a failure rate of about 10% or more. Pay attention to the hygiene of sexual life to keep the genital organs clean and hygienic. Men should always scrub the penis, penis head and scrotum surface, and women should also bathe often to keep their vulva clean. Pay attention to the hygiene of eating and living, do not share towels, bath towels, intimate clothing, toothbrushes, etc.. You should not share razors, injection needles, etc. The underwear used by STD patients should be strictly disinfected, and when you go out, pay attention to choosing hotels and bathrooms with good hygiene conditions.
