Trichomonas vaginitis is a common female reproductive tract infection caused by trichomonas parasites. This disease poses a serious threat to women\’s reproductive health because trichomonas can swallow sperm and reduce sperm motility, thus affecting a woman\’s ability to conceive. In the early stages of pregnancy, if a woman suffers from trichomonas vaginitis, if it is not treated in time, it may lead to serious consequences such as premature delivery and miscarriage.
For most patients, once diagnosed with trichomonas vaginitis, doctors usually prescribe drugs such as metronidazole for treatment. Metronidazole is a highly effective anti-trichomoniasis drug that can effectively kill trichomonas in the vagina. However, because metronidazole is a Category B drug in the FDA pregnancy risk classification, although animal experiments have shown that it is harmless to the fetus, there is a lack of sufficient clinical research data to prove that it is absolutely safe for pregnant women and fetuses. Therefore, for women in early pregnancy, especially in the first three months of pregnancy, doctors usually weigh the pros and cons and carefully consider the necessity of medication. 
In addition to systemic medication, local treatment is also one of the commonly used treatments for trichomonas vaginitis. Topical treatments include medications such as effervescent vaginal tablets, pessaries, or gels containing metronidazole. This treatment method can directly apply the drug to the vaginal mucosa, increase the local drug concentration, and at the same time reduce the systemic side effects of the drug. However, the disadvantage of local treatment is that it may not completely cover all parts of the vaginal wall, especially in those places where trichomonas may hide, such as the cervical canal, around the urethra, etc., and may not achieve the ideal treatment effect.
In addition to drug treatment, improving personal hygiene habits is also an important measure to prevent and control the recurrence of trichomonas vaginitis. Patients should avoid using harsh soaps and lotions to clean the vulva, as this can disrupt the normal balance of vaginal flora and provide favorable conditions for the growth of trichomonas. At the same time, you should wear cotton underwear with good breathability to avoid excessively humid environments, because trichomonas like to survive in warm and humid environments. During treatment, both partners should receive examination and treatment at the same time to prevent cross-infection or mutual reinfection.
Trichomonas can devour sperm. When suffering from trichomonal vaginitis, purulent secretions in the vagina increase in large quantities, and the secretions contain a large number of white blood cells, which will hinder the survival of sperm and reduce the number of sperm. . Low sperm count and poor motility may lead to infertility. For most people, fertility can be restored after treatment of trichomoniasis.
How to treat trichomoniasis in pregnant women
The specific drug for treating trichomoniasis is metronidazole, but pregnant womenEarly use of metronidazole may cause fetal malformations. Metronidazole can also enter the fetus through the placenta, so it is generally recommended not to take it before 20 weeks of pregnancy. Topical treatments may be used during treatment. In addition, oral metronidazole can be excreted in breast milk and should not be used by breastfeeding women.
Why it is important to adhere to treatment when suffering from trichomoniasis vaginal infection
Not only for Trichomonas vaginalis infection, but also when other vaginitis occurs, patients are also required to adhere to treatment and complete the course of treatment . Trichomonas vaginalis is a highly viable single-celled protozoa. When the living environment is not suitable for its growth, the trichomonads will turn into a spherical body, its activity will be significantly weakened, and its sensitivity to the external environment will also be reduced. Nitroimidazole drugs are mainly used to treat trichomoniasis, and there are two treatment methods: oral and topical. Oral medications are used to eliminate hidden trichomonas in the urethra, paraurethral glands, Bartholin glands, and cervical canal. It is difficult to eliminate trichomonas in these areas with topical medications alone. If only local vaginal treatment is used, even if the Trichomonas in the vagina is killed, the Trichomonas that have not been eliminated in the urethra and other places can continue to grow and continue to enter the vagina, making Trichomonas vaginalis untreatable for a long time. Perhaps after the use of topical drugs, under the action of the drugs, Trichomonas vaginalis temporarily changes its way of survival. If the patient does not adhere to treatment, the trichomonas may regain viability and continue to grow after the drug wears off.
