What are the diseases transmitted through sexual intercourse? There are 5 common ones

Sexual intercourse is an important way of spreading many diseases. Diseases that can be transmitted through sex mainly include: trichomoniasis, toxoplasmosis, chlamydia and mycoplasma infection, etc. If you don’t want to be troubled by sexually transmitted diseases, you should keep yourself clean in your daily life.

1. Trichomoniasis

Trichomoniasis is a disease caused by human vaginal Trichomonas. It mainly causes sexual reproductive system lesions and can also be transmitted to men through sexual intercourse.

There are three types of Trichomonas that parasitize the human body, namely vaginal Trichomonas, human Trichomonas and oral Trichomonas, which parasitize the urogenital system, vagina and oral cavity respectively. Once infected, Trichomonas can devour sperm and hinder the production of lactic acid. In addition, there is a large amount of secretions in the vagina, which on the one hand affects the survival and motility of sperm, and on the other hand dilutes the sperm and causes infertility. Among trichomoniasis infections in the male reproductive system, the infection rate of prostate trichomoniasis is 25%-70%, and trichomoniasis inflammation of the vas deferens can lead to obstruction of the vas deferens and cause oligospermia or azoospermia.

2. Toxoplasma gondii infection

Toxoplasma, also known as Toxoplasma gondii, is a parasite that infects a wide range of people throughout the world. Cats are its final hosts, and the parasite reproduces and grows in the bodies of cats. There are several ways of transmission: 1. Eating uncooked meat and Toxoplasma cysts; 2. Drinking contaminated water or inhaling droplets of excrement from sick animals; 3. Touching and petting infected cats; 4. Vegetables or tableware are contaminated by cat feces. Pathogens can be transmitted to the fetus through the placenta, causing embryonic death or malformation, etc.

3. Chlamydia infection

One of the main pathogens of non-gonococcal female genital tract infections is Chlamydia trachomatis. The main mode of infection is through sexual contact, followed by indirect transmission through hands, eyes, or clothing and instruments contaminated by the patient. Chlamydia trachomatis develops and multiplies in infected cells, forming various types of inclusion bodies in the cytoplasm. It only infects mucosal epithelial cells and does not invade subepithelial tissues. Female reproductive tract infections can cause Bartholinitis, cervicitis, salpingitis, endometritis, etc. About three-quarters of patients are asymptomatic and easily ignored. Without early diagnosis and treatment, the infection can persist for a long time, spread, and even lead to sequelae such as ectopic pregnancy and infertility.

4. Mycoplasma infection

Another major pathogen of non-gonococcal infection of the female genital tract is mycoplasma, which is the smallest microorganism that can grow independently, has no cell wall, and is polymorphic in morphology. Ureaplasma urealyticum and Mycoplasma hominis often live in the mucosa of the male and female urogenital tracts. Under certain conditions, they can act as pathogens and cause human diseases. Patients have no subjective symptoms after being infected; some experience urethral itching, frequent urination, urinary pain or difficulty urinating; some have purulent discharge from the vagina, and some may have symptoms similar to salpingitis and cause infertility.

5. Genital herpes

Genital herpes is a sexually transmitted disease caused primarily by the herpes simplex virus (HPV) type B. When women are infected with HSV, they will develop vulvitis and vaginitis, which may hinder normal sexual life, reduce the number of sperm entering the vagina and affect their motility; cervicitis and endometritis are not conducive to sperm penetrating the cervical mucus and ascending; intrauterine viral infection, the virus is transmitted to the fetus through the placenta, which can cause fetal death or miscarriage. When men are infected with HSV, they develop prostatitis, which causes semen liquefaction, and can also affect the physiological function of accessory gland secretions, leading to infertility.
