The cervix (opening to the womb or uterus) of young women is very susceptible to STDs.
At times, actual penetration is not required to pass disease.
However, it is most often transmitted through sexual intercourse-vaginal, oral and/or anal.
Syphilis can lead to mental illness, blindness, neurological problems, heart disease, and death.
In fact, syphilis causes so many different symptoms that it is commonly called "The Great Imitator" because it mimics so many different diseases.
Gonorrhea of the rectum can also develop through anal intercourse or among women by moving from the vagina to the rectum.
Signs or symptoms may not be obvious for up to several months.
Gonorrhea can lead to infertility and sterility, ability to have or father babies, respectively.
Mothers can also transmit it to babies during birth causing blindness, infection, or death.
Only a doctor or health clinic can diagnose chlamydia.
