gonorrhea

10

cervical ectropion

immature cervix that has red bumps out of the cervical os (columnar cells).

11

Why young girls are at higher risk of STDs

their cervix hasn't matured yet; columnar cells are easier to infect than squamous (mature cells)

not needed

30

education about trx for gonorrhea/chlamydia

trx partners within 60 days, avoid sex until therapy completed.

31
