Gynecologic Infections and Inflammation
Gynecologic infections and inflammation cover the infectious and inflammatory disorders of the female genital tract, spanning the lower tract (vulva, vagina, and cervix) and the upper tract (uterus, fallopian tubes, ovaries, and adjacent pelvic structures). This area groups conditions in which microbial colonisation, sexually transmitted pathogens, or disturbance of the normal vaginal microbiota produce symptoms, tissue inflammation, and, when the upper tract is involved, risks to future fertility.
Definition
Gynecologic infections and inflammation are infectious and inflammatory conditions of the female genital tract, ranging from disturbances of the vaginal microbiota and lower-tract syndromes to ascending infection of the upper reproductive organs.
Scope
The area orients the reader to the major clinical entities in this group: pelvic inflammatory disease, sexually transmitted infections affecting women, bacterial vaginosis, vulvovaginal candidiasis, and cervicitis and urethritis. It frames how lower-tract syndromes (vaginitis, cervicitis) relate to ascending upper-tract disease, why the vaginal microbiome is central to several of these conditions, and how diagnosis rests on symptoms, clinical examination, and microbiological testing. It is an educational overview, not a clinical management resource.
Sub-topics
Core questions
- How does the normal vaginal microbiota protect against genital infection, and what happens when it is disrupted?
- Which lower-tract infections are sexually transmitted, and which arise from the resident or commensal flora?
- How do lower genital tract infections ascend to cause upper-tract disease and pelvic inflammatory disease?
- What distinguishes the principal causes of vaginitis and cervicitis from one another clinically and microbiologically?
Key concepts
- Lower versus upper genital tract infection
- Vaginal microbiome and Lactobacillus dominance
- Ascending infection
- Sexually transmitted versus endogenous infection
- Vaginitis and vaginosis
- Cervicitis as a marker of cervical infection
- Reproductive sequelae (infertility, ectopic pregnancy, chronic pelvic pain)
Mechanisms
A healthy vagina is typically dominated by lactobacilli that maintain an acidic pH and limit the overgrowth of other organisms; disruption of this community underlies bacterial vaginosis and predisposes to other infections (Onderdonk, 2016). Sexually transmitted pathogens such as Chlamydia trachomatis and Neisseria gonorrhoeae infect the cervix and can ascend through the endometrium to the fallopian tubes, producing the inflammation that defines pelvic inflammatory disease (Brunham, 2015). Other syndromes are caused by overgrowth of commensal organisms, as in vulvovaginal candidiasis. The common thread across the area is that infection or microbial imbalance triggers an inflammatory response whose location determines the clinical syndrome and its potential consequences.
Clinical relevance
These conditions are among the most frequent reasons women seek gynecologic care, and untreated upper-tract infection is an important contributor to tubal-factor infertility, ectopic pregnancy, and chronic pelvic pain (Brunham, 2015; Newman, 2015). The area is presented to explain how these disorders are categorised and understood; it describes the landscape of disease rather than providing diagnostic or treatment instructions for any individual.
Epidemiology
Sexually transmitted infections affecting the female genital tract are a large global burden, with hundreds of millions of incident curable infections estimated each year (Newman, 2015). Bacterial vaginosis and vulvovaginal candidiasis are among the most common causes of vaginal symptoms in reproductive-age women, and pelvic inflammatory disease represents the most consequential upper-tract complication.
Evidence & guidelines
The CDC Sexually Transmitted Infections Treatment Guidelines provide a widely used reference framework for the diagnostic categories and management principles across many conditions in this area (Workowski, 2021). Global burden estimates from systematic review and surveillance contextualise their public-health importance (Newman, 2015). This entry summarises such sources for orientation and does not reproduce their management recommendations.

Frequently asked questions
- What is the difference between a lower and upper genital tract infection?
- Lower-tract infections involve the vulva, vagina, and cervix (for example vaginitis and cervicitis), whereas upper-tract infection involves the uterus, fallopian tubes, and ovaries, as in pelvic inflammatory disease. Lower-tract infections can ascend to cause upper-tract disease.
- Are all gynecologic infections sexually transmitted?
- No. Some, such as chlamydial and gonococcal infection, are sexually transmitted, while others, such as bacterial vaginosis and vulvovaginal candidiasis, arise mainly from disturbance or overgrowth of organisms already present in or around the genital tract.
