Gynecology is the branch of medicine focused on the health of the female reproductive system, including the uterus, ovaries, fallopian tubes, cervix, and vagina. It covers everything from routine screenings and birth control to diagnosing conditions like endometriosis, ovarian cysts, and reproductive cancers. While closely related to obstetrics (which handles pregnancy and childbirth), gynecology specifically addresses health concerns outside of pregnancy.
Gynecology vs. Obstetrics
Most people encounter the combined title “OB/GYN,” which blends two distinct fields into one specialty. The “OB” side covers pre-conception care, pregnancy, labor and delivery, and postpartum recovery. The “GYN” side covers everything else related to reproductive and broader women’s health. A physician who focuses purely on gynecology does not deliver babies or manage pregnancies. An obstetrician, conversely, does not treat health issues unrelated to pregnancy.
In practice, most physicians train in both and handle the full range. Some OB/GYNs even serve as primary care doctors, replacing the need for a separate internist or family practitioner. Whether your provider leans more toward one side depends on their practice and your needs.
What a Gynecologist Treats
Gynecologists manage a wide range of conditions. Some of the most common include:
- Endometriosis: tissue similar to the uterine lining growing outside the uterus, causing pain and sometimes fertility problems
- Uterine fibroids: noncancerous growths in or on the uterus that can cause heavy bleeding and pelvic pressure
- Polycystic ovary syndrome (PCOS): a hormonal condition that can disrupt periods, cause acne or excess hair growth, and affect fertility
- Sexually transmitted infections: including chlamydia, gonorrhea, HPV, and others
- Gynecologic cancers: cancers of the cervix, uterus, ovaries, and other reproductive organs
- Interstitial cystitis: chronic bladder pain sometimes confused with recurrent urinary tract infections
Beyond these conditions, gynecologists also help with contraception, menopause management, hormone-related issues, and infertility evaluation.
Routine Screenings and Preventive Care
A large part of gynecology is preventive. Regular visits include screenings designed to catch problems early, often before symptoms appear.
Cervical cancer screening is the cornerstone of preventive gynecologic care. In the United States, current guidelines from the U.S. Preventive Services Task Force recommend starting Pap smears at age 21, repeated every three years through age 29. From age 30 to 65, you have options: a Pap smear every three years, an HPV test every five years, or both tests together every five years. The American Cancer Society takes a slightly different approach, recommending HPV testing alone every five years starting at age 25. After age 65, most people can stop screening if their previous results have been consistently normal.
HPV testing has become increasingly central to cervical cancer prevention because it is more sensitive than a Pap smear alone at detecting precancerous changes and allows for longer intervals between screenings.
Gynecologists also screen for sexually transmitted infections. Women 25 and older with risk factors should be screened for chlamydia and gonorrhea. A one-time HIV test is recommended for everyone between ages 15 and 65, with annual testing for those at higher risk. Hepatitis C screening is recommended once for all adults ages 18 to 79.
What Happens During a Pelvic Exam
The pelvic exam is the primary diagnostic tool in gynecology. It typically has three parts. First, the provider visually inspects the external genitalia. Next comes a speculum exam, where a small instrument is inserted to allow a view of the vagina and cervix. This is when a Pap smear or STI samples are collected. Finally, a bimanual exam involves the provider pressing on the lower abdomen while inserting one or two gloved fingers to feel the size, shape, and position of the uterus and ovaries.
The entire process usually takes just a few minutes. If the provider finds anything unusual, like a mass or an abnormal area on the cervix, further evaluation with a colposcopy (a magnified view of the cervix) or a tissue biopsy may follow.
When to Start Going
The American College of Obstetricians and Gynecologists recommends a first visit between ages 13 and 15. This initial appointment is mostly a conversation. It typically does not include a pelvic exam. The purpose is to establish a relationship with a provider, discuss menstrual health, and address topics like puberty, hygiene, and eventually contraception. Cervical cancer screening doesn’t begin until age 21 at the earliest, so those early visits are about education and building comfort.
Symptoms Worth Bringing Up
Some symptoms specifically warrant a gynecological evaluation. Johns Hopkins Medicine highlights a few key ones: bleeding between periods, unusually heavy or irregular menstrual bleeding, any vaginal bleeding after menopause, and pelvic pain or pressure that feels different from typical menstrual cramps. These don’t necessarily signal something serious, but they do need a proper workup to rule out conditions like fibroids, polyps, hormonal imbalances, or less commonly, cancer.
Gynecology Subspecialties
After completing their general training, some gynecologists pursue additional specialization. The American Board of Obstetrics and Gynecology recognizes five subspecialties:
- Gynecologic oncology: surgical and medical treatment of reproductive cancers
- Reproductive endocrinology and infertility: hormonal disorders and fertility treatments, including IVF
- Urogynecology: pelvic floor disorders like incontinence and organ prolapse
- Maternal-fetal medicine: high-risk pregnancies (this falls on the obstetrics side)
- Complex family planning: advanced contraception and management of complicated pregnancy loss
Your general gynecologist will refer you to one of these specialists if your condition requires more targeted expertise.
How Gynecologists Are Trained
Becoming a gynecologist requires four years of college, four years of medical school, and then a four-year residency in obstetrics and gynecology (48 months of accredited graduate training). Board certification follows after at least one year of independent practice beyond residency. Subspecialists complete additional fellowship training on top of that. From start to finish, the path takes a minimum of 12 to 13 years after high school.
