The historic taboo associated with the examination of female genitalia has long inhibited the science of gynaecology. This 1822 drawing by Jacques-Pierre Maygnier shows a "compromise" procedure, in which the physician is kneeling before the woman but cannot see her genitalia. Modern gynaecology has shed these inhibitions.

Gynaecology or gynecology from the Greek, gynaika (γυναίκα) meaning woman is the medical practice dealing with the health of the female reproductive system (uterus, vagina, and ovaries). Literally, outside medicine, it means "the science of women". It is the counterpart to andrology, which deals with medical issues specific to the male reproductive system.

Almost all modern gynaecologists are also obstetricians (see obstetrics and gynaecology). In many areas, the specialties of gynaecology and obstetrics overlap. Gynaecology has been considered to end at 28 weeks gestation, but practically there is no clear cut-off. Since 1st October 1992, this cut-off may be considered to occur at 24 weeks gestation in the United States, since the law and definition of abortion changed to bring it closer to the gestation at which a foetus becomes viable.

Etymology

The word "gynecology" comes from the Greek gyno, gynaika meaning woman + logia meaning study, so gynecology literally is the study of women

History

The Kahun Gynaecological Papyrus is the oldest known medical text of any kind. Dated to about 1800 B.C., it deals with women's complaints—gynaecological diseases, fertility, pregnancy, contraception, etc. The text is divided into thirty-four sections, each section dealing with a specific problem and containing diagnosis and treatment, no prognosis is suggested. Treatments are non surgical, comprising applying medicines to the affected body part or swallowing them. The womb is at times seen as the source of complaints manifesting themselves in other body parts.

According to the Suda, the ancient Greek physician Soranus of Ephesus practised in Alexandria and subsequently Rome. He was the chief representative of the school of physicians known as the "Methodists". His treatise Gynaikeia is extant (together with a 6th-century Latin paraphrase by Muscio, a physician of the same school).

In the United States, J. Marion Sims is considered the father of American gynaecology.

Examination

Gynaecology is typically considered a consultant specialty. In some countries, women must first see a general practitioner (GP; also known as a family practitioner (FP)) prior to seeing a gynaecologist. If their condition requires training, knowledge, surgical technique, or equipment unavailable to the GP, the patient is then referred to a gynaecologist. In the United States, however, law and many health insurance plans allow/force gynaecologists to provide primary care in addition to aspects of their own specialty. With this option available, some women opt to see a gynaecological surgeon without another physician's referral.

As in all of medicine, the main tools of diagnosis are clinical history and examination. Gynaecological examination is quite intimate, more so than a routine physical exam. It also requires unique instrumentation such as the speculum. The speculum consists of two hinged blades of concave metal or plastic which are used to retract the tissues of the vagina and permit examination of the cervix, the lower part of the uterus located within the upper portion of the vagina. Gynaecologists typically do a bimanual examination (one hand on the abdomen and one or two fingers in the vagina) to palpate the cervix, uterus, ovaries and bony pelvis. It is not uncommon to do a rectovaginal examination for complete evaluation of the pelvis, particularly if any suspicious masses are appreciated. Male gynaecologists may have a female chaperone for their examination. An abdominal and/or vaginal ultrasound can be used to confirm any abnormalities appreciated with the bimanual examination or when indicated by the patient's history.

Diseases

The main conditions dealt with by a gynaecologist are:

1. Cancer and pre-cancerous diseases of the reproductive organs including ovaries, fallopian tubes, uterus, cervix, vagina, and vulva
2. Incontinence of urine.
3. Amenorrhoea (absent menstrual periods)
4. Dysmenorrhoea (painful menstrual periods)
5. Infertility
6. Menorrhagia (heavy menstrual periods). This is a common indication for hysterectomy.
7. Prolapse of pelvic organs
8. Infections (including fungal, bacterial, viral, and protozoal)

There is some crossover in these areas. For example, a woman with urinary incontinence may be referred to a urologist.

Therapies

As with all surgical specialties, gynaecologists may employ medical or surgical therapies (or many times, both), depending on the exact nature of the problem that they are treating. Pre- and post-operative medical management will often employ many "standard" drug therapies, such as antibiotics, diuretics, antihypertensives, and antiemetics. Additionally, gynaecologists make frequent use of "specialized" hormone-modulating therapies (such as Clomifene citrate and hormonal contraception) to treat disorders of the female genital tract that are responsive to pituitary and/or gonadal signals.

For lists of gynaecological drugs (by the ATC classification system), see ATC code G01 and ATC code G02.

Surgery, however, is the mainstay of gynaecological therapy. For historical and political reasons, gynaecologists were previously not considered "surgeons", although this point has always been the source of some controversy. Modern advancements in both general surgery and gynaecology, however, have blurred many of the once rigid lines of distinction. The rise of sub-specialties within gynaecology which are primarily surgical in nature (for example urogynaecology and gynaecological oncology) have strengthened the reputations of gynaecologists as surgical practitioners, and many surgeons and surgical societies have come to view gynaecologists as comrades of sorts. As proof of this changing attitude, gynaecologists are now eligible for fellowship in both the American College of Surgeons and Royal Colleges of Surgeons, and many newer surgical textbooks include chapters on (at least basic) gynaecological surgery.

Some of the more common operations that gynaecologists perform include:

1. Dilation and curettage (removal of the uterine contents for various reasons, including partial miscarriage and dysfunctional uterine bleeding refractive to medical therapy)
2. Hysterectomy (removal of the uterus)
3. Oophorectomy (removal of the ovaries)
4. Tubal ligation
5. Hysteroscopy
6. Diagnostic laparoscopy – used to diagnose and treat sources of pelvic and abdominal pain; perhaps most famously used to provide definitive diagnosis of endometriosis.
7. Exploratory laparotomy – may be used to investigate the level of progression of benign or malignant disease, or to assess and repair damage to the pelvic organs.
8. Various surgical treatments for urinary incontinence, including cystoscopy and sub-urethral slings.
9. Surgical treatment of pelvic organ prolapse, including correction of cystocele and rectocele.
10. Appendectomy – often performed to remove site of painful endometriosis implantation and/or prophylactically (against future acute appendicitis) at the time of hysterectomy or Caesarean section. May also be performed as part of a staging operation for ovarian cancer.
11. Cervical Excision Procedures (including cryosurgery) – removal of the surface of the cervix containing pre-cancerous cells which have been previously identified on Pap smear.
