Regular testing for sexually transmitted infections is encouraged for prevention. The risk of contracting pelvic inflammatory disease can be reduced by the following:

- Using barrier methods such as condoms; see human sexual behavior for other listings.

- Seeking medical attention if you are experiencing symptoms of PID.

- Using hormonal combined contraceptive pills also helps in reducing the chances of PID by thickening the cervical mucosal plug & hence preventing the ascent of causative organisms from the lower genital tract.

- Seeking medical attention after learning that a current or former sex partner has, or might have had a sexually transmitted infection.

- Getting a STI history from your current partner and strongly encouraging they be tested and treated before intercourse.

- Diligence in avoiding vaginal activity, particularly intercourse, after the end of a pregnancy (delivery, miscarriage, or abortion) or certain gynecological procedures, to ensure that the cervix closes.

- Reducing the number of sexual partners.

- Sexual monogamy.

- Abstinence

Treatment is often started without confirmation of infection because of the serious complications that may result from delayed treatment. Treatment depends on the infectious agent and generally involves the use of antibiotic therapy. If there is no improvement within two to three days, the patient is typically advised to seek further medical attention. Hospitalization sometimes becomes necessary if there are other complications. Treating sexual partners for possible STIs can help in treatment and prevention.

For women with PID of mild to moderate severity, parenteral and oral therapies appear to be effective. It does not matter to their short- or long-term outcome whether antibiotics are administered to them as inpatients or outpatients. Typical regimens include cefoxitin or cefotetan plus doxycycline, and clindamycin plus gentamicin. An alternative parenteral regimen is ampicillin/sulbactam plus doxycycline. Erythromycin-based medications can also be used. Another alternative is to use a parenteral regimen with ceftriaxone or cefoxitin plus doxycycline. Clinical experience guides decisions regarding transition from parenteral to oral therapy, which usually can be initiated within 24–48 hours of clinical improvement.

Ovarian pregnancies are dangerous and prone to internal bleeding. Thus, when suspected, intervention is called for.

Traditionally, an explorative laparotomy was performed, and once the ovarian pregnancy was identified, an oophorectomy or salpingo-oophorectomy was performed, including the removal of the pregnancy. Today, the surgery can often be performed via laparoscopy. The extent of surgery varies according to the amount of tissue destruction that has

occurred. Patients with an ovarian pregnancy have a good prognosis for future fertility and therefore conservative surgical management is advocated. Further, in attempts to preserve ovarian tissue, surgery may involve just the removal of the pregnancy with only a part of the ovary. This can be accomplished by an ovarian wedge resection.

Ovarian pregnancies have been successfully treated with methotrexate since it was introduced in the management of ectopic pregnancy in 1988.

An ovarian pregnancy can develop together with a normal intrauterine pregnancy; such a heterotopic pregnancy will call for expert management as not to endanger the intrauterine pregnancy.

If tubal factor infertility is suspected to be the cause of the infertility treatment begins with or without confirmation of infection because of complications that may result from delayed treatment. Appropriate treatment depends on the infectious agent and utilizes antibiotic therapy. Treating the sexual partner for possible STIs helps in treatment and prevents reinfection.

Antibiotic administration affects the short or long-term major outcome of women with mild or moderate disease.

For women with infections of mild to moderate severity, parenteral and oral therapies are prescribed . Typical antibiotics used are cefoxitin or cefotetan plus doxycycline, and clindamycin plus gentamicin. An alternative parenteral regimen is ampicillin/sulbactam plus doxycycline. Once infection has been eliminated, surgery may be successful in opening the lumen of the fallopian tubes to allow a successful pregnancy and birth.

Ovarian pregnancies are rare: the vast majority of ectopic pregnancies occur in the fallopian tube; only about 0.15-3% of ectopics occur in the ovary. The incidence has been reported to be about 1:3,000 to 1:7,000 deliveries.

Parametritis is an inflammation of the parametrium (connective tissue adjacent to the uterus).

It is considered a form of pelvic inflammatory disease.

Parametritis is inflammation of the ligaments around the uterus. Parametritis is different from perimetritis which is inflammation of the serosa surrounding the uterus.

Over one million cases of acute salpingitis are reported every year in the US, but the number of incidents is probably larger, due to incomplete and untimely reporting methods and that many cases are reported first when the illness has gone so far that it has developed chronic complications. For women age 16–25, salpingitis is the most common serious infection. It affects approximately 11% of females of reproductive age.

Salpingitis has a higher incidence among members of lower socioeconomic classes. However, this is thought of being an effect of earlier sex debut, multiple partners, and decreased ability to receive proper health care rather than any independent risk factor for salpingitis.

As an effect of an increased risk due to multiple partners, the prevalence of salpingitis is highest for people age 15–24 years. Decreased awareness of symptoms and less will to use contraceptives are also common in this group, raising the occurrence of salpingitis.

Endometrosis is a chronic degenerative syndrome of the lining of the uterus (the endometrium) in mares. The cause is unknown, but the severity of endometrosis increases in parallel with the age and number of pregnancies of the mare. Endometrosis is confirmed by histological examination of an endometrial biopsy, which shows degeneration of blood vessels in the endometrium, and fibrosis of the tissue, along with the development of endometrial cysts. These changes cause subfertility; in pregnant mares, the changes in the endometrium can cause the placenta to fail, leading to miscarriage of the foal. Foals which are delivered at full term may be underdeveloped (dysmature). No effective treatment is known.

The etymology of endometrosis is from the Greek "endos" (inside), "metra" (womb) and "-osis" (disease). This term was adopted in 1992; prior to that, endometrosis was variously known as chronic degenerative endometritis, endometrial fibrosis, or chronic endometrial disease.

Adenomyosis itself can cause infertility issues, however, fertility can be improved if the adenomyosis has resolved following hormone therapies like levonorgestrel therapy. The discontinuation of medication or removal of IUD can be timed to be coordinated with fertility treatments. There has also been one report of a successful pregnancy and healthy birth following high-frequency ultrasound ablation of adenomyosis.

Preterm labour and premature rupture of membranes both occur more frequently in women with adenomyosis.

In sub-fertile women who received in-vitro fertilization (IVF), women with adenomyosis were less likely to become pregnant and subsequently more likely to experience a miscarriage. Given this, it is encouraged to screen women for adenomyosis by TVUS or MRI before starting assisted reproduction treatments (ART).

Treatment involves a course of antibiotics to cover the appropriate organisms, typically ceftriaxone plus azithromycin. Laparoscopy for lysis of adhesions may be performed for refractory pain.

Adenomyosis can only be cured definitively with surgical removal of the uterus. As adenomyosis is responsive to reproductive hormones, it reasonably abates following menopause when these hormones decrease. In women in their reproductive years, adenomyosis can typically be managed with the goals to provide pain relief, to restrict progression of the process, and to reduce significant menstrual bleeding.

With the advent of IVF which bypasses the need for tubal function a more successful treatment approach has become available for women who want to conceive. IVF has now become the major treatment for women with hydrosalpinx to achieve a pregnancy.

Several studies have shown that IVF patients with untreated hydrosalpinx have lower conception rates than controls and it has been speculated that the tubal fluid that enters the endometrial cavity alters the local environment or affects the embryo in a detrimental way. Thus, many specialists advocate that prior to an IVF attempt, the hydrosalpinx should be removed.

Early treatment of an ectopic pregnancy with methotrexate is a viable alternative to surgical treatment which was developed in the 1980s. If administered early in the pregnancy, methotrexate terminates the growth of the developing embryo; this may cause an abortion, or the developing embryo may then be either resorbed by the woman's body or pass with a menstrual period. Contraindications include liver, kidney, or blood disease, as well as an ectopic embryonic mass > 3.5 cm.

Also, it may lead to the inadvertent termination of an undetected intrauterine pregnancy, or severe abnormality in any surviving pregnancy. Therefore, it is recommended that methotrexate should only be administered when hCG has been serially monitored with a rise less than 35% over 48 hours, which practically excludes a viable intrauterine pregnancy.

Ectopic gestation exists in mammals other than humans. In sheep, it can go to term, with mammary preparation to parturition, and expulsion efforts. The fetus can be removed by cesarian section. Pictures of cesarian section of a euthanized ewe, 5 days after parturition signs.

For the affected, 20% need hospitalization.

Regarding patients age 15–44 years, 0.29 per 100,000 dies from salpingitis.

However, salpingitis can also lead to infertility because the eggs released in ovulation can't get contact with the sperm. Approximately 75,000-225,000 cases of infertility in the US are caused by salpingitis. The more times one has the infection, the greater the risk of infertility. With one episode of salpingitis, the risk of infertility is 8-17%. With 3 episodes of salpingitis, the risk is 40-60%, although the exact risk depends on the severity of each episode.

In addition, damaged oviducts increase the risk of ectopic pregnancy. Thus, if one has had salpingitis, the risk of a pregnancy to become ectopic is 7 to 10-fold as large. Half of ectopic pregnancies are due to a salpingitis infection.

Other complications are:

- Infection of ovaries and uterus

- Infection of sex partners

- An abscess on the ovary

Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used first in patients with pelvic pain, particularly if the diagnosis of endometriosis has not been definitively (excision and biopsy) established. The goal of directed medical treatment is to achieve an anovulatory state. Typically, this is achieved initially using hormonal contraception. This can also be accomplished with progestational agents (i.e., medroxyprogesterone acetate), danazol, gestrinone, or gonadotropin-releasing hormone agonists (GnRH), as well as other less well-known agents. These agents are generally used if oral contraceptives and NSAIDs are ineffective. GnRH can be combined with estrogen and progestogen (add-back therapy) without loss of efficacy but with fewer hypoestrogenic symptoms. These medications are often ineffective in treating endometriomas and any relief is short lived while taking the medications. Hormonal treatment has a large number of sometimes permanent side effects, such as hot flushes, loss of bone mass, deepening of voice, weight gain, and facial hair growth.

Most studies of uterine malformations are based on populations of women who have experienced a pregnancy loss and thus do not address the issue of the prevalence in the general population. A screening study by Woelfer et al. of women without a history of reproductive problems found that about 5% of women had an arcuate uterus when they defined an arcuate uterus any fundal protrusion into the cavity that had an apical angle of more than 90 degrees. Accordingly, it was the most common uterine anomaly, followed by septate uterus (3%) and bicornuate uterus (0.5%).

A number of medications may be used to control symptoms. NSAIDs can be used to reduce painful menstrual periods. Oral contraceptive pills may be prescribed to reduce uterine bleeding and cramps. Anemia may be treated with iron supplementation.

Levonorgestrel intrauterine devices are effective in limiting menstrual blood flow and improving other symptoms. Side effects are typically few as the levonorgestrel (a progestin) is released in low concentration locally. While most levongestrel-IUD studies concentrated on treatment of women without fibroids a few reported good results specifically for women with fibroids including a substantial regression of fibroids.

Cabergoline in a moderate and well-tolerated dose has been shown in two studies to shrink fibroids effectively. The mechanism of action responsible for how cabergoline shrinks fibroids is unclear.

Ulipristal acetate is a synthetic selective progesterone receptor modulator (SPRM) that has tentative evidence to support its use for presurgical treatment of fibroids with low side-effects. Long-term UPA-treated fibroids have shown volume reduction of about 70%. In some cases UPA alone is used to relieve symptoms without surgery.

Danazol is an effective treatment to shrink fibroids and control symptoms. Its use is limited by unpleasant side effects. Mechanism of action is thought to be antiestrogenic effects. Recent experience indicates that safety and side effect profile can be improved by more cautious dosing.

Gonadotropin-releasing hormone analogs cause temporary regression of fibroids by decreasing estrogen levels. Because of the limitations and side effects of this medication, it is rarely recommended other than for preoperative use to shrink the size of the fibroids and uterus before surgery. It is typically used for a maximum of 6 months or less because after longer use they could cause osteoporosis and other typically postmenopausal complications. The main side effects are transient postmenopausal symptoms. In many cases the fibroids will regrow after cessation of treatment, however, significant benefits may persist for much longer in some cases. Several variations are possible, such as GnRH agonists with add-back regimens intended to decrease the adverse effects of estrogen deficiency. Several add-back regimes are possible, tibolone, raloxifene, progestogens alone, estrogen alone, and combined estrogens and progestogens.

Progesterone antagonists such as mifepristone have been tested, there is evidence that it relieves some symptoms and improves quality of life but because of adverse histological changes that have been observed in several trials it can not be currently recommended outside of research setting. Fibroid growth has recurred after antiprogestin treatment was stopped.

Aromatase inhibitors have been used experimentally to reduce fibroids. The effect is believed to be due partially by lowering systemic estrogen levels and partially by inhibiting locally overexpressed aromatase in fibroids. However, fibroid growth has recurred after treatment was stopped. Experience from experimental aromatase inhibitor treatment of endometriosis indicates that aromatase inhibitors might be particularly useful in combination with a progestogenic ovulation inhibitor.

For fallopian tube obstruction, alternative medicine has been used as a form of fertility treatment. A study of the use of alternative methods showed that only a minority of infertile couples utilize such treatments. It also showed that alternative methods are more often chosen by couples who were wealthier, have not yet achieved pregnancy, or had a belief in the effectiveness of such treatments. Of the study participants, 29% used a CAM modality for treatment, 22% used acupuncture, 17% used herbal therapies like Fuyan Pill, and 1% using meditation.

For most of the past century patients with tubal infertility due to hydrosalpinx underwent tubal corrective surgery to open up the distally occluded end of the tubes (salpingostomy) and remove adhesions (adhesiolysis). Unfortunately, pregnancy rates tended to be low as the infection process often had permanently damaged the tubes, and in many cases hydrosalpinges and adhesions formed again. Further, ectopic pregnancy is a typical complication. Surgical interventions can be done by laparotomy or laparoscopy.

Non-infertile patients who suffer from severe chronic pain due to hydrosalpinx formation that is not relieved by pain management may consider surgical removal of the affected tube(s) (salpingectomy) or even a hysterectomy with removal of the tubes, possibly ovaries.

Drug of choice is progesterone.

Management of dysfunctional uterine bleeding predominantly consists of reassurance, though mid-cycle estrogen and late-cycle progestin can be used for mid- and late-cycle bleeding respectively.

Also, non-specific hormonal therapy such as combined high-dose estrogen and high-dose progestin can be given. Ormeloxifene is a non-hormonal medication that treats DUB but is only legally available in India.

The goal of therapy should be to arrest bleeding, replace lost iron to avoid anemia, and prevent future bleeding.

Excessive movement before any treatments or surgeries will cause excessive bleeding.

A hysterectomy may be performed in some cases.

Because pregnancy is outside the uterus, abdominal pregnancy serves as a model of human male pregnancy or for females who lack a uterus, although such pregnancy would be dangerous.

Cases of combined simultaneous abdominal and intrauterine pregnancy have been reported.

Usage of intrauterine device (IUD) with copper requires one IUD in each horn to be effective in case of bicornuate uterus. The same practice is generally applied when using IUD with progestogen due to lack of evidence of efficacy with only one IUD.

Evidence is lacking regarding progestogen IUD usage for menorrhagia in bicornuate uterus, but a case report showed good effect with a single IUD.

Patients with a unicornuate uterus may need special attention during pregnancy as pregnancy loss, fetal demise, premature birth, and malpresentation are more common. It is unproven that cerclage procedures are helpful.

A pregnancy in a rudimentary horn cannot be saved and needs to be removed with the horn to prevent a potentially fatal rupture of the horn and uterus.

Although it is unclear whether interventions before conception or early in pregnancy such as resection of the rudimentary horn and prophylactic cervical cerclage decidedly improve obstetrical outcomes, current practice suggests that such interventions may be helpful.

Laparoscopic surgical approaches include of ovarian adhesions and of endometriomas. Endometriomas frequently require surgical removal and excision is considered to be superior in terms of permanent removal of the disease and pain relief. Surgery can sometimes have the effect of improving fertility but can have the adverse effect of leading to increases in cycle day 2 or 3 FSH for many patients.

Laser surgery and cauterization are considered to be far less effective and only burn the top layer of endometrial tissue, allowing for the endometrioma and endometriosis to grow back quickly. Likewise, endometrioma drainage or sclerotherapy are somewhat controversial technique for removing endometriomas with varied degrees of success. Conservative surgery can be performed to preserve fertility in younger patients but as earlier stated can have the effect of raising FSH values and making the ovaries less productive, especially if functional ovarian tissue is removed in the surgical process.
