Some or all of the following symptoms may be present, though it is possible not to experience any symptoms:

- Abdominal pain. Dull aching pain within the abdomen or pelvis, especially during intercourse.

- Uterine bleeding. Pain during or shortly after beginning or end of menstrual period; irregular periods, or abnormal uterine bleeding or spotting.

- Fullness, heaviness, pressure, swelling, or bloating in the abdomen.

- When a cyst ruptures from the ovary, there may be sudden and sharp pain in the lower abdomen on one side.

- Change in frequency or ease of urination (such as inability to fully empty the bladder), or difficulty with bowel movements due to pressure on adjacent pelvic anatomy.

- Constitutional symptoms such as fatigue, headaches

- Nausea or vomiting

- Weight gain

Other symptoms may depend on the cause of the cysts:

- Symptoms that may occur if the cause of the cysts is polycystic ovarian syndrome (PCOS) may include increased facial hair or body hair, acne, obesity and infertility.

- If the cause is endometriosis, then periods may be heavy, and intercourse painful.

The effect of cysts not related to PCOS on fertility is unclear.

A ruptured ovarian cyst is usually self-limiting, and only requires keeping an eye on the situation and pain medications. The main symptom is abdominal pain, which may last a few days to a several weeks, but they can also be asymptomatic. Rupture of large ovarian cysts can cause bleeding inside the abdominal cavity and in some cases shock.

It can, however, grow to almost 10 cm (4 inches) in diameter and has the potential to bleed into itself or twist the ovary, causing pelvic or abdominal pain. If it fills with blood, the cyst may rupture, causing internal bleeding and sharp pain. This pain disappears within a few days of the rupture. Rarely, it may cause the ovary to twist around the ovarian ligament and can cut off the blood flow to the ovary. This is known as ovarian torsion and causes pain and other symptoms.

If ovarian hormones are present after the ovaries are removed can be a sign that ovarian tissue still remains. Signs and symptoms may include pelvic pain, a pelvic mass, or the absence of menopause after oophorectomy. Factors may include pelvic adhesions (limiting ability to see the ovary or causing it to adhere to other tissues); anatomic variations; bleeding during surgery; or poor surgical technique. Treatment is indicated for people with symptoms and typically involves surgery to remove the residual tissue. Therapy for those who refuse surgery, cannot have surgery, or do not have a pelvic mass may include hormonal therapy to suppress ovarian function.

Some women have symptoms consistent with endometriosis, including difficult or painful intercourse; urinary symptoms; or bowel symptoms. It is likely that some women with ORS don't have any symptoms, but the rate of this is unknown.In most cases, symptoms occur within the first five years of the oophorectomy, although there are reports of ORS presenting 20 years after the initial surgery.

A Corpus luteum cyst is a type of ovarian cyst which may rupture about the time of menstruation, and take up to three months to disappear entirely. A corpus luteum cyst rarely occurs at age 50+, because eggs are no longer being released in menopausal women. Corpus luteum cysts may contain blood and other fluids. The physical shape of a corpus luteum cyst may appear as an enlargement of the ovary itself, rather than a distinct mass -like growth on the surface of the ovary.

The cause of ORS is the unintentional retention of ovarian tissue after the procedure to remove the ovaries. If a woman is receiving hormone replacement therapy, distinguishing from other disease process may be difficult. Other confounding conditions contributing to ORS are thick and profuse pelvic adhesions, inflammation, bleeding after surgery (peri-operative bleeding), and ovaries which are retroperitoneal, can all contribute to the unintentional preservation of ovarian fragments.

Patients with ovarian torsion often present with sudden onset of sharp and usually unilateral lower abdominal pain, in 70% of cases accompanied by nausea and vomiting.

Clinical symptoms of apoplexy associated with the basic mechanism of this disease:

1. Pain, which occurs primarily mid-cycle or after a minor delay in menstruation (at the time of the rupture of a corpus luteum cyst, for example). Pain is most often localized in the lower abdomen. Sometimes the pain may radiate to the rectum or to the lumbar or the umbilical region.

2. Bleeding into the abdominal cavity, which may be accompanied by:

Sometimes there may be inter-menstrual bleeding or spotting after menstruation.

Quite often, ovarian apoplexy occurs after intercourse or training in the gym, when pressure in the abdomen has increased or ovarian tissue has experienced some stress. However, rupture of ovarian tissue can occur in conjunction with other diseases.

Ovarian apoplexy is a sudden rupture in the ovary, commonly at the site of a cyst, accompanied by hemorrhage in the ovarian tissue and/or intraperitoneal bleeding.

Ovarian torsion (OT) is the rotation of the ovary at its to such a degree as to occlude the ovarian artery and/or vein.

Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. To be classified a functional cyst, the mass must reach a diameter of at least three centimeters.

These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) and are usually associated with markedly elevated levels of beta-human chorionic gonadotropin (beta-hCG). They are thus associated with gestational trophoblastic disease (molar pregnancy), diabetes mellitus, alloimmunisation to Rh-D, and multiple gestations. They have rarely been associated with chronic kidney disease (secondary to reduced hCG clearance) and hyperthyroidism (given the structural homology with TSH). These cysts resolve after pregnancy. Rarely, when the theca-lutein cysts are stimulated by gonadotropins, massive ascites can result. In most cases however, abdominal symptoms are minimal and restricted to peritoneal irritation from cyst hemorrhage. Surgical intervention may be required to remove ruptured or infarcted tissue.

Women who smoke have a twofold increase for functional cysts.

Ovarian pregnancy refers to an ectopic pregnancy that is located in the ovary. Typically the egg cell is not released or picked up at ovulation, but fertilized within the ovary where the pregnancy implants. Such a pregnancy usually does not proceed past the first four weeks of pregnancy. An untreated ovarian pregnancy causes potentially fatal intraabdominal bleeding and thus may become a medical emergency.

Ovarian diseases can be classified as endocrine disorders or as a disorders of the reproductive system.

If the egg fails to release from the follicle in the ovary an ovarian cyst may form. Small ovarian cysts are common in healthy women. Some women have more follicles than usual (polycystic ovary syndrome), which inhibits the follicles to grow normally and this will cause cycle irregularities.

Other conditions include:

- Ovarian cancer

- Luteoma

- Hypogonadism

- Hyperthecosis

The growing mass may cause pain if ovarian torsion develops. Symptoms can be caused by a mass pressing on the other abdominopelvic organs or from metastases. If these symptoms start to occur more often or more severely than usual, especially after no significant history of such symptoms, ovarian cancer is considered. Metastases may cause a Sister Mary Joseph nodule. Rarely, teratomas can cause growing teratoma syndrome or peritoneal gliomatosis. Some experience menometrorrhagia and abnormal vaginal bleeding after menopause in most cases. Other common symptoms include hirsutism, abdominal pain, virilization, and an adnexal mass.

In gynecology, a Rokitansky nodule is a mass or lump in an ovarian teratomatous cyst.

In adolescents or children with ovarian tumors, symptoms can include severe abdominal pain, irritation of the peritoneum, or bleeding. Symptoms of sex cord-stromal tumors produce hormones that can affect the development of secondary sex characteristics. Sex cord-stromal tumors in prepubertal children may be manifested by early puberty; abdominal pain and distension are also common. Adolescents with sex cord-stromal tumors may experience amenorrhea. As the cancer becomes more advanced, it can cause an accumulation of fluid in the abdomen. If the malignancy has not been diagnosed by the time it causes ascites, it is typically diagnosed shortly thereafter. Advanced cancers can also cause abdominal masses, lymph node masses, or pleural effusion.

The diagnosis is made in asymptomatic pregnant women by obstetric ultrasonography. On pelvic examination a unilateral adnexal mass may be found. Typical symptoms are abdominal pain and, to a lesser degree, vaginal bleeding during pregnancy. Patients may present with hypovolemia or be in circulatory shock because of internal bleeding.

Ideally, ultrasound will show the location of the gestational sac in the ovary, while the uterine cavity is "empty", and if there is internal bleeding, it can be identified. Because of the proximity of the tube, the sonographic distinction between a tubal and an ovarian pregnancy may be difficult. Serial hCG levels generally show not the normal progressive rise.

In a series of 12 patients the mean gestation age was 45 days.

Histologically, the diagnosis has been made by Spiegelberg criteria on the surgical specimen of the removed ovary and tube. However, the tube and ovary are not usually removed as sonography allows for earlier diagnosis and surgeons strive to preserve the ovary. Prior to the introduction of Spiegelberg's criteria in 1878, the existence of ovarian pregnancy was in doubt; his criteria helped to identify the ovarian pregnancy from other ectopics:

- The gestational sac is located in the region of the ovary.

- The gestational sac is attached to the uterus by the ovarian ligament.

- Ovarian tissue is histologically proven in the wall of the gestational sac.

- The oviduct on the affected side is intact (this criterion, however, holds not true for a longer ongoing ovarian pregnancy).

An ovarian pregnancy can be mistaken for a tubal pregnancy or a hemorrhagic ovarian cyst or corpus luteum prior to surgery. Sometimes, only the presence of trophoblastic tissue during the histologic examination of material of a bleeding ovarian cyst shows that an ovarian pregnancy was the cause of the bleeding.

Due to its classification, a dermoid cyst can occur wherever a teratoma can occur.

Dermoid cysts can appear in young children, often near the lateral aspect of the eyebrow (right part of the right eyebrow or left part of the left eyebrow). Depending on the perceived amount of risk, these are sometimes excised or simply kept under observation.

An inflammatory reaction can occur if a dermoid cyst is disrupted, and the cyst can recur if it is not completely excised. Sometimes complete excision is not practical if the cyst is in a dumbbell configuration, whereby it extends through a suture line in the skull.

If dermoid cysts appear on the medial aspect, the possibility of an encephalocele becomes greater and should be considered among the differential diagnoses.

Dermoid cysts develop during pregnancy. They occur when skin cells and things like hair, sweat glands, oil glands or fatty tissue get trapped in the skin as a baby grows in the womb.Dermoid cysts are present at birth (congenital) and are common. It can be months or years before a dermoid cyst is noticed on a child because the cysts grow slowly.

Dermoid cyst symptoms are minor and the cysts are usually painless. They are not harmful to a child’s health. If they become infected, the infection must be treated and the cyst should be removed. It is easier to remove cysts and prevent scars if the cyst is removed before it gets infected.

A cyst of Montgomery is a benign breast mass, usually found in adolescent girls. Typically, it resolves spontaneously by itself.

Most Bartholin's cysts do not cause any symptoms, although some may cause pain during walking, sitting, or sexual intercourse (dyspareunia). They are usually between 1 and 4 cm, and are located just medial to the labia minora. Most Bartholin's cysts only affect the left "or" the right side (unilateral). Small cysts are usually not painful, but very large cysts can cause significant pain.

Gynecologic hemorrhage represents excessive bleeding of the female reproductive system. Such bleeding could be visible or external, namely bleeding from the vagina, or it could be internal into the pelvic cavity or form a hematoma. Normal menstruation is not considered a gynecologic hemorrhage, as it is not excessive. Hemorrhage associated with a pregnant state or during delivery is an obstetrical hemorrhage.

The periareolar glands of Montgomery in the breast are also called Montgomery tubercles or Morgagni tubercles. These periareolar glands are small, papular tissue projections at the edge of the areola (nipple).

Obstruction of the Montgomery tubercles may result in an acute inflammation, a clear or light brownish fluid may drain out of the areola (nipple discharge), and an subareolar mass may develop, the cyst of Montgomery.

Menstruation occurs typically monthly, lasts 3–7 days, and involves up to 80 ml blood. Bleeding in excess of this norm in a nonpregnant woman constitutes gynecologic hemorrhage. In addition, early pregnancy bleeding has sometimes been included as gynecologic hemorrhage, namely bleeding from a miscarriage or an ectopic pregnancy, while it actually represents obstetrical bleeding. However, from a practical view, early pregnancy bleeding is usually handled like a gynecological hemorrhage.

A small cyst that requires magnification to be seen, may be called a microcyst. Similarly, a cyst that is larger than usual or compared to others, may be called a macrocyst.
