There is no known specific treatment for this condition. Management is supportive.

Standard treatment would include surgical exploration via laparotomy. Laparoscopy may be an option if the surgeon is particularly skilled in removing ovarian neoplasms via laparoscopy intact. If the diagnosis of gonadoblastoma is certain, a bilateral salpingo-oophorectomy (BSO) should be performed to remove both the primary tumor and the dysgenic contralateral ovary. If uninvolved, the uterus should be left intact. Modern reproductive endocrinology technology allows patients post BSO to achieve pregnancy via in-vitro fertilization (IVF) with a donor egg.

Treatment for ovarian remnant (ORS) is generally indicated for women with suspected ORS who have symptoms (such as pain); have a pelvic mass; or need or desire complete removal of to decrease the risk of ovarian (for example, BRCA ). The mainstay of treatment is surgery to remove the residual ovarian tissue. Women with ORS with a pelvic mass should have appropriate evaluation for malignancy (cancer). Hormonal therapy to suppress ovarian function is an alternative treatment for those who refuse surgery, or those who are not candidates for surgery. Medications may be used to treat ORS and include GnRH agonists, danazol, or progesterone.

There is currently no cure, but some symptoms may be treated such as neuroleptics for the psychiatric problems.

Treatment of Meigs' syndrome consists of thoracentesis and paracentesis to drain off the excess fluid (exudate), and unilateral salpingo-oophorectomy or wedge resection to correct the underlying cause.

Treatment is symptomatic, and may include anti-seizure medication and special or supplemental education consisting of physical, occupational, and speech therapies.

Treatment is usually supportive treatment, that is, treatment to reduce any symptoms rather than to cure the condition.

- Enucleation of the odontogenic cysts can help, but new lesions, infections and jaw deformity are usually a result.

- The severity of the basal-cell carcinoma determines the prognosis for most patients. BCCs rarely cause gross disfigurement, disability or death .

- Genetic counseling

Medications for PCOS include oral contraceptives and metformin. The oral contraceptives increase sex hormone binding globulin production, which increases binding of free testosterone. This reduces the symptoms of hirsutism caused by high testosterone and regulates return to normal menstrual periods. Metformin is a drug commonly used in type 2 diabetes to reduce insulin resistance, and is used off label (in the UK, US, AU and EU) to treat insulin resistance seen in PCOS. In many cases, metformin also supports ovarian function and return to normal ovulation. Spironolactone can be used for its antiandrogenic effects, and the topical cream eflornithine can be used to reduce facial hair. A newer insulin resistance drug class, the thiazolidinediones (glitazones), have shown equivalent efficacy to metformin, but metformin has a more favorable side effect profile. The United Kingdom's National Institute for Health and Clinical Excellence recommended in 2004 that women with PCOS and a body mass index above 25 be given metformin when other therapy has failed to produce results. Metformin may not be effective in every type of PCOS, and therefore there is some disagreement about whether it should be used as a general first line therapy. The use of statins in the management of underlying metabolic syndrome remains unclear.

It can be difficult to become pregnant with PCOS because it causes irregular ovulation. Medications to induce fertility when trying to conceive include the ovulation inducer clomiphene or pulsatile leuprolide. Metformin improves the efficacy of fertility treatment when used in combination with clomiphene. Metformin is thought to be safe to use during pregnancy (pregnancy category B in the US). A review in 2014 concluded that the use of metformin does not increase the risk of major birth defects in women treated with metformin during the first trimester.

A 2017 review concluded that while both myo-inositol and D-chiro-inositols may regulate menstrual cycles and improve ovulation, there is a lack of evidence regarding effects on the probability of pregnancy. A 2012 and 2017 review have found myo-inositol supplementation appears to be effective in improving several of the hormonal disturbances of PCOS. A 2011 review found not enough evidence to conclude any beneficial effect from D-chiro-inositol. There is insufficient evidence to support the use of acupuncture.

Variable success rate with treatment, very few controlled studies, mostly case reports. Treatment success strongly tends to diminish with age and degree of elevation of FSH.

- Donor oocyte. Oocyte donation is the most successful method for producing pregnancy in perimenopausal women. In the UK the use of donor oocytes after natural menopause is controversial. A 1995 study reported that women age fifty or higher experience similar pregnancy rates after oocyte donation as younger women. They are at equal risk for multiple gestation as younger women. In addition, antenatal complications were experienced by the majority of patients, and that high risk obstetric surveillance and care is vital.

- Natural or Mini-IVF, but without the use of hCG to trigger ovulation, instead the GnRH agonist Synarel (nafarelin acetate) in a diluted form is taken as a nasal spray to trigger ovulation. Human chorionic gonadotropin (hCG) has a long half life and may stimulate (luteinize) small follicles prematurely and cause them to become cysts. Whereas nafarelin acetate in a nasal spray induces a short lived LH surge that is high enough to induce ovulation in large follicles, but too short lived to adversely affect small follicles. This increases the likelihood of the small follicles and oocytes therein developing normally for upcoming cycles and also allows the woman to cycle without taking a break and consequently increases the probability of conception in poor ovarian reserve women and advanced reproductive aged women.

- Pretreatment with 50 mcg ethinylestradiol three times a day for two weeks, followed by recombinant FSH 200 IU/day subcutaneously. Ethinylestradiol treatment was maintained during FSH stimulation. When at least one follicle reached 18mm in diameter and serum estradiol was greater or equal to 150 pg/ML ovulation was induced with an intramuscular injection of 10,000 IU of hCG (human chorionic gonadotropin hormone). For luteal phase support 5,000 IU of hCG was administered every 72 hours. Out of 25 patients 8 ovulated and 4 became pregnant. In the control group there were no ovulations. The patients ranged in age between 24 and 39 years with an average age of 32.7. All women had amenorrhea for at least 6 months (average 16.75 months) and FSH levels greater or equal than 40 mIU/mL (average FSH 68 mIU/ML). The researchers believe this protocol would work for women in early post menopause as well.

- Ethinylestradiol or other synthetic estrogens along with luteal phase progesterone (twice daily 200 mg vaginal suppositories) and estradiol support. Ethinylestradiol lowers high FSH levels which then, it is theorized, up regulates FSH receptor sites and restores sensitivity to FSH. Ethinylestradiol also has the advantage that it does not interfere with the measurement of serum levels of endogenous estradiol. During the luteal phase the FSH levels should be kept low for subsequent cycles, thus the phase is supplemented with 4 mg oral estradiol. Since conception may have occurred estradiol is used instead of the synthetic ethinylestradiol.

- Cyclical hormone replacement therapy.

- The following protocols have shown promise: high dose gonadoropins, flare up GnRH-a protocol (standard or microdose), stop protocols, short protocol, natural cycle or modified natural cycle and low dose hCG during the beginning of the stimulation protocol.

- Gonadotropin-releasing hormone agonist/antagonist conversion with estrogen priming (AACEP) protocol. Fisch, Keskintepe and Sher report 35% (14 out of 40) ongoing gestation in women with elevated FSH levels (all women had prior IVF and poor quality embryos); among women aged 41–42 the ongoing gestation rate was 19% (5 out of 26).

- DHEA: Recent clinical trial by the Center for Human Reproduction in New York showed significant effectiveness. Leonidas and Eudoxia Mamas report six cases of premature ovarian failure. After two to six months of treatment with DHEA (Two 25 mg capsules daily in five cases and three 25 mg capsules daily in one case.) all women conceived. One delivered via C-section, one aborted at 7 weeks and the remaining four were reported at 11 to 27 weeks gestation. Ages were from 37 to 40. FSH levels were from 30 to 112 mIU/mL. Ammenorhea ranged from 9 to 13 months. In addition, there is strong evidence that continuous micronized DHEA 25 mg TID reduces miscarriage and aneuploidy rates, especially above age 35.

- Glucocorticoid therapy. A recent (2007) randomized double blind study done in Egypt reported a statistically significant theurapeutic effect with dexamethasone pretreatment. Fifty-eight women with idiopathic premature ovarian failure and normal karyotype were divided into two groups of twenty-nine. The control group received placebo for twenty-eight days and then GnRH agonists plus gonadotropin therapy (hMG). The treatment group received dexamethasone for twenty-eight days (6 mg/ day) and then GnRH agonists plus gonadotropin therapy (hMG). (In both groups after the first twenty-eight days, and concurrent with the GnRH agonist treatment, the placebo or dexamethasone was gradually tapered off over ten days.) The treatment group had six ovulations and two pregnancies (p value of .02). The control group had three ovulations and no pregnancies.

- A combined pentoxifylline-tocopherol treatment has been reported effective in improving uterine parameters in women with POF undergoing IVF with donor oocytes (IVF-OD). Three women with uterine hormonoresistance despite high estradiol (E2) plasma levels received treatment with 800 mg pentoxifylline and 1000 IU of vitamin E for at least nine months. Three frozen-thawed embryo transfers (ETs) resulted in two viable pregnancies. Mean endometrial thickness increased from 4.9 mm (with thin uterine crosses) to 7.4 mm with nice uterine crosses. This treatment protocol has also reversed some cases of iatrogenic POF caused by full body radiation treatment.

The first line of therapy after diagnosis typically involves the administration of the combined oral contraceptive pill, medroxyprogesterone acetate or a gonadotropin-releasing hormone agonist to suppress menstruation and thereby relieve pain. Surgically, cervical agenesis has historically been treated through hysterectomy (removal of the uterus) to relieve symptoms caused by hematocolpos (the accumulation of menstrual fluid in the vagina). Other surgical methods of management involve the creation of an anastomotic connection between the uterus and vagina by neovaginoplasty or recanalization of the cervix. Outcomes in these cases are generally poor, since the natural functions of the cervix—such as mucus production and providing a barrier against ascending infection—cannot be replicated. Furthermore, the success rate of uterovaginal anastomosis is less than 50% and most patients require multiple surgeries while many develop cervical stenotis. Despite this, several pregnancies have been reported in women with cervical agenesis who underwent surgical treatment.

Most people develop symptoms of estrogen deficiency, including vasomotor flushes and vaginal dryness, both of which respond to hormone replacement therapy. There are several contraindications of estrogen supplement, including smokers over 35 years of age, uncontrolled hypertension, uncontrolled diabetes mellitus, or history of thromboemboli events.

Women younger than 40 year with primary ovarian insufficiency benefit from physiologic replacement of hormones. Most authorities recommend that this hormone replacement continue until age 50 years, the normal age of menopause. The leading hormone replacement regimen recommended involves the administration of estradiol daily by either skin patch or vaginal ring. This approach reduces the risk of pulmonary embolism and deep venous thrombosis by avoiding the first pass effect on the liver that is induced by oral estrogen therapy. To avoid the development of endometrial cancer young women taking estradiol replacement need also to take a progestin in a regular cyclic fashion. The most evidence supports the use of medroxyprogesterone acetate per day for days one through 12 of each calendar month. This will induce regular and predictable menstrual cycles. It is important that women taking this regimen keep a menstrual calendar. If the next expected menses is late it is important to get a pregnancy test. It this is positive, the woman should stop taking the hormone replacement. Approximately 5 to 10% of women with confirmed primary ovarian insufficiency conceive a pregnancy after the diagnosis without medical intervention.

The transdermal estradiol patch is commonly recommended due to several advantages. It provides the replacement by steady infusion rather than by bolus when taking daily pills. It also avoids the first-pass effect in the liver.

The prognosis is poor. Patients are usually wheelchair bound by their 20s and die by their 30s.

Hormone therapies are a topic of current research in ovarian cancer, particularly, the value of certain medications used to treat breast cancer. These include tamoxifen, letrozole, and anastrozole. Preliminary studies have showed a benefit for tamoxifen in a small number of people with advanced ovarian cancer. Letrozole may help to slow or stop growth of estrogen receptor positive ovarian cancer. Anastrozole is being investigated in postmenopausal people with estrogen receptor-positive cancer.

Research into mitigating side effects of ovarian cancer treatment is also ongoing. Radiation fibrosis, the formation of scar tissue in an area treated with radiation, may be relieved with hyperbaric oxygen therapy, but research has not been completed in this area. Treatment of ovarian cancer may also cause people to experience psychiatric difficulties, including depression. Research is ongoing to determine how counseling and psychotherapy can help people who have ovarian cancer during treatment.

Upon diagnosis, estrogen and progesterone therapy is typically commenced, promoting the development of female characteristics.

The consequences of streak gonads to a person with Swyer syndrome:

1. Gonads cannot make estrogen, so the breasts will not develop and the uterus will not grow and menstruate until estrogen is administered. This is often given transdermally.

2. Gonads cannot make progesterone, so menstrual periods will not be predictable until progestin is administered, usually as a pill.

3. Gonads cannot produce eggs so conceiving children naturally is not possible. A woman with a uterus and ovaries but without female gamete is able to become pregnant by implantation of another woman's fertilized egg (embryo transfer).

4. Streak gonads with Y chromosome-containing cells have a high likelihood of developing cancer, especially gonadoblastoma. Streak gonads are usually removed within a year or so of diagnosis since the cancer can begin during infancy.

Usually the lesion is surgically removed. Primarily, there is concern that the lesion identified in a patient could be cancerous, but there is also the risk of torsion, and possibly the development of symptoms. A stable lesion, however, could be clinically followed.

If ovarian cancer recurs, it is considered partially platinum-sensitive or platinum-resistant, based on the time since the last recurrence treated with platins: partially platinum-sensitive cancers recurred 6–12 months after last treatment, and platinum-resistant cancers have an interval of less than 6 months. Second-line chemotherapy can be given after the cancer becomes symptomatic, because no difference in survival is seen between treating asymptomatic (elevated CA-125) and symptomatic recurrences.

For platinum-sensitive tumors, platins are the drugs of choice for second-line chemotherapy, in combination with other cytotoxic agents. Regimens include carboplatin combined with pegylated liposomal doxorubicin, gemcitabine, or paclitaxel. Carboplatin-doublet therapy can be combined with paclitaxel for increased efficacy in some cases. Another potential adjuvant therapy for platinum-sensitive recurrences is olaparib, which may improve progression-free survival but has not been shown to improve overall survival. (Olaparib, a PARP inhibitor, was approved by the US FDA for use in BRCA-associated ovarian cancer that had previously been treated with chemotherapy.) For recurrent germ cell tumors, an additional 4 cycles of BEP chemotherapy is the first-line treatment for those tho have been treated with surgery or platins.

If the tumor is determined to be platinum-resistant, vincristine, dactinomycin, and cyclophosphamide (VAC) or some combination of paclitaxel, gemcitabine, and oxaliplatin may be used as a second-line therapy.

For platinum-resistant tumors, there are no high-efficacy chemotherapy options. Single-drug regimens (doxorubicin or topotecan) do not have high response rates, but single-drug regimens of topotecan, pegylated liposomal doxorubicin, or gemcitabine are used in some cases. Topotecan cannot be used in people with an intestinal blockage. Paclitaxel used alone is another possible regimen, or it may be combined with liposomal doxorubicin, gemcitabine, cisplatin, topotecan, etoposide, or cyclophosphamide. ( See also Palliative care below.)

Pain associated with ovarian cysts may be treated in several ways:

- Pain relievers such as acetaminophen, nonsteroidal anti-inflammatory drugs, or opioids.

- While hormonal birth control prevents the development of new cysts in those who frequently get them, it is not useful for the treatment of current cysts.

Since Krukenberg tumors are secondary (metastatic), management might logically be driven by identifying and treating the primary cancer. The optimal treatment of Krukenberg tumors is unclear. The role of surgical resection has not been adequately addressed but if metastasis is limited to the ovaries, surgery may improve survival. The role of chemotherapy and/or radiotherapy is uncertain but may sometimes be beneficial.

Physicians can reduce the risk of OHSS by monitoring of FSH therapy to use this medication judiciously, and by withholding hCG medication.

Cabergoline confers a significant reduction in the risk of OHSS in high risk women according to a Cochrane review of randomized studies, but the included trials did not report the live birth rates or multiple pregnancy rates. Cabergoline, as well as other dopamine agonists, might reduce the severity of OHSS by interfering with the VEGF system. A systematic review and meta-analysis concluded that prophylactic treatment with cabergoline reduces the incidence, but not the severity of OHSS, without compromising pregnancy outcomes.

The risk of OHSS is smaller when using GnRH antagonist protocol instead of GnRH agonist protocol for suppression of ovulation during ovarian hyperstimulation. The underlying mechanism is that, with the GnRH antagonist protocol, initial follicular recruitment and selection is undertaken by endogenous endocrine factors prior to starting the exogenous hyperstimulation, resulting in a smaller number of growing follicles when compared with the standard long GnRH agonist protocol.

A Cochrane review found administration of hydroxyethyl starch decreases the incidence of severe OHSS. There was insufficient evidence to support routine cryopreservation and insufficient evidence for the relative merits of intravenous albumin versus cryopreservation. Also, "coasting", which is ovarian hyperstimulation without induction of final maturation, does not significantly decrease the risk of OHSS.

Surgical treatment of ovarian torsion includes laparoscopy to uncoil the torsed ovary and possibly oophoropexy to fixate the ovary which is likely to twist again. In severe cases, where blood flow is cut off to the ovary for an extended period of time, necrosis of the ovary can occur. In these cases the ovary must be surgically removed.

Hormone replacement therapy with estrogen may be used to treat symptoms of hypoestrogenism in females with the condition. There are currently no known treatments for the infertility caused by the condition in either sex.

Treatment of OHSS depends on the severity of the hyperstimulation.

Mild OHSS can be treated conservatively with monitoring of abdominal girth, weight, and discomfort on an outpatient basis until either conception or menstruation occurs. Conception can cause mild OHSS to worsen in severity.

Moderate OHSS is treated with bed rest, fluids, and close monitoring of labs such as electrolytes and blood counts. Ultrasound may be used to monitor the size of ovarian follicles. Depending on the situation, a physician may closely monitor a women's fluid intake and output on an outpatient basis, looking for increased discrepancy in fluid balance (over 1 liter discrepancy is cause for concern). Resolution of the syndrome is measured by decreasing size of the follicular cysts on 2 consecutive ultrasounds.

Aspiration of accumulated fluid (ascites) from the abdominal/pleural cavity may be necessary, as well as opioids for the pain. If the OHSS develops within an IVF protocol, it can be prudent to postpone transfer of the pre-embryos since establishment of pregnancy can lengthen the recovery time or contribute to a more severe course. Over time, if carefully monitored, the condition will naturally reverse to normal – so treatment is typically supportive, although a woman may need to be treated or hospitalized for pain, paracentesis, and/or intravenous hydration.

Potential methods in unexplained infertility include oral ovarian stimulation agents (such as clomifene citrate, anastrozole or letrozole) as well as intrauterine insemination (IUI), intracervical insemination (ICI) and in vitro fertilization (IVF).

In women who have not had previous treatment, ovarian stimulation combined with IUI achieves approximately the same live birth rate as IVF. On the other hand, in women who have had previous unsuccessful treatment, IVF achieves a live birth rate approximately 2-3 times greater than ovarian stimulation combined with IUI.

IUI and ICI has higher pregnancy rates when combined with ovarian stimulation in couples with unexplained infertility, for IUI being 13% unstimulated and 15% stimulated, and for ICI being 8% unstimulated and 15% stimulated. However, the rate of twin birth increases substantially with IUI or ICI combined with ovarian stimulation, for IUI being 6% unstimulated and 23% stimulated, and for ICI being 6% unstimulated and 23% stimulated.

According to NICE guidelines, oral ovarian stimulation agents should not be given to women with unexplained infertility. Rather, it is recommended that in vitro fertilization should be offered to women with unexplained infertility when they have not conceived after 2 years of regular unprotected sexual intercourse. IVF avails for embryo transfer of the appropriate number of embryos to give good chances of pregnancy with minimal risk of multiple birth.

A review of randomized studies came to the result that IVF in couples with a high chance of natural conception, as compared to IUI/ICI with or without ovarian stimulation, was "more" effective in three studies and "less" effective in two studies.

There is no evidence for an increased risk of ovarian hyperstimulation syndrome (OHSS) with IVF when compared with ovarian stimulation combined with IUI.

Women with benign germ cell tumors such as mature teratomas (dermoid cysts) are cured by ovarian cystectomy or oophorectomy. In general, all patients with malignant germ cell tumors will have the same staging surgery that is done for epithelial ovarian cancer. If the patient is in her reproductive years, an alternative is unilateral salpingoophorectomy, while the uterus, the ovary, and the fallopian tube on the opposite side can be left behind. This isn't an option when the cancer is in both ovaries. If the patient has finished having children, the surgery involves complete staging including salpingoophorectomy on both sides as well as hysterectomy.

Most patients with germ cell cancer will need to be treated with combination chemotherapy for at least 3 cycles. The chemotherapy regimen most commonly used in germ cell tumors is called PEB (or BEP), and consists of bleomycin, etoposide, a platinum-based antineoplastic (cisplatin).
