Between 5 and 10 percent of women with POF may become pregnant. Currently no fertility treatment has officially been found to effectively increase fertility in women with POF, and the use of donor eggs with in-vitro fertilization (IVF) and adoption are popular as a means of achieving parenthood for women with POF. Some women with POF choose to live child-free. (See impaired ovarian reserve for a summary of recent randomized clinical trials and treatment methods.)

Currently New York fertility researchers are investigating the use of a mild hormone called dehydroepiandrosterone (DHEA) in women with POF to increase spontaneous pregnancy rates. Published results from studies conducted on DHEA have indicated that DHEA may increase spontaneously conceived pregnancies, decrease spontaneous miscarriage rates and improve IVF success rates in women with POF.

Additionally, over the last five years a Greek research team has successfully implemented the use of dehydroepiandrosterone (DHEA) for the fertility treatment of women suffering with POF.The majority of the patients were referred for donor eggs or surrogacy, however after a few months of DHEA administration, some succeeded in getting pregnant through IVF, IUI, IUTPI or natural conception. Many babies have been born after treatment with DHEA.

Ovarian tissue cryopreservation can be performed on prepubertal girls at risk for premature ovarian failure, and this procedure is as feasible and safe as comparable operative procedures in children.

Serum follicle-stimulating hormone (FSH) measurement alone can be used to diagnose the disease. Two FSH measurements with one-month interval have been a common practice. The anterior pituitary secretes FSH and LH at high levels due to the dysfunction of the ovaries and consequent low estrogen levels. Typical FSH in POF patients is over 40 mlU/ml (post-menopausal range).

Transvaginal ultrasonography can be used to determine antral follicle count (AFC). This is an easy-to-perform and noninvasive method (but there may be some discomfort). Several studies show this test to be more accurate than basal FSH testing for older women (< 44 years of age) in predicting IVF outcome. This method of determining ovarian reserve is recommended by Dr. Sherman J. Silber, author and medical director of the Infertility Center of St. Louis.

AFC and Median Fertile Years Remaining

Note, the above table from Silber's book may be in error as it has no basis in any scientific study, and contradicts data from Broekmans, et al. 2004 study. The above table closely matches Broekmans' data only if interpreted as the total AFC of both ovaries. Only antral follicles that were 2–10 mm in size were counted in Broekmans' study.

AFC and FSH Stimulation Recommendations for Cycles Using Assisted Reproduction Technology

Elevated serum follicle stimulating hormone (FSH) level measured on day three of the menstrual cycle. (First day of period flow is counted as day one. Spotting is not considered start of period.) If a lower value occurs from later testing, the highest value is considered the most predictive. FSH assays can differ somewhat so reference ranges as to what is normal, premenopausal or menopausal should be based on ranges provided by the laboratory doing the testing. Estradiol (E2) should also be measured as women who ovulate early may have elevated E2 levels above 80 pg/mL (due to early follicle recruitment, possibly due to a low serum inhibin B level) which will mask an elevated FSH level and give a false negative result.

High FSH strongly predicts poor IVF response in older women, less so in younger women. One study showed an elevated basal day-three FSH is correlated with diminished ovarian reserve in women aged over 35 years and is associated with poor pregnancy rates after treatment of ovulation induction(6% versus 42%).

The rates for spontaneous pregnancy in older women with elevated FSH levels have not been studied very well and the spontaneous pregnancy success rate, while low, may be underestimated due to non reporting bias, as most infertility clinics will not accept women over the age of forty with FSH levels in the premenopausal range or higher.

A woman can have a normal day-three FSH level yet still respond poorly to ovarian stimulation and hence can be considered to have poor reserve. Thus, another FSH-based test is often used to detect poor ovarian reserve: the clomid challenge test, also known as CCCT(clomiphene citrate challenge test).

Sporadic OHSS is very rare, and may have a genetic component. Clomifene citrate therapy can occasionally lead to OHSS, but the vast majority of cases develop after use of gonadotropin therapy (with administration of FSH), such as Pergonal, and administration of hCG to induce final oocyte maturation and/or trigger oocyte release, often in conjunction with IVF. The frequency varies and depends on a woman's risk factors, management, and methods of surveillance. About 5% of treated women may encounter moderate to severe OHSS. Risk factors include young age, the development of many ovarian follicles under stimulation, extreme elevated serum estradiol concentrations, the use of hCG for final oocyte maturation and/or release, the continued use of hCG for luteal support, and the occurrence of a pregnancy (resulting in hCG production).

Mortality is low, but several fatal cases have been reported.

If both partners are young and healthy and have been trying to conceive for one year without success, a visit to a physician or women's health nurse practitioner (WHNP) could help to highlight potential medical problems earlier rather than later. The doctor or WHNP may also be able to suggest lifestyle changes to increase the chances of conceiving.

Women over the age of 35 should see their physician or WHNP after six months as fertility tests can take some time to complete, and age may affect the treatment options that are open in that case.

A doctor or WHNP takes a medical history and gives a physical examination. They can also carry out some basic tests on both partners to see if there is an identifiable reason for not having achieved a pregnancy. If necessary, they refer patients to a fertility clinic or local hospital for more specialized tests. The results of these tests help determine the best fertility treatment.

Surgical exploration and of possible ovarian tissue is required for the definitive diagnosis of ORS, and treatment by excision of the remnant ovarian tissue may be performed during the same procedure. For women who are not candidates for surgery, a clinical diagnosis can be made based on the symptoms and levels (follicle-stimulating hormone and estradiol, after bilateral oophorectomy) and/or findings consistent with the presence of residual ovarian tissue. Laparoscopy and histological assessment can aid in diagnosis.

Diagnosis of infertility begins with a medical history and physical exam. The healthcare provider may order tests, including the following:

- Lab tests

- hormone testing, to measure levels of female hormones at certain times during a menstrual cycle

- day 2 or 3 measure of FSH and estrogen, to assess ovarian reserve

- measurements of thyroid function (a thyroid stimulating hormone (TSH) level of between 1 and 2 is considered optimal for conception)

- measurement of progesterone in the second half of the cycle to help confirm ovulation

- Anti-Müllerian hormone to estimate ovarian reserve.

- Examination and imaging

- an endometrial biopsy, to verify ovulation and inspect the lining of the uterus

- laparoscopy, which allows the provider to inspect the pelvic organs

- fertiloscopy, a relatively new surgical technique used for early diagnosis (and immediate treatment)

- Pap smear, to check for signs of infection

- pelvic exam, to look for abnormalities or infection

- a postcoital test, which is done soon after intercourse to check for problems with sperm surviving in cervical mucous (not commonly used now because of test unreliability)

- Hysterosalpingography or sonosalpingography, to check for tube patency

- Sonohysterography to check for uterine abnormalities.

There are genetic testing techniques under development to detect any mutation in genes associated with female infertility.

Initial diagnosis and treatment of infertility is usually made by obstetrician/gynecologists or women's health nurse practitioners. If initial treatments are unsuccessful, referral is usually made to physicians who are fellowship trained as reproductive endocrinologists. Reproductive endocrinologists are usually obstetrician/gynecologists with advanced training in reproductive endocrinology and infertility (in North America). These physicians treat reproductive disorders affecting not only women but also men, children, and teens.

Usually reproductive endocrinology & infertility medical practices do not see women for general maternity care. The practice is primarily focused on helping their women to conceive and to correct any issues related to recurring pregnancy loss.

The risk of ovarian remnant (ORS) is increased by incomplete removal of the ovarian at the time of oophorectomy. Surgical factors that contribute to incomplete removal include those that limit surgical exposure of the ovary, or compromise surgical technique. Factors may include:

- adhesions – these can limit visualization of the ovary and may also cause it to adhere to surrounding tissues. Adhesions are often present due to preexisting conditions and/or prior surgeries. In the majority of cases reported since 2007, endometriosis was the most common indication for the initial oophorectomy in patients who subsequently had ORS. Endometriosis increases the risk for functional ovarian tissue being embedded into adjacent structures, making complete excision of tissue challenging.

- Anatomic variations - unusual location of ovarian tissue, for example

- Intraoperative bleeding

- Poor surgical technique – this may include failure to obtain adequate exposure or restore adequate anatomy, or imprecise choice of incision site

Ovarian remnant (ORS) may first be considered in women who have undergone oophorectomy and have suggestive symptoms, the presence of a mass, or evidence of persistent ovarian function (by symptoms or laboratory testing). A history of oophorectomy is required, by definition, to make the diagnosis. Notes regarding the indication for the procedure and the procedure itself should be reviewed and may include prior abdominal or pelvic surgery, endometriosis, and/or poor surgical visualization. If ORS is possible, pelvic should be performed to evaluate for a pelvic mass.[1]

Gynecologic ultrasonography is the imaging modality of choice. Use of doppler ultrasound in the diagnosis has been suggested. However, doppler flow is not always absent in torsion – the definitive diagnosis is often made in the operating room.

Lack of ovarian blood flow on doppler sonography seems to be a good predictor of ovarian torsion. Women with pathologically low flow are more likely to have OT (77% vs. 29% in a study). The sensitivity and specificity of abnormal ovarian flow for OT are 44% and 92%, respectively, with a positive and negative predictive value of 78% and 71%, respectively. Specific flow features on Doppler sonography include:

- Little or no intra-ovarian venous flow. This is commonly seen in ovarian torsion.

- Absent arterial flow. This is a less common finding in ovarian torsion

- Absent or reversed diastolic flow

Normal vascularity does not exclude intermittent torsion. There may occasionally be normal Doppler flow because of the ovary's dual blood supply from both the ovarian arteries and uterine arteries.

Other ultrasonographic features include:

- Enlarged hypoechogenic or hyperechogenic ovary

- Peripherally displaced ovarian follicles

- Free pelvic fluid. This may be seen in more than 80% of cases

- "Whirlpool sign" of twisted vascular pedicle

- Underlying ovarian lesion can often be found

- Uterus may be slightly deviated towards the torted ovary.

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.

Ovarian torsion is difficult to diagnose accurately, and operation is often performed before certain diagnosis is made. A study at an obstetrics and gynaecology department found that preoperative diagnosis of ovarian torsion was confirmed in only 46% of people.

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.

Transvaginal ultrasonography has become the primary method of assessment of the health of an early pregnancy.

In non-pregnant patients who are evaluated for recurrent pregnancy loss the following tests are usually performed.

Parental chromosome testing (karyogram) is generally recommended after 2 or 3 pregnancy losses. Blood tests for thrombophilia, ovarian function, thyroid function and diabetes are performed.

A widely recognised method of estimating the risk of malignant ovarian cancer based on initial workup is the "risk of malignancy index" (RMI). It is recommended that women with an RMI score over 200 should be referred to a centre with experience in ovarian cancer surgery.

The RMI is calculated as follows:

There are two methods to determine the ultrasound score and menopausal score, with the resultant RMI being called RMI 1 and RMI 2, respectively, depending on what method is used:

An RMI 2 of over 200 has been estimated to have a sensitivity of 74 to 80%, a specificity of 89 to 92% and a positive predictive value of around 80% of ovarian cancer. RMI 2 is regarded as more sensitive than RMI 1.

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.

Follow-up imaging in women of reproductive age for incidentally discovered simple cysts on ultrasound is not needed until 5 cm, as these are usually normal ovarian follicles. Simple cysts 5 to 7 cm in premenopausal females should be followed yearly. Simple cysts larger than 7 cm require further imaging with MRI or surgical assessment. Because they are large, they cannot be reliably assessed by ultrasound alone because it may be difficult to see the soft tissue nodularity or thickened septation at their posterior wall due to limited penetrance of the ultrasound beam. For the corpus luteum, a dominant ovulating follicle that typically appears as a cyst with circumferentially thickened walls and crenulated inner margins, follow up is not needed if the cyst is less than 3 cm in diameter. In postmenopausal patients, any simple cyst greater than 1 cm but less than 7 cm needs yearly follow-up, while those greater than 7 cm need MRI or surgical evaluation, similar to reproductive age females.

For incidentally discovered dermoids, diagnosed on ultrasound by their pathognomonic echogenic fat, either surgical removal or yearly follow up is indicated, regardless of patient age. For peritoneal inclusion cysts, which have a crumpled tissue-paper appearance and tend to follow the contour of adjacent organs, follow up is based on clinical history. Hydrosalpinx, or fallopian tube dilation, can be mistaken for an ovarian cyst due to its anechoic appearance. Follow-up for this is also based on clinical presentation.

For multiloculate cysts with thin septation less than 3 mm, surgical evaluation is recommended. The presence of multiloculation suggests a neoplasm, although the thin septation implies that the neoplasm is benign. For any thickened septation, nodularity, or vascular flow on color doppler assessment, surgical removal should be considered due to concern for malignancy.

Some other blood tests are suggestive but not diagnostic. The ratio of LH (Luteinizing hormone) to FSH (Follicle-stimulating hormone), when measured in international units, is elevated in women with PCOS. Common cut-offs to designate abnormally high LH/FSH ratios are 2:1 or 3:1 as tested on Day 3 of the menstrual cycle. The pattern is not very sensitive; a ratio of 2:1 or higher was present in less than 50% of women with PCOS in one study. There are often low levels of sex hormone-binding globulin, in particular among obese or overweight women.

Anti-Müllerian hormone (AMH) is increased in PCOS, and may become part of its diagnostic criteria.

Patients with a double uterus may need special attention during pregnancy as premature birth and malpresentation are common. Cesarean section was performed in 82% of patients reported by Heinonen.

Uterus didelphys, in certain studies, has also been found associated with higher rate of infertility, miscarriage, intrauterine growth retardation, and postpartum bleed.

There is no simple and reliable way to test for ovarian cancer in women who do not have any signs or symptoms. The Pap test does not screen for ovarian cancer.

Screening is not recommended in women who are at average risk, as evidence does not support a reduction in death and the high rate of false positive tests may lead to unneeded surgery, which is accompanied by its own risks.

Ovarian cancer is usually only palpable in advanced stages. Screening is not recommended using CA-125 measurements, HE4 levels, ultrasound, or adnexal palpation in women who are at average risk. Risk of developing ovarian cancer in those with genetic factors can be reduced. Those with a genetic predisposition may benefit from screening. This high risk group has benefited with earlier detection.

Ovarian cancer has low prevalence, even in the high-risk group of women from the ages of 50 to 60 (about one in 2000), and screening of women with average risk is more likely to give ambiguous results than detect a problem which requires treatment. Because ambiguous results are more likely than detection of a treatable problem, and because the usual response to ambiguous results is invasive interventions, in women of average risk, the potential harms of having screening without an indication outweigh the potential benefits. The purpose of screening is to diagnose ovarian cancer at an early stage, when it is more likely to be treated successfully.

Screening with transvaginal ultrasound, pelvic examination, and CA-125 levels can be used instead of preventative surgery in women who have BRCA1 or BRCA2 mutations. This strategy has shown some success.

Other causes of irregular or absent menstruation and hirsutism, such as hypothyroidism, congenital adrenal hyperplasia (21-hydroxylase deficiency), Cushing's syndrome, hyperprolactinemia, androgen secreting neoplasms, and other pituitary or adrenal disorders, should be investigated.

"Fertility tourism" is the practice of traveling to another country for fertility treatments. It may be regarded as a form of medical tourism. The main reasons for fertility tourism are legal regulation of the sought procedure in the home country, or lower price. In-vitro fertilization and donor insemination are major procedures involved.

Perimenopause is a natural stage of life. It is not a disease or a disorder. Therefore, it does not automatically require any kind of medical treatment. However, in those cases where the physical, mental, and emotional effects of perimenopause are strong enough that they significantly disrupt the life of the woman experiencing them, palliative medical therapy may sometimes be appropriate.

Recurrent miscarriage in itself is associated with later development of coronary artery disease with an odds ratio of approximately 2, increased risk of ovarian cancer, increased risk of cardiovascular complications, and an increased risk of all-cause mortality of 44%, 86%, and 150% for women with a history of 1, 2, or 3 miscarriages, respectively.

Women with a history of recurrent miscarriage are at risk of developing preeclampsia in later pregnancies.

Acquired female infertility may be prevented through identified interventions:

- "Maintaining a healthy lifestyle." Excessive exercise, consumption of caffeine and alcohol, and smoking have all been associated with decreased fertility. Eating a well-balanced, nutritious diet, with plenty of fresh fruits and vegetables, and maintaining a normal weight, on the other hand, have been associated with better fertility prospects.

- "Treating or preventing existing diseases." Identifying and controlling chronic diseases such as diabetes and hypothyroidism increases fertility prospects. Lifelong practice of safer sex reduces the likelihood that sexually transmitted diseases will impair fertility; obtaining prompt treatment for sexually transmitted diseases reduces the likelihood that such infections will do significant damage. Regular physical examinations (including pap smears) help detect early signs of infections or abnormalities.

- "Not delaying parenthood." Fertility does not ultimately cease before menopause, but it starts declining after age 27 and drops at a somewhat greater rate after age 35. Women whose biological mothers had unusual or abnormal issues related to conceiving may be at particular risk for some conditions, such as premature menopause, that can be mitigated by not delaying parenthood.

- "Egg freezing." A woman can freeze her eggs preserve her fertility. By using egg freezing while in the peak reproductive years, a woman's oocytes are cryogenically frozen and ready for her use later in life, reducing her chances of female infertility.
