COD( polycystic ovarian disease) is one of the commonest causes of infertility. Patients have multiple small cysts in their ovaries that occur when the regular changes of a normal menstrual cycle are disrupted. The ovary is enlarged; and it produces excessive amounts of androgen and estrogenic hormones.
Polycystic ovary syndrome (PCOS), also called hyperandrogenic anovulation (HA),or Stein–Leventhal syndrome,is a set of symptoms due to a hormone imbalance in women.Signs and symptoms of PCOS include irregular or no menstrual periods, heavy periods, excess body and facial hair, acne, pelvic pain, trouble getting pregnant, and patches of thick, darker, velvety skin.Associated conditions include type 2 diabetes, obesity, obstructive sleep apnea, heart disease, mood disorders, and endometrial cancer.
PCOS is due to a combination of genetic and environmental factors.Risk factors include obesity, not enough physical exercise, and a family history of someone with the condition. Diagnosis is based on two of the following three findings: no ovulation, high androgen levels, and ovarian cysts. Cysts may be detectable by ultrasound. Other conditions that produce similar symptoms include adrenal hyperplasia, hypothyroidism, and hyperprolactinemia.
PCOS has no cure.Treatment may involve lifestyle changes such as weight loss and exercise. Birth control pills may help with improving the regularity of periods, excess hair, and acne. Metformin and anti-androgens may also help. Other typical acne treatments and hair removal techniques may be used.Efforts to improve fertility include weight loss, clomiphene, or metformin. In vitro fertilization is used by some in whom other measures are not effective.
PCOS is the most common endocrine disorder among women between the ages of 18 and 44.It affects approximately 5% to 10% of this age group.It is one of the leading causes of poor fertility.
Not everyone with PCOS has polycystic ovaries (PCO), nor does everyone with ovarian cysts have PCOS; although a pelvic ultrasound is a major diagnostic tool, it is not the only one.The diagnosis is straightforward using the Rotterdam criteria, even when the syndrome is associated with a wide range of symptoms.
The primary treatments for PCOS include: lifestyle changes, medications and surgery.
Where PCOS is associated with overweight or obesity, successful weight loss is the most effective method of restoring normal ovulation/menstruation, but many women find it very difficult to achieve and sustain significant weight loss.
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 to treat insulin resistance seen in PCOS. In many cases, metformin also supports ovarian function and return to normal ovulation.
Not all women with PCOS have difficulty becoming pregnant. For those that do, anovulation or infrequent ovulation is a common cause. Other factors include changed levels of gonadotropins, hyperandrogenemia and hyperinsulinemia Like women without PCOS, women with PCOS that are ovulating may be infertile due to other causes, such as tubal blockages due to a history of sexually transmitted diseases.
For women not responsive to clomiphene and diet and lifestyle modification, there are options available including assisted reproductive technology procedures such as controlled ovarian hyperstimulation with follicle-stimulating hormone (FSH) injections followed by in vitro fertilisation (IVF).
Though surgery is not commonly performed, the polycystic ovaries can be treated with a laparoscopic procedure called "ovarian drilling" (puncture of 4–10 small follicles with electrocautery, laser, or biopsy needles), which often results in either resumption of spontaneous ovulations or ovulations after adjuvant treatment with clomiphene or FSH.
