Irregular or no periods
Excess hair growth.
All women with PCO have irregular or no menses. Women with PCO do not ovulate (do not release an egg every month).
Women with PCO are at a higher risk for high blood pressure, diabetes, heart disease, and uterine (endometrial) cancer. Much of this risk can be reversed by exercise and weight loss. It is also important for women with PCO to have regular periods — if a woman does not have regular periods, her risk of endometrial cancer rises — so medication is prescribed to induce regular periods.
For acne or excess hair growth, a water pill (diuretic) called spironolactone can help. For PCO women who desire pregnancy, a medication called clomiphene (CLOMID) can be used to induce ovulation (cause egg production).
A type of surgery called a “wedge resection,” in which a piece of the ovary is removed, seems to help some women.
No one is sure what causes PCO. However, the ovaries of women with PCO contain a number of small cysts. Hence, the name poly (many) cystic ovarian disease. The name “Stein-Leventhal” is after the late American gynecologists Irving F. Stein, Sr. and Michael Leo Leventhal.

- PCR (polymerase chain reaction)
PCR (polymerase chain reaction) is a technique in molecular genetics that permits the analysis of any short sequence of DNA (or RNA) even in samples containing only minute quantities of DNA or RNA. PCR is used to reproduce (amplify) selected sections of DNA or RNA for analysis. Previously, amplification of DNA involved cloning the segments […]
The familial form of PCT — is inherited as an autosomal dominant trait with males and females affected in multiple generations. The enzyme UROD is reduced in all tissues. The sporadic form of PCT — is more common. The enzyme UROD is only reduced in the liver. It appears sporadically in people with liver disease, […]

- Peak expiratory flow
Abbreviated PEF. The maximum airflow during a forced expiration beginning with the lungs fully inflated. The PEF is reduced in proportion to the severity of the airway obstruction, as in asthma and COPD (chronic obstructive pulmonary disease).
