11. * Sonography of polycystic ovary.

12. A: Polycystic ovaries, showing increased size and a smooth white surface reflecting thickening of the capsule. B: Section through polycystic ovary, showing multiple cysts with diameter < 10 mm arranged around the periphery of the ovary. The stroma is increased, and the ovary enlarged. ©The Medical Journal of Australia 2004 www.mja.com.au ISSN: 0025-729X

19. Young woman with PCOS showing facial hirsutism (A) and axillary acanthosis nigricans (B). The latter is associated with severe insulin resistance and hyperinsulinaemia and is an occasional finding in PCOS (photographs courtesy Dr John Casey, St Vincent’s Clinic, Sydney, NSW). ©The Medical Journal of Australia 2004 www.mja.com.au ISSN: 0025-729X

25. Flow diagram for the laboratory evaluation of amenorrhea. Such a scheme must be considered as an adjunct to the clinical evaluation of the patient. CAH -= congenital adrenal hyperplasia; DHEAS = dehydroepiandrosterone sulfate; FSH = follicle-stimulating hormone; HCA = hypothalamic chronic anovulation; PCO = polycystic ovary syndrome; PRL = prolactin; T = testosterone; TSH = thyroid-stimulating hormone.

46. FIG. 1. Case-control studies on myocardial infarctions associated with current use of low-dose oral contraceptives versus no current use. Odds ratios (ORs) are expressed with their 95% confidence interval. OR were adjusted for multiple confounding factors, depending on the study. The combined OR was weighted based on the variance of the ORs in each study.

47. FIG. 2. Case-control studies on ischemic strokes associated with current use of low-dose oral contraceptives versus no current use. Odds ratios (ORs) are expressed with their 95% confidence interval. OR were adjusted for multiple confounding factors, depending on the study. The combined OR was weighted based on the variance of the ORs in each study.
