    The best time for polycystic ovary patients to undergo sex hormone testing is on days 2-5 of the menstrual cycle. At this time, the test results can accurately reflect the basic hormone levels and help diagnose typical symptoms such as hyperandrogenism and abnormal ratio of luteinizing hormone and follicle-stimulating hormone. If menstruation is irregular or amenorrhea, the examination can be done at any time but it needs to be combined with other indicators such as ultrasound for comprehensive evaluation.

    Days 2-5 of the menstrual cycle belong to the early follicular phase. At this time, the ovaries are in a basic state, the follicles have not yet developed, and the levels of estrogen and progesterone are low. The follicle-stimulating hormone, luteinizing hormone, testosterone and other indicators detected at this time can eliminate the interference of cycle fluctuations and more accurately reflect the endocrine disorder characteristics of patients with polycystic ovary syndrome. For patients with amenorrhea, although six items of sex hormones can be detected at any time, it should be noted that progesterone may continue to be low due to long-term anovulation. This needs to be comprehensively judged in conjunction with clinical manifestations such as polycystic ovarian changes and increased body hair shown by ultrasound. Some patients also need to review progesterone levels in the second half of the menstrual cycle to evaluate whether there is ovulation disorder.

    It is recommended to avoid strenuous exercise, sexual intercourse, and vaginal medication for 3 days before the examination, and blood collection should be done at 9-11 a.m. after fasting for 8 hours. It is necessary to maintain a regular daily schedule, control weight within a reasonable range, reduce high-sugar and high-fat diet intake, and appropriately supplement vitamin D and inositol to help improve insulin resistance and hormone levels. If polycystic ovary syndrome is diagnosed, hormone levels should be checked regularly and treated with medication as directed by your doctor.
