Disease description:
Over the past two months, my menstrual flow has significantly decreased, and my emotions have also become particularly unstable, with a tendency toward irritability. I would like to undergo an endocrine examination to check my sex hormone levels. When is the best day of the menstrual cycle to perform the six sex hormone tests?

The optimal time for the six sex hormone tests is usually on the 2nd to 3rd day after the onset of a woman's menstrual period. This timeframe corresponds to the early follicular phase and can more accurately reflect the functional status of the ovaries. The six sex hormone tests are primarily performed to evaluate female endocrine function and diagnose diseases related to hormonal imbalances. These six tests include follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, testosterone, and prolactin. If a woman has long-term amenorrhea and urgently needs to obtain test results, the tests can be performed at any time, and the results will be interpreted based on reference values for the luteal phase. Before undergoing the tests, women should avoid strenuous exercise, maintain regular作息 (作息 should be translated as "daily routine" or "lifestyle habits"), refrain from sexual intercourse for three days prior to the test, and fast after 8 p.m. on the day before the test to ensure the accuracy of the results.
