Hormone 6 can be checked on the fifth day of menstruation, at which time the woman’s basic endocrine level can be understood. Sex hormone levels fluctuate cyclically during the menstrual cycle. For women who need to check hormone 6, they need to follow the doctor’s instructions and choose the right time for the test according to their condition to avoid delays. Hormone 6 includes follicle-stimulating hormone, luteinizing hormone, estrogen, progesterone, androgen and prolactin. Because eating, mood, and activities have an effect on prolactin levels, it is common to try to have blood drawn on an empty stomach early in the morning, and you should sit still in your seat for about 10 minutes before the test. If you want to know the basic endocrine level of a woman, blood is usually drawn on the 2nd to 5th day of the menstrual cycle. If you want to find out whether a woman is ovulating or the luteal function, blood is usually drawn on the 21st to 23rd day of the menstrual cycle. For women with abnormal menstruation, suspected polycystic ovary syndrome, premature ovarian failure, or those who need to prepare for pregnancy, they should consult a doctor in a timely manner, and follow the doctor’s instructions to choose the right time to complete the sex hormone test to clarify their ovarian function status, and actively treat them under the guidance of the doctor if necessary.
