The sex hormone test is usually done on the 3rd-5th day of menstruation, in the morning on an empty stomach, and the blood is drawn at around 9:00 a.m. Before the blood is drawn, do not do strenuous exercise and take a short rest before the blood is drawn. The hormone level measured at this time is called basal hormone level. If you are monitoring whether you are ovulating, the hormone level needs to be taken in the second half of the menstrual cycle. For different diseases, the time needed for different diagnostic purposes is different. The sex hormone 6 test is used for amenorrhea on the one hand and for the treatment of infertility patients on the other.
