In clinical practice, there are two tests for women that need to be performed during menstruation: First, when performing the female sex hormone six test, it is recommended that patients have their blood drawn on an empty stomach on the second or third day of menstruation, as the female hormone level drops to the lowest on the second or third day of menstruation, and the sex hormone six test can reflect the basic endocrine situation of women. By observing the changes in hormone levels during this time period, we can more accurately determine whether the patient has ovarian function decline, or endocrine disorders such as hyperandrogenemia or polycystic ovary syndrome. Secondly, if the patient is suspected of having cervical canal adhesions, the patient’s menstrual blood cannot go down and needs to be examined during menstruation. If the woman has discomfort of lower abdomen and no menstrual blood going down during menstruation, and if the patient can be observed to have fluid in the uterine cavity by ultrasound, we should consider that the patient may have cervical canal adhesions and needs to have cervical dilatation surgery for diagnosis and treatment.
