Introduction
Normal results in the six-item sex hormone panel with delayed menstruation may be due to pregnancy. It could also result from reduced thyroid hormone secretion, which affects the endocrine system and may lead to irregular menstruation or even amenorrhea. Additionally, it might be caused by endometrial polyps, which interfere with normal endometrial thickening and cause abnormal proliferation; when the endometrium cannot be properly shed, delayed menstruation or menstrual cycle disturbances may occur.

Delayed menstruation with normal sex hormone panel results may be caused by physiological factors, or pathological factors such as hypothyroidism and endometrial polyps. The specific analysis is as follows:

I. Physiological Factors

When regular unprotected sexual intercourse occurs and menstruation is delayed, pregnancy should be considered. This is a normal phenomenon, and it is recommended to undergo regular prenatal checkups at the hospital.

II. Pathological Factors

1. Hypothyroidism

In patients with hypothyroidism, reduced secretion of thyroid hormones can disrupt the endocrine system, leading to irregular menstruation or even amenorrhea. It is recommended to take medications such as levothyroxine sodium tablets or thyroid tablets under medical guidance to improve symptoms.

2. Endometrial Polyps

Endometrial polyps can cause thickening and abnormal proliferation of the endometrium, interfering with normal shedding of the uterine lining, resulting in delayed menstruation or menstrual cycle disorders. Other symptoms may include increased menstrual flow and prolonged periods. It is recommended to undergo surgical removal of endometrial polyps at a hospital to alleviate symptoms.

In addition, delayed menstruation could also be caused by conditions such as hepatitis, polycystic ovary syndrome (PCOS), or submucosal uterine fibroids. Patients are advised to seek timely medical attention when experiencing abnormalities and receive standardized treatment under a physician’s guidance to promote recovery.
