The 6 sex hormones in children are only basic screening tests and need to be combined with other tests for a comprehensive diagnosis. In general, girls mainly look at luteinizing hormone (LH), in the range of 3.0~5.1IU/L, precocious puberty may exist, while boys mainly look at testosterone (T), which exceeds the normal value indicating that precocious puberty may exist.
The 6 sex hormones in children generally include: follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), estradiol (E2), progesterone (P), and testosterone (T). In girls, the main focus is on Luteinizing Hormone (LH) and in boys, Testosterone (T).
1. Testosterone (T): It is a steroid hormone secreted by the testes in males or the ovaries in females. Among the 6 sex hormones in children, the concentration of testosterone in the blood of male children is significantly higher than that of normal children of the same age, which represents the possibility of precocious puberty.
2. Luteinizing hormone (LH): It can promote the conversion of sex hormones into sex hormones in gonadal cells. Luteinizing hormone (LH) levels between 3.0 and 5.0 IU/L may indicate the presence of precocious puberty. If the LH level is >5.0 IU/L, the gonadal axis is activated, and the diagnosis is confirmed without the need for gonadotropin-releasing hormone stimulation test.
If the above hormone levels are elevated, other tests, such as gonadotropin-releasing hormone stimulation test and imaging studies, are needed to help the doctor make the diagnosis. If the diagnosis is precocious puberty, it is necessary to actively cooperate with the doctor for treatment.
