What is the normal testosterone level for a one-year-old and three-month-old child?

Patient's question:

Problem Description: Hidden penis

Doctor's answer:

9.927.8 NG/DL, testosterone is primarily produced in the interstitial cells of the male testes, while the small amount of testosterone present in female blood is a metabolite of dehydroepiandrosterone.
Increased levels are seen in idiopathic precocious puberty, adrenal cortical hyperplasia in children, and some adrenal cortical tumors. It may also be elevated in tumors of the male gonadotropin-secreting glands, choriocarcinoma during pregnancy, testicular feminization, primary hirsutism, and due to the intake of barbiturates, clomiphene (clofen), gonadotropins, and oral contraceptives.
Decreased levels are observed in Down syndrome, uremia, myotonic dystrophy, liver dysfunction, primary and secondary hypogonadism, and cryptorchidism.
Female testosterone levels are lower than those in males and fluctuate with the menstrual cycle. They decrease after rest and after a glucose load but rise after exercise. In cases of female virilization, testosterone levels can rise to over 7.0 mol/L.
Intake of androgens, dexamethasone, digoxin, and ethanol can lower test results.
