GenetikGPR54 and KiSS1, are responsible for the onset ofpuberty.The GPR54 lies dormant (inactive) for many years until it's suddenly activated by special chemicals called kisspeptins that are produced by the KiSS1 gene.The process of puberty starts when kisspeptins turn on the GPR54 gene, sending signals to your brain and triggering a chain reaction in your body.http://www.nhs.uk/Conditions/Puberty/Pages/Causes.aspxGenetik CYP17 + CYP lainnyaCYP17 mengatur biosintesis androgenblack girls start puberty earlier than white girls

Women and girls also have testosterone in their body, which is produced in small amounts by the ovaries to help maintain muscle and bone strength.Oestrodiol is the main sex hormone in girls. It's produced by the ovaries and stimulates growth of the breasts and reproductive system, and helps regulate the monthly menstrual cycle (periods).

Boys and men also have oestrodiol in their body. It's produced in small amounts by the brain and testes to help maintain bone density.

Insulin
Liver and muscles glycogen (5% of its mass)Inhibiting fats break down & signaling to store TG (Triglycerides)30Thyroid
Stimulate the development and growth of the body; Raise blood pressure; Increase heat production; Increase motor activity; Accelerate thinking; Improve mental activity; Accelerate the uptake of oxygen by all organs except spleen, testes and brain; Support the respiratory center; Increase strength and frequency of the heart rhythmic contractions; Stimulate formation of kidney hormone - erythropoietin and formation of erythrocytes; Stimulate protein digestibility

High iodine levels inhibit iodide oxidation and organification. Additionally, iodine excess inhibits thyroglobulin proteolysis (this is the principal mechanism for the antithyroid effect of inorganic iodine in patients with thyrotoxicosis).Thyrotoxicosis Hyperthyroidism

PTH & Calcitriol Ca 2+ in blood PTH secretion is controlled by Ca2+ level in serum (+ vit D n neurotransmitters)PTH Kidneys to excrete phosphate in urine Magnesium in blood Calcitonin Ca2+ in blood
Parathyroid kidneys, slows down the amount of calcium and magnesium filtered from the blood into the urine. stimulates the kidneys to make calcitriol, the active form of vitamin D. Calcitriol helps to increase the amount of calcium, magnesium and phosphorus absorbed from your intestines (guts) into the blood.37Leptin hormone

In boys, puberty is considered delayed if No testicular enlargement (14), Lack of pubic hair (15), or > 5 years are required to complete genital enlargement.Delayed SD 2/-2 dari mean (rerata)64CentralIntact hypothalamo-pituitary axis:Constitutional delay in growth and puberty (CDGP) - sporadic or familial; see also separate articleShort Stature.Chronic illness, egkidney disease,Crohn's disease.Malnutrition, eganorexia nervosa,cystic fibrosis,coeliac disease.Excessive physical exercise, particularly athletes or gymnasts.Psychosocial deprivation.Steroid therapy.Hypothyroidism.Impaired hypothalamo-pituitary axis:Tumours adjacent to the hypothalamo-pituitary axis, egcraniopharyngioma,optic glioma, germinomas, astrocytomas, pituitary tumours (includinghyperprolactinaemia).Congenital anomalies, egsepto-optic dysplasia, congenitalpanhypopituitarism.Irradiation treatment.Trauma: surgery,head injury.Gonadotrophin-releasing hormone (GnRH)/luteinising hormone (LH)/follicle-stimulating hormone (FSH) deficiency, eg congenital idiopathic,Prader-Willi syndrome,Bardet-Biedl syndrome,Kallmann's syndrome.

Puberty disorders detectionPhysical exam : Pubic hair, axillary hair, acne, oily skin/hair Phallic length and width Testicular volume Breast development Clitoromegaly, labial fusionBone ageImaging Pituitary MRI, Testicular Ultrasound, adrenal ultrasoundBloodwork pituitary hormones (LH and FSH), sex steroids, hCG and AFPEffectPrecocious Puberty :Physical deformityShort statureIf a childexperiences puberty earlier than normal it's known as early or precocious puberty. Delayed puberty is where puberty occurs later than normal.In some cases, early or delayed puberty may be caused by an underlying condition. If there's no obvious cause, such as a long-term illness, tests may be needed to help diagnose any problems.
