Question: when are dht levels highest?
Answer: Binding of circulating DHT to SHBG is highest in young males 0.5 to 2 years of age (90%) and thereafter declines to about 70% at age 15 and to 40% in young adult men (age 18) (31). The increase of SHBG that occurs with aging (approximately 1% per year) increases DHT binding in older men (32–35).
