Dihydrotestosterone - BLOOD TEST

DHT is critical for the development of male genitalia during development.  DHT is also important during the maturation of the penis, testicles, seminal vesicles and prostate as men develop into maturity.  Male pattern hair growth on the face, pubic, and body depend on DHT levels as well.  The enzyme 5α-reductase is used to convert testosterone into DHT. 

Levels of DHT are normally significantly less than that of testosterone in most areas of the body.  DHT is normally 1/10 to 1/20 the concentration of testosterone, however, certain tissues like the prostate can have 10 times the amount of DHT vs the rest of the body.  For this reason, it is important to check the levels of DHT to ensure the prostate is not at risk for cancer. 

  DHT is responsible for:  

  • Prostate enlargement- This is critical during puberty, however, if DHT levels stay high for too long prostate cancer risk start to increase markedly.  
  • Facial, axillary, pubic, and over all body hair growth.  
  • Scalp and forehead recession style hair loss- Male pattern balding.  This can happen in women as well if the levels of DHT get too high.
