Abstract:
OBJECTIVESThe investigation of the testicular volume, the penis length and the T, FSH, LH, PRL levels in serum were taken in 289 adolescent males to provide the valuable data for andrology.
METHODSThe adolescent males were grouped according to their age. The testicular volume was measured with testicular model and the T, FSH, LH, PRL levels in serum were determined by immunoenzymetric assay.
RESULTSThe male sexual development was rapid from age 11 to 16 and close to that of adult at age 18. Serum PRL of adolescent males was higher than that of adult males.
CONCLUSIONSThe age 11 to 16 is a period of rapid growth in sexual maturation. PRL may play an important role in sexual maturation.
