Intrinsic secretory characteristics of luteinizing hormone and prolactin episodic release during pubertal development

The intrinsic characteristics of LH and prolactin (PRL) episodic secretion were evaluated in a group of 18 children (8M and 10F). The children were divided into two groups according to the Tanner stage: Group A (Tanner≤1, N=7, 3M and 4F, 6-10 year of age) and group B (Tanner 2-3, N=11, 5M and 6F, 9-11 years of age). A pulsatile study of 4 h, sampling every 10 min, was carried out in all children. LH and PRL plasma levels were assayed by IFMA and RIA respectively
