RT Journal Article SR Electronic T1 Hypothalamic-pituitary-gonadotropic function in girls with premature thelarche. JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 941 OP 944 DO 10.1136/adc.55.12.941 VO 55 IS 12 A1 A M Pasquino A1 F Piccolo A1 A Scalamandre A1 M Malvaso A1 R Ortolani A1 B Boscherini YR 1980 UL http://adc.bmj.com/content/55/12/941.abstract AB Hypothalamic-pituitary-gonadotropic activity was investigated in 9 girls with premature thelarche, and compared with that in 9 healthy girls and 6 girls with true precocious puberty. The gonadotropin stimulation test with luteinising hormone-releasing hormone was used. Girls with premature thelarche showed luteinising hormone response resembling that of normal girls, and follicle-stimulating hormone (FSH) response quite similar to that of girls with precocious puberty. This suggests that in premature thelarche there is a partial activation of the diencephalic-hypophyseal-gonadal axis, which affects FSH only. Premature thelarche therefore, should be considered as one of the disorders due to altered sensitivity of the hypothalamic receptors which regulate sex maturation.
