Follow-up Studies on the Effects of Serum Leptin on Puberty Development in Schoolboys / 中国医师杂志

ABSTRACT

Objective To explore the effect of serum leptin on puberty development in schoolboys.Methods 170 health schoolboys were investigated on the first spermatorrhea time and detected the levels of serum leptin, testosterone,follicle stimulating hormone (FSH), luteinizing hormone (LH). Case-controlled study was carried by multivariable logistic regression in puberty development of schoolchildren with and without spermatorrhea. Meanwhile, follow-up studies on the independent influencing factors on the puberty development were applied to this investigation in continuous two years.Results The levels of serum leptin, testosterone,FSH and LH of schoolboys with spermatorrhea were significantly higher than those of schoolboys without spermatorrhea. Multiple logistic regression analysis demonstrated that the serum leptin,testosterone, FSH, and bodyweight were the independent influence factors in puberty of the schoolboy.The levels of serum leptin,testosterone of pre-spermatorrhea schoolboys were significantly higher than schoolboys without spermatorrhea.Conclusions Serum leptin,testosterone, FSH, and bodyweight were the independent influence factors in puberty of the schoolboy.The levels of serum leptin and testosterone had obviously changed before spermatorrhea.
