Effect of methylphenidate hydrochloride on ovarian and pituitary gonadotropin hormone in peripubertal mice

Background and Objective: Attention deficit hyperactivity disorder (ADHD) is the most common in psychology and Methylphenidate hydrochloride (MPH) is one of the most frequently prescribed pediatric medicine. This study was done to determine the effect of Methylphenidate hydrochloride on ovarian and pituitary gonadotropin hormone in peripubertal mice Materials and Methods: This experimental study was done on 40 preipubertal female mice (BALB/c) with three weeks age and approximate 12-15 gram. The mice were allocated randomly in one control and three experimental groups, designated as I, II and III. Animals in group I, II and III were received by gavage Methylphenidate hydrochloride with 2, 5 and 10 mg/kg body weight for six days, respectively. At the end of experiment body weight, serum estrogen, progesterone and pituitary gonadotropins were measured. Morphometric and histopathological evaluation of ovary were examined. Data were analyzed using SPSS-17, ANOVA and Tukey tests. Results: The body weight and ovary dimensions of animals in experimental groups were reduced significantly in comparison with control (P
