In males, what hormone is secreted by the hypothalamus that tells the anterior pituitary to secrete the gonadotropic hormones

Gonadotropin releasing hormone

Explanation:

Gonadotropin-releasing hormone is one of the releasing hormones secreted by the hypothalamus to regulate the secretion of hormones from the anterior pituitary gland.  

At the beginning of puberty, the hypothalamus begins to increase its production of gonadotropin-releasing hormone (GnRH). The gonadotropin-releasing hormone makes the anterior pituitary to release gonadotropins in both males and females. Two gonadotropic hormones are FSH (follicle-stimulating hormone) and LH (luteinizing hormone). FSH promotes spermatogenesis in the seminiferous tubules, and LH promotes androgen production in the interstitial cells.
