Final answer:
A boy learns that androgens are released into the bloodstream by the interstitial cells of Leydig in the testes during puberty, with the hypothalamus and pituitary gland orchestrating the hormonal changes that lead to increased testosterone production.
Step-by-step explanation:
A boy learning about his body would discover that androgens are released into the bloodstream by the interstitial cells of Leydig in the testes. During puberty, the hypothalamus causes the pituitary gland to release hormones such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones then act on the testes, with FSH stimulating the Sertoli cells to promote spermatogenesis and LH stimulating the Leydig cells to produce and release testosterone (an androgen) into the bloodstream.
Moreover, a decrease in the sensitivity of the hypothalamus and pituitary gland to negative feedback along with an increase in sensitivity of the gonads to FSH and LH during puberty leads to higher levels of sex steroid hormones, including testosterone. This surge in testosterone is critical for the development of male secondary sexual characteristics and the maturation of the gonads and reproductive organs.
