| In vivo | In vivo studies indicate that D-Asp indirectly stimulates spermatogenesis through the hypothalamic-pituitary-gonadal axis. The oral and/or intraperitoneal D-Asp administration to adult rats induced an increase of serum progesterone and LH as well as an increase of testis/serum testosterone levels, whereas 17β-estradiol (E2) levels did no change. |
