Androvax produces immunity against androstenedione, and the generation of antibodies against androstenedione decreases circulating levels of androstenedione.[1] In addition, since androstenedione is the major precursor of estrogens, estrogen levels are decreased as well.[1] This is thought to result in reduced negative feedback on the hypothalamic-pituitary-gonadal axis and increased gonadotropin secretion, which in turn improves fertility and fecundity.[1]
