Sex Hormones
Hormone shots could be used as treatment for low sex drive
People with a low sex drive could benefit from injections of a hormone called kisspeptin, according to clinical trials that found the shots can boost sexual responses. The trials are the first to show the hormone can increase activity in brain regions linked to arousal and attraction in men and women who are distressed by their low libidos.

Sex hormone - Wikipedia
Sex hormones, also known as sex steroids, gonadocorticoids and gonadal steroids, are steroid hormones that interact with vertebrate steroid hormone receptors. The sex hormones include the androgens, estrogens, and progestogens. Their effects are mediated by slow genomic mechanisms through nuclear receptors as well as by fast nongenomic mechanisms through membrane-associated receptors and signaling cascades.
