pheromones
Interesting information. Pheromonally induced alterations in gonadotropin releasing hormone (GnRH) pulsatility allow for a life­long causal linkage among olfaction, neurotransmission, autonomic responses, luteinizing hormone/follicle stimulating hormone ratios, steroidogenesis, neurotransmission, and hormonally induced behavioral changes. Evidence from human studies that suggests we produce and that we are not exempt from prenatally­predisposed mammalian olfactory­genetic­neuronal­hormonal relationships involving pheromones, genes in GnRH neurosecretory neurons, and the influence of GnRH secretion on levels of other hormones
