Using deer antler velvet benefits sexual functions and libido by helping to increase gonadotropin hormones which include luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Luteinizing hormone (LH) and follicle-stimulating hormone are hormones that stimulate the sex glands. The stimulation of the sex glands is pivotal for sexual reproduction. Without the presence of the gonadotropin hormones, the sexual organs will fail at their purpose and the individual will be considered infertile. As the deer antler velvet promotes an increase in LH, the LH causes the testes to produce more testosterone.
A systemic review on human interventions makes note of a study conducted on patients of osteoarthritis (Edelman et al. 2000; cannot be located online) which found improvements in joint pain symptoms relative to baseline in the Velvet Antler group and not placebo, although a lack of information on blinding and randomization precludes results that can be drawn from this study.
