I struggle with very low libido. where it is affecting my marriage. please help?

Doctor can help: One's primary care doctor can help. The issues around low libido are usually a combination of hormonal and psychological issues. There are countless products out there advertised and being sold to help improve libido, but they are almost always just loud claims and are lacking in scientific research and safety studies. That means it's best to stay away from those supplements or "libido aids."
