My wife is on her second Mirena coming up on five years. Her sex drive is through the roof! My concern however is what is it doing to my sex drive and ability to achieve a maximum erection. I can get about a 90-95% erect and maintain it as long as necessary and I am not taking any medication. Mayne it's age related? We are both in our early 40's. She is suffering from headaches, depression, back pain and we've decided it's time to get it removed. Can't seem to find anything definitive online regarding effects on male performance.
