Suzie from Perth has asked me about contraception for fortysomethings, and for some women it can certainly be a bit of minefield. Although the risk of falling pregnant in your forties is greatly reduced, it can still happen. So if you are not in the market for more children, it's important to use something which will prevent an unwanted pregnancy, and which suits your changing body. And if you are newly single, you also need to protect yourself from STIs. In the chapter of my book entitled "Sex" I explore some of the various options for fortysomething women, but my expert in the field, Dr. Elizabeth Farrell, puts a vasectomy for your partner at the top of her list, followed by the new NuvaRing, progestin-only pills, and the Mirena IUD. Each option has pros and cons, however, and it's very important to be aware of them. And in the case of vasectomy, it's vitally important that you are sure you do not want children, especially if you have never had them. Don't be afraid to ask your doctor questions, and also be prepared to try several methods until you find the one which suits you the best.
