I have not looked at this thread for quite a while. So, some updates in response to posts.

Mr Hide, you have good book learning but some is out of date. For decades we thought that precum was there to neutralize acidity. The current theory is that it is actually a lubricant that helps the glob of semen pass easily. You could also say that if a hormonal system fails because of a dietery supplement, that was not correct use. The number I give are not theoretical or advertised success rates; they are real life experiences of thousands of women reporting what happened.

Michelle, a few women do react to spermicides - not many. Two of the three most commonly used, including Non-9, are detergents. And women who react to detergent may have problems. Read the labels and you will find the ingredients. If you react to one, try one of the others. This is a trial and error effort.

As a long ago diaphragm user, I did not find them hard to use. But there are lots of jokes around about their springing around the room after they were squeezed with the jelly on the fingers. I still have some patients using them but many have replaced them with the sponge. Another idea a few patients have come up with is to use the disposable menstrual cup as a cervical cap. Not a recommendat but for women who find they fit, you do not need to see us doctors.

If a medication interferes with one hormonal form of birth control, it will interfere with all. Talk to your doctor.
