How much more effective is using a condom with spermicide than using a condom alone in preventing pregnancy?

Thank you for your interesting question. Microgynon is a widely used contraceptive. Meaning that if you have been taking it regularly as per prescribed by your doctor, you should be protected from pregnancy. That said, even though you might be fully following the instructions, there is still a small chance of getting pregnant. This could sometimes be related to: The weight of the patient (ie > 59kg) Taking antibiotics and other medications that may interact with the Pill. If you are super paranoid about pregnancy, you can consider using 2 methods combined, or using an IUD/implanon.

Thank you for your interesting question that other readers want to know the answer to as well. In a large study of a lot of patients, the rate of pregnancy in patients receiving Ella ranged from 0. 9 to 1. 4 percent versus 2. 2 to 2. 5 percent in patients receiving postinor. Hence the short answer is 1 in 100. But in life, if you are the one, it is 100% for you. I would strongly encourage you to try to use other regular methods. Speak to your GP or Gynae.
