Oral contraceptives don’t affect women's fertility

The study led by German researchers showed that neither the length of time the pill was taken nor the type of hormones used had an affect on pregnancy rates.

In the European Active Surveillance Study on Oral Contraceptives, the researchers followed 60,000 European women for five years. Among them, 2064 admitted that they stopped using the pill because they wanted to become pregnant. The findings revealed that 21 per cent became pregnant one cycle after stopping contraceptive use.

After three cycles, the rate of pregnancy had increased to 45.7 per cent, and at one year (13 cycles) 79.4 per cent were pregnant.

On the other hand, one in five women who did not conceived in the first 12 months, 45 per cent did so in the second year (26 cycles) after stopping the pill, giving an overall success rate of 88.3 per cent.

However, researchers from Bayer Schering Pharma and ZEG-Centre for Epidemiology and Health Research in Berlin did admit that women who had been using the pill for a long time did have a slightly lower rate of pregnancy than those who had used it for a short period, but this was due to the effect of age, not long-term contraceptive use.
