Evaluating hormonal and barrier methodsSpec 7.7
In short
Barrier methods such as condoms and diaphragms stop sperm reaching an egg, while hormonal methods change the menstrual cycle. Hormonal methods are very effective when used correctly, but they do not protect against sexually transmitted infections and can cause side effects. Condoms do protect against these infections, but they are less effective if not used correctly.
Barrier methods such as condoms and diaphragms stop sperm reaching an egg. Hormonal methods change the menstrual cycle. To evaluate them, give advantages and disadvantages of each.
| Method | Advantages | Disadvantages |
|---|---|---|
| Hormonal (pill, patch, injection, implant) | Very effective when used correctly. Implants and injections last a long time, so there is nothing to remember each day | Do not protect against sexually transmitted infections. Can cause side effects. The pill must be taken at the right time every day |
| Barrier (condom, diaphragm) | Condoms also protect against sexually transmitted infections. No hormone side effects. Only used when needed | Less effective if not used correctly, for example a condom can split or slip. A diaphragm has to be fitted correctly |
An evaluate answer needs both sides and a conclusion. Finish with a judgement, such as which method suits a couple who also want protection from infection.
