Sexual relationships appear to begin earlier nowadays, but sexual intercourse is in fact fairly infrequent and so permanent contraception may not be required, even though it is the most effective method, and this is the aim. The author concludes that there is no "best choice", but that in each case one has to try to use what is "least undesirable".
如今，恋爱关系似乎开始得更早，但实际上性交并不常见，因此即便长效避孕是最有效的方法，且这也是目标，但可能并不需要。作者总结说，不存在“最佳选择”，而是在每种情况下都必须尽量采用“最可接受”的方法。
