For anyone who has found it easy to conceive, it is perhaps hard to imagine how IVF can become all-encompassing in someone's life. The endless check-ups, scans, tests, periods of waiting and finally the day when you learn the result. It's a physically punishing process for the women and an emotionally exhausting process for both partners.
The reality is that it would be wiser and even kinder for politicians to be responsible about what they claim the NHS will do, because the pain of having raised expectations for parents who are desperate to start a family, only to see those hopes crushed, is more cruel than having said nothing at all.
