Disease?

Just heard a BBC interview on radio 4 on women, over 34, in some areas of the UK, being refused In Vitro Fertilisation (IVF) procedures in spite of NICE suggesting that some cycles should be available to all women under 40 (https://www.bbc.co.uk/news/health-45977524). These local variations are  presumably a consequence of difficulties with funding (it's a relatively expensive procedure and not having children is not really life threatening as is the case with cancer or diabetes- although it is sad for people who really want them). Having said that, I was surprised to hear a fertility problems  referred to as a 'disease'.
