The World Health Organisation is considering changing its definition of 'infertility' to include the inability to find a partner with whom to conceive a child. The controversial move would, in theory, give single men and single women without medical fertility problems the right to access fertility treatment. 

As recent news stories have revealed, NHS fertility services are already under huge strain. If the WHO's decision is confirmed, it may lead to increased pressure for the introduction of commercial surrogacy, which is currently illegal in the UK.
