Update information
March 2026: Changes have been made to align this quality standard with the updated NICE guideline on fertility problems. Statement 1 on lifestyle advice has been removed because of measurability issues. Statement 4 on semen analysis and statement 8 on the number of embryos transferred have been removed because these are now routine practice. All remaining statements have been updated to reflect changes to the guidance on fertility. Links, definitions and source guidance sections have also been updated throughout.
Minor changes since publication
September 2016: Number of cycles of in vitro fertilisation (IVF) corrected in the definitions section of statement 6.
