"Hormonally Yours" was the second and final album from the group to present them as a duo of Siobhan Fahey and Marcella Detroit. The title of "Hormonally Yours" derived from both members being pregnant while making the album. Five singles were released from the album, including "Stay", which topped the UK Singles Chart, and is to date the group's best-selling single. An early cassette pressing of the album featured an alternate cover and font previously used on the "Goodbye Cruel World" single. Some versions like the German edition of the album appears to contain a straight mix of "Are We in Love Yet" similar to the BBC Radio live session while others feature the Chris Thomas remix, though he is credited in all releases. The UK CD version of 'Hormonally Yours' contains the 7" versions of "Goodbye Cruel World", "I Don't Care", and "Hello (Turn Your Radio On)" while the LP and MC versions contain the original album versions. The US pressing of the album also differed greatly, featuring the album versions of "Goodbye Cruel World", "I Don't Care" and "Hello (Turn Your Radio On)", another remixed version of "Are We In Love Yet", and slightly different versions of "Black Sky" and "The Trouble With Andre" with "Black Sky" not segueing into "The Trouble With Andre" like other pressings as well as a shorter version of "The Trouble With Andre" and the extended version of "Let Me Entertain You", as well as featuring a different cover on the CD edition with the titles being vertical like the cassette pressings.
