Partner getting Mirena coil fitted..no more sex?

My partner is getting a hormonal coil fitted to help manage perimenopause bleeding. Iโ€™ve had the snip so for the last year she has had no hormonal contraceptives and her libido has been great.

Reading online it sounds like this coil is going to kill her libido, in-spite of the manufacturers saying the opposite. Does anyone have and anecdotal experience about changes in their sex life after their partner has had this coil fitted?

My wife has the coil and yes, itโ€™s killed it, not that she had a particularly high libido before.
