Some women benefit from a low-dose testosterone replacement to improve low sex drive. This needs to be discussed with your doctor as it is not right for everyone.
Other forms of HRT/MHT are tibolone (a type of steroid medicine) or other medicines known as SERMs (selective oestrogen receptor modulators).
