A sexual dysfunction treatment apparatus for stimulating female erectile tissue, comprising: an implantable energy-consuming stimulation device, wherein the implantable stimulation device is adapted to stimulate erectile tissue to increase the amount of blood in the female erectile tissue and thereby obtaining engorgement with blood of the female erectile tissue; an implantable control unit for controlling the stimulation device to restrict the blood flow leaving the female erectile tissue and/or for controlling the stimulation device to increase the blood flow reaching the female erectile tissue, wherein the stimulation device comprises at least one from the list of: a) at least one electrical electrode for stimulating the female erectile tissue to obtain engorgement with blood of the female erectile tissue, and b) a thermal member adapted to: heat an erectile blood flow passageway of the female erectile tissue to cause expansion of a wall portion of the erectile blood flow passageway; and/or cool an erectile blood flow passageway of the female erectile tissue to cause contraction of a wall portion of the erectile blood flow passageway, wherein said treatment apparatus is characterized in that it further comprises a sensor or measuring device configured to measure at least one of: a functional parameter of the apparatus being a temperature of the stimulation device; and a physical parameter of the patient being a body temperature of the patient, wherein said control unit is adapted to control said stimulation device in response to signals from said sensor or measuring device. an implantable energy-consuming stimulation device, wherein the implantable stimulation device is adapted to stimulate erectile tissue to increase the amount of blood in the female erectile tissue and thereby obtaining engorgement with blood of the female erectile tissue;
