Kadioglu et al. [12], using the Female Sexual Function Index (FSFI) questionnaire, observed statistically lower values of the total FSFI score and domain scores for all phases of female sexual function: desire, arousal, lubrication, orgasm, satisfaction, and pain in females with elevated prolactin levels, and this sexual dysfunction correlated negatively with circulating prolactin levels. The gene discussed is PRL; the disease is sexual dysfunction.
