FSFI & MSFI LIBIDO QUIZ PURPOSE
You're not alone. Taking an FSFI libido quiz or MSFI assessment might just shed some light on your sex drive. With the expertise of Dr. Diane Mueller, the Libido Doc, to guide you through TWO separate assessments — the first is a research-backed FSFI/MSFI questionnaire and if you have a low score you will be directed to the second quiz to determine what could be why your libido is low.
The FSFI (Female Sexual Function Index) and MSFI (Male Sexual Function Index) libido quiz is a tool designed to shed light on this complex aspect of your well-being. It's detailed, research-backed, and has been widely used by healthcare professionals and researchers alike.
The FSFI libido questionnaire delves into six key dimensions of sexual function: desire, arousal, lubrication, orgasm, satisfaction, and pain.

THE 5 ROOT CAUSES OF LOW DESIRE
Low libido is always a symptom, never the problem itself. The quiz identifies which of these five drivers is your dominant root cause.
HORMONAL & PHYSICAL
Testosterone, estrogen, progesterone, thyroid function, chronic pain, medication side effects — when hormones fall out of balance, libido is often the first casualty.
STRESS & NERVOUS SYSTEM OVERLOAD
A chronically activated stress response suppresses desire at the neurological level. Cortisol floods the system and the body prioritizes survival over sex.
RELATIONSHIP & EMOTIONAL DISCONNECTION
Unresolved resentment, emotional distance, or communication breakdown — when the relationship feels unsafe or disconnected, desire disappears quietly.
LIFESTYLE DEPLETION
Poor sleep, nutritional depletion, sedentary habits, alcohol, and overwork quietly erode the biological foundation of desire. You can't run desire on an empty tank.
BODY IMAGE & SELF-WORTH
Shame, self-criticism, and disconnection from your physical self are profound libido suppressors. When you're at war with your body, desire has nowhere to live.
