Level Of Sexual Desire

What Causes Reduced Sexual Desire?

Reduced sexual desire can have various causes, ranging in severity from 'minor' to 'life-threatening'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose reduced sexual desire, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "reduced sexual desire" as a symptom.  Here are eight of many possibilities (more below):
  • Low Testosterone
  • Hypothyroidism
  • Alcohol Consequences
  • High Histamine
  • Zinc Need
  • Low Female Testosterone
  • Low DHEA
  • Low Histamine

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
moderate alcohol consumption
poor concentration during cycle
low T3 free level
non-human estrogen use
history of occasional dieting
moderate frequency of sex
regular postprandial somnolence
major swelling at front of neck
having non-scalp scaly/flaky skin
much reduced sense of taste
numb/burning/tingling extremities
... and more than 110 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of reduced sexual desire:
Cause Probability Status
Low Testosterone 97% Confirm
Low Histamine 30% Unlikely
Zinc Need 28% Unlikely
High Histamine 5% Ruled out
Low DHEA 2% Ruled out
Alcohol Consequences 2% Ruled out
Low Female Testosterone 0% Ruled out
Hypothyroidism 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Reproductive Symptoms section of the questionnaire, The Analyst™ will ask the following question about level of sexual desire:
How strong is your sex drive (libido)? In other words, how strong is your desire for sexual activity?
Possible responses:
→ Totally absent - I am not at all interested in sex
→ Reduced
→ About average / prefer not to say / don't know
→ Increased
→ Very strong - I can't live without it!
Based on your response to this question, which may indicate absent sexual desire, weak sexual desire, strong sexual desire or very strong sexual desire, The Analyst™ will consider possibilities such as:

Mental states such as depression and strong emotions such as anger can effectively cool sexual desire.

Diabetes Type II

Lack of sexual desire can be a consequence of diabetes.


Hypothyroidism can trigger loss of libido in both men and women.

Low DHEA Level

DHEA is the precursor to testosterone.  Low testosterone levels, which reduce sex drive, may be due to low DHEA levels.

Low Male Testosterone Level

Many studies over the years have shown that testosterone is critical to sexual desire.  One of the most common symptoms of low male testosterone level is a loss of libido.

Progesterone Low or Estrogen Dominance

Loss of sex drive often correlates with a progesterone deficiency, not an estrogen deficiency.
