System Biology


Better System. Better Balance.

Better Health.

Systems biology uses algorithms to measure body system balance in a holistic “real-life” forecast. We measure six Systems key to fertility health.​

As you’d expect, Cold PFPs feel colder and ‘feel the cold’ more than most other people. They also tend to be on the tired side as their lack of heat is often a reflection of body processes (the metabolic rate) being slower or lower than average. Cold PFPs are the opposite of Hot PFPs, who have faster or higher fertility metabolism.

Being mammals, we’re all relatively warm, but some of us are warmer than others and differences in warmth can be specific to parts of the body or general. Temperatures often vary around the body, especially across the lower back, and it’s worth feeling for temperature differences in your lower abdomen, middle and chest. Our temperature varies depending on:

  • Heat levels generated within cells
  • Blood circulation
  • Exposure to heat and cold
  • Sex and hormone levels
  • Diet
  • Exercise
  • Drugs
  • Our age
  • Times of day
  • Infections and inflammation

Because the lower abdomen is where our reproductive organs are, the temperature here is more important than the other parts of the body. Abnormal temperature patterns are the main issues restricting Hot and Cold PFPs’ fertility, and the PFPs can develop differently, which is useful to know when trying to raise fertility.

Variations of Cold

It’s easiest to explain these differences using the terms “Full” and “Empty”:

  • Full refers to an excess (from outside) that reduces temperatures; frostbite and a frozen shoulder from exposure to cold are examples.
  • Empty refers to a lack of heat (always internal) that causes a relative excess of cold, and hypothyroidism is a classic example.

“Full Cold”

Full Cold is relatively simple to explain, as something from the outside is chilling the body, so frostbite is the obvious example, but infections by cold viruses are another option. They make the body chilly and create stiffness, aching, and clear mucus, while other viruses (‘flu or meningitis) are more inflammatory and produce heat symptoms.

Full Cold is less of a issue nowadays, due to lifestyle changes like heated seats and central heating. Sitting on cold surfaces for too long can let cold “penetrate” into the lower abdomen and contract the tissues in the base of the penis and testes. Many of us have experienced severe cold with frozen shoulders, hands or feet, and know how it alters function and can cause pain.

The pain of Full Cold is severe and contracting and it can affect the penis, testes and upper thigh, and because cold contracts fluids, men often have erectile issues and low libido. While cold surfaces are obvious issues, poor circulation in the lower abdomen or too much chilled food and drinks make it more likely.

“Empty Cold”

Empty Cold is more subtle, as this variation of coldness develops when the body isn’t warm enough. It usually a gradual thing, without an apparent cause, until a point arrives when the relative lack of warmth and vitality becomes noticeable, usually most obviously at the end of the day or when over-tired.

Empty Cold is the issue that affects most Cold PFP men, where a low metabolic rate generates too little energy for body processes to work at their best, which means that most Cold PFPs also have Energy PFP issues.

Our bodies function best in a relatively narrow temperature range, and we become less dynamic as we get cooler. Among other things, our natural interest in sex reduces, which is pretty crucial when trying to conceive! While high temperatures create inflammation and reduce sperm quality, being too cold causes problems with semen and sperm too.

Cold affects the fluids in the glands that produce the bulk of the semen, and what may appear to be slight changes in their makeup can significantly impact male fertility. However, the main thing Cold PFP men usually notice is lower libido and sexual function. While the metabolism and hormone balance are closely linked, there are many possible causes of Empty Cold:

  1. Low thyroid hormone levels
  2. Low progesterone levels
  3. Low pituitary hormones
  4. Too much cold food and drinks
  5. A constitutional tendency to be cold
  6. Lack of exercise and activity to raise metabolism

Cold restricts and reduces movement, which encourages less activity and warmth, so the best ways to raise the temperature balance of the body is:

  • Move more.
  • Make specific diet changes.
  • Warming herbal combinations.
  • Self-help techniques.

Cold PFP and Male Fertility

As far as conceiving is concerned, being too cold affects a range of male fertility issues:

  • Low libido
  • Abnormal sperm shapes
  • Low sperm numbers
  • Poor sperm motility
  • Low testosterone levels
  • Sweaty and clammy testes
  • Urinary frequency
  • Low mood and drive
  • Lower backache
  • Loose stools
