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.​

Temperature is the core issue for Hot PFP women, who generally feel warmer than most other people, and they also tend to be “on the go” types who find it difficult to relax at the end of the day. Their extra heat is often a reflection of their metabolic rate being higher than average, which changes the balance and rhythms of their cycles, which affects fertility.

Hot PFPs are the opposite of Cold PFPs, who have lower or slower fertility metabolism, and as mammals, we’re all relatively warm, but some of us are warmer than others. Hot PFPs can have extra heat in just a specific part of the body or it can be a more general condition. 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. The human body is designed to function within a narrow temperature range, but body temperatures vary depending on:

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

Because the lower abdomen is where our reproductive organs are, the temperature here affects fertility the most. The effects of unusual body temperature are the main issues that restrict the fertility of Hot and Cold PFPs, and there are two variations to these imbalances. Knowing which is at play is crucial when trying to increase the odds of conceiving.

Variations of Hot

It’s easiest to explain the different temperature issues using the terms “Full” and “Empty”:

  • “Full” refers to an excess (usually coming from outside) that increases temperature, and examples are meningitis or sunstroke.
  • “Empty” refers to a lack of coolness (always internal) that causes a relative excess of heat, and menopausal flushes from lower sex hormones is a classic example.

“Full Hot”

“Full Hot” is relatively simple to explain, as something from outside the body heats it up. Infections by viruses or bacteria are the usual causes, but burns are another option, and the extra heat can directly affect fertility. Sexually transmitted infections such as Chlamydia and Gonorrhoea can generate enough heat to distort and block Fallopian tubes, which reduces the chances of natural pregnancy later on.

However, anything that causes inflammation is heating, and allergies, hyper-sensitivities and autoimmune diseases have heating elements to them and change fertility levels. The signs of Full Hot are usually fairly straightforward, and they appear relatively quickly, with a hot feeling, an aversion to heat, sometimes redness, and people are often thirsty and irritable. Most forms of Full Heat only last as long as it takes the body to fight off an infection, but the immune related sensitivities can become chronic.

“Empty Hot”

“Empty Hot” is more subtle, as it develops when the body isn’t cool enough, so there’s usually a gradual, non-specific change in temperature until a point arrives when the extra warmth becomes noticeable. The extra heat tends to show up most at the end of the day or when people are over-tired. When there’s a lack heat, people feel cold, and if they lack coolness, they’ll feel hot.

Menopausal flushing is an obvious example of “empty heat”, but it’s not the only reason for night sweats and flushes, as many men experience them too. Changes in sex hormones are one reason for Empty Hot, but so are other hormone imbalances, and non-hormonal reasons exist too. The body is more likely to overreact to a fairly standard stimulus when it’s run-down, which can trigger immune system imbalances and inflammation.

Reducing exposure to triggers and generally cooling the body can make the immune system feel less “threatened” and reactive, with gradual reductions in inflammation and heat. Having a less aggressive immune system can be a crucial factor for implantation success and pregnancy health.

Hot PFP and Female Fertility

Balance is essential for a woman’s general health and fertility, and this includes temperature ranges, immune state and hormones. Having an excess of heat tends to accelerate and disrupt the menstrual cycle and reduce core aspects of female fertility, such as the depth of the womb lining and the amount of fertile mucus. Inflammation from bacterial infections is the most common cause of Fallopian tube blockages, and all inflammation shifts the hormonal balance and raises oxidative stress levels, which reduces fertility.

Identifying what’s heating Hot PFP women and stopping it from getting worse is crucial. The focus then shifts to cooling and supporting their constitution to improve egg quality as healthy eggs make healthy babies! Every menstrual cycle relies on FSH recruiting a fresh “batch” of eggs from the ovarian reserve :

  • It usually takes 13 months for eggs to reach ovulation
  • Most fail to complete the journey
  • Fewer eggs reach the final stage as women age
  • Mature egg numbers reflect ovarian reserve and oxidative stress damage
  • Damage to eggs and FSH levels can be reduced with focused changes
  • Herbal combinations are 3x more successful than IVF for unexplained infertility
