There are many factors that contribute to the signs of infertility. Some are:
• Venereal diseases
• Genetic abnormalities caused by environmental poisons
• A deficient diet
• Stress
• Low sperm counts or abnormal sperm
• Hormonal imbalances
Progesterone and infertility are linked through the Pill which can result in temporary infertility after having stopped taking it. Hormone imbalances induced by environmental poisons are a major factor in the infertility of many people. It is also vital for a woman to keep her body fat above 20% of her total weight, otherwise menstruation will cease.
One of the least known but commonest causes of infertility is a lack of progesterone during the second half of the monthly cycle. This is known as a ‘defective luteal phase’.
For pregnancy to occur oestrogen first builds the lining of the uterus, then after ovulation the role of progesterone is to thicken that lining ready for the fertilized egg. Inadequate progesterone reduces fertility.
Research into the causes of infertility has shown that often conception occurs in a fertile woman only to be followed by failure of the egg to embed itself in the lining. A lack of progesterone and infertility go hand in glove as this hormone is vital for pregnancy, but if the interval between ovulation and menstruation is too short (less than 12 days) it means that not enough progesterone has been produced. This could result in a miscarriage as early as the next menstruation.
So, you could be fertile whilst showing all the signs of infertility!
