At least 1 in 6 couples need medical help to achieve a pregnancy.
As a rule of thumb, 40% of infertility is down to female issues, 40% to male issues and 20% is male/female combined.
Fertility rates decline with age, especially in the female partner.
For most women, their metabolic rate increases 15-20% during the course of a pregnancy (according to patient.co.uk).
The sperm is the smallest cell in the human body.
A sperm ejaculated today first started developing about 3 months ago.
Normal sperm production occurs just below normal body temperature, which is why the testes are in the scrotum; outside the body.
Modern diets, pollution, smoking and so on can cause oxidative stress, which can lead to DNA fragmentation, reduced fertility and may be responsible for early pregnancy loss. Read more about this here.
DNA decondensation is when the DNA is unraveled in the head of the sperm. This can be caused by taking antioxidant supplements such as Vitamin C, Vitamin E, Selenium and CoQ10. DNA decondensation means the sperm cannot fertilise an egg.
Routine sperm analysis looks at the number, motility and morphology (shape/structure) of sperm, however it cannot tell whether there is DNA fragmentation or DNA decondensation.
The ovum (egg) is the largest cell in the human body.
A woman is born with her lifetime supply of eggs, but the amount diminishes continuously.
The quality of eggs naturally starts to decline in women who are in their mid-thirties.
An important change in the quality of the egg is the frequency that genetic abnormalities called aneuploidies are found in the resulting embryos. Aneuploidy is the term to describe too few or too many chromosomes.
Eggs with aneuploidy (the wrong number of chromosomes) often do not get fertilised or the resulting embryo fails to develop or is miscarried.
By the age 40, a woman’s chance of getting pregnant naturally is less than 5% per cycle.
