Fertility basics
Subfertility describes a lower-than-average monthly chance of conception without ruling natural pregnancy out. Many Australian clinicians use it interchangeably with infertility, but the word is useful because it reflects what most couples experience: pregnancy is still possible, it is simply taking longer than expected. Treatment decisions weigh how long you have been trying, your age, and whether a specific cause has been found.
Also known as: sub-fertility, reduced fertility, low fertility
