Infertility is defined as the inability to conceive a pregnancy after 12 months of unprotected sexual intercourse. It affects about 1 in 6 Australian couples of reproductive age.

 

Causes of infertility involve male, female or a combination of factors. In 40% of couples the cause of infertility is attributed to a sperm factor, in another 40% the cause is found within the female reproductive system, and a third will have a combination of male and female factors.  When no cause is identified, this is unexplained infertility.
