Women younger than 35 years of age with no obvious cause of infertility are advised to try conceiving naturally for a period of 12 months before seeking help. For women over 35 years the recommended period of trying is 6 months.
In case of any known fertility issue in either the male or female partner as well as a history of undergoing medical treatments which are known to impair fertility, seeking immediate medical help is advised to improve the chances of pregnancy.
