The criterion for diagnosing infertility is the inability for a couple or person to conceive after 12 months of regular sexual intercourse without the use of contraception or birth control practices. People who do not conceive a child as quickly as they expected, may commonly experience concerns, anxiety and frustration. More often than not though, most couples will become pregnant within a year of frequent, contraceptive-free intercourse. Thus, if you have not been trying to conceive for a full year, be patient. For those who have attempted to conceive a child for more than a year, perhaps medical testing, assessment and treatments should be considered.
