Most people will have the strong desire to conceive a child at some point during their lifetime. Understanding what defines normal fertility is crucial to helping a person, or couple, know when it is time to seek help. Most couples (approximately 85%) will achieve pregnancy within one year of trying, with the greatest likelihood of conception occurring during the earlier months. Only an additional 7% of couples will conceive in the second year. As a result, infertility has come to be defined as the inability to conceive within 12 months. Infertility happens when a couple cannot conceive after having regular unprotected sex.
It may be that one partner cannot contribute to conception, or that a woman is unable to carry a pregnancy to full term. It is often defined as not conceiving after 12 months of regular sexual intercourse without the use of birth control.
Infertility may result from an issue with either you or your partner, or a combination of factors that prevent pregnancy. Fortunately, there are many safe and effective therapies that significantly improve your chances of getting pregnant.
The main symptom of infertility is not getting pregnant. There may be no other obvious symptoms. Sometimes, a woman with infertility may have irregular or absent menstrual periods. In some cases, a man with infertility may have some signs of hormonal problems, such as changes in hair growth or sexual function.
