If you have been trying for a baby for some time without success you might start to wonder if it will ever happen.
Nine percent of couples have trouble conceiving at some time.
There are some ways to improve your chance of pregnancy, but if you've been trying for a baby for a year or more, it might be time to see your doctor.
Fertility problems can be due to women or men's reproductive systems.
About one-third of infertility cases are due to male factors and one third due to female factors. Sometimes both partners have a fertility problem. In about 20 percent of cases, there is no apparent cause of infertility.
If you're a woman older than 35 and you've been trying to conceive for six months or more, it's time to get some medical advice.
Your doctor might conduct some tests on you (and your partner, if appropriate) to find out why you are not conceiving. He or she might refer you to a fertility specialist. The fertility specialist will do further testing to try to determine the cause of the problem.
Depending on the cause, your doctor or fertility specialist may suggest assisted reproductive treatment (ART).
