Infertility means not being able to become pregnant after a year of trying. (6 months for women over 35) Miscarriages are also considered infertility. There are many couples that have infertility problems, 33% infertility is traced to the female, 33% in males and the remaining due to unknown causes. If you think you may be infertile, see your doctor and have tests run on the ovaries to see if they work properly. Chances of conceiving decrease as age increases over 30. About 66% of couples are treated for infertility and go on to have babies. Factors that affect fertility include: age, stress, smoking and drinking, body weight, and health problems that cause hormonal changes. Age however seems to be the most common cause of fertility problems since the ability for a woman's ovaries to release eggs for fertilization decreases as age increases. No matter how old you are, you should speak with a medical doctor before trying to get pregnant.
These days fertility problems are hardly an issue. For minor cases often making a fertility chart of a woman's cycle or using a fertility calculator will help, and even in severe cases IVF is often successful
