Some women only become aware of their infertility when they try to fall pregnant but then find out that they cannot conceive. A lot of women don't have any infertility symptoms and others have all the symptoms and signs of infertility.

There are lots of different causes of infertility and if a woman is unable to fall pregnant it is a good idea to go and see her primary health care practitioner.

The first possible sign of infertility might be an irregular period. This is also one of the most common signs.  Unexplained obesity or below average body weight, especially if coupled with a irregular period, can also be a sign of possible infertility. Woman that are severely underweight might have infertility, or are unable to carry a pregnancy full term, problems because their bodies lack the necessarily nutritional balance. Obese woman, where the obesity is linked to a hormonal imbalance, will find that there reproductive system are affected that might lead to infertility.

Any substance abuse will affect fertility of both the male and female partner. Alcohol and other substance abuse can harm a persons reproductive systems that in some instances might be irreversible.

Following are some signs of infertility that might affect the male in the relationship.  One of the most common male infertility signs are testicles that haven't descended. Some external factors are also known causes of male infertility. The wearing of clothes that are too tight, preventing the testicles to descend, can prevent production of viable sperm. It is the accompanied overheating of the testicles that is the cause of the problems.

Instead of just assuming infertility, sometimes a small bit of information, such as finding out when the woman is ovulating and then trying to conceive during that time might be all that is needed.
