Testing will determine if your testosterone level is abnormal. This may help to explain difficulty getting an erection (erectile dysfunction) and/or the inability of your partner to get pregnant (infertility). It can also be used to indicate premature or delayed puberty if you are male, or the appearance of masculine physical features if you are female.
If you are male and you think that you may be infertile or if you are unable to get or maintain an erection you should consider testing. Also boys with either early or delayed sexual maturity should consider testing. Females that have male traits, such as a low voice or excessive body hair, or are infertile should consider testing as well.
