There is nothing inherent in engineering that precludes women from enjoying a successful career in the discipline. In fact, you will find success in engineering is based on ability and determination, not gender.
The number of women among career engineers is much lower than what most universities and companies would like to see, and large efforts are being made to invite young women to try engineering and enjoy the creativity and challenging environment that engineering offers its practitioners.
Many schools, government agencies and private companies have created programs targeted to attract women into engineering, and the participation of women in engineering has been growing -albeit quite slowly- in the last 20 years.
Today, there are more programs than ever designed to attract women into engineering as well as help them succeed in the engineering environment.
Do not let gender deter you from doing what you want to do. If you want to do it, go for it!
