The International Association of Professional Birth Photographers has announced the winners of their 2017 contest, and the photos they chose show the struggles mothers go through to bring new life into the world, and the sheer joy that follows.

We took your breath away with last year's contest, and these new photos will leave you even more amazed. Each one tells a story of pain, perseverance, and finally, relief. They document a baby's first moments of life, and a family's first moments of unity.

Many of the photos below are intense and graphic, so reader discretion is advised. They are all, however, powerful in their own unique ways.
