STORY AT-A-GLANCE
- Certain aspects of the modern world, especially hormone-disrupting chemicals, are not only threatening sperm counts but also altering reproductive development in males and females
- If sperm count declines continue on the current trajectory, a significant part of the global population may not be able to reproduce without technological assistance come 2050
- Environmental chemicals that interfere with hormones — known as hormone disrupters — are at the crux of the problem; phthalates, bisphenol A, atrazine and flame retardants are among the most problematic
- Scientists are already working on how to grow life outside of a human womb and, for the first time, grew a mouse embryo in a mechanical womb for a time period equal to a human embryo at 5 weeks
- The researchers hope to use the mechanical womb to grow a human embryo to 5 weeks, raising serious ethical questions
