Dr Shanna Swan writes that humanity is facing an "existential crisis" in fertility rates as a result of phthalates, a chemical used when manufacturing plastics that impacts the hormone-producing endocrine system.

As a result of this pollution, a growing number of babies are being born with small penises, Dr Swan writes.

Her book, titled Count Down, examines "how our modern world is threatening sperm counts, altering male and female reproductive development, and imperilling the future of the human race".

Dr Swan, who is a professor in environmental medicine and public health at the Mount Sinai Hospital in New York City, based her work on a series of peer-reviewed research studies.

Dr Swan believes that the rapidly decreasing fertility rate means that most men will be unable to produce viable sperm by 2045.
