Dr Doug Stein is a urologist from small town Florida on a mission to save the planet by “spreading the gospel of vasectomy”. Doug has performed more vasectomies than anyone – 30,000 – throughout the US, Asia, Africa and the Caribbean. The Vasectomist is a journey through these difficult and divisive issues, crossing cultural, religious and political taboos. Through this quixotic character and his highly personal encounters with men as they exit the gene pool, the film provokes a new conversation about over-population, over-consumption and the planet’s environmental tipping point.
