The largest tree dwellers on the planet, orangutans mate, give birth and raise their young high in the jungle canopy. At an orangutan sanctuary in the rainforest, Mark and Joy come face-to-face with a super-male and uncover the latest scientific theories about how these kings exert their power over other males and seduce females in their territory. Joy witnesses the sneaky tactics that the females use to take control of mating and Mark finds out how males fight back. The lengthy period dedicated to raising one child is critical to the success of orangutans and all the other great apes -- including us

From PBS - Presented by anatomist Joy Reidenberg and veterinarian Mark Evans, Sex in the Wild is a four part series that explores the reproductive behaviors and biology of the animal kingdom. Focusing on four species - elephant, dolphin, kangaroo and orangutan - the series takes an in-depth look at how these animals find, fight for, and woo the opposite sex. It also explores how they mate, give birth, and raise their young in extreme environments. Why do male elephants transform into sex crazed monsters during musth? How do orangutans give birth safely high in the trees? Why is the pregnancy of kangaroos so short? And how do dolphins mate at high speed? Join Joy and Mark as they travel to Africa, Australia, New Zealand, and Borneo to explore the reproduction challenges these species face and gain fascinating insight into their worlds.
