Singapore Zoo has welcomed Ayaan, a male Sumatran orangutan born via caesarean section on March 18, 2026 following a high-risk pregnancy complicated by placenta praevia.
The birth is believed to be the first documented orangutan caesarean case in which both mother and infant survived. After two months of recovery, Ayaan and his mother, Chomel, have returned to the orangutan exhibit.
Ayaan is the first offspring of Charlie, a 48-year-old Sumatran orangutan whose genetic line was previously unrepresented in the managed population. The birth followed years of planning under the Southeast Asian Zoos and Aquariums Association Species Management Programme, including three artificial insemination attempts.
Mandai Wildlife Group said the case contributes to veterinary knowledge due to the rarity of caesarean births in orangutans. Sumatran orangutans are listed as Critically Endangered on the IUCN Red List.
“Ayaan’s birth is the result of years of careful planning and teamwork behind the scenes,” said Cheng Wen-Haur, deputy CEO of life sciences and chief life sciences officer at Mandai Wildlife Group. “This reflects the value of science-led, collaborative breeding programmes in safeguarding critically endangered species for the long term.”
