Groundbreaking Caesarean birth of critically endangered Sumatran orangutan extends Ah Meng’s iconic family line.

Ayaan, Singapore Zoo’s first orangutan born through artificial insemination and a rare Caesarean section, is making his public debut, marking a global milestone in great-ape veterinary care and conservation.

Pioneering Birth: AI, Placenta Praevia And A Rare C-Section
Male Sumatran orangutan Ayaan was delivered by Caesarean section on March 18 after his mother, Chomel, developed placenta praevia, where the placenta covers the birth canal and risks severe bleeding. Mandai Wildlife Group believes this is the first documented orangutan case worldwide in which an AI conception, placenta praevia and C-section all culminated in both mother and infant surviving. It is also Singapore Zoo’s first successful orangutan birth via artificial insemination and its first C-section on the species.

Saving A Vanishing Genetic Line
Ayaan’s story began in 2018 with his father, Charlie, a 48-year-old Sumatran orangutan whose genetic profile was unrepresented in the managed population. The SEAZA Species Management Programme, co-coordinated by Mandai Wildlife Group, recommended pairing Charlie with Chomel, but despite multiple attempts since 2018 he showed little interest and no natural conception occurred. With no living descendants under Charlie’s name, the team turned to assisted reproduction, attempting AI three times – in May 2022, March 2023 and July 2025. The third procedure succeeded, preserving a genetic line that would otherwise have been lost.

High-Risk Pregnancy And The “Longest Seven Minutes”
Chomel’s pregnancy was stable until January 2026, when two episodes of significant bleeding led to the placenta praevia diagnosis. Drawing on her previous gestation, the team planned a March C‑section and spent two months preparing, bringing in an external veterinary surgeon and consulting human obstetric and neonatal specialists. They even pre-identified a blood donor – her cousin and foster daughter, also named Ah Meng. On March 18, at 233 days’ gestation, Ayaan was delivered within 20 minutes, but emerged with low oxygen, a weak heart rate and hypothermia. The “baby team” stabilised him within seven tense minutes, placing him in an incubator while Chomel recovered. When she awoke and immediately embraced him, staff were reassured they had made the right call.

Supermum Chomel Extends Ah Meng’s Legacy
Two months later, Chomel is raising not one but two infants. In April, keepers placed Lio – the newborn of first-time Bornean orangutan mother Niu Li, who struggled to nurse – with Chomel, who accepted him without hesitation. Chomel is the granddaughter of Singapore Zoo icon Ah Meng, the Sumatran orangutan who captivated visitors for more than 40 years; Ayaan’s arrival extends that lineage. Her strong maternal history – having raised her own offspring Bino and Putra and adopted Khansa and the younger Ah Meng – was one reason she was chosen as Charlie’s AI partner and trusted for this risky pregnancy.

SMRT Adoption And Public Viewing Plans
Ayaan, whose name means “blessing” in Arabic, was symbolically adopted by SMRT Corporation on May 20 at a ceremony at the orangutan exhibit. SMRT’s group chief sustainability officer, Margaret Teo, said the adoption supports Mandai Wildlife Group’s efforts to protect critically endangered species as part of Singapore’s ESG and biodiversity goals. To give Chomel space as a nursing mother, Mandai has arranged a rotational exhibit schedule: Chomel, Ayaan and Lio will be on view from Thursday to Sunday and public holidays, while males Charlie and Riau are visible from Monday to Wednesday. The birth adds momentum to conservation for Sumatran orangutans, which are listed as critically endangered by the IUCN due to habitat loss, illegal pet trade and human–wildlife conflict.

Ayaan’s survival and debut represent a rare convergence of advanced reproductive science, high‑risk surgery and deep trust built between keepers and apes, while preserving a valuable genetic line and extending the legacy of Ah Meng’s family. For Indonesians and Singaporeans, his story underscores how modern zoos can contribute to regional orangutan conservation, blending veterinary innovation, long-term animal care and corporate support to safeguard a species on the brink.
