Junnar forest division in Maharashtra has released two radio-collared female leopards into the wild after administering immunocontraceptive drugs in India's first field trial of the method on big cats. Forest officials will track the animals' movements, behaviour and hormonal changes over the next two-and-a-half years to determine whether the reversible, vaccine-based treatment can prevent conception and help manage leopard populations in conflict-prone areas.

The pilot project received approval from the Union Ministry of Environment, Forest and Climate Change under the Wildlife (Protection) Act, 1972. The Wildlife Institute of India and the Indian Council of Medical Research are collaborating with the forest department. Between 2000 and 2025, leopard attacks killed 56 people in the Junnar forest division, while forest department records show 22 deaths and 16,593 cattle killed since 2021. The study aims to develop a uniform framework and standard operating procedure for immunocontraception that could be applied nationwide.
Times of India leads with the human-wildlife conflict toll, 22 deaths and 16,593 cattle killed since 2021, and frames the trial as a response to that pressure. Hindustan Times similarly leads with the pilot study but emphasises the two-and-a-half year monitoring period and the formal approval process from December 2023 to November 2025. Down To Earth adds political context: 56 deaths from 2000 to 2025 and election pledges in 2024, but omits the recent cattle toll. All three sources agree on the core facts, two female leopards released after immunocontraception, ICMR involvement, and MoEFCC approval under the Wildlife Act, but differ on the timeline: Hindustan Times gives 20 days ago, Times of India and Down To Earth say two weeks. The sources concur that the study's success turns on whether the treated leopards conceive after mating.
