Why can't pandas mate well in captivity?

Pandas often struggle to mate successfully in captivity due to a combination of factors, including their natural breeding behaviors and specific reproductive needs. They have a very short breeding season, typically only a few days each year, which makes timing crucial. Additionally, captive environments may not adequately replicate the conditions that encourage mating, such as the presence of natural stimuli and social interactions found in the wild. Stress and lack of familiarity with potential mates can further hinder successful reproduction.
