Research overview: human chorionic gonadotropin for ovulation induction in cats

Human chorionic gonadotropin mimics luteinizing hormone and is widely used to trigger ovulation in felids after follicular development has been stimulated. This overview surveys how the hormone is administered following equine or other gonadotropin priming to induce follicle maturation, and how its timing determines when eggs are released for insemination or collection. It considers species-specific responses, the risk of forming accessory or luteinized structures, and variability in ovarian sensitivity that complicates protocols in nondomestic cats. The topic is foundational to laboratory and conservation reproductive work, since predictable ovulation underpins artificial insemination, in vitro fertilization, and embryo production. Refining these regimens remains an active area aimed at improving pregnancy rates in endangered felids.
