Deslorelin is primarily used in veterinary medicine as a reproductive management tool. It is commonly employed to induce ovulation in mares, ensuring precise timing for breeding purposes. This peptide is also utilized in controlling fertility in dogs and cats, often as part of programs to manage overpopulation or for planned breeding schedules. In human medicine, deslorelin has been explored for its potential in treating hormone-dependent conditions, such as prostate cancer and endometriosis, due to its ability to regulate gonadotropin release. Additionally, it is being investigated for use in assisted reproductive technologies to stimulate controlled ovulation in women undergoing fertility treatments.
