The natural cycle of spontaneous ovulation occurs in species such as cows. There is a great demand for ovulation to be induced in cattle as it allows farmers to synchronize their cattle to ovulate at the same time, helping improve the efficiency of dairy farming. Induced ovulation can be utilized during the warmer seasons to increase plasma progesterone and improve the fertility of the cattle. However, ovulation can only be induced in cows with mature follicles and merely initiates lutenization, it does not reduce the time for ovulation.

There are a number of methods that are used to induce ovulation in cattle such as: artificial insemination, introducing a number of hormones such as chorionic gonadotrophin,  hCG and LH. As well as injecting progesterone by intravaginal devices called PRIDs (progesterone-releasing intravaginal devices)
