Although problems in animal breeding are innumerable, infertility is one of the major bottlenecks in livestock production. In this paper functional causes of infertility like luteal deficiency due to abnormal pattern of LH pulses, cystic ovarian disease, and ovulatory defects, persistent corpus luteum, infertility associated with anestrus, non-detected estrus and repeat breeder are presented with respect to cow. It has been documented that in the management of cow, there are many times when the manipulation of normal cyclic activity ensures optimum production or is convenient for the owner by use of hormones to manipulate ovarian cyclic activity. Epitomizing under the prevailing condition increased productivity of the cow can only be achieved through success in minimizing infertility problems associated with functional cause through early diagnosis and treatment in addition to improvement of animal nutrition, health and genetic makeup.
