In non\u2010equid species, e<jats:styled-content style=\"fixed-case\">CG<\/jats:styled-content> shows high LH\u2010 and FSH\u2010like activities and has a high affinity for both FSH and LH receptors in the ovaries. On the granulosa and thecal cells of the follicle, <jats:styled-content style=\"fixed-case\">eCG<\/jats:styled-content> has long\u2010lasting LH\u2010 and FSH\u2010like effects that stimulate oestradiol and progesterone secretion. Thus, <jats:styled-content style=\"fixed-case\">eCG<\/jats:styled-content> administration in dairy cattle results in fewer atretic follicles, the recruitment of more small follicles showing an elevated growth rate, the sustained growth of medium and large follicles and improved development of the dominant and pre\u2010ovulatory follicle. In consequence, the quality of the ensuing CL is improved, and thereby progesterone secretion increased. Based on these characteristics, <jats:styled-content style=\"fixed-case\">eCG<\/jats:styled-content> treatment is utilized in veterinary medicine to control the reproductive activity of the cow by i) improving reproductive performance during early post\u2010partum stages; ii) increasing ovulation and pregnancy rates in non\u2010cyclic cows; iii) improving the conception rate in cows showing delayed ovulation; and finally, iv) <jats:styled-content style=\"fixed-case\">eCG<\/jats:styled-content> is currently included in protocols for fixed\u2010time artificial insemination since after inducing the synchrony of ovulation using a progesterone\u2010releasing device, <jats:styled-content style=\"fixed-case\">eCG<\/jats:styled-content> has beneficial effects on embryo development and survival. The above effects are not always observed in cyclic animals, but they are evident in animals in which LH secretion and ovarian activity are reduced or compromised, for instance, during the early post\u2010partum period, under seasonal heat stress, in anoestrus animals or in animals with a low body condition
