Introduction Growth hormone (GH) is a 191 amino acid protein, which binds readily to the growth hormone receptor (GHR) and in some species the prolactin receptor ( GH has been shown to have multiple specific effects in female and male reproductive physiology, such as promotion of steroidogenesis, enhancement of gonadotropin sensitivity as well as significant stimulatory effects on spermatogenesis and follicular development, which ultimately aligns with the initiation of puberty ( GH, GHR, and Follicular Growth GH has been reported by many studies to modify the growth of developing ovarian follicles ( In vitro studies using caprine preantral follicles have demonstrated the stimulatory effect of GH on antral follicle development particularly during the initial antral phase ( in vitro maturation protocols, led to the generation of healthy oocyte-cumulus complexes, production of more metaphase II oocytes, and better fertilization ability (Figure 1) ( Figure 1 The expression status of GHR mRNA at different follicle developmental stages was investigated in the goat, and high expression was found in oocyte, stromal, cumulus and mural granulosa cells of both small and large antral follicles (24)

Consequently, NMNs designation as a legal supplement was thrown into limbo, because: Per the Dietary Supplement Health and Education Act of 1994, the term dietary supplement does not include an article authorized for investigation as a new drug, antibiotic, or biological for which substantial clinical investigations have been instituted and for which the existence of such investigations has been made public.27 As an IND, NMN would have to be authorized by the FDA for administration in humans.28 In response, the Natural Products Association filed a lawsuit against the FDA based on the fact that NMN had been sold as a supplement long before the start of its IND-related studies
