Research Progress on the Effects of Natural Products on Animal Reproduction
Natural products are derived from the components of plants,animals and microorganisms,or the metabolic components and various endogenous chemical components in organisms,mainly including plant natural products,animal natural products and microbial natural products.Natural products have a regulatory effect on animal reproductive traits.For male reproduction,natural products mainly affect spermatogenesis,sperm motility and sexual activity,in which the natural products that promote male animal reproduction include icariin,lycium barbarum polysaccharide,tribulus terrestris saponins and so on,while cannabis extract,neem,and so on have a negative impact on male reproduction.Concerning female reproduction,natural products mainly affect oogenesis,follicular development and fetal growth and development.Tea polyphenols,resveratrol,genistein,forest frog oil and other natural products can increase female reproductive capacity,while citrinin,curcumin,and other natural products can decrease female prolificacy.Hormones in natural product have the greatest influence on the reproduction of female animals,which involved in various stages from oogenesis to embryo development.During pregnancy,natural products absorbed by the mother will have certain effects on fetal development.The author mainly reviews the effects of natural products on animal reproduction,in order to provide a reference for the application of natural products in the regulation of animal reproduction.
