Abstract
Phytochemicals present in the plants are divided into primary (Alcohol Amino acids, nucleotides. etc) and secondary metabolites (Alkaloids, Saponins etc.). Carotenoids (reduces reactive oxygen species formation, decreases apoptotic cells, restoration of actin capping expression proteins etc.), Phenolics (inhibits extracellular signal-regulated kinase signalling pathway), Isoflavones (inhibits tyrosine kinase pathway) and alkaloids (downregulation of vascular endothelial growth factor, tumor necrosis factor-alpha and hypoxia-inducible factor 1-alpha messengers) are the major phytochemicals, having the potential effects towards ovarian function. Likewise, bioactive compounds are the chemicals that can interact with certain components of live tissue to exert their various effects (antioxidant, antineoplastic, receptor inhibition, gene expression etc.) respective to female fertility. Similarly, bioactive compounds: Kaempferol [phosphatidylinositol -3- kinase (PI3K)/protein kinase B (Akt) pathway], Quercetin (controlling the release of 17β-estradiol etc.), Myricetin (PI3K/Akt and MAPK signalling pathway), Galngin (inhibition of angiogenesis via decreasing the VEGF and p-Akt) and Resveratrol (regulation of Foxo3a and SIRT1 genes etc.) shows its effects by targeting different molecules and/or pathways at the ovarian microenvironment. However, Genistein (binding to estrogen receptors: ESRα and ESRβ etc.) and Diadzein (disrupting the endocrines etc.) emphatically interfere with the ovarian functions. Besides this, molecular effects exerted by these phyto-bioactive compounds on the in vivo and/or in vitro ovarian culture systems entirely depend on their dosage: Kaempferol @10 μM increased the primordial follicle activation, Quercetin @4 µM improved the quality of oocytes whereas @8 µM reduced the quality), Resveratrol @ 2 µM increased the blastocyst formation, Myricetin @ 100 mg/kg/day feeding in rats induced estrogenic activity, Genistein, feeding in female mice @ 500 and 1000ppm increased the gestation time and Diazdein causes the inhibition of 3-hydroxysteroid dehydrogenase at 40 µM doses. The assessment was done via the systemic collection of literature from sources such as newspapers, conference papers, journals, theory and dissertation articles, electronic databases, manuals, encyclopedia and annual reviews, as well as e-books and reporting. As a result, the preceding discussion focuses on the key phyto-bioactive compounds and their molecular targets in female fertility. This will aid in the successful and secure application of plant bioactive compounds in the field of female reproductive health.
