Mammalian fertilization comprises sperm migration through the female reproductive tract, biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct. Recent gene knockout approaches in mice have revealed that many factors previously considered important for fertilization are largely dispensable, or if they are essential, they have an unexpected function. These results indicate that what has been observed in in vitro fertilization (IVF) differs significantly from what occurs during “physiological” fertilization. This Review focuses on the advantages of studying fertilization using gene-manipulated animals and highlights an emerging molecular mechanism of mammalian fertilization.
Answer:
Micronutrients helps in preventing the skin from different types of allergens or pollen which may result in skin rashes or hives. It protects skin againts various pathogens or fungi. It acts as anti oxidants on skin and thus prevents premature ageing. It also protects from harmful UV radiateion which damages DNA.
