Objective To investigate the relationship between the first polar body morphology of oocyte and the zygote morphology in pronucleus stage, embryo quality in cleavage stage.
Abstract: Aim:To establish the methods of microfertilization and explore the fertilizing potential of mouse sperm obtained from caput epididymidis and cauda epididymidis.
Traditionally, doctors use gestational age, the number of weeks from fertilization to birth, to determine whether a preemie should receive invasive care.
As the bee moves from flower to flower, the pollen falls off hopefully dusting the female reproductive structure that fertilizes the plant's reproductive organs kick starting the production of seeds and new plants.
So in today's programme, we've been hearing about the important role bees play in pollination-transferring pollen from plant to plant, necessary for the next stage of fertilisation-producing new seeds and fruit inside a plant.
