Human fertilization - Wikiped

Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development.Scientists discovered the dynamics of human fertilization in the nineteenth century.. The process of fertilization involves a sperm fusing with an ovum.

How does the fertilized egg "know" when and where to .

All of the cells in a multi-cellular organism's body have the exact same DNA (for the most part), and yet those cells have very different morphologies. This is possible because cells turn different genes on or off in response to internal or extern...

Calcium at fertilization and in early developme

B. How a sperm activates an egg – a survey of experimental approaches. Fertilization calcium waves are autonomous and a property of eggs and oocytes: they can be triggered by microinjection of calcium or InsP 3 or, indeed, by a needle prick. The answer to how a sperm activates an egg is a simple one in outline: interaction of the sperm with the egg triggers a signal transduction pathway that ...

Failure of Male Pronucleus Formation Is the Major Cause of .

Our results in the pig imply that oocyte-activating factors in the sperm are still functional after freeze-thawing. However, these factors were not involved in the transformation of sperm head to male pronucleus. The failure of sperm head decondensation, therefore, may be attributed to the inadequacy of the oocytes.

Dynamics of Male and Female Chromatin during Karyogamy in Rice Zygotes | Plant Physiolo

In angiosperms, the conversion of an egg cell into a zygote involves two sequential gametic processes: plasmogamy, the fusion of the plasma membranes of male and female gametes, and karyogamy, the fusion of the gametic nuclei. In this study, the nuclei and ...
