Egg meets sperm (article) | Embryology | Khan Academy

If you are on a fertility journey to start or expand your family, you know how special it is when conception takes place. Did you know…. When Sparks Fly So what happens when the lucky sperm finally gets to meet the egg? The magic of conception can happen any time in the week after sexual intercourse has taken place. Research has shown that visible zinc sparks are released along with calcium levels at the time of fertilization. As she grows and ages, the eggs start to die and a mature egg is set free from the ovaries approximately every 28 days.

The cytoplasm of the sperm contains NOS, which is activated along with the acrosome reaction by contact with egg jelly yellow ; above, the NOS turns green when activated and produces NO light green spray. Upon fusion with the egg, NOS is released into the egg, whereby the NO produced activates calcium release red spray. Calcium activates NOS already present in the egg, releasing more NO, which releases more calcium, and so on. In recent years, researchers have learned that nitric oxide NO is much more than an air pollutant.
