Sperm are the male reproductive cells. Most animals and plants use sperm to reproduce. They have different ways of making and releasing the sperm. In all cases the sperm meets with the egg of the female and grow into a new organism.
What is 'Gross Domestic Product - GDP' Gross domestic product (GDP) is the monetary value of all the finished goods and services produced within a country's borders in a specific time period. Though GDP is usually calculated on an annual basis, it can be calculated on a quarterly basis as well (in the United States, for example, the government releases an annualized GDP estimate for each quarter and also for an entire year).
Real GDP measures the final output of all goods and services produced in the United States in the prior quarter. It does not measure sales. For example, the BEA counts a new car when it's shipped to the dealer. The BEA records it as an addition to inventory, which increases GDP.
