Birth control is the spacing or preventing of pregnancies.

2. • Population growth is steadily increasing in a
geometric proportion.
• The population can be controlled either by
decreasing the number of births or increasing
the number of deaths.
• Developing medical sciences and human law
do not permit the increased death-rate.
• Only way to control the growth of population
is reduced the number of births.
• Best way to reduce birth is preventing fusion
of sperms and eggs(fertilization) that refers
the prevention of pregnancies or birth control.

3. • Birth control
is the
spacing or
preventing of
pregnancies.

an egg(ovulation) by the ovaries and
changes the mucous produced by the
cervix, slowing or preventing the
movement of sperm.
