Why does breast feeding suspend pregnancy?

  • Breast-feeding can prevent pregnancy. 
  • Breast-feeding can delay the ovulation after giving birth. The hypothalamus secretes the Gonadotropin Releasing Hormone which is reponsible for menstruation sequence. 
  • The GnRH repressed by the prolactin hormone, which encourages the production of breast milk. 
  • Without the GnRH release, the menstrual cycle won't begin a new in the event of a pregnancy. 
  • As long as prolactin levels are high, GnRH generally won't be released. So, there will be a delay in ovulation that automatically prevent pregnancy. But, it is not a fully reliable process of contraception. It can vary in individuals.
