Physiology of Birth

Oxytocin is produced at different points in labour.  The number of processes and factors are important for the physiology of birth to occur at specific key points and if this is interfered with then the physiology of birth does not flow smoothly.  

These are the key points when Oxytocin is produced.

  • The pressure of the baby on the cervix
  • Distension of the vagina
  • Fanning out of the pelvic floor muscles and the perineum
  • Stretching of the perineum as the baby’s head is crowning (being born)
  • Clitoral stimulation
  • Nipple stimulation
  • Skin to skin contact with the baby
