Answer:
The answer is Oxitocin.
Explanation:
The main hormone responsible for uterine contractions during childbirth is OXITOCINE. This hormone is secreted by the pituitary who, in addition to contributing to uterine contractions, also helps in the production of breast milk. Its pharmacological use either IM or IV helps to induce labor, increase the forces of contractions during labor and avoid postpartum hemorrhages.
