Read Pregnancy Hormones from Implantation to Milk
Connect pregnancy maintenance, birth and early milk to their hormonal signals.
Living-system questions are solved by matching a structure or organism to its function, process and stated condition.
Maintain the uterine environment
Progesterone supports the endometrium during pregnancy. The placenta also produces hormones that coordinate maternal and foetal physiology.
Trigger parturition
Signals from the fully developed foetus and placenta contribute to the foetal ejection reflex. Oxytocin released from the maternal posterior pituitary strengthens uterine contractions in a positive-feedback loop.
Understand early milk
Colostrum is the early yellowish secretion rich in proteins and maternal antibodies, including IgA. Prolactin supports milk production; colostrum provides passive immune protection to the newborn.
