Two hormone release by posterior Pituitary gland

 For the female reproductive system, the posterior pituitary gland does not produce hormones itself — it stores and releases hormones that are made by the hypothalamus.


The two hormones released by the posterior pituitary are:


🧠 Oxytocin


Produced by: Hypothalamus (stored and released by posterior pituitary)

Function in females:

Stimulates uterine contractions during labor and childbirth.

Triggers milk ejection (let-down reflex) during breastfeeding.

Plays a role in emotional bonding between mother and baby.

πŸ’§ Antidiuretic Hormone (ADH) (also called vasopressin)

Produced by: Hypothalamus (stored and released by posterior pituitary)

Function:

Controls water balance in the body by acting on the kidneys.

 directly involved in reproduction but important for fluid regulation.
