Prolactin's primary functions are to stimulate milk production and promote mammary gland development.
Prolactin: A Key Hormone
Prolactin, a hormone produced by the pituitary gland, plays a vital role in reproduction and lactation. While it has hundreds of physiological functions, its two main responsibilities are directly related to mammary gland development and milk production, primarily in females.
Primary Functions of Prolactin
Prolactin’s influence is crucial for preparing the body for breastfeeding and maintaining milk supply after childbirth. The following table summarizes its key functions:
| Function | Description |
|---|---|
| Milk Production | Prolactin stimulates the mammary glands to produce milk. |
| Mammary Gland Development | Prolactin promotes the growth and development of the mammary glands within breast tissues, specifically the mammary alveoli where milk production occurs. |
Prolactin promotes the growth of mammary alveoli, which are the components of the mammary gland, where the actual production of milk occurs.
Examples of Prolactin's Action
- During Pregnancy: Prolactin levels increase, preparing the mammary glands for milk production after delivery.
- Postpartum: When a baby suckles, prolactin levels surge, triggering milk release.
- In Males: Prolactin also plays a role in male reproductive function, although its exact functions are still being researched.
Maintaining Healthy Prolactin Levels
Maintaining appropriate prolactin levels is important for both men and women. Imbalances can lead to various reproductive and metabolic issues.
