What is Prolactin?

Prolactin is a hormone produced by the pituitary gland, primarily known for its role in lactation and breast development in women. However, it also plays other important roles in both men and women, influencing reproductive health, metabolism, and immune function. Understanding prolactin levels and their implications is essential for assessing hormonal balance and overall well-being.

High Prolactin Levels

Elevated prolactin levels can indicate various conditions:

• Hyperprolactinemia: Excessively high prolactin levels can result from conditions such as prolactinoma (a benign tumor of the pituitary gland), hypothyroidism, medications, or chronic stress.
• Reproductive Issues: High prolactin levels may disrupt menstrual cycles and fertility in women, and contribute to erectile dysfunction and decreased libido in men.
• Galactorrhea: Spontaneous flow of milk from the breasts unrelated to breastfeeding, which can occur in both women and men with high prolactin levels.

Low Prolactin Symptoms

Low prolactin levels are less common but can occur due to conditions affecting the pituitary gland or hypothalamus. Symptoms may include irregular menstrual cycles in women or difficulties with lactation after childbirth.
