In breastfeeding, the act of an infant suckling the nipple stimulates the production of prolactin, which fills the breast with milk via a process called lactogenesis, in preparation for the next feed. Prolactin levels are controlled by other hormones called prolactin inhibiting factors (PIFs), such as dopamine. Summary: Mean 24‐hour integrated concentrations of serum prolactin (PRL) in 8 breast‐feeding mothers (62 ± 10.4 μg/1) was significantly higher than in 4 control subjects (14.8 ± 3.3 μg/1).
