What describes autocrine control of lactogenesis stage III?

• A. Milk production decreases with less suckling
• B. Milk production increases with more milk removed
• C. Oxytocin levels drop
• D. Prolactin receptors become more sensitive

Answer: (B)

The description of autocrine control of lactogenesis stage III primarily revolves around the responsiveness of milk production to the removal of milk from the breast. During this stage, a key mechanism involves the autocrine regulation where the presence of milk in the mammary gland regulates further milk production. When milk is effectively removed through suckling or pumping, it signals the body to stimulate more milk production due to the decrease in intramammary pressure and the feedback mechanism involved. Thus, as more milk is removed, the production is encouraged and effectively increased, exemplifying the autocrine control's role in ensuring a sufficient supply of breast milk based on the demand or usage. Additionally, autocrine control does not imply a decrease in production with less suckling nor an increase in sensitivity of prolactin receptors. Moreover, while oxytocin is involved in the milk ejection reflex, its levels decreasing is not the focal aspect of autocrine control during this stage. The primary feature is the body's ability to adjust milk synthesis in direct response to the removal of milk, which encapsulates the essence of autocrine control in this process.
