When does prolactin levels return to pre-pregnancy status in non-breast-feeding women?

• A. 1-2 weeks postpartum
• B. 4-6 weeks postpartum
• C. 2-3 months postpartum
• D. 6-12 weeks postpartum

Answer: (A)

Prolactin levels return to the pre-pregnancy baseline quickly in women who do not breastfeed because, after delivery, there is no nipple stimulation to maintain high prolactin, and the pituitary rapidly returns to baseline. This normalization typically happens within about one to two weeks postpartum. If breastfeeding occurs, nipple stimulation keeps prolactin elevated for as long as lactation continues, which is why the other timeframes would apply to lactating women rather than non-lactating ones.
