Moreover, following the birth of the child, prolactin promotes bonding between the father and the newborn. Prolactin levels can also increase during socially stressful situations in humans. This has been seen by administering the Trier Social Stress Test (TSST), and then measuring blood serum prolactin concentrations. The TSST is a widely ...
High levels of progesterone, which are associated with pregnancy, inhibits prolactin and therefore lactation. [30] Prolactin increases during the initial stages of lactation and can be stimulated by estrogen but not progesterone. [30] Research, however, focuses on the role of prolactin for breastfeeding and less on other behaviors. [30]
Levels can rise after exercise, high-protein meals, minor surgical procedures, [49] following epileptic seizures [50] or due to physical or emotional stress.

In these cases, high perceived pressure raises cortisol levels inside the body. [18] [21] The elevated level of the stress hormone affects the secretion of lactogenic hormones in the mother, which delays the onset of lactation. [22] Women who underwent a c-section are more likely to experience DOL compared to women who delivered vaginally.
