Dysphoric milk ejection reflex sense of depression and this feeling can range from mild homesickness or wistfulness to more intense feelings of hopelessness and self-loathing. Similarly, anxiety may range from restlessness to more intense panic and dread. Anger, the least likely of the three, may range from tension and agitation to more intense feelings of hostility and aggression. The mechanism is not clear. In a mother with D-MER, dopamine may fall inappropriately with milk release, causing the negative feelings. Among the hormones involved in milk production and release are oxytocin, prolactin, and dopamine. Oxytocin, released in pulsatile "spikes" from the posterior pituitary in response
Refractory period (sex) each refractory period. Another chemical which is considered to be responsible for the male refractory period is prolactin, which represses dopamine, which is responsible for sexual arousal. Because of this, there is currently an experimental interest in drugs which inhibit prolactin, such as cabergoline (also known as Cabeser, or Dostinex). Anecdotal reports on cabergoline suggest it may be able to eliminate the refractory period altogether, allowing men to experience multiple ejaculatory orgasms in rapid succession. At least one scientific study supports these claims, although cabergoline is a hormone-altering drug and has many potential side effects. It has not been approved
