Refractory period (sex) autonomic feedback mechanism, rather than through central chemicals like oxytocin, serotonin, and prolactin. Autonomic feedback is already known to regulate other physiologic systems, such as breathing, blood pressure, and gut motility. This theory suggests that after male ejaculation, decreased wall tension in structures such as the seminal vesicles leads to a change in the fine autonomic signals sent from these organs, effectively creating a negative feedback loop. Such a mechanism is similar to decreased gastric and bowel motility once gastric contents have passed through. Once the feedback loop has been created, the refractory period remains until the loop is broken
Dysphoric milk ejection reflex Dysphoric milk ejection reflex Dysphoric milk ejection reflex (D-MER) is an anomaly of the milk release mechanism in lactating women. A lactating woman who has D-MER experiences a brief dysphoria just prior to the milk ejection reflex. The lactating woman who has D-MER experiences a brief period of dysphoria that begins just prior to the milk ejection reflex and continues for not more than several minutes. It may recur with every milk release or only with the initial milk release at each feeding. D-MER always presents as an emotional reaction but may also produce a hollow or churning feeling in
