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 widely known and accepted condition with ongoing study being pursued by healthcare professionals. D-MER has been mentioned in several breastfeeding texts and self-help books since 2010 and awareness of this anomaly is steadily growing across the internet and within the medical community. References to D-MER can be found in the news , on blogs, Twitter and even Reddit. However, as of March 2014, there has been no scientific research studies involving mothers who experience D-MER to support the hypothesis that it is caused by the drop in dopamine just prior to the milk ejection reflex. There is a strong argument
