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 and describe the phenomenon to lactation professionals in 2007. It was chosen due to the emotional reaction (dysphoria) to milk let-down (milk ejection reflex). The "milk ejection reflex" is abbreviated among lactation professionals and referred to as the M-E-R. This means that D-MER is not said DEE-MERE, but rather D.M.E.R, all the letters names said individually. In 2008 a team of lactation consultants, headed up by Diane Wiessinger, MS, IBCLC, LLLL worked together and consulted with other medical professionals to do a preliminary investigation to better understand D-MER. After the first published case study of D-MER, it became a more
