Staudt MD, Truitt WA, McKenna KE, de Oliveira CV, Lehman MN, Coolen LM (2012) A pivotal role of lumbar spinothalamic cells in the regulation of ejaculation via intraspinal connections. J Sex Med 9(9):2256-2265. doi: 10.1111/j.1743-6109.2011.02574.x
Summary: The authors examined the hypothesis that specific lumbar spinothalamic (LSt) cells control ejaculation through intraspinal connections. Rats received six bilateral injections of SSP-SAP (Cat. #IT-11) into the spinal cord, 48 ng in total. Saporin (Cat. #PR-01) was used as a control. It was found that while erectile function and emission were not affected, the usual rhythmic contractions of the bulbocaveronosus muscle during ejaculation were prevented.
