Certain types of muscle cells are activated by calcium ions. After activation, the cells expend energy putting the calcium ions back outside the cell. After death, the membranes become more permeable to calcium and the cells don't expend as much energy to push the ions out, so the muscles contract. This does lead to rigor mortis and can lead to ejaculation. It's real. It happens.
A few hours after a person or animal dies, the joints of the body stiffen and become locked in place. This stiffening is called rigor mortis. Depending on temperature and other conditions, rigor mortis lasts approximately 72 hours. The phenomenon is caused by the skeletal muscles partially contracting. The muscles are unable to relax, so the joints become fixed in place. More specifically, what happens is that the membranes of muscle cells become more permeable to calcium ions. Living muscle cells expend energy to transport calcium ions to the outside of the cells. The calcium ions that flow into the muscle cells promote the cross-bridge attachment between actin and myosin, two types of fibers that work together in muscle contraction.
