We are many years, if not many decades, away from being able to reconnect a severed spinal cord.
Reconnecting even the relatively small number of nerves for re-attaching such as a severed arm is still a long way from perfect; the spinal cord contains many millions...

Number of neurons in human spinal cord = 1 billion (from Kalat, J.W., Biological Psychology, 6th Edition, 1998, page 24)
[If it could work, the result would be a man's mind controlling a woman's body].
