What is the medical term meaning suture of ductus deferens?

The correct medical term for suture of ductus deferens is "vasovasostomy." This procedure involves the surgical reconnection of the vas deferens, which is the tube that carries sperm from the testicles to the penis. Vasovasostomy is typically performed to reverse a previous vasectomy, which is a procedure that cuts and seals the vas deferens to prevent sperm from being released during ejaculation.
