Sterilization in men, or vasectomy, is an irreversible form of contraception where the vasa deferentia -- the sperm-carrying tubes from testicles to the penis are blocked.
Tying and cutting of a small piece of vas deferens is by far the most widespread method of the procedure in many progressive countries. Alongside with this approach, in the United States of America and other high-developed countries, metal clips or burning are often used more regularly. Current male sterilization information shows that vasectomy on average has been linked with around one pregnancy per a hundred users during the course of the first year, even if its effectiveness can rely on the used surgical procedure type.

Essential Male Sterilization Information: Male Sterilization Reversal
In order to make an allowance for reproduction (by means of artificial insemination) following vasectomy, some men decide on cryostorage of sperm prior to sterilization. Nevertheless, the long-standing viability of spermatozoa in cryostorage is uncertain.
Even though there is a procedure to reverse vasectomy by means of vasovasostomy (a microsurgery form), it does not have a desired effect in many cases, hence men considering vasectomy should not think of it as reversible, although it may be more or less reversible, dependent on of the type of surgery procedure used.
A range of reversal male contraceptives is being studied but not available up till now. These may include the intra vas device and male oral contraceptives. There has been at least one acknowledged case of a vasectomy reversal on a dog, which afterward fathered puppies.
Well that's great information if your dog lover, but what if you want more children?
