[Q]: How common is vasectomy?\nVasectomy is used as a means of contraception in many parts of the world. A total of about 50 million men have had a vasectomy--a number that corresponds to roughly 5 percent of all married couples of reproductive age. In comparison, about 15 percent of couples rely on female sterilization for birth control.\n\nApproximately half a million vasectomies are performed in the United States each year. About one out of six men over age 35 has been vasectomized. The prevalence of men undergoing the procedure increases with higher levels of education and income. Among married couples in the United States, only female sterilization and oral contraception are relied upon more often for family planning.\n\nHow is vasectomy done?\nIn the conventional approach, a physician makes one or two small incisions, or cuts, in the skin of the scrotum, which has been numbed with a local anesthetic. The vas is cut, and a small piece may be removed. Next, the doctor ties the cut ends and sews up the scrotal incision. The entire procedure is then repeated on the other side.\n\nRelated Links on MedicineNet.com \n\nPage 2 of this Article \nRelated Medical Procedures and Tests\nThe Doctor's Response\nInformation on this web site is provided for informational purposes only and is not a substitute for professional medical advice.

Vasectomy is a popular method of birth control: in 1983, figures showed that approximately 10 million men had been sterilized in the U.S. since 1969. Excision of the vas deferens is a minor surgical procedure that can be performed in a physician's office in less than half an hour. A small incision is made on one side of the scrotum (the external sac housing the testes) and the vas deferens is located, cut, and the ends tied off. The incision is closed and the procedure is repeated on the other side. After surgery, it is necessary to wait until a negative sperm count is obtained before discarding other means of contraception, because viable sperm cells are retained in the seminal vesicles (the pair of storage pouches where sperm is mixed with other components of semen) and along the various sperm ducts. In addition it is usually advised that the patient be reexamined after a year, because the severed ends of the vas deferens occasionally reknit. Sterility resulting from vasectomy is considered to be permanent, and attempts at surgically reversing vasectomy, called vasovasotomy, have had limited success. In India, where the government is trying to stem the tide of overpopulation, money is paid to men who submit to voluntary vasectomy. Efforts to overcome the irreversibility of vasectomy have also led to experimentation with the implantation of faucetlike devices that can be made to open or close the sperm duct in a simple operation. Such devices have functioned successfully in animals but are still considered experimental in humans because of their unproved reversibility, high cost, and the degree of surgical skill needed to implant them. Another option suggested to those undergoing vasectomy is to preserve their fertility by depositing semen in sperm banks. Such semen samples are frozen in liquid nitrogen below −300°F (−185°F) and are considered to be viable for an indefinite period. However, there is considerable debate over the scientif

[Q]: Sure. See http://www.oum.ox.ac.uk/dodo.htm - - they say they have the "most complete" collection of authentic biological (skeletal) samples from a (once) living dodo.
