This operation of vasectomy, sometimes known as "Rentoul's operation," consists, in the male, in the removal of a small portion of each sperm duct; the individual is thus rendered sterile in a completely effective and permanent way. At the same time there are none of the harmful effects, either physical or mental, such as usually follow the better known forms of sterilization which are in reality asexualization rather than sterilization. Vasectomy is a simple "office" operation occupying only a few minutes and requiring at the most the application of only a local anæsthetic, such as cocaine; and there are no disturbing nor even inconvenient after effects. In the female the corresponding operation of oöphorotomy consists in removing a small portion of each Fallopian tube. In Indiana nearly a thousand persons have already been successfully treated, many upon their own request--a circumstance entirely unforeseen. Similar laws have been passed in Oregon and Connecticut, and are being carefully considered in several other States. In order that the exact nature of such proposals may be better known generally we may give here also the text of the Connecticut law which is somewhat more inclusive and more flexible than that of Indiana. The Connecticut Statute, enacted in August, 1909, is as follows: _An Act_, concerning operations for the Prevention of Procreation.--Be it enacted by the Senate and House of Representatives in General Assembly convened: _Section 1._ The directors of the State prison and the superintendents of State hospitals for the insane at Middletown and Norwich are hereby authorized and directed to appoint for each of said institutions, respectively, two skilled surgeons, who, in conjunction with the physician or surgeon in charge at each of said institutions, shall examine such persons as are reported to them by the warden, superintendent, or the physician or surgeon in charge, to be persons by whom procreation would be inadvisable.
