Behavioral response to vasectomy.

This article reviews the literature concerning the behavioral and psychological response of men and their wives to the vasectomy operation when used as a contraceptive technique. The data suggest that two primary changes may frequently be observed postoperatively. Individuals who have experienced anxiety in conjunction with intercourse because of a fear of contraceptive failure or pregnancy tend to report a decline in anxiety and a disinhibition of sexual arousal postoperatively. Also, test results suggest that behavoir patterns within the marital dyad are altered in some cases when the men adopt stereotyped masculine behavior, presumably to deny any suggestion that they are less masculine because of the operation. Ramifications of these findings as well as numerous other speculations, are considered, along with the suggestion that prescreening and postvasectomy counseling may help reduce negative response to the operation.

Quantitation of retention of endosseous dental blade implants in dogs.

This research was initiated in order to study the extraction forces associated with solid, single-vented and multi-vented blade dental implants placed in mandibles of dog for 2 months. An extraction device was used to measure the extraction forces on five of the implants and a histological study was carried out around the sixth multi-vented implant. The main finding was that the extraction forces for the multi-vented blade implants were 6 to 12 times those of the single-vented and solid blades. Other findings in this study were: none of the implants exhibited mobility; sulci ranged from 2 to 3 mm at the implant neck; bone covered the implant shoulder. There was gross and histologic evidence of bone growth in the vents of the multi-vented blade; close adaptation of the bone, connective tissue capsule and implant; and no gross, histologic, clinical or radiographic evidence of bone pathology.
