Thesis (MSc)--University of Stellenbosch, 2000. / ENGLISH ABSTRACT: Many men are of the opinion that a vasectomy will have a detrimental effect on their sexual satisfaction, which is why this convenient method of contraception is often ignored. The purpose of this study was to determine whether a vasectomy had any effect on important aspects of a marriage, such as sexual satisfaction, marital satisfaction, communication and frequency of sexual intercourse. An experimental group and two control groups were used and data were collected by means of a biographical questionnaire and two questionnaires which were applied before and five months after the vasectomy. Results indicated no significant difference between the before and after measurements regarding sexual satisfaction, marital satisfaction, communication and frequency of sexual intercourse. It was also revealed that although strong correlations were found between marital satisfaction, communication and sexual satisfaction, a weak correlation was found between frequency of sexual intercourse and the other measured variables. / AFRIKAANSE OPSOMMING: Verskeiemansmeendat 'n vasektomie hul seksuele satisfaksie nadelig sal beïnvloed en daarom word hierdie gerieflike geboortebeperkingsmetode dikwels oor die hoof gesien.
