Patterns of discretion and disclosure of fertility-related information among Israeli recipients of donor insemination (DI) are explored. Based on questionnaires completed by recipients in four sperm banks, we studied differences between married women and men. We found that most Israeli recipients conceal the treatment from their friends and relatives. Women and men, however, differ in their disclosure patterns: women are somewhat more open about the general fertility problem, but conceal the male factor; men are more discreet. However, men who disclose the fertility problem also tell about their own impairment. DI appears to be the most secretive issue in this context. Recipients who confided in anyone about their problem restricted it mostly to family relatives. The results are interpreted in terms of Israeli pronatalism, traditional concepts of the natural family, as well as elements of macho culture. Public education is highly recommended in order to open and “normalize” DI in Israel.
