Negative effects of oophorectomy (castration, or removal of the ovaries) on a woman's sexual functioning, mood and body image have been documented in previous studies, but these studies did not measure vaginal blood flow and often did not include a non-surgical control group. Five groups of women aged 35 to 55 years were studied, a non-surgical control group (CTL), a hysterectomy-only group (TAH, at least one ovary intact) and three oophorectomy groups: an untreated group (BSO), women on estrogen-replacement therapy (ERT) and women on androgen-estrogen replacement therapy (HRT). The interview/questionnaire assessed mood, body image and sexual functioning (sexual desire, arousal, orgasm, interpersonal sexual activities). In a second session completed by 58 and 129 subjects (45%), a vaginal photoplethysmograph measured vaginal blood flow in response to an erotic stimulus while subjects concurrently monitored subjective arousal. Overall, the BSO and ERT groups had significantly lower self-reported desire and arousal. Body image as measured by a new scale, 'body comfort', was significantly poorer in the BSO group. The hysterectomy groups had more sexual problems than the control group. Further, about a third of the CTL group reported positive changes in body image and sexuality in the previous 5 years. This effect was attenuated in the TAH, HRT and ERT groups and almost absent in the BSO group. No significant group differences were obtained however, on mood, or vaginal blood flow and subjective arousal to an erotic stimulus. Vaginal blood flow and subjective arousal were significantly correlated. The possibility that these findings may be due to differential levels of testosterone in the various groups is discussed.
