Abstract
OBJECTIVE: To review published data pertaining to the effects of tibolone on sexual
parameters, mood, and cognitive function in postmenopausal women.

DESIGN: A review of all relevant published, peer-reviewed studies.

RESULTS: Tibolone is a compound that can be selectively metabolized by individual
tissues to its estrogenic, progestogenic, or androgenic metabolites and hence exhibits
tissue-specific hormonal effects. Tibolone also lowers sex hormone binding globulin,
thus increasing free estradiol and testosterone levels. Tibolone alleviates climacteric
vasomotor symptoms and displays a dominant progestogenic effect on the endometrium.
Tibolone normalizes the vaginal karyopyknotic and maturation indexes and alleviates
symptomatic atrophic vaginitis. Women treated with tibolone report significant
reductions in vaginal dryness and dyspareunia, effects that may be secondary to both
estrogenic and androgenic actions. Randomized studies indicate tibolone has positive
effects on mood compared with placebo and alleviates several adverse mood parameters
to a similar extent as conventional hormone replacement therapy. Improved mood is
associated with increased plasma beta-endorphin. With respect to cognition, tibolone
seems to improve semantic memory but does not significantly improve recognition
memory. Tibolone is associated with improvements in sexual function that seem to be
greater than those achieved with standard hormone replacement therapy.
CONCLUSION: Published studies indicate beneficial effects of tibolone on both libido
and mood, which otherwise significantly compromise physical, psychological, and social
well-being. Hence, tibolone provides another option for menopausal women experiencing
loss of libido as part of their symptomatology or who have persistent low libido despite
adequate estrogen/progestin replacement therapy.
