Comment: The quality of evidence is downgraded by study quality ( unclear allocation concealment and unclear blinding of outcome assessment).
A Cochrane review included 27 studies with a total of 16 393 subjects. For estrogens alone vs control, in symptomatic or early postmenopausal (within five years of amenorrhoea ) women there was a small to moderate benefit in sexual function for the hormone therapy (HT) group (standardized mean difference (SMD) 0.38, 95% CI 0.23 to 0.54, P < 0.00001; 3 trials, n=699, I² = 55%, high-quality evidence). In unselected postmenopausal women, there was no clear benefit (SMD 0.16, 95% CI -0.02 to 0.34, P = 0.08; 2 trials, n=478, I² = 44%, low-quality evidence). For estrogens combined with progestogens vs control, in symptomatic or early postmenopausal a small to moderate benefit for sexual function in the HT group was found (SMD 0.42, 95% CI 0.19 to 0.64, P = 0.0003; 1 trial, n=335, moderate-quality evidence). In unselected postmenopausal women, no clear benefit was shown (SMD 0.09, 95% CI -0.02 to 0.20, P = 0.10; 3 trials, n=1314, I² = 0%, moderate-quality evidence).
For tibolone vs control, in symptomatic or early postmenopausal women no clear benefit was found (SMD 0.13, 95% CI 0.00 to 0.26, P = 0.05; 1 trial, n=883, low-quality evidence); as well as in unselected postmenopausal women (SMD 0.38, 95% CI 0.04 to 0.71, P = 0.03; 2 trials, n=142, I² = 0%, low-quality evidence). In the combined analysis, the 95% CI was compatible with no effect to a small benefit (SMD 0.17, 95% CI 0.04 to 0.29, P = 0.008, 3 studies, 1025 women, I² = 20%).
For selective estrogen receptor modulators (SERMs) vs control, in symptomatic or early postmenopausal no clear benefit was found (SMD 0.23, 95% CI -0.04 to 0.50, P = 0.09, 1 trial, n=215, low-quality evidence) as well as in unselected postmenopausal women (SMD 0.04, 95% CI -0.20 to 0.29, P = 0.72, 1 trial, n=283, low-quality evidence). In the combined analysis, the 95% CI was compatible with no effect to a small benefit (SMD 0.13, 95% CI -0.05 to 0.31, P = 0.16, 2 studies, 498 women, I² = 2%).
