Objective To retrospectively compare the effectiveness and safety of 1-year administration of transdermal oestradiol (TE) with cyproterone acetate (CPA) or leuprolide acetate (Leu) in transwomen. Design, patients and measurements Forty transwomen received 50 mg of CPA daily orally (n = 20; CPA+E group) or Leu at a dose of 3.75 mg i.m. monthly (n = 20; Leu+E group) in combination with TE at a dose of 1 or 2 mg daily for 1 year. Reproductive hormones, biochemical parameters, body composition and bone mineral density were assessed. Results LH, FSH and total testosterone levels were significantly decreased by month three of hormone administration in both groups and continued to decrease until month 12; the decrease in LH levels in the first 12 months was significantly faster in the Leu+E group. Prolactin was significantly increased at month 12 in the CPA+E group only. Bone metabolism parameters and bone mineral density as detected at DEXA did not significantly change in either group, apart from a statistically significant increase in parathyroid hormone after 52 weeks of Leu administration. Total cholesterol and HDL-cholesterol were significantly increased in the Leu+E group and reduced in the CPA+E group. No major adverse effects were registered in either group. Psychological well-being parameters did not differ between the two groups. Conclusions Preliminary results from this retrospective observational pilot study suggest that CPA and Leu in combination with TE are equally effective in the suppression of gonadotrophins and testosterone levels over 1 year. Whether the different effects on HDL-cholesterol may lead to long-term different cardiovascular safety profiles remains to be defined.

Abstract

Objective To retrospectively compare the effectiveness and safety of 1-year administration of transdermal oestradiol (TE) with cyproterone acetate (CPA) or leuprolide acetate (Leu) in transwomen. Design, patients and measurements Forty transwomen received 50 mg of CPA daily orally (n = 20; CPA+E group) or Leu at a dose of 3.75 mg i.m. monthly (n = 20; Leu+E group) in combination with TE at a dose of 1 or 2 mg daily for 1 year. Reproductive hormones, biochemical parameters, body composition and bone mineral density were assessed. Results LH, FSH and total testosterone levels were significantly decreased by month three of hormone administration in both groups and continued to decrease until month 12; the decrease in LH levels in the first 12 months was significantly faster in the Leu+E group. Prolactin was significantly increased at month 12 in the CPA+E group only. Bone metabolism parameters and bone mineral density as detected at DEXA did not significantly change in either group, apart from a statistically significant increase in parathyroid hormone after 52 weeks of Leu administration. Total cholesterol and HDL-cholesterol were significantly increased in the Leu+E group and reduced in the CPA+E group. No major adverse effects were registered in either group. Psychological well-being parameters did not differ between the two groups. Conclusions Preliminary results from this retrospective observational pilot study suggest that CPA and Leu in combination with TE are equally effective in the suppression of gonadotrophins and testosterone levels over 1 year. Whether the different effects on HDL-cholesterol may lead to long-term different cardiovascular safety profiles remains to be defined.
