Breast Cancer Incidence in Postmenopausal Women Using Testosterone in Addition to Usual Hormone Therapy • Objective: To determine if testosterone protects women from breast cancer when added to standard hormone therapy • Design: Retrospective, observational trial of 508 postmenopausal women receiving testosterone therapy (average age 56.4; mean follow-up 5.8 years) • Outcomes: Breast cancer incidence with testosterone compared to nonusers and standard hormone therapy users from the literature From: Dimitrakakis, Jones, Liu and Bondy.

Breast Cancer Incidence in Postmenopausal Women Using Testosterone in Addition to Usual Hormone Therapy • Results: expressed as rate/100,000 women-years • On testosterone: 238 • On testosterone, estrogen/progestin: 293 • On estrogen/progestin (from WHI): 380 • On estrogen/progestin (from Million Women Study): 521 • Never users (from Million Women Study): 283 • Conclusions: “…the addition of testosterone to conventional hormone therapy for postmenopausal women does not increase and may indeed reduce the hormone therapy-associated breast cancer risk-thereby returning the incidence to the normal rates observed in the general, untreated population” From: Dimitrakakis, Jones, Liu and Bondy. Menopause: 11: 531-535, 2004
Summary and Conclusions • There is a serious need for safe and effective therapies for all aspects of sexual dysfunction in women • Low sexual desire is a very common complaint of postmenopausal women affecting more than 20% of women over age 40 • While hormone therapy appears to increase the risk of breast cancer, the addition of testosterone does not appear to increase this risk.
