Has Prasterone been used to help manage sexual dysfunction side effects from breast cancer treatment?
Sexual side effects are really common with the treatment combination being used here. Letrozole and Zoladex together dramatically lower estrogen, which can cause:
- Vaginal dryness
- Painful sex

- Vaginal atrophy Prasterone (Intrarosa) is a vaginal insert that converts to estrogen and testosterone locally. Because it acts locally rather than raising systemic estrogen levels, some oncologists consider it for ER/PR-positive patients — but this is a genuinely complex area, and opinions among breast cancer specialists vary.
Given the ER/PR-positive status combined with Letrozole (which works specifically by suppressing estrogen), this is absolutely a conversation to have directly with the oncology team before trying Prasterone. They'll need to weigh the risks carefully for this specific situation. In the meantime, some options that are generally considered safer to explore include:
- Vaginal moisturizers like Replens (used regularly, not just before sex)
- Water-based lubricants during intimacy
- Asking about pelvic floor physical therapy
A MyBCTeam member shared that even Replens felt uncomfortable, describing it as painful — so it's worth knowing results vary, and persistence in finding what works matters.
Advocating for quality of life is completely valid — as one MyBCTeam member put it, "your happiness and pleasure matter!"
