An Economic Evaluation of Conception Strategies for Heterosexual Serodiscordant Couples with HIV-positive Male Partners

An economic evaluation of the three interventions to conceive without the sexual transmission of HIV between heterosexual, HIV-discordant couples with positive male partners can inform policy decisions to subsidize pregnancy planning in this setting, as there is currently no coverage as such in Ontario. A decision tree and Markov model were designed to determine the short and long-term outcomes of unprotected intercourse restricted to timed ovulation (UIRTO), sperm washing with intrauterine insemination (SWIUI), and unprotected intercourse restricted to timed ovulation with pre-exposure prophylaxis (UIRTO-PrEP). In the short-term, UIRTO was the most cost-effective strategy. In the long-term, cases of negligible HIV transmission risk determined UIRTO-PrEP as the preferred option, while SWIUI was the choice method when this risk was high. There remains a viable risk of HIV transmission between discordant couples during attempts to conceive that require the concurrent and subsidized use of UIRTO-PrEP or SWIUI to protect against HIV infection.
