1 study
  1. Oestradiol + progesterone decreases mortality in silico (-615 deaths per 10,000).

    “was associated with 285 fewer cases of ASCVD, 18 more colon cancer cases, 46 more breast cancer cases, 183 fewer hip fractures, and 615 fewer deaths.”

1 study
  1. Oestradiol + progesterone improves cost-effectiveness in silico (-$127,738,990, +33,083 QALYs per 10,000).

    “Micronized progesterone compared with no MHT was $127,738,990 less expensive, resulted in a gain of 33,083 QALYs”

1 study
  1. Oestradiol + progesterone increases FOSB in mouse cells.

    “In vitro co-treatment with estradiol and progesterone increased FOSB and BACE1 levels, supporting the presence of a hormone-responsive regulatory link.”
