Breast cancer incidence in postmenopausal women using testosterone in addition to usual hormone therapy

This observational study examined the incidence of breast cancer in postmenopausal women using conventional hormone therapy (HT) with the addition of testosterone implants. The findings suggested that adding testosterone to standard HT was associated with a lower incidence of breast cancer compared to HT alone, indicating a potential protective effect.

Absorption of Oral Progesterone is Influenced by Vehicle and Particle Size

This clinical trial examined how oral progesterone absorption is influenced by formulation, specifically particle size and vehicle type. Seven subjects received a 200 mg dose of progesterone in different formulations: plain milled, micronized, plain milled in oil, micronized in oil, and micronized in enteric-coated capsules. Serum progesterone levels were measured
