This may constitute a mechanism for the reduction of breast cancer risk as well as risk for other estrogen-related cancers. Urinary estrogen metabolites and breast cancer: differential pattern of risk found with pre-versus post-treatment collection. The analyses of 4-OHE and the so-called carcinogenic ratio provided somewhat interesting results.
Her invoices for these analyses were paid by Fem Med.

After about five days, estrogen levels rise and the menstrual cycle enters the proliferative phase. Testosteronethe hormone responsible for the secondary sexual characteristics that develop in the male during adolescence, stimulates spermatogenesis.
