research Is dehydroepiandrosterone a hormone?
Dehydroepiandrosterone (DHEA) is a prohormone important for producing sex steroids and has potential health benefits.
research Intratumoral De Novo Steroid Synthesis Activates Androgen Receptor in Castration-Resistant Prostate Cancer and Is Upregulated by Treatment with CYP17A1 Inhibitors
Prostate cancer cells can make their own androgens to activate the androgen receptor, and treatments like abiraterone may increase this ability, suggesting new therapies should target the entire steroid-making pathway.
research Relative Prevalence of Different Androgen Excess Disorders in 950 Women Referred because of Clinical Hyperandrogenism
Most women referred for excess male hormone symptoms had polycystic ovary syndrome (PCOS), with other conditions being less common.
