What is the Meaning of Bioidentical Progesterone?

Bioidentical Progesterone is a pharmaceutical preparation of the naturally occurring human steroid hormone progesterone, synthesized to be chemically indistinguishable from the endogenous molecule. This specificity is vital for achieving physiological receptor binding without the undesirable side effects sometimes associated with synthetic progestins. We use this to support menstrual cycles, fertility, and menopausal symptom management.

What is the Origin of Bioidentical Progesterone?

The term 'bioidentical' highlights its structural congruence with the progesterone synthesized naturally within the corpus luteum or adrenal glands. This contrasts with older synthetic progestogens that possess differing molecular side chains impacting receptor affinity.

What is the Mechanism of Bioidentical Progesterone?

Bioidentical progesterone functions by binding with high specificity to the intracellular Progesterone Receptor (PR), acting as a ligand-activated transcription factor to regulate target gene expression. This modulation is crucial for preparing the endometrium and exerting negative feedback on the Hypothalamic-Pituitary-Ovarian axis. Its accurate structural match promotes predictable physiological outcomes.
