What is STRAW+10?

Scroll this

STRAW+10 is the proposed nomenclature and a staging system for ovarian aging including menstrual and qualitative hormonal criteria to define each stage. In other words, a tool for diagnosing each stage of perimenopause and beyond.

The STRAW criteria are widely considered the gold standard for characterizing reproductive aging through menopause, just as the Marshall-Tanner Stages characterize pubertal maturation5.

The contents on this website often relate back to specific stages of the STRAW+10 nomenclature as one of my objectives with this website is to make this diagnostic tool more widely known to the public as well as primary health care providers. You will see that the various stages appear as categories and tags throughout the contents on this website.

Research conducted over the past ten years has advanced knowledge of the critical changes in hypothalamic-pituitary and ovarian function that occur before and after the final menstrual period. These advances were the topic of a follow-up workshop STRAW+10: Addressing the Unfinished Agenda of Staging Reproductive Aging (STRAW+10). STRAW+10, held in Washington DC on September 20 and 21, 2011, reviewed these scientific advances and updated the STRAW model.
