Seventy to eighty percent of women with PCOS do not ovulate.
"because you know 70 to 80% of PCOS patients don't ovulate—" (said at 0:29:45)
The speaker inverted the relationship. Published epidemiological and clinical literature establishes that PCOS accounts for approximately 70% to 80% (or up to 90%) of all cases of anovulatory infertility, rather than 70% to 80% of PCOS patients being entirely non-ovulatory. While ovulatory dysfunction (oligo- or anovulation) is a major diagnostic feature of PCOS, many women with PCOS ovulate intermittently or have ovulatory phenotypes.
