Conflict Statement Dr. Gleicher is listed as co-inventor on a number of pending patent applications claiming diagnostic and therapeutic benefits from determination of CGG repeat numbers and ovarian FMR1 genotypes and sub-genotypes. Dr. Gleicher is co-inventor of awarded U.S. patents, claiming therapeutic benefits for supplementation of DHEA in women with diminished ovarian reserve, a topic discussed in this talk. Other patent applications in regards to DHEA and other fertility-related claims, with no relationship to this talk, are pending. Dr. Gleicher receives royalties from, and owns shares in Fertility Neutraceuticals, LLC, a distributor of a DHEA product. Dr. Gleicher is co-inventor of three pending patent applications claiming potential therapeutic benefit for anti-müllerian hormone (AMH) in infertile women. Dr. Gleicher owns shares in OvaNova Laboratories, LLC.
Outline Definition of PCOS PCOS phenotypes PCOS phenotypes change with age Sources of androgens How androgens control ovaries The hypo-androgenic PCOS
Definition of PCOS Amalgam of clinical conditions Various classifications proposed None universally accepted 2003 Rotterdam Criteria Oligo-/Amenorrhea Hyperandrogenism Chemial and clinical Ovarian PCO phenotype
Varying PCOS Definitions NIH 1990 Hyperandrogenism andor hyperandrogenemia Oligoovulation Exclusion of other causes Rotterdam 2003 Exclusion of other causes 2/3 Oligoovulation Hyperandrogenism Polycystic ovaries
Rotterdam 2003 Expanded NIH 1990 by 2 New Phenotypes Ovulatory women with PCO and hyperandrogenism Oligoanovulatory with PCO but without hyperandrogenism Phenotype-D!
Other Phenotypical Descriptions of PCOS Classical: Obese/high AMH Hirsute/anovuulatory/hyperandrogenic Metabolic syndrome Lean: Skinny /high AMH Often regular menses Hyper-through hypo-androgenic, depending on age Treatment resistant Hypo-androgenic PCOS

Testosterone Response
Hypoandrogenic PCOS Clinical diagnosis High AMH for age in reference to FSH Low T Low DHEAS High SHBG Autoimmunity Low cortisol Good response to DHEA mostly to thyroid
Endocrinol 2017; In press
Once recognized, hypoandrogenic PCOS is surprisingly common at all ages in tertiary fertility centers
If diagnosed and properly androgen-supplemented, patients have excellent pregnancy and live birth chances
