• “New” PCOS Info: 4 Types (AGAIN)

  On March 29, 2023, we released an episode titled, “The 4 PCOS Phenotypes”. That was in 2023! Now, on 29 October 2025, in the journal Nature Medicine, researchers have published, “Data-driven (FOUR) subtypes of polycystic ovary syndrome and their association with clinical outcomes”. PCOS is not ONE condition: is a constellation of metabolic, endocrine, and ovulatory dysregulation. We covered these 4 phenotypes back then. Is this what the “new data” found? Or what it something else? And how does these affect IVF or pregnancy outcomes? Listen in for details!1. Gao, X., Zhao, S., Du, Y. et al.

• Folic Acid Update: Women on Epilepsy Meds Do NOT Need More

  Taking folic acid prior to conception and during pregnancy can help protect the unborn baby from developing abnormalities. Supplements are particularly important for women who have epilepsy, as anti-seizure medication (previously known as anti-convulsants or anti-epileptic drugs) can lead to a deficiency in folic acid. Until 2023, high doses of 4-5 mg per day were recommended. However, this has changed as the data has changed. Did you know the SMFM no longer recommends “high dose” folic acid preconceptionally for patients on seizure medications? This is also highlighted in a recently released epub from Obstetrics and Gynecology (Green Journal) on October 31, 2025. Listen in for details. 1.

• Whole Blood for PPH!

  Back on August 9, 2024, we released an episode (link in the show notes) reviewing the renewed interest in transfusing whole blood for PPH rather than component therapy. Now, in O&G open, authors from my Alma Mater (UT Southwestern) have published new data bolstering the use of whole blood for PPH. Listen in for details.1.

• Vaginal Vit C For BV? AGAIN!

  On January 18, 2020, we released an episode called “Vaginal Vit C for BV? Yep, it’s DATA”. That was 5 years ago! Now, in the Green Journal, a new systematic review and meta-analysis is examining this subject….AGAIN. Plus, this is not the only systematic review to investigate this; a similar review was published in Acta Obstétrica e Ginecológica Portuguesa earlier this year (2025) in March. So, did we get it right 5 years ago? Can vaginal Vit C help in eliminating BV? Listen in for details!1.
