Dr. Chapa’s OBGYN Clinical Pearls

Platelet-rich plasma (PRP) injections do not have formal FDA approval for specific clinical indications. PRP is regulated as an autologous blood product and is used "off-label" in clinical practice. However, there is substantial clinical evidence supporting its use for certain dental surgeries and musculoskeletal conditions, particularly lateral epicondylitis, knee osteoarthritis, and plantar fasciitis. The American Medical Society for Sports Medicine notes that PRP is primarily used to treat tendinopathies and osteoarthritis, though clinical efficacy results remain mixed due to variability in PRP formulations and preparation methods. As of now, there are no FDA approved uses for PRP for gynecologic use, although there has been some evidence of possible benefit in vulvar dermatoses and possiblt ovarian function enhancement. But what about its use in the vagina for sexual pleasure? Injecting into the anterior vaginal wall (around the famed G-Spot location) is nothing new. Over a decade ago, a TV show introduced the masses to the “G-Spot amplication” shot which injected collagen to that area. But there was no data for this. Well, we are back to this idea in a new RCT in the Green Journal. Can PRP light up the vaginal fires of pleasure? Listen in for details.

Podcast family, welcome to Quickie #4. This one will be fun: A. Medicine changes, and changes fast. I trained with and learned the Grannum grading placental system (grades 0-III based on ultrasound appearance). Is that still a thing? We recently found a “grade III placenta at 34 weeks” as an incidental finding. Is there specific management considerations for this? Listen in for details. B. What do we do when a patient has “two GBS results” in one pregnancy hat are discordant. Listen in for that as well!

Well, it's no doubt we live in a culture of immediate gratification. When we need to know something, we must know it immediately! This even applies to couples seeking pregnancy and their desire to find out if their monthly attempts have been successful. However, there is a problem with trying to prove pregnancy too promptly. In this episode, we will review a new publication just released on March 1st, 2026 out of the Green journal. These authors evaluated a prospective cohort (PRESTO cohort) of pregnancy planners to analyze their pregnancy test taking behaviors and their outcomes. The results are eye-opening. So, when is the best time to check a pregnancy test? Listen in for details.

What an AMAZING lesson, Podcast Family, in this impromptu episode, we will hear from one of my former medical students, now BOARD-CERTIFIED OBGYN...and an incredible OB case she just had. Sometimes....we find ZEBRAS! Great job, Lauren!

Podcast family we've all heard the rumors that oursmartphones are “LISTENING TO US”. Well, some of that is actually true, and trust me I'm not a conspiracy theorist. Our smartphones are capable of remarkable things. A new publication from the Green journal (released ahead ofprint on 03/05/2026 ) is proposing that it may now be able to detect fetal movement, fetal breathing, and even fetal hiccups when placed over the abdomen! Yep, it's not science fiction... it's science innovation. While this is not ready for prime time just yet, the science is absolutely astounding. In this quicky episode we will briefly summarize a fascinating new innovative study which proposes that our iPhones may be able to be a fetal movement detector.
