Send us a text Are fertility clinics telling you the whole truth about their success rates? In this episode, Dr. Mark Amols breaks down the hidden math behind IVF statistics — and exposes how “creative marketing” can make average results look amazing. Learn why pregnancy rates don’t always mean babies, how clinics use “per transfer” versus “per cycle” numbers to their advantage, and what to look for in real CDC data before choosing a fertility center. From the “we take the toughest patients” ...
Send us a text Not all fertility pills are created equal. In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols breaks down the real differences between Clomid (clomiphene citrate) and Femara (letrozole)—two medications that may look the same but work in totally different ways. Learn how each medication triggers ovulation, why increasing your dose doesn’t always improve your chances, and when doctors decide to switch from oral pills to injectable gonadotropins. Dr. Amols also shares ...
Send us a text Freezing is one of the most powerful tools in modern fertility—but it’s also one of the most misunderstood. In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols unpacks the science behind freezing sperm, eggs, and embryos. Why do eggs and embryos need vitrification while sperm are slow-frozen? Does freezing harm fertility? Why can’t multiple sperm samples just be frozen and combined for IUI? And does the length of time embryos are frozen affect success? From the histo...
Send us a text ICSI—also known as intracytoplasmic sperm injection—sounds complicated, but it’s one of the most powerful tools in modern IVF. In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols breaks down what ICSI really is (hint: it’s the ‘needle in the egg’), when it’s a game-changer, and when it might just be an unnecessary add-on. From male factor infertility to frozen eggs, genetic testing, and even rescue ICSI, you’ll learn exactly when this treatment makes sense and when i...
Send us a text Are Day-7 embryos doomed to fail — or are they just late bloomers? In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols explains why embryos that don’t reach blastocyst until Day 7 have lower implantation and live birth rates compared to Day 5 or 6. Using a marathon analogy, he breaks down how timing reflects embryo quality, metabolism, and chromosomal health. You’ll also hear the surprising history of Day-7 embryos — from being discarded in the early 2000s to becomin...
Send us a text In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols takes a deep dive into the ZyMōt microfluidic sperm chip — a device designed to mimic nature’s way of selecting the healthiest sperm. We explore: Why sperm DNA fragmentation matters for fertilization, embryo quality, and miscarriage risk.How the ZyMōt chip works compared to traditional methods like swim-up and density gradient centrifugation.What the science really shows — from lab data to clinical trials — includin...
Send us a text Today’s episode comes straight from a listener question: What’s the deal with MitoSure? Is this mitochondria-based score the secret weapon in embryo selection — or just another lab test with a fancy name and fuzzy usefulness? Join Dr. Mark Amols as he takes you on a wild science ride from embryo scoring to evolutionary biology, bacterial roommates, and the ancient origin of mitochondria. You'll learn what MitoSure actually measures, why the same embryo could score a “2” in one ...
Send us a text In this week’s episode of Taco Bout Fertility Tuesday, Dr. Mark Amols takes you on a guided tour of your baby’s very first pictures—the first trimester ultrasound.

In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols walks you through the first steps after a positive pregnancy test, from confirming with beta hCG bloodwork to your first ultrasound.

Send us a text There’s a lot to worry about in IVF: Will you get enough eggs? Will your embryos be normal? Will the transfer work?
