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 becoming a viable option thanks to advances in culture systems and vitrification. Most importantly, Dr. Amols puts these odds into perspective: while Day-7 embryos aren’t front runners, many healthy babies have still been born from them.

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 — including studies where the chip nearly doubled live birth rates in male-factor infertility, and others where it made little difference in unselected IVF populations.
• Which patients benefit the most: men with high DNA fragmentation, couples with male-factor infertility, and those with failed fertilization or poor embryos in past cycles.
• Practical considerations — cost, limitations, and why some clinics use it for everyone while others use it selectively.

Is it a true game changer, or just another lab gadget? Tune in to find out.

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 lab and an “18” in another, and why most fertility specialists still treat it as a tiebreaker — not a dealbreaker.

Whether you're mid-IVF or mitochondria-curious, this episode is packed with helpful info, analogies, and (of course) tacos.

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. From the tiny gestational sac to the yolk sac (your baby’s first lunchbox), to the fetal pole and that reassuring flicker of a heartbeat, Dr. Amols explains what each step really means and when you should expect to see it. You’ll also learn:

• Why we stop checking hCG once we see the sac
• What it means if a yolk sac is missing or measures unusually small or large
• How to understand the fetal pole and when to expect a heartbeat
• Growth benchmarks from “grain of rice” to “strawberry”
• Why being 3–7 days behind may (or may not) be concerning
• How and why the placenta forms, and when we can actually see it
• What nuchal translucency is, what causes it, and what it does—and doesn’t—mean

One ultrasound is just a snapshot, but together they create the story of the first trimester. If you’ve just found out you’re pregnant—or you’re supporting someone who has—this episode will help you decode what’s on the screen and know what to expect in those exciting early weeks.

You finally got the positive test after IVF or IUI — now what? 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. Learn why rising numbers matter more than the absolute hCG value, why it’s crucial not to stop progesterone or estrogen too early, and what milestones to expect in the first 6–10 weeks.

Dr. Amols also shares common myths, tips for healthy habits, and insight into the emotional rollercoaster of “graduating” from your fertility clinic to your OB.

Understanding the different types of Diminished Ovarian Reserve and what they mean for your fertility journey

Being told you have Diminished Ovarian Reserve (DOR) can feel overwhelming — but the truth is, it’s not the same diagnosis for everyone. In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols breaks down the “automobile” analogy to explain why DOR is a broad category that can mean very different things depending on the cause.

You’ll learn:

• The four common “models” of DOR and how each affects fertility
• Why age, AMH, AFC, and FSH tell different parts of the story
• How your specific type of DOR shapes your treatment plan
• Real patient stories that prove DOR doesn’t always mean poor outcomes
• The essential questions to ask your doctor if you’re diagnosed with DOR

If you or someone you know has been labeled with DOR, this episode will help you replace fear with clarity — and empower you to make the right next step for your situation.

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

But for Dr. Mark Amols, there’s one part that truly keeps him up at night—fertilization.

In this deeply personal episode of Taco Bout Fertility Tuesday, Dr. Amols shares why fertilization is the most unpredictable and emotionally gut-wrenching step in the entire IVF process. You’ll get a crash course in reproductive biology—meiosis, pronuclei, 0PNs, 2PNs, and more—and learn what really happens the night sperm meets egg.

He explains:

• Why even perfect sperm and eggs can fail to fertilize
• The terrifying uncertainty of ICSI and why it doesn’t guarantee success
• How fertilization failure happens—and why it feels like a blindside
• What embryologists look for when checking for normal fertilization
• The brutal truth about age, egg quality, and cellular death

Whether you’re preparing for IVF, recovering from a failed cycle, or just want to understand the science behind the scariest moment in the lab, this episode delivers the insight—and honesty—you won’t hear anywhere else.

Where did the semen go? In this week’s episode of Taco Bout Fertility Tuesday, Dr. Mark Amols unpacks one of the lesser-discussed causes of male infertility—low semen volume and retrograde ejaculation.

From the science of what makes up semen (spoiler: sperm is only about 3% of it!) to the coordinated dance between the sympathetic and parasympathetic nervous systems, you’ll learn how the body decides when to open and close the right channels during urination and ejaculation.

We break down:

• What qualifies as “low volume”
• How retrograde ejaculation happens—and how to spot it
• Conditions like diabetes, surgeries, and medications that can cause it
• Diagnostic tools including post-ejaculatory urinalysis
• Treatment options including Sudafed, sperm retrieval, and IVF/ICSI
• Other causes of low volume like ejaculatory duct obstruction and congenital absence of the vas deferens

Whether you're a patient, partner, or just curious about how sperm can get lost in transit, this episode is full of insight, clarity, and of course—compassion and tacos.
