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.

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.

Packed with analogies, real patient stories, and just enough nerdy data to make you feel smarter than your doctor’s EMR, this episode is for anyone riding the emotional rollercoaster of fertility treatment.

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.

From hormonal red flags and testicular trauma to lifestyle choices and personal history, this episode breaks down when men should consider that they might be the reason pregnancy isn’t happening.

Whether you’ve been “lucky” to avoid pregnancy in every relationship or just assumed things were working fine because, well, you feel fine — it’s time to check the scoreboard.

No blame. Just facts, awareness, and a gentle reminder: sometimes the strongest move a man can make… is handing over a cup.

You’ve heard of estrogen, maybe even LH—but the real superhero in fertility? It’s progesterone.

In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols reveals how progesterone silently supports pregnancy, stabilizes the uterine lining, and prevents early contractions—all without the recognition it deserves.

We break down the science: how progesterone is made from cholesterol, how it converts into testosterone and estrogen, and how granulosa and theca cells work together to build a pregnancy-ready uterus.

Plus, Dr. Amols explains why blood levels may look “low” on vaginal progesterone, why that doesn’t mean treatment failure, and why route of delivery really matters—especially in frozen embryo transfers.

Whether you're trying naturally, doing IUI, or planning an FET, this episode will help you understand what progesterone is really doing behind the scenes—and why it might just be the most important hormone you never thought about.

You've been told your sperm shape is the problem—but is it really? In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols breaks down what sperm morphology actually means, how it's measured, and whether a low morphology score truly impacts your chances of getting pregnant.

We’ll explore:

• What “teratozoospermia” is—and why it sounds scarier than it is
• Why a 1% morphology score might still be totally fine
• The truth about IUI and IVF outcomes when morphology is low
• When ICSI is used defensively vs. when it’s really necessary
• What the studies actually say about fertilization and live birth rates

If you or someone you love has been told poor morphology is a dead end, this episode may change the way you see the path forward.
