Tonight, families around the world will light a candle at 7pm to remember babies lost during pregnancy or infancy. It's called the Wave of Light, and October 15 is Pregnancy and Infant Loss Awareness Day.

If this is part of your story — however that looks for you — we see you tonight. 🕯️

No two losses are the same, and there's no timeline for how long they're allowed to stay with you.

We're lighting a candle tonight too. 🤍

October is Pregnancy and Infant Loss Awareness Month. 🤍

Behind every pregnancy is a story. And behind every loss is one, too.

A name that may have already been chosen. A due date circled on the calendar. A future that was already being imagined.

At STL Fertility, we know that pregnancy and infant loss are deeply personal. For some members of our team, that understanding comes not only from caring for patients, but from our own experiences with loss.

This month, we're honoring the babies who are deeply loved and remembered, and the families who carry their memory.

We've shared a new blog about navigating grief, finding connection, and accessing support, including resources here in St. Louis.

Whether your loss happened recently or years ago, whether you share your story openly or carry it privately, your experience matters.

To every family who has experienced pregnancy or infant loss: We see you. We remember with you. And you are not alone. 🕯️

Recurrent pregnancy loss just got a real update from the American Society for Reproductive Medicine — and it changes what “counts.” Here's what you need to know, in plain language. 📋

For the first time since 2012, ASRM has revised its national guidance on recurrent pregnancy loss (RPL). Two things worth knowing if this touches your story:

✅ The definition now formally includes biochemical pregnancy losses — a positive test that didn't progress — even without ultrasound confirmation. If a loss ever felt dismissed because there was “nothing to see” on a scan, this update says it still counts, and so does your grief.

✅ New data also links RPL to a higher lifetime risk of a few other health conditions — cardiovascular disease, diabetes, autoimmune and mental health conditions among them. That's part of why a full RPL evaluation looks at the whole picture of your health, not just the next pregnancy.

We believe you deserve to understand exactly why we test what we test — not just be told to trust us. This month, we're going deeper into what this update means for how RPL actually gets evaluated. Starting here. 🤍

A team that doesn't let go until you have your answer. A patient who came back to tell us there's a second one on the way. That's what this looks like from the inside.

"They are your biggest supporters and cheerleaders. Their goal: figure out what's going on, get it fixed, and help you become a parent. They don't treat you like a number but like a person." — FertilityIQ review

"The path of infertility can be lonely, but at STL Fertility I found hope. I have a beautiful almost 2 year old boy and am expecting another — both with STL Fertility." — Le., STL Fertility patient ⭐⭐⭐⭐⭐ Google

Closing out PMOS (formerly PCOS) Awareness Month by clearing up the myths that hold too many people back. Save this, share it with someone who needs it. 🎗️

❌ MYTH: PMOS means you can't get pregnant.

✅ FACT: PMOS is one of the most treatable causes of infertility. Many patients conceive with ovulation induction alone.

❌ MYTH: PMOS is caused by being overweight.

✅ FACT: PMOS is a hormonal and metabolic condition. It affects people at every body size, and weight is not part of the diagnostic criteria.

❌ MYTH: If your ultrasound looks normal, you don't have PMOS.

✅ FACT: You only need 2 of 3 diagnostic criteria. Ovaries can look completely normal and PMOS can still be present.

❌ MYTH: There's nothing to do about it besides birth control.

✅ FACT: Treatment is built around your goals — fertility, cycle regulation, or metabolic health — and looks different for every patient.

This condition affects roughly 1 in 8 people with ovaries, according to the Endocrine Society. If this is you, you are far from alone. 🤍

Three WHNPs. One incredible care team. 🤍

There are a lot of moments between the big appointments in fertility care — monitoring visits, ultrasound results, questions about medications, waiting for next steps, and sometimes just needing someone to remind you that you’re doing okay.

That’s where this team comes in.

Melanie, Mackenzie, and Ellie are all board-certified Women’s Health Nurse Practitioners, and they are an incredible part of the team surrounding our patients every step of the way.

They’re reviewing results with you.
Explaining what they’re seeing.
Answering your questions.
Monitoring your progress.
Celebrating the good days.
Supporting you through the hard ones.
And always willing to go the extra mile for your care.

At STL Fertility, you’ll have a provider at every monitoring visit — because you deserve to understand what’s happening and have someone there to talk through it with you.

We’re so lucky to have Melanie, Mackenzie, and Ellie caring for our patients — and cheering them on along the way.

You've met our newest Nurse Practitioner. Now let's actually get to know her. 🤍

One of the things we care deeply about at STL Fertility is that the people taking care of you never feel like strangers. So before Mackenzie starts meeting more of you in the exam room, we asked her a few questions...

1. Why fertility care?
"I've always been drawn to women's health, and fertility care feels like such a meaningful combination of medicine and incredibly personal patient care. I love that there are so many opportunities to educate and help families feel confident, informed, and supported during what can be such an overwhelming process."

2. What do you hope a patient feels when they leave an appointment with you?
"My goal is always to create a space where you feel comfortable, supported, and seen. Fertility care comes with so much uncertainty and emotion; it's okay to be nervous. There's no such thing as a "silly question," and I will meet you where you are."

3. What do you like to do when you are not caring for patients?
"I'm usually hanging out with my husband and our dog, Obi. I also have over 30 house plants that I love to take care of in my spare time. My favorite thing to do on a weekend is to go to Maypop Coffee Shop and walk through their greenhouse with a vanilla latte in hand 🙂 "

Wondering how a PMOS (formerly PCOS) diagnosis actually gets made? Here's exactly what we look for — no guesswork. 🔬

PMOS is diagnosed using the Rotterdam criteria — you need at least two of these three:

✅ Irregular or absent ovulation

✅ Signs of elevated androgens (labs or symptoms like acne, excess hair growth)

✅ Polycystic-appearing ovaries on ultrasound

Notice what's not on that list: weight. PMOS is not diagnosed based on body size, and you don't need to 'look a certain way' to have it.

At STL Fertility, that workup happens with a physician r who reviews your results with you.

Every provider on our team, MD and NP alike, is trained to diagnose and manage PMOS thoroughly. You'll never wonder who's actually looking at your case.

Getting a real answer can feel like a relief on its own — we're honored to be the ones who give it to you. Save this for your next appointment prep. 📌

We have someone new for you to meet. 🤍

Please join us in welcoming Mackenzie Shawgo, WHNP-BC to the STL Fertility family!

Mackenzie joins our growing Nurse Practitioner team, bringing her knowledge, compassion, and commitment to caring for patients through every step of their fertility journey.

At STL Fertility, our WHNPs are an incredibly important part of how we care for you. They work closely alongside our physicians, see patients for monitoring visits, perform ultrasounds, review results with you in the room, and help make sure you leave knowing what comes next.

And now, we're so excited to have Mackenzie joining that team.

You'll be seeing much more of her around here — and we can't wait for you to get to know her. Welcome to the family, Mackenzie! 💛

Can s***m actually sense temperature? 🌡️🔬

Some fascinating fertility science has been making headlines recently — and this one has a St. Louis connection.

Researchers at WashU Medicine studied CatSper, a calcium channel in the s***m tail that plays an essential role in the hyperactivated movement s***m need for fertilization.

Their research found that CatSper is temperature-sensitive, adding another piece to our understanding of how s***m regulate when to activate some of the machinery needed for fertilization.

Pretty incredible.

But here's something we think is equally important when you see headlines about new fertility research:

Interesting science does not always mean a new treatment.

This discovery deepens our understanding of s***m biology and may eventually help researchers better understand certain forms of male infertility — but it doesn't change fertility care overnight.

That's how science works. We ask a question. We learn something new. We test it again. And over time, those discoveries can change the way we understand and practice medicine.

And we especially love that this work came from researchers right here at Washington University School of Medicine in St. Louis. ❤️

We'll always be watching the science — and helping our patients understand what it actually means.

Science. Support. Success.
