After three years of trying to conceive, Jennifer and Yanbo’s journey led them to IUI and a long-awaited positive pregnancy test.

Their story is a reminder that fertility care is not one size fits all. For them, success came from a thoughtful, individualized approach that combined medical expertise, education, and support every step of the way.

At Collab Fertility, we believe that understanding the full picture matters. Whether that means choosing the right treatment, adjusting the plan along the way, or simply having a team that listens, care should always be tailored to the person, not the protocol.

We are honored to be part of journeys like Jennifer and Yanbo’s, and grateful to share stories that offer hope to others navigating their own path to parenthood.

When it comes to fertility, small daily choices can have a meaningful impact.

Here are three nutrition focused shifts we often recommend when supporting fertility:

Limit added and artificial sugars.

Sugar is hidden in many everyday foods and beverages and can contribute to inflammation and blood sugar imbalance. Reading nutrition labels, choosing lower added sugar options, swapping sugar sweetened drinks for carbonated water, cutting back on sugar in coffee, and choosing whole fruit instead of juice are simple places to start.

Be mindful of caffeine intake.

Moderation matters. We generally recommend keeping caffeine under 200 mg per day, which is about 1 to 2 cups of coffee or 2 to 3 cups of black tea. This can help support healthy hormone signaling and blood flow to reproductive organs.

Increase antioxidants through food and nutrition support.

Antioxidants help protect eggs and s***m from oxidative stress and support embryo health. A diet rich in colorful fruits and vegetables, along with a high quality prenatal that includes comprehensive vitamins and adequate folate, can play an important role.

At Collab Fertility, nutrition is not an add on. It is an integrated part of your fertility plan.

This whole body approach is known as The Collab Way, where medical care, nutrition, and lifestyle support work together to support your fertility journey.

IVF success rates are one of the first things patients look at, and one of the hardest to interpret.

What do those numbers actually measure? Who do they apply to? And how much do they really say about your chances of having a baby?

In our latest Collab Journal article, we break down:

– What IVF success rates and IVF statistics really mean
– Why reporting outcomes per new patient matters
– How Collab Fertility’s outcomes compare to national averages
– Why personalization, coordination, and integrative care matter more than any single number

Across every age group, Collab’s IVF outcomes significantly outperform national averages. For patients over 38, outcomes are more than double the national average, demonstrating the impact of individualized, highly coordinated care and rigorous lab standards.

If you’re considering IVF and want clear, trustworthy information to guide your next steps, this is for you.

Not all fertility challenges are caused by egg quality, s***m quality, or embryos.

Sometime the issue is inflammation in the uterus or infection that hinders implantation.

The Receptiva test is an underutilized diagnostic tool that evaluates inflammation within the uterine lining by measuring a protein called BCL6. Elevated BCL6 levels are commonly associated with endometriosis and chronic endometritis, two inflammatory conditions that may not show up on ultrasound, routine labs, or standard imaging.

This type of inflammation can disrupt implantation and pregnancy progression, even when embryos are genetically normal and everything else appears unexplained.

At Collab Fertility, we consider advanced testing like Receptiva when appropriate as part of The Collab Way. This means looking deeper when answers are unclear and using thoughtful, evidence based tools to guide personalized care.

This test is not for everyone. But for patients with unexplained infertility, implantation challenges, or recurrent pregnancy loss, it can be an important piece of the puzzle.

If you are wondering whether deeper testing could be helpful for you, we would be honored to support you.

Miscarriages are not random, and they are never your fault.

Sometimes, the timing of a pregnancy loss can offer clues about what the body may need more support with. Not definitive answers, but helpful information that can guide testing and care.

Very early losses may point toward implantation support, hormone balance, or egg and s***m quality.

Early first-trimester losses can be related to chromosomal factors, immune balance, or blood flow.

Later losses may suggest placental development, clotting conditions, or autoimmune factors.

At Collab Fertility, this is part of The Collab Way. We take a whole body approach to fertility and miscarriage care, looking beyond one lab or one moment in time.

That means evaluating hormones, genetics, immune health, blood clotting, nutrition, lifestyle, and both partners, so we can create a plan that supports your body more fully.

If you have experienced one or more pregnancy losses, you are not alone. And there may be more information available to help guide your next steps.

We would be honored to support you on your journey.

“Happy New Year Dr. Segal and Collab Team!

December came and went, and I wanted to reach out on our 1 year anniversary of being your patient! 1 year ago this December, you helped in making my dream of being a momma come true! Through losses, an emotional rollercoaster, labwork stress, and oh so much more your heart and understanding for individualizing my care was the best gift. I’m so grateful. Cheers! To my lucky #7. Can’t wait for Theo’s sibling to join us.”

Being a single mom by choice is an incredibly empowering journey, and we are honored to support Angie and her growing family. Angie conceived through IUI with donor s***m, a path that reflects both intention and hope, and we are so grateful to continue walking alongside her as she prepares to welcome Theo’s sibling.

Moments like this are why we do what we do. We are grateful every day to witness miracles like these at Collab Fertility, and we would be delighted to support you on your journey to parenthood.

A little miracle on the way and a journey worth celebrating.

This holiday card and ultrasound capture so much more than a season. They reflect over a year of hope, patience, and perseverance.

After trying to conceive for more than a year, this 33 year old patient with PCOS came to us for support. With a personalized plan including letrozole and timed in*******se, she conceived during her second month under our care.
Now, as they prepare to welcome their baby girl in May 2026, moments like this remind us why we do this work. It is an honor to walk alongside our patients through pregnancy milestones and beyond.

If you are on your own fertility journey, know that you are not alone. The Collab team would be honored to support you with thoughtful, individualized care every step of the way.

As we head into the new year, we’re proud of what we’ve built since opening in February 2024 and grateful for the patients and partners who continue to place their trust in us. We look forward to continuing this work with intention, collaboration, and care in the year ahead.

Some updates stop us in our tracks and remind us why we created Collab Fertility.

“I just hit 18 weeks, and the baby is growing and healthy. The baby was waving its little arm.”

After a long and deeply personal fertility journey, Suzy is now 18 weeks pregnant with a healthy baby, and we are so honored to share this moment with her permission.

At 42, Suzy came to Collab Fertility after years of infertility. Her partner was diagnosed with a Y chromosome microdeletion in the AZFc region. Through advanced care, including microTESE with our urology partners and ICSI, healthy s***m were successfully retrieved, and eggs were fertilized, resulting in viable embryos.

It took two embryo transfers. Between the first and second, Suzy made a deep commitment to lifestyle and nutrition changes while working closely with our in-house nutritionist. Her hemoglobin A1c improved, her body was better supported, and on the second transfer, she conceived.

This is what individualized, collaborative fertility care looks like.
Advanced science. Lifestyle support. Persistence. Hope.

We are so grateful to walk alongside patients like Suzy and to celebrate moments like this together.

Experiencing recurrent pregnancy loss can feel devastating, confusing, and isolating. Many people wonder if something is wrong with their body or if there is anything that can actually help prevent another loss.

At Collab Fertility, we support patients navigating recurrent miscarriage with compassionate, evidence-based care that looks at the whole picture. Through comprehensive testing and personalized treatment, our team can identify a likely cause in about 50 percent of cases. Even when a clear cause is not found, many patients go on to have healthy pregnancies with the right support.

In our latest blog post, we break down:

• What recurrent pregnancy loss is and how common it really is
• Possible causes include genetic, uterine, autoimmune, hormonal, and lifestyle factors
• How age and chromosomal changes can impact miscarriage risk
• When IVF and genetic testing may be helpful
• When it is time to seek evaluation, and what testing may look like

Led by Dr. Thalia Segal, our team takes the time to understand your story and guide you forward with clarity, care, and confidence.

If you have experienced multiple losses, please know this is not your fault, and you deserve answers and support.

12/26/2025

We are proud to share that Dr. Thalia Segal has been selected to serve on the ACOG District IX Committee on State Legislation.

As a reproductive endocrinologist and long-standing advocate for women’s health, Dr. Thalia has spent the past decade advancing research, education, and advocacy around the reproductive impacts of endocrine-disrupting chemicals and environmental toxins.

From founding evidence-based, integrative care models to supporting funded research on plastic and pesticide exposure in fertility care, her work has consistently focused on one goal: translating science into meaningful action that protects patients, families, and future generations.

This appointment reflects a commitment to shaping evidence-based policy that addresses environmental exposures many communities face every day, often without awareness or adequate protection.

We are honored to see her expertise contribute to ACOG’s mission of improving women’s health through advocacy, education, and legislative leadership.
