A full-circle moment we’ll never get over 💛

Baby Theo, who was conceived right here at Collab Fertility, came back for a visit — this time running through the halls while his mom, Angie, begins the journey toward baby #2.

As a single mom by choice, Angie built her family on her own terms, and now she’s back at Collab to give Theo a sibling.

There’s something so special about watching a baby who started as a hope, a plan, and a fertility journey come back into the very clinic where it all began.

Theo may not know it yet, but he was basically giving himself the grand tour of where his story started. 💛

We’re so happy to have Angie and Theo back with us, and we're honored to be part of the next chapter of their family-building journey.

A little behind-the-scenes look at our team doing what they do best 💛

Today was a full day of egg retrievals at Collab Fertility, with Dr. Thalia Segal and our incredible lab team working together to care for each patient and every precious egg entrusted to us.

There’s so much that happens behind the scenes on retrieval day, from the procedure room to the lab, and we’re so grateful for the skill, care, and teamwork that goes into every step.

We feel incredibly lucky to do this work and to support our amazing patients through such an important part of their fertility journey.

ICSI is one of the most important tools available in the IVF lab, but it is not automatically necessary for every IVF cycle.

ICSI, or intracytoplasmic s***m injection, involves injecting a single s***m directly into a mature egg to help achieve fertilization.

It may be especially useful when there is significant male-factor infertility, very low s***m count or motility, previous poor or failed fertilization, or another specific clinical indication.

But when there is no male-factor infertility or previous fertilization problem, routine ICSI has not been shown to improve live birth rates compared with conventional IVF.

That is why we don't use the most intervention possible. It is to use the approach that makes the most sense for the individual patient.

At Collab Fertility, our clinical and embryology teams consider s***m parameters, treatment history, egg source, and the goals of the cycle when deciding how to approach fertilization.

Losing a baby at any stage of pregnancy is a profound loss.

Whether that loss happened early in pregnancy, later on, after months of hope, or after years of trying to build a family, that baby mattered. That pregnancy mattered.

And the grief that follows deserves acknowledgment.

This Pregnancy Loss Awareness Month, all of us at Collab Fertility are holding space for the women and families walking this path.

We remember the babies who did not make it earthside, and we send love to everyone carrying their memory while continuing forward in whatever way feels right for them.

For those still building their families after loss, we are here to support you with compassion, thoughtful care, and space for both grief and hope.

After trying to conceive since 2023, this sweet patient came to Collab at 42 with diminished ovarian reserve and low AMH.

After 3 rounds of IVF, they created one healthy embryo that became their baby.

Stories like this are such a powerful reminder that fertility treatment is deeply individual. Low AMH, diminished ovarian reserve, and being in your 40s can make the path more complex, but they do not tell the whole story.

We are so incredibly happy for this family and so grateful to have been part of their journey.

Could endometriosis be affecting your ability to get pregnant or stay pregnant?

In our latest Collab Journal, Dr. Deepti Nahar and Dr. Thalia Segal break down how endometriosis may affect conception, ovarian reserve, implantation, and IVF, plus when treatment or surgery may be worth considering.

One of the biggest takeaways? Having endometriosis does not mean pregnancy is impossible, but understanding how it is affecting your individual fertility picture can help you make more informed decisions.

If you have painful periods, known or suspected endometriosis, or questions about how it may affect your fertility, read the full Q&A at the link in bio.

At Collab Fertility, we take an individualized approach to fertility care and help patients understand what their diagnosis means for their goals and next steps.

10/15/2026

One of the most common things Dr. Thalia Segal hears from patients in their 40s is, “I wish I had frozen my eggs sooner.”

Fertility can decline before you feel any different, which is why learning about your ovarian reserve and egg-freezing options earlier can give you more flexibility later.

At Collab Fertility, we help patients understand where they stand now and what options may make sense for their future family-building goals.

Want to collect some facts about your fertility and get a clearer picture of your timeline? Schedule a consultation with Dr. Segal and the Collab Fertility team.

Breast Cancer Awareness Month is about more than awareness of the disease itself. It is also an opportunity to talk about what life can look like during and after treatment.

For younger patients, that may include questions about fertility, pregnancy, and the family they still hope to build.

Fertility preservation cannot guarantee a future pregnancy, and it is not the right path for every patient. But knowing your options before treatment can give you more information and more agency when so much may feel uncertain.

And fertility conversations can still matter after treatment. Current oncology guidance increasingly recognizes reproductive health as part of survivorship care, not simply something discussed once at diagnosis.

At Collab, we help patients understand those options at every stage.

10/10/2026

When someone is diagnosed with cancer, fertility preservation often becomes a race against the clock.

Our role at Collab is to make that part of the process feel as clear and coordinated as possible.

We work directly with oncology teams, help patients understand fertility preservation options, and connect eligible patients with organizations that may reduce the financial burden of care.

You are already managing enough. Fertility preservation should not feel like one more system you have to navigate alone.

This Breast Cancer Awareness Month, we’re reminding patients and providers alike: bring fertility into the conversation early.
