Hear from the Collab community

I can’t say enough good things about my experience at Collab. Dr. Segal and the whole team are incredible! From our first meeting I really felt that Dr. Segal listened to my concerns and goals and took the time to get to know me as a person and a patient. Everyone on the team is so kind and compassionate. The level of communication is excellent and far exceeds what I’ve experienced at other fertility clinics in the past. The facility is beautiful and comfortable which is a really nice bonus too!

CASEY S.

My husband and I are absolutely blown away by Collab Fertility and Dr. Segal! From our first meeting, I was immediately struck by her compassion, clear expertise, kindness, and exceptional communication. Having been through the difficult process of IVF for over a year and using two other clinics, I speak from experience that there is NO ONE better than Dr. Segal and her clinic. We hope that through our own experience, others can benefit in their fertility journey like we finally now are.

FAQ

What is infertility?

Infertility is the inability to conceive a child after one year (or six months, for women over the age of 35) of regular, timed unprotected intercourse. It can affect both men and women and may result from issues with the reproductive systems of either partner.

What is IVF?

In vitro fertilization (IVF) is a type of assisted reproductive technology (ART) used to help individuals or couples conceive a child. The process involves fertilizing an egg with sperm outside the body in a laboratory setting. IVF is often used when other fertility treatments have been unsuccessful or when there are specific fertility issues such as severely low sperm counts or blocked fallopian tubes.


How do Collab Fertility’s IVF success rates compare to national averages?

Collab Fertility’s IVF pregnancy rates consistently exceed national averages across multiple age groups, based on reporting benchmarks from SART (Society for Assisted Reproductive Technology). These outcomes reflect our experienced embryology team, state-of-the-art IVF lab, and highly personalized approach to fertility care.

You can explore a full breakdown of our IVF success rates by age group and learn more about how outcomes are measured on our Success Rates and Stories page.


What is egg and embryo freezing?

Egg and embryo freezing are both ways of collecting and storing our gametes so that they can be later used to initiate a pregnancy.

Both start out with an egg retrieval process, where eggs are collected from the ovaries. In the case of egg freezing, mature eggs are frozen. They are later thawed and then fertilized before being implanted into the uterus of the person who is aiming to become pregnant.

With embryo freezing, the mature egg is fertilized using sperm from a partner or sperm donor, and then frozen. When it’s time for implantation, the embryo is thawed and then transferred.

The main difference between egg and embryo freezing is whether the egg gets fertilized now, or later.


What is the process for IUI?

The IUI process involves several steps to optimize timing and increase the chances of conception.

  1. Cycle Monitoring & Medication
  2. You will report the first day of your cycle and begin taking the prescribed medications (if applicable).
  3. Around Cycle Day 10 or 11 (for a Clomid/Letrozole cycle), you will come in for a mid-cycle ultrasound.
  4. Mid-Cycle Ultrasound
  5. A vaginal ultrasound is performed to assess:
  6. Number of follicles
  7. Follicle size
  8. Uterine lining thickness
  9. This helps determine when to take the Ovidrel (hCG trigger) injection to time ovulation accurately.
  10. Trigger Shot & Insemination Appointments
  11. You will be instructed on when and how to self-administer the Ovidrel injection.
  12. If using a partner’s sperm, you will receive two appointments:
  13. Sperm collection (if fresh sample is used)
  14. Insemination procedure (IUI)

Your provider will guide you through each step and ensure everything is timed correctly for the best possible outcome.

What makes Collab Fertility different from other fertility clinics?

Collab Fertility combines advanced reproductive medicine with a more personalized, whole-person approach to care called The Collab Way. In addition to IVF and fertility treatment, our team helps patients navigate factors like nutrition, environmental exposures, lifestyle, and emotional wellbeing through collaborative support and individualized treatment plans.


What is fertility testing?

Fertility testing includes blood work, tubal patency testing, and an ultrasound. Male fertility testing includes blood work and a semen analysis. These tests evaluate an individual's or couple's ability to conceive, providing a clearer picture of reproductive health and recommended treatment.

What is the average cost of fertility treatment?

The cost of fertility treatment varies depending on the procedure and your insurance coverage. We recommend scheduling an initial consultation to discuss your options and create a personalized treatment plan.

Do you offer fertility financing?

Yes. We partner with PatientFi, CapexMD, and Maven Wallet to offer flexible financing options for fertility treatments. Our financial counselors can also help you understand your insurance coverage, maximize fertility benefits, and explore available discount programs.

Do you accept insurance?

Collab is in-network with United Healthcare, Cigna, Hill Physicians, Health Net, and Carrot. For non-contracted health plans, we will provide a detailed receipt of services and will help you submit directly to your insurance carrier to maximize any reimbursement.

How soon can I start fertility treatments?

The timeline for starting fertility treatments varies depending on how quickly certain steps are completed. One of the lengthier steps is genetic carrier screening, which typically takes about three weeks for results. After receiving those results, you’ll meet with a financial counselor and then with a nurse to finalize the next steps.

Do you have a waitlist?

No. We do not currently have a waitlist for new patient consultations or fertility treatments. Our team works to provide timely access to care so you can move forward without unnecessary delays.
