By providing integrative care and cutting-edge treatment, Collab Fertility exceeds national averages

When patients begin exploring IVF, one of the first and most confusing questions they encounter is: What do IVF success rates actually mean for me? IVF success rates are one of the most searched topics in fertility care, and for good reason. Patients want clear, trustworthy information about their chances of success before starting treatment. However, these rates can be difficult to interpret without understanding what those numbers actually measure and how they apply to individual patients.

In this article, we explain IVF success rates, how IVF statistics are calculated, how Collab Fertility’s outcomes compare to national figures (hint: we are well above national averages across age groups!), and why personalized fertility care matters more than any single statistic.

What IVF statistics measure, and who they apply to

IVF statistics typically report outcomes such as pregnancy, ongoing pregnancy, and live birth rates. They are often grouped by age and may be reported per cycle, per embryo transfer, or per patient.

When reviewing IVF statistics, it’s important to ask:
– Are these IVF success rates reported per cycle, per transfer, or per patient?
– Do they measure ongoing pregnancies, live births, or both?
– Do they apply to patients using their own eggs?
– How is age factored into the data?

How Collab’s outcomes compare to national IVF success rates

When IVF success rates are compared by age group, Collab Fertility’s outcomes consistently exceed national numbers. In fact,

Collab’s IVF success rates significantly exceed national averages across all age groups, and are more than double the national average for patients over age 38

Collab reports live births and ongoing pregnancy rates, compared with national averages that reflect only live birth rates per new patient. Collab’s outcomes demonstrate how personalized, integrative fertility care can positively impact results.

What matters most is a patient’s chance of leaving with a baby once care is established. That’s why the statistics below focus on pregnancy rates per new patient using their own eggs.

 – Under age 35: 81.8% at Collab versus 50.8% nationally
– Ages 35–37: 64% at Collab versus 39.8% nationally
– Ages 38–40: 61.1% at Collab versus 27% nationally
– Ages 41–42: 36.4% at Collab versus 14.3% nationally
– Over age 42: 16.7% at Collab versus 4.2% nationally

Why Collab Fertility’s IVF outcomes stand out

IVF success is shaped by how seamlessly every part of care works together—from the first consultation to embryo transfer. At Collab Fertility, strong outcomes result from an intentionally designed, highly coordinated model of care.

A cohesive, patient-centered team

At Collab, physicians, nurses, embryologists, and support staff work as a unified team with clear communication and an investment in each person’s success. Experienced physicians and fertility nurses closely monitor patients throughout treatment. Attention to timing, coordination, and individual response—especially across the menstrual cycle—is critical to optimizing egg development and overall outcomes.

Personalized protocols at every stage

IVF is not one-size-fits-all. Collab tailors treatment plans at every phase, including initial testing, pre-cycle preparation, in-cycle monitoring, egg retrieval, and frozen embryo transfer. Factors such as age, ovarian reserve, hormone response, and prior treatment history inform individualized protocols.

Meticulous monitoring and experienced nursing care

During each cycle, Collab's providers closely follow patients, tracking hormone levels and follicle development with meticulous attention to detail. At each monitoring visit, physicians and the nursing team review ultrasound imaging and lab results together, ensuring that dosing adjustments and next steps are thoughtfully tailored to each patient. This collaborative, real-time approach allows care plans to be adjusted precisely and helps optimize each cycle as it progresses.

A state-of-the-art lab

Collab’s IVF lab is led by an on-site laboratory director and equipped with advanced technology, including a LifeAire air purification system and modern incubators with individual chambers. Strict quality control and evidence-based practices for fertilization, biopsy, freezing, and embryo culture support consistent, high-quality outcomes.

Precision at critical moments

Egg retrievals and embryo transfers require technical expertise and close collaboration between clinical and lab teams. At Collab, these steps are approached with precision and intention, ensuring alignment across teams and optimal conditions for embryo development and implantation.

IVF outcomes matter, but understanding how those outcomes are achieved provides the clearest picture of what patients can expect.

What questions should you ask during an IVF consultation?

Here are some questions you should be asking a prospective fertility clinic:

 – How will my fertility treatment be personalized?
– How does your clinic communicate with patients?
– Are your providers accessible after hours?
– How does my age and diagnosis influence my treatment plan?
– What laboratory technologies are used to support embryo development?
– Do you have an on-site lab? When was it built?
– Do you have a lab director on-site?
– How do nutrition, lifestyle, and environmental health factor into care?
– How do you define success and support patients throughout treatment?

What is the recommended number of embryos to transfer during an embryo transfer?

Another common question patients ask is how many embryos are transferred during IVF and how this affects IVF outcomes. Advances in embryo culture, genetic testing, and laboratory techniques now allow many patients to achieve strong pregnancy and live-birth outcomes with a single embryo. 

In accordance with ASRM guidelines, Collab Fertility recommends single embryo transfer, particularly when preimplantation genetic testing (PGT-A) has been performed. With high success rates using one embryo, single embryo transfer minimizes the risk of twins and other multiple pregnancies while supporting the safest possible outcomes.

Why personalized fertility care matters more than any single number

IVF success rates are influenced by many factors, including medical expertise, laboratory quality, protocol design, and the patient's age and overall health. 

At Collab Fertility, personalized fertility care is central to The Collab Way—an integrative approach that combines advanced reproductive medicine with in-house, personalized nutrition support, clean-living guidance, and whole-person care, including referrals to acupuncturists and therapists. Every Collab patient is enrolled in The Collab Way at no extra cost from the day they start treatment with us. 

By tailoring treatment plans to each individual and couple, Collab optimizes outcomes while supporting patients at every stage of their journey. IVF success rates matter, but understanding how those outcomes are achieved matters even more.
