In today's episode of Health Youniversity, Dr. Susan Fox sits down with Dr. Katie Worrilow — founder and Chief Scientific Officer of Life Air Systems, postdoctoral-trained reproductive physiologist, and former scientific director of IVF programs for over 20 years — for a conversation that will change how you think about your IVF cycle.

Dr. Katie spent twenty years noticing something. That when construction began outside the hospital, when the medevac pad got repaved, when the parking lot was resurfaced — clinical pregnancy rates dropped. Not because of the medicine. Not because of the protocol. Because of the air surrounding the embryo during the most critical six to seven days of its existence outside the body. That realization became Life Air Systems — a patented air purification technology now installed in 41% of US IVF programs, awarded 23 patents, over 60 registered trademarks globally, and the 2025 Edison Award for innovation in healthcare.

The data from clinical studies across several thousand patients showed a nearly 20 percentage point increase in clinical outcomes with complete air quality control. Across the full installation base worldwide, the average increase in clinical pregnancy rates is 14.9 percentage points — with corresponding improvements in implantation rates and blast conversion rates.

You'll learn why the air surrounding a human embryo during culture matters. Why the environment, and chemical pathogens like toluene from warm asphalt do to embryo development — and why you won't see the damage at day 3, only at day 5. Blastocyst conversion rates and implantation rates are the metrics that tell the real story — air quality has to do with both. And you’ll learn what questions to ask your IVF clinic before your next retrieval or transfer about air quality at the transfer stage, why the same variable that improves outcomes also reduces the likelihood of needing multiple retrieval cycles — and what that means financially and emotionally. And you’ll understand why Dr. Susan is calling out fertility insurance providers and employee benefits managers in this episode directly.

This episode is for you if you're preparing for an IVF cycle and want to do everything possible to optimize your outcome, you've had a beautiful day 3 embryo report followed by a devastating day 5, you've been through one or more failed cycles and are trying to figure out what to do differently before the next one, you want

In today's episode of Health Youniversity, Dr. Susan Fox sits down with Zsofia Jamieson and Marta Han — co-founders of The Fertility Class and certified teachers of the Aviva Method — for a conversation about something most fertility conversations completely skip: movement.

Zsofia was diagnosed with severe PCOS as a teenager and told she might never conceive. She healed naturally through movement and nutrition, eventually bringing the Aviva Method from Hungary to the UK and the US. Marta navigated hypothalamic amenorrhea and years of infertility tied to over-exercising and undernourishment, yet restored her cycle through holistic practice. A decade after meeting in a London playground, they built The Fertility Class — a cycle-synced, pelvic-centered movement platform now reaching women worldwide.
This episode is about what rhythmic pelvic movement actually does to the reproductive system — and why it's one of the most underused tools in the fertility conversation. Blood flow. Hormonal axis regulation. Reflexology point stimulation. Nervous system support. Emotional release. All from 30 minutes of movement, three times a week.

You'll learn what the Aviva Method is — a therapeutic movement practice developed by a Hungarian physiotherapist and ballet dancer in the 1960s with over 25 years of research behind it, why pelvic-centered movement is categorically different from yoga, kegels, or cycle-synced exercise — and what it actually does to the follicular environment, how rhythmic contraction and release of the lower belly muscles increases blood flow to the uterus, fallopian tubes, and ovaries, why the hypothalamic-pituitary-ovarian axis responds to specific movement and reflexology point stimulation, why sitting 8 to 10 hours a day is quietly affecting your fertility markers. And why the fertility class also has a men's program — (because male factor accounting for 40% of infertility).

This episode is for you if you've been doing "all the right things" fertility-wise but haven't addressed how you're moving — or not moving, if you have PCOS, irregular cycles, painful periods, or hypothalamic amenorrhea and want to understand what movement can do, if you're heading into IVF and want to improve your markers and your outcomes before your first appointment, and if you’re ready to start relating to your body as something worth moving for.

In today's episode of Health Youniversity, Dr. Susan Fox sits down with Ashley Statchon — yoga teacher, fertility and prenatal specialist, oncology yoga instructor, and director of Metta Mama — for a conversation that starts with the nervous system and ends somewhere most fertility conversations never go.

Ashley came to yoga as a competitive gymnast looking for a physical challenge. What she found was something that would reshape how she understood the body entirely — and years later, when a breast cancer diagnosis at 43 put everything to the test, it was breath, movement, and the practices she'd been teaching that carried her through. Today, she brings that lived experience into fertility yoga, prenatal care, postnatal support, and oncology.

This episode is about what yoga actually does to and for the body as a nervous system intervention. Why cortisol timing matters. Why 70% of the information flowing through your central nervous system travels from body to brain, not the other way around. And why trying to think your way out of a stress cycle is, biologically speaking, unlikely to work.

You'll learn what fertility yoga is and why it's relevant - whether you're just beginning to think about conceiving or deep in an IVF cycle. You’ll also understand healthy cortisol rhythms — and how most of us derail those rhythms before breakfast. You’ll learn that the psoas, hamstrings, and pelvic floor hold the stress cycle in the body long after the moment has passed, what legs up the wall actually does physiologically. Ashley shares how breath, meditation, and visualization stabilized her liver enzymes during chemotherapy — and what that taught her about the body's capacity to respond,. We discuss that research shows infertility carries the same measurable stress load as a life-threatening diagnosis — and what ahimsa — nonviolence — looks like when you turn it toward yourself.

This episode is for you if you've been wondering if yoga improve fertility beyond flexibility and relaxation, if you're navigating IVF or IUI and want to know what you can do in your own body to support the process, if you feel chronically wired but exhausted or if, you or someone you love is navigating a cancer diagnosis alongside a fertility journey. If you're in the Bay Area, attend Ashley's in-person eight-week fertility yoga series at Metta Mama.
