How Women Can Improve Their Fertility & Hormone Health | Dr. Natalie Crawford
Dr. Natalie Crawford discusses actionable steps for improving women's reproductive and hormone health. She emphasizes fertility as a health marker, advocates for AMH testing for all women wanting children, explains egg quality versus quantity, and provides lifestyle recommendations for optimizing fertility including sleep, nutrition, and toxin avoidance.
Summary
Dr. Natalie Crawford, a double board-certified physician specializing in fertility and reproductive health, discusses comprehensive approaches to women's reproductive and hormone health. She begins by framing fertility as an important health marker rather than just the ability to get pregnant, explaining that infertility correlates with increased rates of metabolic syndrome, cancer, and early death due to underlying chronic inflammation and insulin resistance. Crawford advocates strongly for all women wanting children to get AMH (anti-Müllerian hormone) testing, despite medical guidelines recommending against it, arguing that the $79 test provides crucial information about egg count that can inform life decisions. She explains the biology of egg quality versus quantity, detailing how eggs are stored in ovarian 'vaults' and how both age and metabolic health affect egg competency. The discussion covers her 'five non-negotiables' for optimizing fertility: sleep (7-9 hours with consistency), stress management, building muscle mass, anti-inflammatory nutrition, and toxin avoidance. She addresses common misconceptions, such as egg freezing depleting ovarian reserve (it doesn't) and NSAIDs preventing ovulation when trying to conceive. Crawford discusses various birth control methods' effects on fertility, the importance of tracking ovulation beyond just menstrual cycles, and emerging treatments like GLP-1 agonists for chronic inflammatory conditions affecting fertility. She emphasizes that lifestyle factors significantly impact both male and female fertility, particularly highlighting the detrimental effects of cannabis and nicotine use on sperm quality and pregnancy outcomes.
Key Insights
- Crawford argues that AMH testing should be available to all women wanting children despite medical guidelines against it, calling it a crucial $79 test that provides important information about egg count and reproductive timeline
- Crawford explains that egg freezing does not deplete ovarian reserve because it only captures eggs that would naturally be lost each month, working with eggs already outside the 'vault' rather than accessing stored reserves
- Crawford reveals that NSAIDs like ibuprofen taken around ovulation can prevent follicles from rupturing and releasing eggs, effectively blocking ovulation despite normal hormonal changes
- Crawford presents data showing cannabis use can decrease eggs retrieved by 25%, reduce fertilization rates by 28%, and significantly impact sperm quality, making it one of the most concerning factors she sees in clinical practice
- Crawford describes fertility as a health marker, explaining that infertility correlates with increased rates of metabolic syndrome, cancer, heart attack, stroke, and early death due to underlying chronic inflammation

Transcript
[0:00] Everybody should get an AMH test. I think it's a very important marker. If you are listening to this and you want kids one day, ask your doctor for this test. It is not a test of egg quality. And we talked about what egg quality is, right? Genetics and egg competency, but it is a ch of how many eggs you have. And that knowledge can be really impactful for how you view your future and your plan. >> Welcome to the Hubberman Lab podcast, where we discuss science and science-based tools for everyday life. [0:31] I'm Andrew Huberman and I'm a professor of neurobiology and opthalmology at Stamford School of Medicine. My guest today is Dr. Natalie…

Essentials: The Science of Learning & Speaking Languages | Dr. Eddie Chang
Dr. Eddie Chang, a neurosurgeon and neuroscientist, discusses the distinction between speech and language, the neurobiology behind speech production, and his groundbreaking brain-machine interface work enabling paralyzed patients to communicate. He also addresses stuttering, neural augmentation ethics, and the future of avatar-based communication.
How to Overcome Social Anxiety | Dr. Nick Epley
Dr. Nick Epley, a behavioral scientist at the University of Chicago, discusses the science of social connection with Andrew Huberman, revealing that people systematically underestimate how positively strangers will respond to them. The conversation covers anthropomorphism, the benefits of everyday micro-interactions, social anxiety treatment through exposure therapy, and Epley's personal experience adopting a daughter with Down syndrome. Epley argues that small, habitual social connections throughout daily life are foundational to mental and physical well-being.
Understanding & Controlling Aggression | Huberman Lab Essentials
Andrew Huberman explains the neuroscience of aggression, focusing on the ventromedial hypothalamus and its estrogen-receptor neurons as the primary biological driver. He debunks the myth that testosterone directly causes aggression, revealing it is actually testosterone converted to estrogen via aromatization that triggers aggressive behavior. He also outlines practical tools—including sunlight exposure, sauna use, and ashwagandha supplementation—to modulate cortisol and reduce aggressive tendencies.
Master Self Control & Overcome Procrastination | Dr. Kentaro Fujita
Dr. Kentaro Fujita, a psychology professor at Ohio State University, discusses the science of self-control, motivation, and procrastination with Andrew Huberman. The conversation covers the marshmallow experiment and its criticisms, the difference between willpower and self-control strategies, and practical tools for overcoming temptation. Key themes include the role of 'why' thinking versus 'how' thinking, abstinence vs. moderation, intrinsic vs. extrinsic motivation, and the importance of psychological distance in self-regulation.
Essentials: Compulsive Behaviors & Deep Brain Stimulation | Dr. Casey Halpern
Dr. Casey Halpern, a neurosurgeon specializing in deep brain stimulation at Penn Medicine, discusses OCD, compulsive behaviors, and the brain circuits underlying urges and cravings. He explains current surgical and non-invasive treatments, the role of the nucleus accumbens in reward and compulsion, and the future of AI and machine learning in detecting and treating psychiatric disorders.
