Testosterone levels in 40-year-old men are 30 percent lower than their fathers, and most doctors still have no idea what to do about it. -Watch this episode on YouTube for the full video experience: https://www.youtube.com/@DaveAspreyBPR Host Dave Asprey sits down with Dr. Justin Houman, a nationally recognized urologist and Assistant Professor of Urology at Cedars-Sinai Medical Center. Fellowship-trained and specializing in men's health, male fertility, and sexual medicine, Dr. Houman combines cutting-edge medical advancements with holistic lifestyle strategies to help men optimize testosterone, sexual health, and reproductive performance at every age. Together, Dave and Dr. Houman tear through the myths, the bad science, and the outdated medical dogma around testosterone, erectile function, fertility, and male sexual health. They cover everything from why testosterone levels have collapsed in a single generation, to the real story behind the FDA black box warning, to practical protocols for men who want to optimize without sacrificing fertility. This is the masterclass on men's health that no one else is having on record. This is essential listening for anyone serious about biohacking, longevity, human performance, hormone optimization, brain optimization, anti-aging, functional medicine, mitochondria, and Smarter Not Harder approaches to male health. You'll Learn: Why testosterone levels in 40-year-old men are 30 percent lower than their fathers and what is driving the collapse How low testosterone connects to anxiety, depression, high cholesterol, blood sugar dysregulation, and all-cause mortality risk The truth about the original testosterone and heart attack study and why it still has not been retracted How to preserve fertility while on TRT using Clomid, enclomiphene, and HCG Why daily low-dose Cialis is one of the cheapest and most effective longevity drugs available What shockwave therapy, PRP, exosomes, and Botox injections actually do for erectile function How red light therapy at 660 and 850 nanometers supports testosterone production and nocturnal erections The supplement stack including ashwagandha, tongkat ali, fadogia agrestis, and creatine that supports healthy hormone levels Why porn-induced ED is epidemic in young men and how to reverse it How PT-141 and peptides fit into a complete male optimization protocol Thank you to our sponsors!

Excellent points on the veganism debate. I only wish vegans were open to facts when discussing these things.
Hey Dave. Tell Tracy that his book is probably being shadow banned in Amazon. When you search for, it auto corrects to "Tracy Chapin" every time so it not something random. It shows something completly unrelated. Maybe his lawyers should look into this.

great podcast, thank you very much 😄
In the development of cybersecurity of satellite European systems, an important stage is regularly tested https://orbitaltoday.com/2023/04/26/satellite-hackers-seize-control-of-esa-satellite/ What disadvantages in modern satellites can be useful to spies and enemy hackers?
If you are looking to burn calories then less time equals less calories. So if that's your goal then this wouldn't be beneficial, correct?
Hi Dave, You mentioned in this podcast that you do NOT recommend psyllium as prebiotic fiber - at the same time on other podcasts you're promoting uprisingfood.com which has psyllium as one of their main ingredients. I'm a bit confused. Could you please help me to clarify this? Should I avoid uprisingfood.com products as they have psyllium in it? Thx.
I'm just wondering: if the infrared sauna heats the person up from the inside: 1. Then Why does a "cabin" needed to be built around it, why cannot it be just a wall panel, like the JOOVV 3.0 Red Light Therapy devices? 2. And if the "cabin" is indeed needless for the infrared Sauna, then why JOOVV or SUNLIGHTEN - or any other similar company don't build a device /wall panel which offers 2 in 1: both Red Light Therapy AND infrared sauna in one single device / single session? Would this be too difficult/expensive to build? Or would there be health risks to have infrared sauna and red light therapy session together, at the same time?
re: low T as a function of training intensity and recovery Highly recommend mark sisson's book primal endurance. Brad Kearns case presented in that book is right in line with this guy's experience.
watch soft white underbelly. tell them and the host of that show what you said in the peer's podcast about therapy. give them money to better their lives since you don't think they need some help. really disappointed in you Dave. you let me down. I will no longer praise you.
what you said about the therapy is so wrong and proves you are an not really a sufferer like you say. I followed you for years...years... not now. you have no idea what me and others have been through. You were fat and picked on, but what about a full trauma childhood, leaving you really mentally crippled. I liked you but now not so sure. you think anyone that had a awful upbringing or horrible experience can do it themselves. slight insult.
what you just said about the therapy is so wrong and proves you are an idiot. I followed you for yers...years... I am out. you have no idea what me and others have been through. wow. you are not in touch. thank you for showing me what type of person you are. I liked you but now no. you think anyone that had a awful upbringing or horrible experience can eR a carrot or spend your kind of money sitting in a tube of water and they get better. shame on you. someone last week said terrible things about you but I defended you but now what you Saud in the episode is an total insult.
really enjoyed this one. it continues to amaze me how otherwise intelligent well-informed people like the guest can remain so ignorant about this virus and the vaccine. I.e I e. overestimating the risk and uninformed about how useless and dangerous the vax has proven to be. not to mention completely uninformed about a middle or alternate path to addressing the public health issue. heaven forbid public health officials should encourage testing for vitamin d, inflammation and blood sugar regulation. or that they would advocate supplementation and holistic approaches to preparing oneself to win against the virus. heaven forbid they should advocate prophylactic treatment for those at high risk of exposure or infection. no way should this intelligent individual advocate for prophylactic use of proven effective early treatments
this is the first time someone has explained why memory palaces are useful in our day and age. time to clean off the vines.
