Couples facing fertility challenges. Male factors account for half.

Three drivers. All modifiable.

Men have no credible, integrated solution built for all three. Until now.


THE DAVREX SYSTEM

One system that addresses the three drivers simultaneously.

Davrex integrated system — thermoregulation wearable, Vitality AM and Recovery PM supplements, cooling therapy pods, Man Down Man Up guide, and Davrex app

The Davrex Thermoregulation Wearable

More sperm. Higher testosterone. All day, without thinking about it.


Designed to maintain optimal scrotal temperature during the hours you spend sitting. The only all-day device built for discreet wear during normal daily activity. Invisible, comfortable, and working while you are.

Vitality AM & Recovery PM

The right ingredients, taken when your body is actually primed to use them.


The first male fertility supplement system designed around your body's natural rhythms. The AM formula supports testosterone production and sperm development during your body's peak hormonal window. The PM formula supports overnight cellular repair. Backed by 48 randomized controlled trials.

Cooling Therapy Pods

Undo what hours of sitting does to your fertility and your testosterone.


Targeted precision cooling sessions to counteract cumulative heat exposure. 30 to 40 minutes, designed to fit within your daily routine.

Man Down, Man Up

The science of what is happening to male health, and exactly what to do about it. Written for the man who wants facts, not filler.


The complete guide to male reproductive and hormonal health. Written without clinical jargon, without agenda, and without the gaps a 10-minute appointment leaves behind.

Davrex App

Your compliance, your data, your clinical pathway. All in one place.


Monitor your progress and receive personalized insights from our guide when you need them. Built to make the system work harder the longer you use it.

Three pillars.One discipline.

Man using the Davrex system at home — three pillars of male reproductive health
01

Temperature


Your testicles need to stay cooler than the rest of your body to produce healthy sperm. Sitting for hours at a desk, in a car, or on a couch works directly against that. Reducing scrotal temperature by even one degree measurably improves sperm concentration and motility.

02

Biology


48 clinical trials across more than 4,000 men confirm that the right nutritional support taken consistently measurably improves sperm quality and the chances of conception. Every Davrex ingredient is drawn from that evidence base. Nothing is included without a reason. And nothing is taken without timing. The AM formula works with your morning hormonal peak. The PM formula supports overnight cellular repair.

03

Behavior


Up to half of all male fertility challenges come down to lifestyle, not genetics, not luck. Daily habits around sleep, stress, and movement compound over time. Man Down, Man Up and the Davrex app exist to make those habits automatic.
