Behind the Hollywood charm, rugged action-hero persona, and demanding filming schedules, Josh Duhamel has always held a quiet devotion to one role above all others — that of a husband and father. And recently, the 52-year-old Transformers star surprised fans by revealing a deeply personal yet powerful step he took to preserve the vitality of his marriage with 31-year-old wife, Audra Mari.
In a candid interview with Men’s Health Lab, Duhamel opened up about his journey with testosterone replacement therapy (TRT), and how it’s played a key role in both his personal wellness and his relationship with Mari, whom he married in 2022.
Though Hollywood is no stranger to beauty regimens and age-defying secrets, Duhamel approached his decision with sincerity and vulnerability. “It’s important for her that I stay as young and virile for as long as I can,” he shared, referencing Mari, his wife of nearly three years and former Miss World America.
Rather than shy away from the taboo, Duhamel spoke openly about how the therapy not only strengthened his physical energy and intimacy but also gave him a renewed sense of purpose. “There is an overall wellness… just having that energy, that desire to go out and achieve — to be a better dad, a better brother, a better friend, a better business owner,” he said.
His openness struck a chord with many men who, like him, may have hesitated to ask questions about low testosterone or aging-related fatigue. “I didn’t want to talk about it, neither did anybody I was asking about it,” he admitted. But eventually, a personal check-in led him to explore the option seriously.
“I took a personal inventory of how I was feeling, and I knew that I wasn’t quite where I was five or ten years before. That’s when I got myself tested, and realized my levels were low,” he explained.
What sets Duhamel’s revelation apart is the way he frames it — not as a vanity-driven move or a quick fix, but as part of a broader commitment to his relationship. In a marriage with a significant age gap, Duhamel wants to ensure he can show up with the same energy and passion he had in his younger years. And not just for his wife, but for the life they’re building together.
The actor shares a son, Axl, 11, with his ex-wife, singer Fergie, and a second son, Shepherd, just 17 months old, with Mari. Between the demands of parenting, acting, producing, and public life, the desire to stay healthy and fully present isn’t just personal — it’s relational.
“You don’t taper off like you would normally,” Duhamel said. “And I think that’s one of the benefits of [testosterone therapy], mentally and physically.”
Long before his recent headlines, Duhamel has often expressed his love and admiration for Mari. He’s referred to her as his grounding force and someone who’s helped him stay focused on the things that matter. The couple tied the knot in an intimate ceremony in North Dakota, choosing meaningful simplicity over Hollywood extravagance.
While some may view their age difference with curiosity, Duhamel sees it through a different lens — one that values communication, health, and long-term connection. “She’s an amazing girl. She keeps me grounded. She keeps it real,” he told E! News shortly after their wedding.
And it’s not just about looks or staying young in a superficial sense. It’s about preserving the energy to love fully, give generously, and live intentionally — all things that Duhamel has quietly prioritized.
By speaking publicly about testosterone therapy, Duhamel is also helping break down outdated stigmas around men’s health, aging, and emotional transparency. In a society where many still expect men to “tough it out,” his honesty invites a healthier, more compassionate conversation.
It also reveals something more intimate about him — that behind the celebrity façade lies a man deeply invested in staying connected to his loved ones, growing alongside his wife, and embracing every chapter of his life with vitality and heart.
And this Father’s Day, as he celebrates surrounded by family at their cabin — his only request being time with his sons — Josh Duhamel reminds us that love, health, and commitment are the real secrets to a passionate marriage. Not fame. Not money. But the willingness to show up, stay curious, and grow old with purpose.
