Testosterone is one of those seemingly buzzy topics that a lot of people have started talking about in recent years, but there’s a valid reason for that buzz. Josh Whalen, 44, co-founder and CEO of Conquer, experienced that reality firsthand when he discovered his testosterone levels had dropped low enough to trigger a wide range of debilitating symptoms.

Conquer, the precision health platform focused on hormone optimization and personalized care, has announced a strategic combination with Gina Bartasi and her company YourJOY.ai to add fertility to its existing hormonal health platform. Bartasi will join as founding partner and CEO of the fertility division.

When Josh Whalen‘s once athletic, rugby-playing physique morphed into a heftier “dad bod,” he figured it was just the reality of getting older. That’s how he dismissed other symptoms, too. His sex drive plummeted and he felt super tired — but working as a entrepreneur in his mid-30s, he attributed his problems to the mounting pressures of work and parenting two kids. And he wasn’t motivated to do anything about it.
