Infertility isn't only a women's issue, though too often, it's talked about like it is. In this episode, we're digging into male factor infertility: what it means, how it's diagnosed, and how it impacts couples emotionally, physically, and relationally.

We're joined by Paul Kassebaum, a quantum physicist, and his wife Julia Cohen, an economist, who live in Westchester, NY. In 2021, their family-building journey took an unexpected turn with a diagnosis of male factor infertility. They open up about the medical and emotional twists and turns of their path, and why they hope sharing their story will help others feel less alone.

To give us a full picture, we also bring in experts: Dr. Ariel Moradzadeh, a reproductive endocrinologist, and Abbe Golding, a genetic counselor at Jscreen. Together, we explore:

• What male factor infertility actually is, what the causes are, and how it's evaluated

• Who should be doing the testing and why it matters

• The role genetics can play in male infertility

• The emotional and psychosocial impact on men and couples

• How couples like Paul and Julia navigate the unexpected and find resilience

Whether you're directly facing male factor infertility, supporting a partner, or simply learning more about the different paths to parenthood, this conversation is a mix of story, science, and support.

Note: This episode is the 3rd of a series of 5 that we are collaborating on with Jscreen in 2025.
