Spawning Season: A Microbiologist's Quest for Fatherhood

Anchored by a poignant account of his efforts to become a father, Spawning Season by Joseph Osmundson — a microbiologist and NYU professor — is a wide-ranging meditation on what it means to be biologically "fit" in Western society today. Named to The New Yorker's Best Books of 2026, this memoir is instantly recognizable to anyone whose dreams of having a child have been dashed or deferred.

The Biology of Desire

Osmundson identifies the "fitness paradox" — the gap between our universal instinct to reproduce and the structural, economic, and biological barriers that stand in the way. Though his specific barriers are queer identity and the prohibitive cost of surrogacy and adoption, his emotional journey resonates far beyond. A secondary narrative following salmon on their journey to reproduce in warming waters proves surprisingly apposite, underscoring what is uniquely human about Osmundson's dilemma: that, for us, a universal instinct can also be a question.
