When Hillary Frank created The Longest Shortest Time in 2010, nuanced and inclusive discussions of parenting could be hard to come by. Her podcast filled that gap, beckoning to anyone who is a parent, has a parent, might want to be a parent, or simply shares in universal curiosities about how kids grow up. Last year, Frank handed the reins to a new host, Andrea Silenzi, who brought a different perspective to the show as someone who doesn’t have children but wants them. In the “Sperm Series,” she contemplates how, if she decided to become a parent on her own, she might go about procuring sperm—a process that, as it turns out, is not dissimilar from dating online. Her story is told with humor and a feminist sensibility, and the intimate topics it addresses—partners, fertility, the desire to be a parent—bring out a unique kind of vulnerability.
