This groundbreaking performance offers a rare opportunity to contribute to and witness queer family-making. Embark on a journey with performance artist Krishna Istha as they search for the ‘perfect’ sperm donor.  The show will explore human connection and parenthood, and challenge expectations, redefining what it means to create a family as a transgender person.  

In the World Premiere of this one-of-a-kind durational experience, First Trimester invites you to witness intimate live interviews between Krishna and 100s of participants over two weeks, in a quest to find them and their partner a sperm donor, or at least discover the qualities that bring them closer to their perfect match.

Krishna asks questions that range from funny to serious, from matter-of-fact information to philosophical perspectives in order to make the ultimate connection.

Audience members are invited to watch as the interviews unfold, but are also welcome to sign-up as a participant and prospective donor, regardless of their ability to donate sperm. We welcome participants aged 18 to 60+ from all backgrounds. Each interview is pivotal in helping Krishna inch closer to finding the right donor. 

This is a durational performance. For weekday performances you can choose to stay for the full 3 hours. For Saturday performances you can either buy a ticket for the full 8 hours (plus a 1 hour break) or for 2 hour slots. You are welcome to come and go as you please with the slot you have selected.
