Inconceivable combines memoir and investigative reporting to reveal an underground community of sperm donors and recipients who have chosen to circumvent traditional fertility avenues and meet up on their own terms. As an active participant in this community, Valerie Bauman uses her own story as a lens into this movement of people attempting to dodge the costly and often discriminatory world of sperm banks and fertility clinics. Inconceivable is a window into the unfair legal, financial, and medical entanglements that compel many single women and LGBTQ+ couples to take their fertility into their own hands.
