For decades, fertility discussions placed the diagnostic burden almost entirely on women. When Gilbert and Harries struggled to conceive naturally in their late thirties and early forties, they initially assumed Harries would carry the clinical focus. Comprehensive testing revealed the opposite: the primary barrier was severe male-factor infertility.
Tests showed that Gilbert possessed an exceptionally low sperm count combined with compromised motility. Medical specialists discovered that the vast majority of his sperm cells were either non-viable or unable to travel effectively to fertilize an egg. Gilbert later described learning that his sperm was essentially "swimming in circles," a realization that hit him with profound guilt and shame.
In response, the couple made the calculated choice to film their experience for the 2021 BBC broadcast Stand Up to Infertility. The documentary documented the profound imbalance common to male infertility: while the underlying condition lay with Gilbert, Harries had to endure the invasive, physically punishing brunt of the intervention, including hormone injections, egg retrievals, and repeated clinical protocols. The film exposed how few resources, support networks, or honest dialogues exist for men facing reproductive failure, sparking widespread conversation across the UK medical community.
