A ground-breaking study from Stellenbosch University (SU) has revealed promising advancements in male contraception, with a focus on a safer, reversible and non-hormonal solution. Kyla Raoult, who recently earned her master’s degree in Polymer Science from SU, has developed an innovative on-demand hydrogel contraceptive; the hydrogel, water-absorbing material, forms a semi-permeable barrier within the vas deferens, effectively blocking sperm while allowing seminal fluid to pass.

Unlike traditional vasectomy procedures, this method is reversible; the gel can be dissolved and flushed out using a simple solution, restoring fertility without permanent alterations. Raoult’s work addresses a significant gap in male contraceptive options, which are currently limited to condoms, vasectomies, and experimental hormone-based methods, each with limitations or side effects
