Story summary

McGill University researchers have developed a light-activated microneedle patch to automate hormone delivery for in vitro fertilization (IVF).
The patch uses nanoparticles to release leuprolide when activated by near-infrared light, reducing human error in hormone injections.
Researchers say the breakthrough could speed clinical adoption and help patients needing daily injections for diabetes or rheumatoid arthritis.
The demand for IVF is rising, with 42% of US adults familiar with fertility treatments.
