High-Powered Exec Sues Fertility Clinic Over Devastating Stroke

In November 2025, a high-powered executive is fighting for compensation from a prestigious fertility clinic, claiming its intensive "IVF bootcamp" treatment led to her suffering a devastating stroke. Navkiran Dhillon-Byrne, 51, began private IVF treatment at the Assisted Reproduction and Gynaecology Centre (ARGC) in London in 2018 after being denied NHS funding.

Four years after being told the NHS could not fund her fertility treatment, Ms. Dhillon-Byrne underwent IVF at the ARGC clinic in April 2018. However, just 10 days after her treatment finished, she suffered a stroke which her lawyers say has left her with ongoing vision problems. As part of her IVF cycle, Ms. Dhillon-Byrne had also agreed to undergo a pioneering IVIg immunotherapy treatment, which she is now suing the clinic and its director Dr. Mohamed Taranissi over, claiming they failed to adequately warn her of the stroke risks.

The clinic denies any wrongdoing, insisting Ms. Dhillon-Byrne was fully informed of the risks. But she maintains the clinic overestimated her chances of success and failed to secure her "informed consent" before treatment. Her lawyers argue the offering of IVIg was "unethical" without strong evidence of its benefits and clear warnings about the risks. If successful, Ms. Dhillon-Byrne's multimillion-pound claim is likely to have a major impact on the fertility treatment industry.
