Women who freeze their eggs should be allowed to keep them for longer than 10 years, fertility experts are telling the government.
Legislation says frozen eggs must be destroyed after this time, unless a medical condition has left the woman prematurely infertile.
Experts told the Victoria Derbyshire programme that the limit was arbitrary and had not kept up with technology.
The government has said an extension "would be a significant policy change".
Campaigners say the method of freezing has changed since the law was created, and the current method, vitrification, means eggs can be frozen without deterioration for an indeterminate period of time.
They say the limit means a growing number of women face losing their chance of having a baby, or rushing to find a sperm donor so they can re-freeze an embryo.
Sarah Norcross, director of the Progress Educational Trust, which helps people with infertility issues, is one of the three experts due to meet junior health minister Jackie Doyle-Price on Monday.
"There's absolutely no biological reason for this law," she said. "It's discriminatory against women and removing an option for them to take charge of their reproductive system.
"If you want to freeze your eggs in your late 20s, you might not then have decided you want to use them by your late 30s."
