Egg Freezing Laws in Europe: Where, When, and How Long

Last updated: February 2026

Social egg freezing is legal in most of Western Europe. Austria banned it until October 2025, when its Constitutional Court struck the ban down as a violation of the right to private life. Norway still restricts it to medical reasons. France covers the procedure for women aged 29-37, the first country in the world to partially reimburse non-medical egg freezing.

The storage rules are where it gets interesting. The UK lets you keep frozen eggs for 55 years. Denmark makes you use or discard them by age 46. Greece abolished its 20-year ceiling in 2022. How long your eggs stay viable is a matter of physics. How long you’re allowed to keep them is a matter of which parliament got to the question first.

Austria’s Constitutional Court Ruling

On 6 October 2025 (Case G 52/2025), the Austrian Constitutional Court ruled that Section 2b, paragraph 1 of the Fortpflanzungsmedizingesetz (FMedG), which restricted egg retrieval to cases where “a physical ailment or its treatment creates a serious risk that pregnancy can no longer be achieved through sexual intercourse,” is unconstitutional.

The Court’s reasoning: the desire to have a child is part of private life and a fundamental right under Article 8(1) ECHR. The blanket ban is “disproportionate.” The argument that social egg freezing creates pressure on women to delay motherhood was considered but rejected as insufficient justification (The International; Haslinger/Nagele).

The repeal takes effect 1 April 2027 to give the legislature time to adopt a new regulatory framework. A related case (G 145/2025) challenges whether restricting assisted reproduction to women in relationships discriminates against single women (Kinderwunsch Dr. Loimer).

Greece: Law 4958/2022

Greece’s 2022 reform was the most significant change to egg freezing law in Europe that year. Law 4958/2022:

• Legalized social egg freezing (previously medical reasons only)
• Abolished the 20-year cryopreservation ceiling; storage now runs in 5-year renewable periods with new consent
• Removed the requirement for spousal consent to freeze eggs
• Allows divorced women to use previously frozen oocytes without their ex-husband’s consent
• Established a cryopreservation bank for HIV-positive individuals

Storage Time Limits

The UK’s jump from 10 to 55 years in 2022 was the biggest single change. Before, women who froze eggs at 30 had to use them by 40 or lose them. Now they have until 85. The old 10-year limit created an absurd situation: women froze eggs to buy time but were then pressured by an arbitrary clock. The new 55-year limit effectively removes the constraint for any practical purpose.

Costs

France is an outlier: the 2021 bioethics law made France the first country in the world to partially reimburse social egg freezing through the national health system, covering the harvesting procedure for women aged 29-37. Storage costs remain out of pocket (France24).

The UK is by far the most expensive market, with total costs of £7,000-8,000 compared to €2,100-2,400 in Czech Republic or Spain. For patients willing to travel, the procedure in Prague costs less than the medication alone in London.

When to Freeze: What the Data Says

ESHRE’s analysis of optimal timing for elective egg freezing (PMC, Mesen et al., 2015):

Oocytes needed for a 70% probability of at least one live birth:

Before age 35, freezing at least 24 oocytes gives up to a 90% chance of a live birth. After 38, the chances of success drop considerably and the number of oocytes retrieved per cycle is lower, meaning more cycles to bank enough eggs.

ESHRE’s position: although freezing is best when younger than 35, there should be no age cutoff for the freezing itself. The use of frozen eggs should be limited to age 50.

The most cost-effective age to freeze: 37. This is the point where the benefit over no action is largest relative to cost (PMC).

ASRM’s 2023 Ethics Committee opinion supports planned oocyte cryopreservation as ethically permissible (ASRM).

The numbers are clear. The earlier you freeze, the fewer eggs you need. The gap between freezing at 34 and 40 is not marginal: it’s 10 eggs vs 35. That’s potentially 3 extra retrieval cycles, which at €2,000-3,000 each adds €6,000-9,000 to the total cost plus the physical burden. The irony is that women who feel most urgently that they need to freeze their eggs are the ones for whom the procedure works least well.
