A woman who wants to conceive a child using donor sperm has launched a court challenge to existing laws that bar her from accessing IVF without her estranged husband's consent.

The Victorian woman, known to the court as “LR”, says she is being discriminated against on the basis of her marital status.

The woman is still legally married, but separated and estranged from her husband, the Federal Court in Melbourne heard on Thursday.

She intends to divorce him when the 12-month waiting period is over, and wants to undergo in-vitro fertilisation to become pregnant, using her own eggs and donor sperm.
