But this happened around the same time that she fell pregnant with an IVF embryo from another couple as part of a surrogacy arrangement. Sign up for the Health newsletter Thank you! The rare case is believed to be a first in Australia. The woman gave birth to a boy, who was hers, and a girl – the other couple’s – and the children have been raised separately since then over the past 10 months. According to reports, there has been no dispute over parenthood, but the case was heard in the children’s court of Queensland this week due to technicalities with surrogacy laws. The state’s laws set out that the separation of “birth siblings” is banned. Because of this, the couple whose IVF embryo was carried under a surrogacy agreement had to seek a parentage order for custody of their son. Luckily, this was not opposed by the woman who gave birth. Most read in Health The court’s final ruling in this “unique” case stated that while the children were “gestational twins”, they were not birth siblings for the purpose of surrogacy laws. According to a report in The Guardian, the woman who carried the babies entered into an “altruistic” surrogacy arrangement with the other couple after being connected by mutual friends. This couple had been unable to conceive naturally as the woman was born without a uterus. The woman who carried the babies – who was already a mum to five kids – agreed to surrogacy and had an embryo inserted via IVF in April 2025. About two weeks later, however, an ultrasound revealed that she was carrying two foetuses. Subsequent testing revealed that the boy was the biological child of the woman carrying the pregnancies and the girl was the other couple’s – the IVF embryo.

Eggs are fertilised with sperm in a laboratory and the embryo is placed in your womb (uterus). Your chance of having a baby using IVF can depend on many factors such as: what’s causing your fertility problems your age your body mass index (BMI) lifestyle factors, such as smoking or drinking alcohol A GP or the fertility clinic team can discuss this with you before starting IVF. If you’re aged 39 or under, you may be eligible for 3 full cycles of IVF on the NHS if either of these apply: you’ve been trying to get pregnant through regular sex without using contraception for at least 2 years you’ve tried 12 cycles of artificial insemination and at least 6 of those cycles used a method called intrauterine insemination (IUI) However, if tests show that you’re unlikely to get pregnant without IVF, you should be referred for treatment immediately. If you’re aged 40 to 42, you may be eligible for 1 full cycle of IVF if all of these apply: you’ve been trying to get pregnant through regular sex without using contraception for at least 2 years you’ve tried 12 cycles of artificial insemination and at least 6 of those cycles used a method called intrauterine insemination (IUI) you have not had IVF before You’ll also need some tests to check that your ovaries will respond normally to fertility medicine. Source: NHS The boy was “conceived separately to the… embryo implantation process, and without medical assistance”, reports said. The court heard that the couple had not intended to conceive their own child at that time. But it was stressed that this is not to suggest their child is “anything other than loved and wanted”. Due to the complexities of the laws surrounding surrogacy in Queensland, the couples hired an independent counsellor earlier this year to help with the situation. Both families told the counsellor they intended for the children to grow up knowing each other. They will be raised with “an age-appropriate understanding of their place within the wider family network”, the court heard. The judgement said: “The parties also demonstrated a shared understanding that openness and honesty regarding [the girl’s] origins and parentage will be in her best interests over time.” Comment now
