Having no trouble naturally conceiving her first three children with partners in her previous relationships, Brooke felt she could easily get pregnant and opted against going through an IVF clinic to get sperm.
The 30-year-old says that this way, she could have more autonomy — as well as avoiding the costs and counselling required if going through a clinic.

Brooke spoke with about 15 men from the Australia-based Facebook group when she was in the process of choosing a donor.
They drew up a contract, largely to stipulate that the baby was solely hers.
I wanted [a donor] that was doing it out of the goodness of their heart, not to get something in return.

“I personally don’t feel like they’re doing it for the right reasons if they’re just offering natural [insemination].”
Some health and legal experts have raised concerns about this growing practice — including the regulation of these online spaces, adequate legislation being in place, potential for people feeling pressured into natural insemination, and transparency surrounding how many families a donor has given their sperm to.
Wanting to use the same sperm donor
“There would have been no reason to use a clinic if we weren’t looking to have the same biological father for our children,” Anastasia told Insight.
‘Everything that we told our children was a lie’
Anastasia and Lexie’s third son also had serious medical conditions like his older brother.

Wanting to alert other families who may have used the same donor of potential health complications, the couple decided to DNA-test their children.
They are still in legal negotiations with the Queensland clinic three years on, and the clinic involved maintains that the correct donor was used.
Preventative measures
There is also an electronic witnessing system called RI Witness that detects and monitors all activity in an IVF laboratory, to further mitigate the risk of human error when it comes to moving samples around.
The decision to donate sperm
“It’s just something that at the age of 26, 27, I just hadn’t fully anticipated.”

The 57-year-old Melbourne dad says that he didn’t consider at the time the impact that donating his sperm could have on his relatives and own future children.
“They’re just lovely people. It’s been a great experience.”
‘The state registers don’t communicate with each other’
“A lot of it is really about identity checking at the IVF clinic. But that also comes with trust — and whether the donor will express that they have already donated with another clinic.”

Jefford also believes there needs to be more regulation of sperm and egg donations at a national level.
“But I do think that we can put in place rules around people finding each other through social media; and people being educated and aware about what it means to find a donor.”
