Call for Tasmanian central sperm and egg donor register, for donor-conceived children's 'right to know'

Lottie Frohmader, 17, has always known she was conceived with sperm from a donor.

"I don't think there was a moment where Mum sat me down and said 'you're donor conceived', I just always knew," she said.

"Maybe I didn't understand the ins and outs of it, but I always knew I had a mum and didn't have a dad.

"I had a donor."

But while Ms Frohmader has always been completely comfortable and proud of her heritage, she said she has had a lingering curiosity about her biological father.
