Mum Wants To Freeze Her Eggs For Infertile 2-Year-Old Daughter

Penny Jarvis with 2-year old daughter, Mackenzie
A mum-of-five plans to freeze her eggs to enable her infertile two-year-old daughter to have children - effectively her own brothers and sisters - later in life.

Penny Jarvis, 25, wants to undergo the procedure so her daughter Mackenzie will be able to use the eggs for an IVF pregnancy when she is older.

Two-year-old Mackenzie has Turners Syndrome, a chromosomal abnormality, and was born without ovaries. She is also partially deaf, and has speech problems.

If she were to use her mother's eggs, the resulting baby would be her half brother or sister, and the biological child of its grandmother.

Miss Jarvis defended her plans. Speaking to the Daily Mail from her home in Sheffield, she said:
'You could look at it as her giving birth to her own brother or sister, but I choose not to see it like that. You do the best for your children and Mackenzie's daughter or son would be her own. It's a comfort to know that if she did have a child they would still have part of her own genetic make-up as well, so it would still be a part of her. Hopefully, it won't just be me doing it. I'd like to think her three sisters would offer their eggs too. But if they didn't, at least the option would be there for her.A few people have told me they think it's a bit sick, but on the whole people have been supportive.'

Miss Jarvis and her partner Karl Stephens, 42, are full-time carers for Mackenzie. Their other children are Morgan, six, twins William and Abigail, three, and five-month-old Jaymie-Leigh.

Miss Jarvis has set up a Facebook group for parents of children with Turner Syndrome and has said most of its members are supportive of her decision:

'The people that I speak to on there have all told me they think it's a great idea. Most people realise that I just want to do what is best for my child.'

'As soon as I found out that Mackenzie would be infertile, I discussed it with her dad and my family and friends and everyone has said they will support me.'
