FIRST ON 7: More Melbourne women freezing eggs

Melbourne women worried about missing out on motherhood are taking matters into their own hands.

An increasing number are deciding to have their eggs frozen, to guarantee the chance of a family whatever their age.

Single and 35, Amber Pritchard's biological clock is ticking.

Just being with other mothers with their babies makes her clucky.

“It definitely tugs at something, I do want to have a child, I do want a family," Ms Pritchard said.

Her yearning to become a mother prompted Amber to attend an egg-freezing seminar run by Melbourne IVF, attended by over 100 women.

Women heard their fertility drops significantly in the mid 30's, and by the early 40's chances of falling pregnant are dramatically lower.

Ms Pritchard told 7 News: "Rather than stressing that I have to have a child in the next one or two years, I think it would give me an extra three to four years hopefully.”

Reasons for not starting a family include not having a partner, or delaying childbirth because of travel or career opportunities.

Hundreds of women have already chosen egg freezing as there own type of fertility insurance, but experts warn there are still no guarantees they will result in a healthy baby.

Professor Stern said: "For every 10 eggs that are frozen, only one or two will make good quality embryos."

Kylie Berger took her fertility into her own hands using a donor sperm, she's expecting her baby in January.

At 35 she couldn’t wait any longer for Mr Right.

Ms Berger said: “That can happen at any time and it doesn’t matter how old you are when you get married, but the time can come where its not possible to have children anymore."

Kylie has three other embryos frozen, possible siblings for her first child.

Fertility experts recommend women that their late 20's is the best time to fall pregnant with a partner the old fashioned way.

“I think there's a reason why we call it the old fashioned way, and that’s because it just doesn’t happen like that any more," Ms Pritchard.
