Not only is the Perth nine-month-old an IVF success story, but the opening of a new Northern-based clinic could mean she may eventually get a younger sibling.

TasIVF announced this week that it would open a clinic in Launceston by the end of October.

The clinic, to be located in QV Centre in High Street, will offer fertility assessments and treatments including ovulation induction, intrauterine insemination and simplified IVF.

Northern patients have to travel to Hobart at least once a month to receive treatment.

For Ivy's mum Ali Plunkett, the clinic will be helpful if she and her husband Rob decide they want a third child.

The couple had their first child Ryder, 5, naturally in September 2010.

"We knew that we didn't want just one child, but trying to have a second child didn't happen," Mrs Plunkett said.

"We had all the tests under the sun and it was really inconclusive as to why we couldn't fall the second time, so we did IVF."

Mr and Mrs Plunkett had consultation appointments in Launceston, but egg collection had to happen in Hobart.

It took 18 months, numerous Hobart trips and five cycles - two of which were cancelled - before Mrs Plunkett fell pregnant.

Ivy was finally born in January.

Mrs Plunkett said the family initially decided they wouldn't try for a third child because of the service's distance.

"But now [because of the new clinic] we may change our minds," Mrs Plunkett said.

"It is much easier if you don't have to go to Hobart, not that it is far, but logistically it was hard because Ryder always came down with us."

TasIVF medical director Bill Watkins said the number of women seeking fertility treatment in Tasmania had increased rapidly over the years.

Dr Watkins said when he moved to Tasmania in 1996, TasIVF did 150 egg collection cycles.

Last year, it did 700.

"Primarily the rise is because women are leaving their run of having children a little bit late," Dr Watkins said.

"From 25 onwards, your number of eggs start to decline.

"I always say to people, as soon as you think you want to have a baby, there is no better time."

Currently, one in 23 births in Tasmania is conceived using IVF - the highest rate in the country.

Dr Watkins said about 35 per cent of TasIVF patients are older than 40.

Thirty single mums and same-sex couples also use the service.

Dr Watkins said the new Launceston clinic would make IVF more accessible to Northern Tasmanians.

"It will be a simplified approach compared to what we have in Hobart," Dr Watkins said.

The clinic will also have lower out-of-pocket cost as simplified IVF, also known as low-stimulation IVF.

It is a lower cost treatment, which uses the same laboratory procedures as standard IVF, but employs a lower dose of medication to stimulate egg production.

The process produces fewer eggs than a standard IVF cycle, which are then collected under sedation instead of a full anaesthetic.

"We're hoping to have it a bit less than $1000," Dr Watkins said.

"More complex cases, people with medical issues or people who are significantly overweight will need to go down to Hobart, where they have the full hospital set-up.

"We're getting a lot of positive feedback."

Ten full-time staff are expected to be employed at the Launceston clinic once it is open.
