A 30-year-old woman who has won the right to be sterilised on the NHS following a four-year battle has defended her choice - saying she was 'so sure' she didn't want to have children.

Holly Brockwell, 30, from London, appeared on This Morning today to tell how she had been told she could have the procedure to block her fallopian tubes following a lengthy battle to prove that she never wants to become a mother.

The technology journalist had asked for the procedure every day since she was 26 but doctors refused because of her age, offering to give her boyfriend a vasectomy instead.

Technology journalist Holly, 30, from London, has insisted since the age of 26 that she never wants babies, but doctors were reluctant to sterilise her because of her age. She has now been told that she is on the waiting list

After several attempts to get a referral from her GP, Holly learnt last week that she had finally been put on the list for the operation, which will take place in the next few months.

Appearing on the ITV show today, Holly - who revealed she had been trolled online over her decision - explained that she was 'so sure' that she didn't want children, she didn't even want to entertain the possibility of falling pregnant.

She said: 'At this point in my life I've worried enough about (getting pregnant) that I don't really want to have that. I just don't want that stress anymore. It's put me through so much emotional and psychological stress, I just want to close the door on it.'

Ruth Langsford and co-host Rylan Clark asked why the NHS should pay for her 'lifestyle choice'.

And Holly hit back with: 'It's going to save the NHS money, it's actually cheaper than contraception and cheaper than treating the side effects.

'It's cheaper than actually having a child on the NHS, it's cheaper than having IVF and all sorts of other things that the NHS offers.'

She added: 'In the long term it will save them money. The "lifestyle choice" argument is a silly one to me, because having children is a lifestyle choice. Both should be equally respected, surely? Why is one more OK than the other?'

Holly and her boyfriend, Zack, who was offered a vasectomy by doctors trying to dissuade Holly from having the procedure herself. Her wishes have finally been answered as she has been told she will be sterilised

Holly said: 'Every year for the last four years my GP has refused my decision. I couldn't even get a referral. The response was always: "You’re far too young to take such a drastic decision"'

But her argument was met with widespread disbelief by This Morning viewers. Elisha Joán called Holly's decision 'ridiculous', blasting: 'Your opinions change as you get older... Awful that it's allowed to happen.'

Maria Chatterton wrote: 'I don't agree with being sterilised young. I'm 37 and the nhs won't give me ivf. As my hubby has kids already.'

Gemma wrote: 'I know I don't want kids either but I personally wouldn't get sterilised.' A fellow viewer commented that Holly's decision was a 'bit weird'.

'How upsetting!' wrote Sammy Hancock. 'I can't have kids due to PCOS and this lady thinks she can b sterilised on the NHS!'

Holly spoke to hosts Rylan and Ruth Langsford of her happiness after doctors finally agreed to put her on the waiting list after a lengthy four-year battle, saying the fear of falling pregnant had caused her 'stress'

Writing in the Telegraph last week, Holly said: 'It's something I've wanted for years, but that doesn't mean it was an easy decision to make. It’s one I’ve researched, considered, weighed-up and defended, over and over again.

'Every year for the last four years my GP has refused my decision. I couldn't even get a referral. The response was always: "You’re far too young to take such a drastic decision."'

Holly first appeared on This Morning last year, in a segment entitled 'Why can't I be sterilised at 29?' Speaking to Eamonn Holmes and Ruth Langsford, she explained: 'This is something I've always felt and it's something I feel so strongly about, that I'm as certain as I could possibly be.'

When asked why she wasn't simply content with using birth control, Holly replied: 'Believe me, over the years I have tried every kind of pill available.

Appearing on This Morning today, Holly said: 'At this point in my life I've worried enough about (getting pregnant) that I don't really want to have that. I just don't want that stress anymore'

'The only ones that work for me are the really high dose ones, which are quite risky in terms of blood clots and things like that. They also make me very ill.'

Holly has written extensively about her process with the healthcare system which has led to widespread online abuse - evidence of which she showed to her doctor, and which and believes may have helped sway their decision to refer her.

Writing in the Daily Mail last year, she said: 'I accept hormonal contraception works brilliantly for some people, but while it’s kept me from becoming pregnant — which I absolutely don’t want — it’s also saddled me with dizziness, vomiting, skin problems, pain and relentless bleeding.'

She added that she did not want to have to rely on condoms and be faced needing to get an abortion, nor did she want a 'painfully inserted coil' sitting in her womb for years.

One doctor suggested instead that her boyfriend Zack should have a vasectomy instead - a more-easily reversed method of sterilisation, and another said they wouldn't consider the procedure until she'd had children.

After recently appearing on the BBC, Holly spoke of being targeted online by people who claimed they were 'happy she hadn't reproduced, that they're pleased there won't be any more people like me on the planet.'

On Twitter, Holly regularly shares the abusive comments with her 21,000 followers. Many suggest that she has been pursuing the operation for journalistic exposure.

Female sterilisation involves the fallopian tubes being sealed off so a woman's eggs cannot travel down to be fertilised.
