The responsibilities of raising a family can deter many women from continuing their careers in TV - though an obsession with beauty remains.
As I prepare to leave the political beat to move abroad, I thought I'd dedicate my last ITV News blog to the issue of women in Westminster.
Attacks against women continue to rise across Pakistan. Unlicensed acid is easily available, and perpetrators are treated too leniently.
New figures released Labour reveal that only 7% of the total TV workforce (on and off-screen) are women over the age of 50.
Meanwhile, the majority of TV presenters who are over 50 are men (82%).
Miriam O'Reilly, who won an employment tribunal against the BBC on the grounds of ageism, said:
These figures raise the obvious questions of where have all the older women gone and why did they go? Was it their choice to leave their jobs or was it a decision forced upon them?
The broadcasters say they are committed to the fair representation of older women, but the figures don't bear that out.
I'd like to know the reasons why so many talented women have disappeared, while their male counterparts have grown older and still have their jobs.
Women on television are affected by a "combination of ageism and sexism" that does not apply to men, according to new figures released by Labour.
Harriet Harman, shadow secretary of state for culture, media and sport, asked the six main UK broadcasters how many older women they employ on screen and behind the camera.
The findings were that while the majority of over 50s in the UK are women (53.1%), the overwhelming majority of TV presenters who are over 50 are men (82%).
It was discovered that only 7% of the total TV workforce (on and off-screen) are women over the age of 50.
Ms Harman said: "The figures provided by broadcasters show clearly that once female presenters hit 50, their days on-screen are numbered.
"It is an encouraging first step that broadcasters have been open in providing these statistics. Their response shows that they all recognise that this is an important issue that needs to be addressed.
"I will be publishing these figures annually so we are able to monitor progress."
Ms Harman will also be holding a roundtable with broadcasters in the House of Commons today to challenge them to take action.
Former Desperate Housewives' actress Eva Longoria has spoken about her wishes for women on International Women's Day and "every day of their lives".
John Lennon's widow and peace activist Yoko Ono has tweeted:
A global day to call for the education of all girls and women is to be held in honour of Malala Yousafzai, the Pakistani schoolgirl shot by the Taliban, it has been announced.
Her father Ziauddin and former prime minister Gordon Brown outlined plans for Malala Day as they appeared at the Women of the World Festival at London's Southbank Centre on International Women's Day.
Mr Brown said the issue of universal education for girls was in desperate need of a "liberation movement and a freedom fight for change".
Malala Day will be held on the girl's 16th birthday, July 12, and will be celebrated with a youth assembly at the United Nations in New York.It is hoped that young people from around the world will mark the day, aimed at providing education for the 32 million girls who do not currently have access.
Singers and musicians from around the world have come together for "One Woman", a song launched today to mark International Women's Day.
The song written for UN Women is a call for listeners to join the drive for women's rights and gender equality.
