A review to examine pregnancy and maternity discrimination in the workplace has been launched by the Equality and Human Rights Commission (EHRC), which said bias against pregnant women or those returning to work after maternity leave "needs to be tackled".
EHRC head Mark Hammond said it is "very concerning" that women in modern society are discriminated against at work because they choose to have children.
Experts will investigate employers' practices towards workers who are pregnant or on maternity leave, and these employees' experiences.
Arresting images of teenage boys appearing to be pregnant are at the centre of a new campaign to encourage young people to practice safe sex in the US city of Chicago.
The city has among the highest teenage pregnancy rates in the US, so health campaigners decided to take a radical approach to combating the problem.
The images - which feature doctored images of heavily-pregnant boys in different settings - will go on display on billboards across Chicago.
Brian Richardson, a spokesman for the Chicago Department of Health, said he hoped the campaign would "cut through the clutter and get people thinking about teen pregnancy and teen births, and how it can affect more than just teen girls".
Advice from the Royal College of Obstetricians and Gynaecologists (RCOG) has provoked concern, with critics saying the report is alarmist and can add to a mother's stress.
Tracey Brown, from Sense About Science, said the warning could cause more harm than good.
Pregnancy is a time when people spend a lot of time and money trying to work out which advice to follow, and which products to buy or avoid. The simple question parents want answered during pregnancy is, 'Should we be worried?'.
What we need is help in navigating these debates about chemicals and pregnancy. Disappointingly, the RCOG report has ducked this.
As the report itself shows, there are many unfounded rumours about links between particular substances and pregnancy outcomes.
Pregnant women are being advised to avoid chemicals in household products such as food packaging, cosmetics and family medicines that could cause harm to their unborn babies.
The Royal College of Obstetricians and Gynaecologists says women should be made aware of the sources of chemicals to minimise the possibility of harm during pregnancy.
It has urged them to "play it safe", despite uncertainty about chemicals' effects and the surrounding risks.
But the report's authors admit there is little evidence to suggest whether such chemicals do affect a baby's development, or even if there is a risk to health. However, they advise women to assume that a risk is present.
