Around 200 servicewomen have been reportedly sent back home to Britain after finding out they were pregnant.
The soldiers forced to return to the UK between January 2006 and December last year include 99 from Afghanistan and 102 from Iraq.
Critics have called for mandatory testing to avoid unnecessary medical emergencies because the medical facilities available there are very basic, Daily Star reports.
However, top brass fear pregnancy checks would be an 'invasion of privacy,' while a retired soldier and editor of Armed Forces Of The United Kingdom, Major Charles Heyman suggested that it would make a lot of sense if some sensible arrangement could be made for women before they travel to the front line.
A MoD spokesman said that the small numbers of personnel who discover they are pregnant on operations are returned at the first convenient opportunity.
