Here is an extract below from an article I read in the Times last year, about a little known condition called Ashermanns Syndrome
THE HIDDEN THREAT TO FERTILITY
A rarely diagnosed condition called Ashermans causes miscarriage and can prevent pregnancy, yet its cheap to test for and can be treated
Catherine Bruton The Times Dec 10th 2007
Sarah Raynes had no trouble conceiving the first time around. But when, a year after her son was born, she wanted to try for her second child, her menstrual cycle hadnt resumed despite confirmation from a home ovulation kit that she was ovulating regularly. At her GPs advice, she gave up breast-feeding, but several months later there was still no sign of her periods returning, and Sarah started to get concerned.
She turned to the internet for advice: I typed ovulation without bleeding into a search engine and came across a condition called Ashermans Syndrome.
Also known as scarring of the uterus, this syndrome can result in permanent infertility and recurrent miscarriage. It is usually caused by a D&C (a dilation and curettage) procedure, performed to clear the uterus after a miscarriage, to remove a retained placenta after the birth of a child or, in a minority of cases, to abort a pregnancy.
