A new study has indicated that endometriosis, in which cells from the lining of the uterus grow in other regions such as fallopian tubes and ovaries, can also be quickly and accurately identified by a small test. Researchers led by Ian Fraser at the University of Sydney and Maomar al-Jefout of Mu’tah University found that a small tissue sample taken from the uterine lining with a device inserted through the vagina works just as well. This condition of the uterus, which is linked to infertility, painful periods and pain during sexual intercourse, until now could only be detected through surgery.
