A medical procedure that has been used to freeze a woman’s ovaries is being offered for the first time as a way to delay menopause.
This procedure, called "ovarian tissue cryopreservation,"isn’t something new. It was developed back in the late 90s and is commonly performed to preserve the ovaries of girls and young women undergoing tissue-damaging cancer treatment. Doctors take out parts of the ovaries and freeze them before such patients undergo chemotherapy and radiation treatment. In the future, if these patients want to have children, doctors reimplant the ovarian tissue in the body.
But now, the U.K.-based company, ProFam, is offering the same procedure for women up to the age of 40 who just want to delay menopause─the time when levels of reproductive hormones fall, and a woman stops getting her menstrual period.
