Hi, thanks for using healthcare magic
I am sorry for your loss.
PCOS is a common cause of infertility
. It is diagnosed if two of the following are present; (1) irregular or delayed periods (2) cysts in the ovaries seen on ultrasound
(3) signs and symptoms or blood tests indicating high levels of male hormones (androgens
It is treated with lifestyle changes to reduce weight , if weight is an issue, metformin
and medication to help with the release of an ovum or egg from the ovaries.
IN terms of the ultrasound, pelvic ultrasounds would look at the structure of the uterus , tubes and ovaries. It would also look at the thickness of the lining of the uterus. It is possible that the 4mm refers to the thickness of the lining of the uterus but it would be difficult to say without the ultrasound report.
The thickness varies but increases during pregnancy
I hope this helps
