An Enlarged Ovary or Ovaries can be caused by one of several problems such as cystic or solid mass, polycystic ovarian syndrome, ovarian cancer, ovarian cyst, congenital problems, tubo-ovarian abscess, and metastatic malignancy.
So while the enlarged ovaries themselves may not be the problem, their underlying cause is what always requires attention.
Enlarged ovaries would generally manifest themselves with symptoms such as pain in the lower abdomen or back, and an irregular menstruation cycle.
It is important to distinguish enlarged ovaries from Polycystic Ovarian Syndrome, because though PCOS can cause the ovaries to be enlarged, that is not always the case. Even with PCOS the ovaries can sometimes remain more or less the same size; or not significantly enlarged.
The reason that enlarged ovaries could be a concern is that there are several serious problems that could be causing the ovaries to enlarge and as such should not be ignored.
Ovaries could be enlarged due to tumors, cysts or other problematic reasons. They could also be responsible for reduced fertility and if enlarged ovaries are detected they should not be ignored.
