Thyroid Issues Affect Female Fertility
Normal thyroid function is really quite importantfor reproduction. When your abnormal function is at the level of being either hipo or hyperthyroidit can have gross effects on your menstrual cycles make you either not ovulate all ovulatevery irregularly. It can also lead to increases in endometrial lining beyond what you wouldnormally see as a result there would be very heavy menstrual periods. There are avariety of symptoms that are naturally related to reproduction, that are tied to thyroidabnormalities. Correcting the thyroid problem will ultimately correct those abnormalities.It's going to be indirectly tied in other ways because the changes in metabolism (eitherextreme weight loss or are weight gains) can
affect reproduction in other ways and throughother mechanisms. More importantly normal thyroid function is very much related to anormal pregnancy and there can be fetal effects if a woman goes through her pregnancy withunder active thyroid. So when we replace thyroid we'd rather see it a little bit on the hyperside rather than on the under active side. If we are going to prepare, it's going tobe to increase the function a little bit more because that helps to protect the baby. Onceone becomes pregnant if the woman is hypothyroid (underactive thyroid) and she's taking thyroidreplacement the thyroid doses may need to be increased during the pregnancy becausethe natural changes in hormones during pregnancy
will increase the need for more thyroid hormone.
