Progerterone and the IUD

I started to use the Morena IUD 3 years ago. It is good for 5 years. The first 2 1/2 years I did not have a period. I had my hormones checked 1 1/2 years ago and discovered I had Hypothyroid disease and low progesterone and Testosterone levels.

I am treating with Levothyroxin for the thyroid and natural Projest caplets and Test cream. I am on 300 mc of Prog daily and 1/8 tsp of test 3% cream daily. I started the hormones in June of 2009. Started getting my period in January of 2010. I have had the Mirena checked and it is still in place and fine. I now have regular periods and with heavy bleeding and cramps. Up until July of 2010 they were between 24-28 day cycle. In the beginning of August I had a period after only 11 days. Could the hormones be making this happen? I have had my levels checked and they are fine. I had my annual exam and it was normal. I don't want to stop the hormones. Maybe it is the Mirena. What do you think?

Progerterone and the IUD
by: Wray

Hi there The Mirena leaks a progestin into the body, this lowers progesterone levels, as it stops ovarian function. It would also lower your testosterone for the same reason. I'm not in favour of any synthetic contraceptive. The safest is the copper T IUD, it leaks no progestin into the system. Please see our web page on Contraceptives for more info. When you say you are taking progesterone caplets, is this actual progesterone or herbs to help? If herbs they are not going to raise progesterone levels, if oral progesterone that's not going to help much either, although 300mg is a high dose. If in fact it is mg, as you put 300 mc, which means nothing to me. Please see our page on Progesterone application methods for more info on delivery systems. The amount of testosterone you are getting seems extraordinarily high. 1/8th tsp of a 3% cream means you are getting 18.75mg testosterone, normally women are given 0.3 to 0.5mg. It's difficult to know how to advise you, as I don't know enough to help. Take care Wray
