The Mirena will result in slight bleeding or spotting for the first few weeks but I found after that it was very little trouble. Unlike the old fashioned coils, it releases a low dose of progesterone locally thereby keeps the womb lining thin and, for me, stopped cramping etc.
Re: hair loss. when on synthetic progesterones, did you just get hair loss or did you also get more hair growth elsewhere. If there is a true androgenic effect then one usually gets more hair growth around genitals, nipples, legs, arms etc.
When I tried Tibolone, the androgenic effect made hairs grow around my nipples, pubic hair got thicker and I broke out in spots. I'm wondering if your hair loss thing could be other factors - have you had your thyroid function tested recently? The hairless could be more to do with thyroid!!??
The US MM site gives different info for HRT types and I don't know whether it includes this rather useful info on the different types of progesterone:
Testosterone derived - Norgestrel, Norethisterone acetate and Levonorgestrel.
Less testosterone related - Medroxyprogesterone acetate(MPA).
Least testosterone related - Dydrogesterone and Micronised progesterone (Utrogestan).
I wondered if you had tried Medroxyprogestone (MPA) or Dydrogesterone?
Also: Here is the UK info on the Mirena:
MIRENA
Mirena is a levonorgestrel (type of progestogen) releasing system which sits inside the womb, gradually releasing the progestogen into the womb. It is licensed in the UK and Ireland as a contraceptive agent, for treatment of heavy periods and, from August 2004, also for the progestogen component of HRT. It can be used in both the perimenopause and postmenopause and it is particularly useful for:
Persistent progestogenic side effects from systemic HRT despite changes in type and route of progestogen.
When contraception is required along with HRT in the perimenopause.
When withdrawal bleeds on sequential HRT are heavy, after investigation if indicated. (see WHEN TO BE REFERRED )
With Mirena in place, systemic estrogen alone can be taken as the Mirena provides adequate protection of the womb lining and the estrogen dose and route can be tailored to meet the individual's needs.
Progestogenic absorption throughout the body is minimal so reducing progestogenic side effects. The effect of Mirena on the womb lining can significantly reduce bleeding and when used as part of an HRT regimen, in time, 30 to 60% of women have no bleeding at all. Although Mirena used for contraception is licensed for 5 years, the license for use for the progestogen part of HRT is currently 4 years.
