Hi girls 🙋 I was reading that a cis-girls body starts to release progesterone at tanner stage 3 breast development.  Which helps with milk duct growth and firmness.
My endo upped my estrogen last month and have move from stage 2 to 3 now, (maybe 3 1/2). I'm wondering if progesterone is something I need.  I know this is controversial, but what would it hurt?
Smiles, Jessica 🙅‍♀️

I have been taking it up until recently.  I'm not really sure it's has any effect at all.  I stopped a couple of weeks ago and am going to see what happens between now and my next appointment in March.  I have been reading about some negative effects related to exercise performance and improvement also and since that's one of my focuses right now it's worth it to me to see what effect stopping has on my body.

My Dr. is also skeptical about its usefulness but let's me take it if I want.

I've heard it can make you moody, to either extreme and helps with libido.
Have you had anything like that happen Deborah?

Many women on the Forum reckon it is wonderful.

My endo advised against it but I took it anyway. It made me feel awful as far as mood and had little physical effect. Maybe that's just me.

I don't think it has made me moody or had any bad effects psychologically but my mood before HRT was so bad that I don't think anything could have made that worse.  My libido has also been nearly non-existent.  Last year my Dr. cut my progesterone in half and I didn't notice any differences before or after that change.

What I have read is that it can interfere in exercise recovery because of the way it binds to testosterone receptors.  Since I have stopped it my recovery does seem to be a little better but so far the difference there is subtle and may be due to other factors or even to my imagination.

I have read a lot on it on several websites and have read similar that it helps breast development. I also read that most doctors prefer not put you on progesterone. I took it for a while I think it did jumpstart my breast development I believe. It didn't affect my mood but, it make me feel not that great, as opposed to just estrogen. So I think there are some positive effects that help transgenders but, I prefer not taking it. I have heard a lot of us that do take it and like what it does for them. So I would say try it out and see if you like it, after you convince your doctor probably. Happy transitioning !

I have been on it for two weeks and cannot say I have yet to see any change in any department. I'll stick it out for 90 days then decide what to do. I am switching to injections for estradiol next week as the number of pills I'm taking daily is *insane* to me (8 + vitamins). My breast growth seems to be in a nonexistent phase though the dysphoria is also pretty low right now. Not sure if they are related.

I also have massive cravings for carbs the last few months since my estradiol dose last increased and have gained 20lb as a result, and my self control has gone flying out the window. The dr was concerned the progesterone would make the cravings worse, but that has not appeared to have happened.

I'm at 15 months on hrt and been on progesterone since 9 months.  Breasts started to become  rounder and firmer and heavier within 2 months of starting progesterone.  I take micronized progesterone, the generic for prometrium.  I take it daily for 3 weeks then off for 1 week.  It's not to imitate a menstrual cycle, per se, but when I am on it for too long without a break it starts to feel a bit cloying and excessive.  I tired a 2 week on 2 week off cycle but after a week without it I get some serious moodswings.

Cis girls begin producing progesterone at menstration. This happens in a natural cycle. Estrogen climbs then progesterone climbs behind it. The two hormones are naturally paired and required for the reproductive system to work. Progesterone in a cis girl is needed for the endometrial tissues to reach the state that pregnacy can occur.

Progesterone levels drop off in cis women as they age in comparison to estrogen levels. This leads to what is called estrogen dominance and can have symptoms such as pseudo-hypothyroidism.

Why we should all have progesterone bioidenticle only

Yes progesterone is involved with fully maturing the breast tissues. It works with HGH and two other growth factors within the breasts. It helps to round out the breast tissues.

Progesterone helps block estrogen's negative effect on thyroid regulation. (Stops pseudo-hypothyroidism)

The metabolites of progesterone reduce the blood clotting factor increase caused by estrogen. Reduces or negates the increased risk for DVT.

Progesterone is one of the main building blocks of allopregnalone, an important neurotransmitter. The hypothalamus can make a tiny amount but having blood circulating levels can reduce depression for most. Note though that depression can have a multitude of causes. Others can be the signal hormones in the brain such as Sertraline.

I have stopped it altogether. I find that it just makes gain so much weight and it also makes my skin so oily and I feel the anti estrogenic effect of P in my system.

It's just not a good feeling.

Thanks Josie 🙋 this is good information to discuss with my endo.  She might say it's too soon, and I'll listen to her, but I'd like to eventually try.

Has this actually been consistently observed in ciswomen?

QuoteThis leads to what is called estrogen dominance and can have symptoms such as pseudo-hypothyroidism.

If so, are we certain this is the CAUSE of the hypothyroidism or could it be caused by other changes taking place at the same time?

QuoteProgesterone helps block estrogen's negative effect on thyroid regulation

Estrogen, especially orally and in higher doses/levels non-orally, tends to increase TBG (thyroid binding globulin) and as a result more thyroid hormones are bound BUT the thyroid gland receiving less of it or less negative feedback, increases its production of thyroid hormones and as a result, the free concentration of thyroid hormones remains unchanged.

I've been taking it for about six months.

I don't really notice any changes to mood, weight, or skin.  Unfortunately I don't see any increase in nipple development.  I'll probably stop soon.

Kay progesterone levels do drop lower earlier in cis women. Check every study and charting of progesterone to estrogen blood levels. This also explains why the older a cis woman gets the less likelihood of pregnacy as lower progesterone levels mean slower second stage endometrial growth that is needed for an embryo to implant.

The term pseudo hypothyroidism is applied to estrogen interference thyroid regulation. Wether that is the official term or not it is known that hypothyroidism can be caused due to estrogen's effect and that progesterone or its metabolites reduce the effect estrogen has on the thyroid regulation. Most doctors treating it only monitor TSH levels and assume that a prescription of levothyroxin is the cure. In many cases in women (who have a higher rate of hypothyroidism then men ) hormone imbalance can be the trigger mechanism. Treating the symtom of high stimulating hormone and not checking for possible causes is common practice.

Perhaps the dose is too low for you. Orally, much of it is eliminated, more so in certain people than others. Something to look into with your doctor.

Ok. Need to look into it.

From personal experience and from speaking to a dozen of transsexual women, I can attest that estrogen did NOT affect my or their thyroid hormones in the least bit, despite taking only estrogen, sometimes at very high doses, for several years. We need to see studies where the addition of progesterone reverses hypothyroidism and where a clear cause and effect can be established between estrogen and thyroid problems. Until then, I remain VERY skeptical.

Estrogen dominance seems to be more hearsay than actual science, as far as I can tell with the exception being uterine stimulation where unopposed estrogen can increase the risk of profuse bleeding and uterine/endometrial cancer.

Hi Jessica;
I n Australia Prometrium became available off the shelf from Pharmacies about 4 months ago and a month ago my Doctor agreed for me to trial it for 3 months. I am just  starting on month number 2. So far all I have had is positive benefits:
1. I am losing weight. I have already had to make two extra holes in a belt I use as my waist slims down. Basically my constant need to eat has left me. When my doctor doubled my Oestrogen about 9 months I was for ever hungry.
2. My nails are much stronger and are growing again. Previously they broke very easily (after my Oestrogen was doubled).
3. I am sleeping very soundly - I take my Prometrium capsule last thing at night with a Hot milk drink just after taking my second dose of my Oestrogen (Progynova).
4. I am not moody at all, despite others saying I will feel it.
5. I have some upper pole roundness appearing on both breasts and the result is I am now getting some cleavage.
6. My skin is incredibly super soft. This is especially so on my buttocks and lower abdomen
7. 8 weeks ago I had a full body wax and still have had little or no hair re-growth. Mind you that might be from the Oestrogen as it has steadily been getting finer.

However I have felt that despite all the above it a little cloying, but my pharmacist said I should trial it for 3 months and then move to a 2 weeks Oestrogen only and 2 week Oestrogen & Progesterone regime, similar cis females, then if necessary to a 3/1 week regime if I am finding 2/2 to much to take.
I will let you know progress.

With my doctor's permission, I'm doing a little experiment to try and mimic more closely ciwomen as far as progesterone goes so instead of taking it orally, where allopregnanolone (and other neurosteroid/metabolites levels) exceed far too much progesterone levels, I open the capsule and apply the white substance inside on my vulva so that progesterone is directly absorbed through the skin (in that area, it absorbs more efficiently than regular skin). 

I'm personally not convinced progesterone is needed in us but if my doctor agrees, then why not? Just to see what happens

Results so far:
- sleepy, tired, a little out of it and LAZY
- headaches
- lower abdominal cramps
- hot flashes
- breasts a little sore
- appetite is slightly up
- a little bloated
- skin softer and glows more, similar to T (testosterone) effect but less pronounced
- hair less oily (I take T post-op).

So, mostly negative for now. Not sure I want to go on.

Thank you Judith!  There are so many conflicting theories.  I do appreciate some real life experiences.  It does seem to work for some women and not for others.  I'm going to ask my endo next appointment.
My body hair has thinned substantially and it would be nice if progesterone helped that even more. 
Have you noticed any change in your libido?
Hugs, Jessica 💁‍♀️

Hi girls 🙋‍♀️ I found this link to a good read about this.  It gives one study's conclusions, along with arguments contrary to it.  It seems a bit biased, but somewhat credible.

Interesting study on mice **lacking** progesterone receptors:

The Journal of Steroid Biochemistry and Molecular Biology
Volume 56, Issues 1–6, January 1996, Pages 67-77

"an inability to ovulate, uterine hyperplasia and inflammation, severely limited mammary gland development and an impairment in the induction of a sexual behavioral response."

Progesterone seems therefore to play an important role in sexuality and breast development, according to this study, at the very least, in mice.
