prolactin levels

Hi Wray, I have a small prolactinoma, and have been using the progesterone cream to compensate for the low female hormones I have due to the prolactinoma.

I have been using it for two months and I just had my prolactin levels tested in blood.

Unfortunately they had gone up about 15%. I had hoped they would have been reduced.

Can you tell me why this is happening?

Thank you

Hi there I can't tell why, but suggest you read our page on Prolactin. Maybe you're not using enough progesterone, I also don't know what brand you're using, some don't absorb well. Take care Wray

Progesterone & prolactin levels

Hi Wray

It is Natpro progesterone cream Ive used. 1 tube over 2 months, calculated it must be around 30 mg pr day?

I know that it was the progesterone cream that made the prolactin levels go up, because I had a blodtest done right before starting using the cream, and it was the usual level that have been stabile for a year.

The question is why did the levels go up if progesterone normally should supress prolactin?

Is it because it stimulated estrogen?

Should I continue using the cream and hope it will become estrogen dominant with time?

Or is two month enough time to become estrogen dominant?

Hi there Yes the progesterone did stimulate oestrogen leading to Oestrogen Dominance. If you have a prolactinoma I suggest you use at least 200mg/day, not 30mg. This will only exacerbate things. Please read the prolactin page I gave you. Take care Wray
