21 progesterone blood test...

I had this blood test a few months back and my GP told my that my level was normal at 32 but that anything under 28 was bad. Now I'm not expert but it's got me thinking.... Is 32 still really low? Is this why I can't get pregnant. I've read other posts of people having levels of 70-100. I have normal monthly cycles and it doesn't suggest anovulation and I don't have any fertility issues myself (my partner does).

Has anyone else had this test? Does anyone have knowledge with this please? When I Google it, it comes up with medical talk that I don't understand.

Thanks for the reply. Guess I'm just clutching at straws why it's not happening for me. Never once been pregnant

Have you and your partner had other tests done?

My partner had VR which although successful, his motility is still fairly poor. I've had loads of tests. Zero wrong with me apparently. My AMH is high (no underlying cause), my FSH is really good. No cysts, polyps, no endometriosis or pcos.

Hello. I would say 32 is fine. I’ve had progesterone tests when on clomid come back at 80 and still not pregnant. I have now found out that my husbands morphology is only 1% and motility wasn’t great so this is why. I would say it’s probably more likely you’re struggling due to the VR. They may suggest IVF ICSI eventually. Sorry not trying to scare you, just what I’ve found out on this journey !

Hi Jessy I know it’s easier said than done but please try to stay positive! You’ve got 2 more days and you’ll find out.

My husband has motility and morphology issues with his sperm as well. Our first cycle of ICSI failed and it was a crushing heart break but we have nothing frozen so will have to endure that whole process again. I’m praying you guys are in the clear and Friday brings you a big massive pregnancy!

Sending lots of love ❤️

I’m confused about the progesterone issue. I’ve read that progesterone levels vary wildly over a ninety minute period. You could test at 5, and then at 40 an hour later. And then there’s day to day fluctuations as well as cycle to cycle. If this is true I’m not sure how useful progesterone testing is at all. It seems standard in America to stop testing progesterone at all after a heartbeat is seen because it is such an unreliable indicator.

Yep I just checked. Progesterone during the luteal phase is released in pulses, and no measurement is reliable because the amount is constantly changing. It may be a test of common concern, but it may be that too much emphasis has been put on progesterone tests and fertility.

If one has a luteal phase defect whereas the corpus luteum is not producing sufficient progesterone, I believe it is inferred from the short luteal phase, and not by any number. I do believe that supplementing progesterone, most reasonably if a person does have a LPD, is an excellent idea, until the placenta is developed enough around ten or twelve weeks to produce sufficient progesterone. By then then Corpus Luteum would have ceased to function at all.
