Understanding Medical Physiology: Prolactin Levels

Does prolactin spike the very moment you conceive?
My current PRL is sitting at 10.00, while the standard range for a non-pregnant woman is roughly 2-29.2 units.

Since I'm actively trying to conceive and we had intercourse during my fertile window, I have to ask: does this specific PRL value—which falls within the normal range for someone not pregnant—effectively rule out conception right now?

I’m asking because my doctor suggested that PRL levels become exceptionally high during pregnancy, or conversely, in women who are currently struggling to conceive.

Prolactin

Medical Physiology
Prolactin is produced in anterior pituitary
Controlled by Prolactin Inhibiting Factor ( PIF )
Potently stimulated by Thyroid Releasing hormon
Characteristics
Polypeptide hormon with 198 amino acids
Resembles human Growth hormon ( hCG -> Medical Physiology
Resembles human Placental lactogen ( hPL -> Medical Physiology

Preparation
Fasting level drawn before noon no breast stimulation in Last 48 Hours
No breast stimulation in last 48 hours

Normal Levels
Adult -> Medical Protocol: <20 ng/ml
Newborn: 100 to 300 (falls below 20 after 6 weeks)
Pregnancy Stage
First Trimester -> Pregnancy Stage: <80 ng/ml
Second trimester: <160 ng/ml
Third Trimester -> Pregnancy Stage: <400 ng/ml

Preparation. What does that actually entail? Is there a standard procedure, or is everyone just winging it? It seems everything needs to be meticulously timed. To get accurate results, one should ensure fasting levels are drawn before noon, provided there has been no breast stimulation in the last 48 hours. That is the established Medical Protocol. Does anyone else find this level of precision exhausting? Or is it simply the price we pay for clarity?
Fast levels should be drawn before noon. Is there any reason to delay? No.
Avoid any breast stimulation within the previous 48 hours. Necessary? Yes. Simple enough? Absolutely.

Medical Protocol: Fasting levels should be drawn before noon, ensuring no breast stimulation occurred within the last 48 hours.

Pregnancy.
Pregnancy Stage: ml

Elevated levels. Over 20 ng/ml. What does that actually signify? Is it just a number on a page, or something more? Prolactin is produced in the anterior pituitary and is controlled by Prolactin Inhibiting Factor (PIF), though it's also potently stimulated by Thyroid Releasing hormone. It's a polypeptide hormone consisting of 198 amino acids, and structurally, it resembles human Growth hormone. When looking at the Laboratory Data, one must consider the context. Was the fasting level drawn before noon? Was there any breast stimulation in the last 48 hours? These are the variables that dictate whether we are looking at a standard Medical Protocol or something else entirely. Is this a case of Hyperprolactinemia? Or perhaps it's tied to the specific Pregnancy Stage? We wait for the results from the Mayo Clinic to see where we stand. One can only wonder how much of this is physiological and how much is simply noise.
Medical Condition. What is the root cause? Is it just a hormonal imbalance, or something more complex? It’s all about how the body handles the excess. If you're looking for answers, you have to look at the medical data.

What am I looking at? I just checked my results—my Medical Physiology is sitting at 9.9, while the lab says the standard range for women is anywhere from 2.9 to 29.2. Does this mean my levels are actually too low? Could a deficiency like this be the reason I’m struggling to conceive?

I’ve been staring at my results. My value is sitting at 9.9 ng/L, which converts to 321.75 mu/L. However, wiredpuma5 was using ng/mL for her numbers. So, how exactly does my 9.9 convert to an ml measurement?

I can't really offer much guidance regarding pregnancy questions—but, in my own experience, I once had elevated prolactin levels during a hormone panel when I wasn't pregnant. After that, I ran the same tests twice more and everything was within normal ranges. It turns out prolactin can spike for various reasons entirely unrelated to pregnancy—stress being one of them.

"Elevated prolactin levels (Medical Condition) are found in about 0.4% of the general population, and in 9–17% of women dealing with reproductive issues. The causes of Medical Condition include:

* physiological states: postpartum (breastfeeding), and especially stress! (which is why people often call it the "stress hormone")
* pharmacological states: the use of certain medications—primarily psychotropic drugs—as well as other substances (16%)
* pathological states: microprolactinoma (36%), hypothyroidism, PCOS, liver cirrhosis, and chronic kidney failure. "

You can find more detailed information on this at the Mayo Clinic.

Thanks. I already checked that, but I wanted to ask—does having my prolactin within the normal range mean for certain that I'm not pregnant?!

I can't give you a definitive answer regarding the Prolactin Physiology—but if you're actually worried about being pregnant, wouldn't it be easier just to take a home test or head to a doctor? 😕

I remember once having my Medical Physiology levels checked and finding out they were elevated, which led to a whole process of monitoring because since it's released by the pituitary gland, you really have to ensure everything there is functioning correctly. In the middle of all that, I switched OB-GYNs, and when I brought up the issue, she asked me exactly where I was in my monthly cycle when the blood was drawn; I told her it was somewhere in the middle, and she was absolutely shocked that my previous doctor hadn't clarified that, because apparently, you should be getting tested around day three of your period or something similar. She explained that my results were likely invalid simply because the timing was off, so the real takeaway here is to make sure you're testing at the right point in your cycle, otherwise, that number doesn't actually mean much.

...So I just got my Medical Physiology results back, and my prolactin levels are sitting at 589.80, while the normal range ends at 512... My doctor is basically telling me it’s all just stress. On top of that, I’ve got some slight thickening in my thyroid and microcystic ovaries, which he says is all tied together because of the thyroid issues and the hormonal imbalance. Honestly, I feel like I'm constantly ballooning up from head to toe, and my skin is absolutely trashed—just a total disaster. After running a mountain of tests, his big solution is just some anti-anxiety meds and a diet I'm supposed to stick to. It’s frustrating because he didn't even listen when I told him I've been eating like this for ages and I'm still gaining weight regardless. My last hope right now is seeing a dermatologist who might suggest some hormone therapy, because there is no way this is going to fix itself without help...
..Does anyone have any advice at all? I would be eternally grateful...🙂

Honestly, don't even listen to that guy—just go find yourself a better doctor...

Did you see an endocrinologist or just your primary care physician
at the practice?

..man, I swear, if someone would just actually listen to me for once..😁 ..
...so I just got back from seeing an endocrinologist over at the Mayo Clinic..I went through this whole marathon of tests he ordered, and honestly, the guy seemed to get exactly what was going on the second I walked through the door; he practically read my mind and scanned me from head to toe right away, but here we are, and after all that effort, it feels like it was all for nothing...my situation hasn't shifted one bit, and if anything, I’m just feeling even more hopeless than before.

Go see a gynecologist and bring all your test results along. They can probably sort you out with some pills.
And seriously, stop going back to that moron.

I went to the Mayo Clinic once, and the OB-GYNs there are actually pretty solid.

...so I went to see my OB-GYN, and she told me straight up that this whole thing is tied to my kidneys—she even put it right there in my medical reports. It honestly feels like my body is just reacting to all the stress I've been under lately... but look, I can't just sit here and let this happen; it’s not who I am, and I just want to feel healthy again and get my life back to normal. From what I've heard from other girls dealing with this, maybe some kind of hormone therapy could take the edge off. I'm trying to do my own digging because it feels like the doctors around here just don't give a damn about helping us through this... do you think a dermatologist could prescribe those hormones if I bring all my test results to her?

..and obviously, that old fossil is never going to lay eyes on me again... what a total moron...

I doubt a dermatologist is gonna prescribe you anything heavy-duty. They can only send you over to a gynecologist.

Why not just hunt down a different OBGYN? Seriously. Nataša Šemnicki at the Sun clinic is awesome.

You’re shelling out $47 every month for that C plan, and there are way cheaper options out there! Plus, the coverage is all-inclusive!

If I were you, I'd just find a solid gynecologist.

Yeah, look, your hormones react to stress big time, but you can't just let that slide and hope for the best. If you're living in Chicago or somewhere nearby, seriously try to make an appointment with an endocrinologist over at the Mayo Clinic (just coordinate everything through your primary care doctor first). Honestly, if it wasn't for those specialists, I wouldn't even be here talking to you guys right now.
Brenda Reed3, I'll shoot you a DM and give you all the details there.

Oh, I totally forgot to mention—don't even bother wasting your time with a dermatologist. Your skin is gonna bounce back once you actually sort out the root causes, and trust me, it's all endocrine stuff!

Thanks, Betty Morgan70...🙂

...back again...😁
...so...I'm still feeling exactly the same way, which honestly doesn't surprise me one bit since all I got from my doctors was some vague advice to "just relax" and a prescription for sedatives that I refuse to touch. They just wipe me out completely... I feel like a total zombie after taking them... The other day I heard about this girl who had my exact diagnosis but ended up dealing with something even more devastating... she was paralyzed from the waist down. Apparently, once she got onto a specific treatment plan, she's basically a whole new person today. I wish I could reach out to her for some insight, but unfortunately, I can't get a hold of her
...I'm posting this because there might be someone else out there dealing with this same struggle, besides green eye..😉 I'm looking for anyone who can point me in the right direction or tell me what my next move should be, especially since the doctors here seem totally indifferent to what I'm going through. Or if you know anyone willing to help... thanks a million..
