Prolactin - Hyperprolactinemia - Dopamine, TRH - Pathophysiology

Prolactin (PRL), Dopamine, TRH & Hyperprolactinemia | Pathophysiology | Endocrine Physiology.
Prolactin is a hormone secreted by the anterior pituitary gland. It aids in lactation (breastfeeding) by stimulating the production of milk from the mammary glands in the breast…In addition to prolactin, other hormones that affect the mammary glands include estrogen (increase size and fat deposition), progesterone (to make the acini/ alveoli), and oxytocin (for milk ejection or let down). Prolactin uses the JAK-STAT pathway of cell signaling (biosignaling).

Dude who are you! The world needs to preserve you, your brain! What an amount of information lying around in this video. Huge thanks to you! Your parents grew you in a great manners. They should be proud of themselves for such a creation! Thanks a lot, for your works to this human mankind!

[@MedicosisPerfectionalis]

I appreciate you so much!

​@@MedicosisPerfectionalis I have hyperprolactinoma, adhd, low testosterone. have an MRI on 8th April for finding it out whether secondary/tertiary hypogonadism. I just saw the first 3 minutes which all play a role in making prolactin (no other youtube channel said with this clarity), and went to search for TRH possibilities to test in a blood test, which is time consuming and not essential, it seems. Now I have to rely only on an MRI. Thanks for the video!

Fascinating, prolactin and dopamine are very prominent in Ray Peat's writings.

[@Criss9931]

Hi medicosis, I'm a fan of your teaching.I hope you will increase the duration of your subscription or reduce the price per month. I know you work a lot for the content but as an Indian lower middle class family it's just too much for me

Thanks for these informations❤

[@MedicosisPerfectionalis]

My pleasure!

[@sarahzoubair8895]

Hello, Quick question , why isn’t the PRH ( prolactine releasing hormone ) the one responsible for releasing prolactine ? Thank you for the video ❤

[@hindali157]

Thanks❤❤

[@plummetplum]

Wow this is complex stuff.

[@rramachandran873]

Doctor, can increased prolactin cause galactorrhoea even in a setting of a hypogonadism where in the alveoli of the breast are underdeveloped?

[@MedicosisPerfectionalis]

It becomes less likely to take place!

[@Harzli.feriel]

please I have a question related to oestrogen and progesteron ,it is mentionned in our book that oestrogen stimulate prolactin secretion,while the progesteron inhibits it, is it true? beecause u said in the video that oestrogen not only block the activity of prolactin but also inhibits it's secretion please

[@MedicosisPerfectionalis]

It depends on the "time". Refer to Guyton and Boron's Textbooks.

[@user-jhsoshxhs33]

When Estrogen acts like it stimulate prolactin ?
