Показать описание
Hormones shape each and every one of us, affecting almost every aspect of our lives - our height, our weight, our appetites, how we grow and reproduce, and even how we behave and feel.

This documentary tells the wonderful and often weird story of how hormones were discovered.

Presenter John Wass, one the country's leading experts on hormones, relates some amazing stories - how as recently as the 19th century boys were castrated to keep their pure soprano voice, how juices were extracted from testicles in the hope they would rejuvenate old men and how true medical heroes like Frederick Banting discovered a way to make insulin, thus saving the lives of countless diabetes sufferers.

And hormones remain at the cutting edge of medicine as we try and deal with modern scourges like obesity.

Bloody fascinating! My husband screamed out with a severe headache & had stroke like symptoms 2.5yrs ago....we thought the worst! Turned out he had a congenital pituitary tumour that burst! Doctors decided to treat it by steroids & other tablets, other than an far it's PCOS unfortunately still leaves me infertile & it looks like I've gone into early menopause.... endocrinology sometimes works but it doesn't always! Great documentary however ❤️xxx

And don't forget the Gut's microbiome. The "whole" conversation is deeper than one gives credit.

Hormones always mesmerized me!
Some hormones cause you behave like an angel, some make you an evil.

Amazing and fascinating documentary, much better to watch something like this, presented by someone that is clearly in awe of the subject despite being a renowned professor on the subject. Not boring at all- should use it in high schools for biology lessons!!

I did my Music History term paper on Farinelli and other castrato. I got an A, but I'm sure my professor was a bit perplexed. I just thought his voice was so beautiful and the practice was intriguing. It was also very sad. It was outlawed, but continued for a while.

I love this documentary..it really fascinates me that every time that i watch it i am capable of understanding more..i never thought it would come a day that i would actually want to watch scientific documentaries

I just wanted to point out that as far as i am aware of the subject, the pacreantic ducts enters in the duodenum of the small intestine and not in the stomach

Feel free to correct me if i am wrong
😂 I don't hold grudges

I'm well aware of the fact that hormones can be seriously effected by medication and that can make you gain weight. It happened to me, and no matter how little I ate it made no difference. At the age of forty my weight went from 48kg to 101kg in a little over a year. It cost me my gallbladder and because of this I remained that weight for twenty years until it was finally put down to my thyroid. Because my gallbladder had been removed it seems I couldn't lose the weight after I'd been taken off the meds.

I truly believe junk food is messing up the hormone leptin resulting in so much obesity in society today. A very informative documentary. Thank you.

Lately, I speculate if my colorectal cancer had opportunity to flourish because of my hormones. I have done all genetic testing available, and despite being Ashkenazi Jew, I have no predisposition to have colorectal cancer at 28. Hormones are the most powerful forces inside my body, I feel.
