Background

Prolactin (PRL), also known as lactotropin, is a protein best known for its role in enabling mammals to produce milk. Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and nursing. It is secreted heavily in pulses in between these events. Prolactin plays an essential role in metabolism, regulation of the immune system and pancreatic development. Prolactin levels may be checked as part of a sex hormone workup, as elevated prolactin secretion can suppress the secretion of follicle stimulating hormone and gonadotropin-releasing hormone, leading to hypogonadism and sometimes causing erectile dysfunction. Prolactin levels may be of some use in distinguishing epileptic seizures from psychogenic non-epileptic seizures. The serum prolactin level usually rises following an epileptic seizure.

Nice shoes!
Size: 11, Color: Black Full Grain
I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
