[00:00:00]PCOS just got a new name. It's now called PMOS, which stands for polyendocrine metabolic ovarian syndrome. This change is years in the making, and it's largely because the condition, formerly polycystic ovary syndrome, was never really about the cysts. In fact, the name was kind of a misnomer. So, back in the 1930s, doctors treated POS by cutting a wedge-shaped piece out of a person's ovary. And weirdly, this worked. We still don't really know why. But anyways, when the scientists looked at these little wedge-shaped pieces, they saw fluid fil sacks and said, "Ah, cysts." But they weren't really cysts. True ovarian cysts are larger pockets of fluid that form without any function. These little cysts that the scientists were seeing back in the 1930s were actually underdeveloped follicles with eggs that had never been released. But the original name PCOS stuck, at least until this week. Here's where it gets really interesting. For a long time, doctors thought that PMOS was mainly about hormones, specifically high levels of sexual development androgens like testosterone. That's why women with PMOS often have symptoms like acne, irregular periods, infertility, and excess hair growth. But over time, researchers found something else. PMOS runs in families and not just among people with ovaries. They looked at the fathers and brothers of people with PMOS and found that they have some of the same underlying issues like being prone to weight gain, metabolic problems, and hormone differences. So now a new perspective is emerging that POS really isn't an ovary problem. It's more of a metabolic problem with hormonal ripple effects. And because this central metabolic issue can exist in anyone, men can show some of the same traits even without ovaries. So anyways, this name change is kind of the first step in reframing the condition and capturing some of its metabolic and endocrine features. And it's a change researchers hope will spark new studies and potential treatments for the
