Why does semen trigger labor? #PregnancyTips, #LaborAndDelivery

[0:02]Hey egg. Guess who's back? Wait, there's a baby? Yeah, bro. I've been here nine months. Intruder detected. Room occupied. Uh. Why am I moving? Wait. Wait, why am I going down? Okay, okay, no panic. I just brought some prostaglandin favors. Bro, what does that mean? They soften the cervix. They trigger contractions. Translation, exit is opening. Wait, I haven't even picked a name yet. Okay, yeah, this escalated quick. I thought this was going to be a chill visit. This is not a casual environment. Contractions increasing. Why is the room hugging me so hard? Wait. I'm not ready for outside. Is it cold out there? I did not think this through. Final stage approaching. All systems aligned for delivery. No! I just got comfortable. Semen contains prostaglandins, which can help trigger labor, but don't worry, it's not a guaranteed fast pass ticket.
