Abstaining before IUI

Mi

Doesn't abstaining seem counterintuitive? I triggered on Friday night and will have <a href="https://glowing.com/glow-fertility-program">IUI</a> on Sunday morning. It feels like we should be having lots of sexy time, but clinic want us to hold off so there's a 48 hour growth of the sperm before hubby produces his sample. Anybody else feel odd about it?
