In truth Natasha doesn't know what she could or couldn't give Clint. No doctor has ever checked that part of her biology out that she's aware of. Loki's words, however, make her pause. She'd never thought about children until that moment. She never asked Clint and they talk about everything.

Well, no. Not everything. She knows very little about details. His blood family, his brother, and his childhood for example. The archer doesn't tell her much, despite how much they talk.

"Children..." She states matter-of-factly. "Are not encouraged for agents of our level by SHIELD."
