Scientific evidence of reproduction urge?

Is there scientific evidence that animals have an innate/instinctual urge to reproduce? Is there scientific evidence that it is the same in humans?

Disclaimer: I'm not well educated in Biology. Or at least as much as I should be.
I've always believed there is, because it was always taught as a given, but I've never actually read any scientific studies to that effect. Is our opinion that all animals have an innate/instinctual urge to reproduce purely based on non-scientific evidence?
This question is sparked because my brother feels that animals actually only have an innate/instinctual urge to have sex and that reproduction is only a by-product, in that it's not intentional, either intellectually or innately/instinctually (and that with humans it's a bit different due to the intellectual aspect of it). I disagreed in that I always thought the urge was to reproduce and that sex was the by-product. I do agree though that I feel with humans it's a bit different due to the intellectual aspect...
I tried to google for some scientific evidence, but any mention of such urge is only in passing or editorial.
I'm fairly certain that I hold the majority viewpoint, so I don't just need people saying yes or no, this is right or that is right (although, viewpoints based on actual knowledge of the field are welcomed). What I'm wondering is if we can scientifically study that these urges exist, and if so, what have been the outcomes of such studies?
Sorry about how long-winded this is, but I just wanted to get this question out there.
