I've never looked at one, but I've thought about the idea. It doesn't appear to be a common practice in astrology. I assume that is because relatively few people can pinpoint their conception time accurately enough to yield anything very meaningful. Without the time you can get the sun and most of the planets, and about half the time you could get the moon. But if anything was near a cusp you wouldn't know, and you wouldn't have any house placements or aspects between things. It wouldn't be totally without merit, but it's the combination of all those very time-specific elements that really makes a chart unique. Without them you have the same chart as every other person conceived/born within about a 24 hour window within several degrees of latitude/longitude, which is a lot of people. The houses, moon, and any aspects relating to the moon move pretty quickly so you actually need a pretty fine pinpoint on the time to have it mean anything. Even when people tell you something like "I was born around 6 am" you have to treat some aspects of their chart as speculative.

The other thing that occurs to me is that beliefs vary about when the soul enters the fetus too. So I guess that would factor in to how meaningful a conception chart is to any given person also.
