With a tubal, a woman's eggs are still present, though they do not travel the usual path into the uterus. The body just absorbs them as they are released.

When a doctor takes a man's spem and a woman's egg and artificially creates conditions for conception and then implants the potential zygotes in the uterus, it is called in vitro fertilization (ivf). In vitro means outside the body or in an articificial environment, while normal conception resulting from sex could be called in vivo (in body). The costs may vary greatly depending on the doctor and exact process you use, but are generally expensive.

Also worthy to note, a doctor collecting a woman's eggs is a very arduous process for the woman. It involves injecting very heavy duty hormonal drugs (some of which are potential carcinogens) into the system everyday for several weeks, and can be very scary, intimidating or an otherwise big turn-off.

It cost alot to do what you are talking about
