A - Thanks for the question. I am guessing that this is a follow-up to my post about In-vitro, which I recommend others read before I answer this question.
You are referring to the GIFT technique, which stands for "gamete intrafallopian transfer". It is a rarely used technique that is neither approved or disapproved by the Church. Here is the USCCB definition of the technique:
Nearly ripe ova are obtained from the woman's follicles by ultrasonically guided aspiration techniques as for IVF. But one ovum, separated with an air bubble from a prepared seminal fluid sample, is immediately reinserted with a plastic tubing into the woman's fallopian tube so that conception will occur within the body. Pregnancy rates are similar to IVF.The reason it is rarely used, is because it involves a surgical procedure, is more expensive than IVF, and doctors don't like doing it.
I am not sure what you mean by "an actual form of conception", but conception takes place within the women's body.
The USCCB website I linked to above has more info.
