Ok guys, this is what I found:
"**The Institutio Generalis Missalis Romani (IGMR), the rules for celebration of Mass in the Roman Rite, explains the meaning of traditional Catholic gestures, genuflections and bows, indicating when these expressive gestures are to be assumed at Mass.
GENUFLECTIONS AND BOWS
274 A genuflection, which is made by bending the right knee to the ground, signifies adoration, and for this reason is reserved to the Most Blessed Sacrament and to the Holy Cross, from the solemn adoration in the liturgy of Good Friday until the beginning of the Easter Vigil.
Three genuflections are made during Mass by the priest celebrant: after the showing of the Eucharistic bread, after the showing of the chalice, and before Communion. Special features to be observed in a concelebrated Mass are noted in their proper place (see nos. 210-252).
If there is a tabernacle with the Blessed Sacrament in the sanctuary, the priest, deacon and other ministers genuflect to it when they approach or leave the altar, but not during the celebration of Mass itself. Otherwise, all who cross before the most Blessed Sacrament genuflect, unless they are involved in a procession.**"
The title for this is:
“
IGMR 274, 275:
Genuflection signifies adoration of Blessed Sacrament;
Bow means reverence & honor
[Page 5 of the March 2003 AB]”
The link, in case you’re interested is:

This seems to be pretty clear. The rubrics of the Mass are that the priest should genuflect at consecration.
Now what do we do?
