If the spectator of Yerma's Eggs feels alienated or confused, as suggested in your feature " In vitro veritas " (THES, June 13), perhaps this is the intention of the theatre production and a strength rather than a weakness.

Yerma's Eggs is about exposure, not reassurance, so "clear narratives" and "clear conclusions" would be a betrayal of a production that courageously attempts to articulate a painful and personal process pursued by many women and men.

It is not a question of "chipping away at the prejudice of the sceptical middle-aged man in the video clip" about in vitro fertilisation but rather one of exploring it and of finding bridges that link a discourse of science to that of the feminine body in a less abrasive manner.

In performance terms, isn't this what Yerma's Eggs attempts to do?
