Nic ours was done under a light GA too. DH was with me till I went into theatre and then went upstairs to give his sample (usually this can be done at home but we had too far to travel so did ours at the clinic upstairs).

He was allowed to come in to recovery when I woke up and sat with me in the lounge while I had a cup of tea, some juice and biscuits etc then we went home.
