My experience is that about one in 20 examination gloves (not to be confused with surgical gloves) have a fault of some sort - breaking while being put on, unexpected size discrepancy, holes present already in the glove, deformed glove or adherent to another glove.
I must admit, however, that I am not a big glove wearer. Cringe if you will, but I do not wear gloves to examine groins, scrota, or feet. I only go to the trouble of donning them if there is an ulcer, wound, pus, or (potential) intertrigo (commonly known as skin-fold porridge). I am, however, an avid hand washer and user of alcoholic hand rubs.
I also do not wear gloves when putting in IVs or taking blood. A poorly fitting examination glove is completely useless to me as protection against a needlestick injury. If non-sterile surgical gloves were cheaply available I'd consider wearing them - but poor quality examination gloves only make my job more difficult and dangerous.
