They certainly did in the West Country [Cornwall], in the UK, during the 1970s/1980s.
I was shown an illustrated article in Playboy or Penthouse from that time.
The fights were held in remote farming communities - usually in barns - with a ring made from bales of hay. Participants were usually buxom farm girls, wearing skimpy outfits..or none at all. The, mostly male, spectators bet on the fighters, who usually fought NHB-style, so there was quite a lot of blood.
To avoid the attentions of the police, details of the fights were passed by "word of mouth" among the trusted enthusiasts; and "lookouts" were posted by each lane, road, and footpath.
I don't know if they still take place these days.
