	abstract = {Teaser stags and progesterone-PMS treatments were used to advance the breeding season in non-lactating adult red deer hinds. In Experiment 1, 2 vasectomised stags were run with 39 hinds for 15 d prior to joining with entire stags. More teased hinds (20/39) calved early (11-20 November ) than group of non-teased hinds (5/42). In other experiments, laparoscopy revealed that progesterone + PMS treated hinds ovulated in mid February. Although calves were born as early as 10 October, indicating stags could successfully fertilise a hind in mid February, such treatment did not result in many hinds calving in October. It seems that the stag is sub-fertile in February. Calving dates of contiguous control hinds show that a large proportion were mated 18 to 25 d after the induced oestrus in treated hinds indicating red deer stags can have an effect similar to the {\textquoteright}ram effect{\textquoteright}. Some hinds calving to the induced oestrus produced twins.},
