Material and methods: 22 14-week-old Holtzman female rats were selected, which were in the diestrus stage, determined by vaginal cytology evaluation, who were distributed into three groups, and treated orally for two days, as follows: Group control: physiological saline 1 ml/100g, experimental group 1: Ibuprofen 120 mg/kg/day and experimental group 2: Celecoxib 20 mg/kg/day. After two days they were mated with the males, until the end of the next estrous cycle. The rats were euthanized 10 days after separation from the male and the presence and number of implanted embryos were evaluated.
