title: Rat ovarian prostaglandin levels and ovulation as indicators of the strength of non-steroidal anti-inflammatory drugs.
abstract: Immature Wistar rats were treated with pregnant mare's serum gonadotropin and human chorionic gonadotropin to induce ovulation. The non-steroidal anti-inflammatory drugs indomethacin, diclofenac, flurbiprofen, and phenylbutazone inhibited both the ovulation rate and the normal increase in ovarian prostaglandin E during ovulation. Tolmetin, ibuprofen, and aspirin did not have any significant effect. There was a significant correlation between the ovulation rate and the level of ovarian prostaglandin E following treatment with these drugs. When indomethacin was given in graded doses, there was also a correlation between ovulation rate and the dose-dependent inhibition of ovarian prostaglandin E.
