The effect of prostaglandin synthetase inhibitors on human preovulatory follicular fluid prostaglandin, thromboxane, and leukotriene concentrations.
This study evaluates the eicosanoid concentration in luteinized unruptured follicles (LUFs) on the ovaries of patients who had been treated with inhibitors of prostaglandin synthetase. Indomethacin, bromfenac, or azapropazone (or a placebo) was administered orally to 41 women during the periovulatory period. Follicular development was monitored by serial ultrasound examinations, and the onset of ovulation was regulated by an injection of hCG. Follicular fluid was aspirated during sterilization by minilaparotomy, which was performed just before the expected time of ovulation. Prostaglandin E2 and PGF2 alpha levels in the fluid were significantly reduced by indomethacin and bromfenac compared to those after placebo treatment. Bromfenac also reduced the follicular fluid leukotriene B4 level. Therefore, the development of luteinized unruptured follicles after treatment with nonsteroidal antiinflammatory drugs appears to be associated with a significant decrease in the synthesis of ovarian eicosanoids.
